NEW QUESTION # 67
What is default behavior for how theSalesforce B2B Commerce Global APIs transform Salesforce data?
- A. Fields names are returned with a lowercase first letter,camelcase convention
- B. Fields names are returned with ;c." prepended in their name.
- C. Fields names can be mapped to any naming convention desired
- D. Fields names are returned using the Salesforce naming convention.
Answer: A
Explanation:
The default behavior for how the Salesforce B2B Commerce Global APIs transform Salesforce data is to return field names with a lowercase first letter, camelcase convention. For example, the field name ccrz__E_Product__c in Salesforce will be transformed to eProduct in the API. This is done to follow the JavaScript naming convention and to avoid conflicts with the standard Salesforce fields and relationships.

NEW QUESTION # 68
A developer is building a custom component in Lightning web components (LWC) that needs to fetch data from an API.
Which lifecycle hook should the developer use to make the API call?
- A. errorCallback
- B. connectedCallback
- C. disconnectedCallback
- D. renderedCallback
Answer: B
Explanation:
To make an API call in a Lightning web component (LWC), a developer should use the connectedCallback lifecycle hook. The connectedCallback lifecycle hook is invoked when the component is inserted into the DOM. This is the ideal time to make an API call, as the component is ready to receive and display data. The developer can use the fetch API or a third-party library, such as axios, to make the API call and handle the response. The renderedCallback lifecycle hook is not a good choice for making an API call, as it is invoked every time the component is rendered or rerendered. This can cause unnecessary or repeated API calls and affect performance. The errorCallback lifecycle hook is not a good choice either, as it is invoked when an error occurs in the component or in one of its children. This is not related to making an API call, but rather to handling errors. The disconnectedCallback lifecycle hook is not a good choice either, as it is invoked when the component is removed from the DOM. This is not a suitable time to make an API call, as the component is no longer visible or active.

NEW QUESTION # 69
Which two statements are true regarding the cc_CallContext class in Salesforce B2B Commerce? (2 answers)
- A. The class can be used internally within Salesforce B2B Commerce and in subscriber code to access context level parameters
- B. The Salesforce session is accessible via the getSession method
- C. The userLocale variable returns the current Locale for storefront.
- D. The current storefront is accessible via thisclass
Answer: A,D
Explanation:
The cc_CallContext class is a utility class that provides access to various context level parameters, such as the current storefront, user, cart, price list, currency, locale, and session. The class can be used internally within Salesforce B2B Commerce and in subscriber code to access these parameters. The current storefront is accessible via this class by using the getStorefront method, which returns a cc_Storefront__c object. The userLocale variable returns the current Locale for storefront, but it is not part of the cc_CallContext class. It is a global variable that can be accessed from any Visualforce page or component by using {!userLocale}. The Salesforce session is accessible via the getSession method, but it is not part of the cc_CallContext class either. It is a method of the cc_SessionUtil class, which is another utility class that provides methods for managing sessions. Salesforce Reference: [B2B Commerce Developer Guide: cc_CallContext Class], [B2B Commerce Developer Guide: cc_SessionUtil Class]
NEW QUESTION # 70
Which handlebars helper expression is used in Salesforce B2B Commerce pages and components to toggle the display of a block of markup?
- A. {{#ifConfig 'Field__c'}} ... {{/ifConfig}}
- B. {{#ifStoreSetting 'Field__c'}} ... {{/ifStoreSetting}}
- C. {{#ifSetting 'Page.cfg}} ... {{/ifSetting}}
- D. {{#ifDisplay 'Page.cfg'}} ... {{/ifDisplay}}
Answer: A
Explanation:
The handlebars helper expression that is used in Salesforce B2B Commerce pages and components to toggle the display of a block of markup is {{#ifConfig 'Field__c'}} ... {{/ifConfig}}. This expression will evaluate the value of the configuration setting with the API name Field__c and render the block of markup if the value is true, or skip it if the value is false. For example, {{#ifConfig 'CO.showMiniCart'}} <div id="mini-cart"> ... </div> {{/ifConfig}} will render the mini-cart div only if the configuration setting CO.showMiniCart is true. Salesforce Reference: B2B Commerce and D2C Commerce Developer Guide, Handlebars Helpers
NEW QUESTION # 71
A developer has made a component with a lightning combobox in the follow! markup. To handle changes on the combobox, what should replace <CHANGE FVENT>?
- A. {handleChange()}
- B. javascript:void(0);handleChange();
- C. {event:handleChange}
- D. {handleChange}
Answer: D
Explanation:
To handle changes on the combobox, the developer should replace <CHANGE EVENT> with {handleChange}. The handleChange is a function that is defined in the JavaScript file of the Lightning web component and is invoked when the value of the combobox changes. The developer can use this function to perform custom logic or actions based on the selected value of the combobox, such as updating other components or properties, calling Apex methods or services, or firing events. The developer can use the onchange attribute to bind the handleChange function to the combobox element in the HTML file of the Lightning web component. The onchange attribute is an HTML attribute that specifies a function to be executed when the value of an element changes. {event:handleChange} is not a valid way to handle changes on the combobox, as it is not a valid syntax for binding a function to an element. javascript:void(0);handleChange(); is not a valid way either, as it is not a valid syntax for binding a function to an element. {handleChange()} is not a valid way either, as it is not a valid syntax for binding a function to an element. Salesforce Reference: Lightning Web Components Developer Guide: Handle Events, Lightning Web Components Developer Guide: Communicate with Properties, Lightning Web Components Developer Guide: lightning-combobox
NEW QUESTION # 72
Which three attributes are true regarding Subscriber pages? (3 answers)
- A. Subscriber pages allow customers to quickly create new custom pages for their storefront.
- B. Standard Salesforce B2B Commerce components are automatically included on the page e.g. Header links, images, menu items, containers, etc.
- C. Subscriber pages can include additional standard Salesforce B2B Commerce components such as featured products, category tree, and mini cart.
- D. Out of the Box, Subscriber Pages are completely blank HTML pages.
- E. All the user interface components must be created manually.
Answer: A,B,C
NEW QUESTION # 73
Which three statements are true about Global API versioning? (3 answers)
- A. Calling in with an API version set to more than current maximum will result in exception case where the exception class ccrz.ExceedsMaxAPIVersionException will be returned to callers.
- B. There is no need to pass API_VERSION to the Global APIs, and based on the Salesforce B2B Commerce Managed Package version, Global APIs are able to figure out what version of the API to use.
- C. Minimum API_VERSION is 1 and the Maximum API version follows the releases. E.g. The maximum was 4 as of Salesforce B2B Commerce Release-4.5, 5 as of Salesforce B2B Commerce Release 4.6, etc.
- D. The API version is scoped at the Class API level and NOT at the method level.
- E. Calling in with an API version set to lower than 1 will result in an exceptional case where the exception class ccrz.BelowMinAPIVersionException will be returned to callers.
Answer: A,C,E
NEW QUESTION # 74
Which two usages of ccLog should be avoided in Salesforce B2B Commerce? (2 answers)
- A. crz.ccLog.log(System.LoggingLevel.DEBUG, 'D:myOrderList', myOrderList), where myOrderList is a list of orders
- B. ccrz.ccLog.log(System.LoggingLevel.ERROR, 'D:something', myCallToGetMessage(pl) ), where myCallToGetMessage(pl) is a method invocation
- C. crz.ccLog.log(System.LoggingLevel.DEBUG, 'D:myOrder', myOrder), where myOrder is an order object
- D. crz.ccLog.log(System.LoggingLevel.WARN, 'D:something', 'Something unexpected occurred: The data we were expecting for pl was not there,')
Answer: A,B
Explanation:
You should avoid using ccLog in two scenarios. First, you should avoid using ccLog with System.LoggingLevel.ERROR when passing in a method invocation as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.ERROR, 'D:something', myCallToGetMessage(pl) ). This is because if an exception occurs within the method invocation, it will not be caught by ccLog and will cause an unhandled exception on the page. Instead, you should use a try-catch block around the method invocation and log the exception separately. Second, you should avoid using ccLog with System.LoggingLevel.DEBUG when passing in a large collection or object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, 'D:myOrderList', myOrderList), where myOrderList is a list of orders. This is because logging large objects can cause performance issues and consume a lot of heap space. Instead, you should use a loop to log only the relevant fields or properties of the object or collection. You can use ccLog with System.LoggingLevel.WARN when passing in a string as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.WARN, 'D:something', 'Something unexpected occurred: The data we were expecting for pl was not there,'). This is a valid use case for logging a warning message. You can also use ccLog with System.LoggingLevel.DEBUG when passing in a small object as the third parameter, such as ccrz.ccLog.log(System.LoggingLevel.DEBUG, 'D:myOrder', myOrder), where myOrder is an order object. This is acceptable as long as the object is not too large or complex. Salesforce Reference: [B2B Commerce Developer Guide: Logging]
NEW QUESTION # 75
What two kinds of queries do the methods in Salesforce B2B Commerce services perform by default? (2 answers)
- A. SQL
- B. SOSL
- C. SOQL
- D. Schema-less queries
Answer: C,D
Explanation:
Two kinds of queries that the methods in Salesforce B2B Commerce services perform by default are SOQL and schema-less queries. SOQL is the query language that is used to retrieve data from Salesforce objects and fields. Schema-less queries are queries that do not specify the object or field names explicitly, but use placeholders instead. For example, ccrz.ccServiceDao.getQuery('SELECT Id FROM Account WHERE Name = :name') is a schema-less query that uses :name as a placeholder for the field name. The framework will transform this query to use the actual field name based on the query transformation rules. Salesforce Reference: B2B Commerce and D2C Commerce Developer Guide, Query Transformation
NEW QUESTION # 76
Which service method should be overridden in order to allow "without sharing" queries?
- A. ccrz.ccAPI.queryService()
- B. ccrz.ccService.initSVCDAO()
- C. ccrz.ccService.query()
- D. ccrz.ccService.queryWithoutSharing()
Answer: B
NEW QUESTION # 77
A developer has the task to bring some historical data into an org. The data must reside in the org, but cannot be populated in standard or custom objects. The customer is fine with developers building Ul components to surface this data on a case-by-case basis.
Which option allows a developer to meet all of these requirements?
- A. Big objects
- B. External objects
- C. Lightning Out
- D. Lightning Canvas
Answer: A
Explanation:
To bring some historical data into an org, the data must reside in the org, but cannot be populated in standard or custom objects, and the customer is fine with developers building UI components to surface this data on a case-by-case basis, the option that allows a developer to meet all of these requirements is big objects. Big objects are a type of object that can store and manage massive amounts of data on the Salesforce platform. Big objects can store up to billions of records and are accessible through a subset of SOQL or custom user interfaces. Big objects are not subject to the same storage limits or performance issues as standard or custom objects and are suitable for storing historical or archived data that does not need to be updated frequently. Big objects can be defined using Metadata API or declaratively in Setup. Lightning Canvas is not an option that allows a developer to meet all of these requirements, as it is a framework that allows developers to integrate third-party applications into Salesforce. Lightning Canvas does not store data in the org, but rather displays data from external sources using an iframe. External objects are not an option either, as they are a type of object that map to data stored outside Salesforce. External objects do not store data in the org, but rather access data from external systems using OData services. Lightning Out is not an option either, as it is a feature that allows developers to use Lightning components outside Salesforce. Lightning Out does not store data in the org, but rather renders components on external web pages or applications. Salesforce Reference: Salesforce Help: Define Big Objects, Salesforce Help: Lightning Canvas Developer's Guide, Salesforce Help: External Objects, Salesforce Developer Blog: Lightning Out
NEW QUESTION # 78
Which two event settings are required for a custom event called CustomEvent to fire from the Lightning web component and propagate up to the DOM?
- A. composed: true
- B. composed: false
- C. bubbles: true
- D. cancelable: true
Answer: A,C
Explanation:
To fire a custom event called CustomEvent from the Lightning web component and propagate it up to the DOM, the developer must set two event settings: bubbles and composed. The bubbles setting determines whether the event bubbles up through the component's ancestors in the DOM tree. The composed setting determines whether the event crosses the shadow boundary and reaches the light DOM. Setting both bubbles and composed to true allows the event to be handled by any element in the DOM that listens for it. The cancelable setting is not required for firing or propagating the event, as it only determines whether the event can be canceled by calling preventDefault() on it. Setting composed to false would prevent the event from reaching the light DOM and limit its propagation to the shadow DOM. Salesforce Reference: Lightning Web Components Developer Guide: Create and Dispatch Events, Lightning Web Components Developer Guide: Event Propagation
NEW QUESTION # 79
Which two scoped modules should a developer import in Lightning web components to check user permissions?
- A. @salesforce/userPermission
- B. @salesforce/customPermission
- C. @salesforce/hasPermission
- D. @salesforce/permission
Answer: B,D
Explanation:
To check user permissions in Lightning web components, a developer should import two scoped modules: @salesforce/permission and @salesforce/customPermission. The @salesforce/permission module allows the developer to check if the user has access to a standard permission, such as View Setup or Modify All Data. The @salesforce/customPermission module allows the developer to check if the user has access to a custom permission, such as Enable Debug Mode or Manage Orders. The other modules do not exist or are not related to user permissions. Salesforce Reference: Lightning Web Components Developer Guide: Check User Permissions, Lightning Web Components Developer Guide: Import Salesforce Modules
NEW QUESTION # 80
Which three actions are applicable when modifying the number of steps required in the Salesforce Commerce Checkout flow? (3 answers)
- A. Perform a template override on the Checkout page.
- B. Set the value of the configuration setting defined as CO.useDef to TRUE
- C. Add a page include to the checkout page.
- D. Set the value of the configuration setting defined as CO.overrideFlow to TRUE.
- E. Build and activate a new configuration cache setting via CC admin.
Answer: A,D,E
Explanation:
Three actions that are applicable when modifying the number of steps required in the Salesforce Commerce Checkout flow are:
Perform a template override on the Checkout page. This action will allow you to change the structure and content of the Checkout page, such as adding or removing sections, widgets, or fields. For example, you can override the checkout.handlebars template and modify it according to your requirements.
Set the value of the configuration setting defined as CO.overrideFlow to TRUE. This setting will enable you to use your own custom checkout flow instead of the default one. You need to set this value to true before you can modify the checkout flow.
Set the value of the configuration setting defined as CO.useDef to TRUE. This setting will enable you to use a single-page checkout flow instead of a multi-step checkout flow. You need to set this value to true if you want to reduce the number of steps in the checkout flow to one. Salesforce Reference: B2B Commerce and D2C Commerce Developer Guide, Checkout Flow
NEW QUESTION # 81
Which code statement should a developer use to import the ID of the current Lightning Experience
- A. import id from '@salesforce/network/ld'
- B. import id from '@salesforce/experience/ld'
- C. import id from '@salesforce/site/ld'
- D. import id from '@salesforce/community/ld'
Answer: D
Explanation:
To import the ID of the current Lightning Experience community, a developer should use the following code statement:
import id from '@salesforce/community/Id';
The @salesforce/community module allows the developer to access information about the current community, such as its ID, name, URL, and base path. The other modules do not exist or are not related to the community ID. The @salesforce/network module is used to access information about the current network, such as its ID and name. The @salesforce/experience module is used to access information about the current user experience, such as whether it is standard or custom. The @salesforce/site module is used to access information about the current site, such as its name and prefix. Salesforce Reference: [Lightning Web Components Developer Guide: Import Community Information], [Lightning Web Components Developer Guide: Import Salesforce Modules]
NEW QUESTION # 82
Which wire adapter should a developer use to retrieve metadata about a specific object?
- A. getObjectlnfo
- B. getObject
- C. getObjectDescribe
- D. getObjectMetadata
Answer: A
Explanation:
To retrieve metadata about a specific object, a developer should use the getObjectInfo wire adapter. The getObjectInfo wire adapter imports data from the @salesforce/schema module and returns an object that contains information such as the object's label, key prefix, fields, child relationships, record type infos, and theme. The getObjectMetadata wire adapter does not exist. The getObject wire adapter does not retrieve metadata, but rather returns a record object based on the record ID. The getObjectDescribe wire adapter does not exist either. Salesforce Reference: [Lightning Web Components Developer Guide: getObjectInfo], [Lightning Web Components Developer Guide: Import Salesforce Schema]
NEW QUESTION # 83
A developer is working in Visual Studio Code on a previously deployed project which is rather large and deployments are time consuming. The developer wants to deploy some small CSS changes without waiting for the entire project deployment. What are two ways this can be accomplished?
- A. Right-click the CSS file and choose Deploy Source to Org
- B. Right-click the CSS file that was edited and select Deploy Single File
- C. Click the Tools menu and select Deploy styles
- D. Deploy the entire project. Only the change will be copied
- E. Right-click the folder for the component and choose Deploy Source to Org
Answer: B,E
Explanation:
Two ways that a developer can deploy some small CSS changes without waiting for the entire project deployment are right-clicking the folder for the component and choosing Deploy Source to Org and right-clicking the CSS file that was edited and selecting Deploy Single File. Deploying source to org is a way of deploying metadata from a local project to an org using Salesforce CLI commands. The developer can use Visual Studio Code to execute these commands by right-clicking on files or folders in the project and choosing from various deployment options. Right-clicking the folder for the component and choosing Deploy Source to Org allows the developer to deploy only the files that belong to that component, such as HTML, JavaScript, CSS, and XML files. Right-clicking the CSS file that was edited and selecting Deploy Single File allows the developer to deploy only that CSS file and not any other files in the project. These options can save time and bandwidth for deploying small changes without affecting other components or files in the project. Modifying the StoreIntegratedService to map to an Apex class ID using Workbench is not a way of deploying CSS changes, as it is only used for registering internal services that are provided by Salesforce B2B Commerce out-of-the-box. Entering the integration class name and version in store administration is not a way of deploying CSS changes either, as it is only used for selecting an existing integration class that has already been registered as an external service.

Answer: C,D
NEW QUESTION # 85
Which method signature is used in the Global API's?
- A. Changes based on API and Method name
- B. Map<String, Object>
- C. List<List<Object>>
- D. ccrz.cc_Output (ccrz:cc_Input input)
Answer: D
Explanation:
The method signature that is used in the Global API's is ccrz.cc_Output (ccrz.cc_Input input). This signature indicates that the Global API methods take a single input parameter of type ccrz.cc_Input and return an output of type ccrz.cc_Output. These are custom classes that are defined in the cloudcraze managed package and contain various properties and methods for handling the input and output data. For example, ccrz.ccServiceProduct.getProducts(ccrz.cc_Input input) is a Global API method that takes an input object and returns an output object containing product data.

NEW QUESTION # 86
A developer needs to implement specific styling for a standard component on a single page of the B2B Commerce store using an Aura template. The component should use the default style on all other pages How should the developer implement the required changes over multiple instances?
- A. Use the Override CSR Editor in the Experience Builder and add the desired CSS to change the styles.
- B. Create a Custom Content Layout Lightning web component that imports the custom CSS file. Set up the page to use this Content Layout.
- C. Create a Custom Theme Layout Aura component that imports the custom CSS file. Set up the page to use this Theme Layout.
- D. Use a Custom CSS file in a static resource and add the import using the Edit Head Markup Editor in the Experience Builder.
Answer: C
Explanation:
To implement specific styling for a standard component on a single page of the B2B Commerce store using an Aura template, a developer should create a custom theme layout Aura component that imports the custom CSS file and set up the page to use this theme layout. A theme layout is a type of Aura component that defines the header and footer of a page in the storefront. A theme layout can also import custom CSS files from static resources and apply them to the page. A developer can create a custom theme layout Aura component that imports the custom CSS file that contains the specific styling for the standard component and assign it to the page that needs the custom styling. This way, the custom styling will only affect the standard component on that page and not on other pages that use a different theme layout. Using a custom CSS file in a static resource and adding the import using the Edit Head Markup Editor in the Experience Builder is not a valid way to implement specific styling for a standard component on a single page, as it will affect all pages that use the same template. Creating a custom content layout Lightning web component that imports the custom CSS file and setting up the page to use this content layout is not a valid way either, as it will not affect the standard component that is outside of the content layout. Using the Override CSR Editor in the Experience Builder and adding the desired CSS to change the styles is not a valid way either, as it will affect all pages that use the same template.

NEW QUESTION # 87
Which three statements are true regarding event handling in the Salesforce B2B Commerce managed package? (3 answers)
- A. Salesforce B2B Commerce relies on a central event channel for communication across various Salesforce B2B Commerce Backbone Views and Models called CCRZ.pubSub.
- B. CCRZ.pubSub defines the following three functions which can be used for event handling: trigger, on, and once.
- C. Writing directly to your own custom Backbone JS Views and Models automatically integrates that data into the Salesforce B2B Commerce Backbone Views and Models.
- D. Salesforce B2B Commerce relies on a series of Javascript click listener events.
- E. CCRZ.pubSub extends the Backbone.Events JavaScript object.
Answer: A,B,E
Explanation:
Three statements that are true regarding event handling in the Salesforce B2B Commerce managed package are:
Salesforce B2B Commerce relies on a central event channel for communication across various Salesforce B2B Commerce Backbone Views and Models called CCRZ.pubSub. This object allows different components to publish or subscribe to events without being coupled with each other. For example, CCRZ.pubSub.trigger('cartChange') will publish an event named cartChange that can be subscribed by any component that needs to react to it.
CCRZ.pubSub defines the following three functions which can be used for event handling: trigger, on, and once. The trigger function is used to publish an event with a name and optional arguments. The on function is used to subscribe to an event with a name and a callback function. The once function is similar to on, but it will only execute the callback function once for each event.
CCRZ.pubSub extends the Backbone.Events JavaScript object. This object provides methods for managing events in Backbone.js, which is a JavaScript framework that provides models, views, collections, and events for building single-page applications. CCRZ.pubSub inherits all the methods and properties of Backbone.Events and adds some custom ones. Salesforce Reference: B2B Commerce and D2C Commerce Developer Guide, Events, PubSub Class

NEW QUESTION # 90
How should data for Lightning web components be provided?
- A. A single property object that contains sets (objects) of data
- B. One property that contains all data in one set (object)
- C. Independent properties that take simpler, primitive values (e.g. String, Number, Boolean, Array)
- D. A few properties that contain sets (objects) of data
Answer: C
Explanation:
Data for Lightning web components should be provided as independent properties that take simpler, primitive values (e.g. String, Number, Boolean, Array). Providing data as independent properties allows the developer to expose data as public or private properties of the Lightning web component and communicate data between components or services. Providing data as simpler, primitive values allows the developer to use data types that are supported by JavaScript and Lightning web components and avoid unnecessary or complex conversions or transformations. Providing data as a few properties that contain sets (objects) of data is not a good way to provide data for Lightning web components, as it can create confusion or inconsistency in data structure and access. Providing data as one property that contains all data in one set (object) is not a good way either, as it can create complexity or inefficiency in data management and manipulation. Providing data as a single property object that contains sets (objects) of data is not a good way either, as it can create redundancy or duplication in data storage and retrieval.
