IBM WebSphere MQ V7.0, Solution Design (C9530-376) Free Practice Test

Question 1

An application is required to retrieve rows from a relational database table and send them across WebSphere MQ to a remote queue manager, where a receiving application consumes them.
After a successful MQPUT of a message, the corresponding row is to be deleted from the database. It is intended to run this application using the free WebSphere MQ Client. The delivery of each message is to be guaranteed. Which of the following is true about this implementation?

A. It cannot be done using the free WebSphere MQ Client; the Extended Transactional Client is required, since two phase commits are needed for this solution.

B. It cannot be done using the free WebSphere MQ Client; a local queue manager is required to support the guaranteed delivery of the messages.

C. This solution cannot be implemented using the free WebSphere MQ Client; persistent messaging is not supported by the free WebSphere MQ Client.

D. This solution can be implemented using the free WebSphere MQ Client, provided that the receiving application can recognize and handle repeated delivery of the same message.

Correct Answer: D

Question 2

Queue Managers QMA and QMB both have a cluster queue definition for Q1. A sending application resides on QMC, which is also part of the cluster. The messages being sent from QMC contain data from the same account that needs to be processed at the destination (Q1) in the same order that the messages were sent. Which one of the following is MOST LIKELY to enforce the sending order on the destination queue, assuming the message can be routed to the destination queue?

A. The sending application sends the messages for the account within the same unit of work

B. Q1 is defined with DEFBIND(OPEN) and the sending application opens Q1 and sends themessages for the account

C. The sending application specifies the destination Queue Manager and Queue name on theopen for Q1 and sends the messages for the account

D. The sending application opens Q1 with MQOO_BIND_ON_OPEN and sends the messages forthe account

Correct Answer: D

Question 3

A server application needs to record a unique id from the user who has created a request message in the Windows environment. Which MQMD field contains this information?

A. ApplOriginData

B. ApplIdentityData

C. UserIdentifier

D. AccountingToken

Correct Answer: D

Question 4

A company utilizes virtualization technologies and frequently moves workloads between servers and data centers. A WebSphere MQ solution designer is attempting to plan the MQ naming standards, and wants to provide for the greatest level of architectural flexibility and portability. Which of the following is NOT a recommended best practice to meet these goals?

A. Use generic names for MQ objects inside applications to avoid hard-coding the actual names.

B. Use alias queues and/or model queues with the application configuration.

C. Use a configuration file for the application which contains the environment specific queuenames.

D. Use full uppercase for all objects and avoid forward slash (/) and percent (%) specialcharacters, to prevent portability issues.

Correct Answer: C

Question 5

A publish/subscribe application is being designed. The requirements are that the published information should not be lost or expire. The subscriber application will connect periodically during the day to process the publications. Which publish/subscribe feature(s) are most appropriate for this type of application?

A. Retained publications

B. Durable subscriber

C. Nondurable subscriber

D. Nondurable subscriber with retained publications

Correct Answer: B

Question 6

A solution developer needs to promote newly developed applications from the development environment through the user acceptance test environment and into the production environment. Which of the following will best avoid issues with naming conventions for application-owned permanent queues?

A. A standard should be implemented by which all queue names will be prefixed with the queue manager name, which will begin with the strings EV? AT?or RD? respectively, to indicate the current environment. Applications will have to amend queue names accordingly before?EV? ?AT?or ?RD? respectively, to indicate the current environment. Applications will have to amend queue names accordingly before opening the queues.

B. WebSphere MQ clustering should be used to resolve queue names and locations dynamically.

C. The alias queue names used in the application code will be prefixed with EV? AT?or RD? respectively, so that applications can beThe alias queue names used in the application code will be prefixed with ?EV? ?AT?or ?RD? respectively, so that applications can be promoted between environments without having to change the queue names.

D. The names should be identical across the various environments, so that no changes to applications or object definitions between queue managers are required during promotion.

Correct Answer: D

Question 7

A company would like to expand their services to accept incoming orders from external partners.
Some of the external partners already use WebSphere MQ, and the others could install WebSphere MQ or run a WebSphere MQ client. The company is concerned about significantly increasing the number of channels into their queue manager as a result of connecting to so many new external partners. Which of the following could reduce this concern?

A. Use WebSphere MQ Cluster channels to limit the interconnectivity

B. Use DataPower XI50 to handle some of the external traffic and forward the messages to thequeue manager

C. Use WebSphere MQ Internet Passthru to act as a channel concentrator for the queuemanager

D. Use shared conversations to reduce the number of connections to the queue manager

E. Use SSL to encrypt the channels

Correct Answer: B,C

Question 8

An application creates documents in PDF format, which are subsequently transmitted via WebSphere MQ to a number of other servers in the network. Each server runs its own queue manager. The documents received by some servers are consistently corrupted, whereas on other servers the documents are intact. Other message traffic seems unaffected. What is the most likely source of this problem?

A. The environment variable MQCCSID specifies an incorrect value on the affected servers.

B. The network connection to the affected servers is unreliable and a message retry exit was not specified on the sending channel agent.

C. The affected servers run different CCSIDs from the servers creating the documents and the message descriptor specifies MQMFormat as QSTR? causing message conversion.?QSTR? causing message conversion.

D. Incompatible message compression parameters are configured on the sending and receiving channel agents.

Correct Answer: C

Question 9

An application receives messages created on Windows workstations and, after doing transformations, forwards them to a target system running on z/OS. There is a requirement for passing the original username, but information about the date and time associated with the message should be set by the forwarding application. What is the best way of doing this?

A. Use MQPMO_SET_IDENTITY_CONTEXT on Windows and MQPMO_PASS_IDENTITY_CONTEXT in the forwarding application

B. Use MQPMO_DEFAULT_CONTEXT on Windows and MQPMO_PASS_IDENTITY_CONTEXT in forwarding application

C. Use MQPMO_DEFAULT_CONTEXT on Windows and MQPMO_PASS_ALL_CONTEXT in the forwarding application

D. Use MQPMO_SET_IDENTITY_CONTEXT on Windows and MQPMO_PASS_ALL_CONTEXT in the forwarding application

Correct Answer: B

Question 10

An application needs to display the last published message every five minutes. What is the best way of doing this?

A. Use MQSUB with MQSO_NEW_PUBLICATIONS_ONLY and call MQSUBRQ every five minutes.

B. Use MQSUB with MQSO_PUBLICATIONS_ON_REQUEST and call MQSUBRQ every five minutes.

C. Use MQSUB with MQSO_PUBLICATIONS_ON_REQUEST option and SubExpiry set to 300.

D. Use MQSUB with SubExpiry set to 300.
