Question 1

A solution designer is looking to utilize industry standard technologies but does not want to settle for the qualities of service that HTTP offers. Which of the following is not a benefit of using SOAP/WebSphere MQ over SOAP/HTTP?

A. Integration with, and reuse of, existing WebSphere MQ infrastructure

B. Assured delivery

C. Ability to provide access to legacy applications

D. WebSphere MQ clustering for load balancing and enhanced reliability and availability

Correct Answer: C

Question 2

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 3

A company has an existing point to point application written in C that distributes delivery status to queue Q1. They want to change the distribution to publish/subscribe so that other applications can subscribe to the delivery status information. Which of the following ways of changing to WebSphere MQ publish/subscribe will work with the least recoding?

A. Change the sending application program to use the WebSphere MQ publish/subscribe APIinstead of point to point

B. Run WebSphere MQ in PSMODE=COMPAT

C. Change the sending application program to use WebSphere MQ publish/subscribe commandsin RFH2 headers instead of the point to point API

D. Set up a queue alias for Q1 that is an alias for a subscription topic

Correct Answer: D

Question 4

Which of the following contains the best mix of items to utilize in a queue name?

A. Queue Purpose, Object Type, Function

B. Application Identifier, Function

C. Environment Identifier, Object Type, Application Identifier

D. Application Identifier, Environment Identifier, Location

Correct Answer: B

Question 5

A customer has an environment where applications are frequently redeployed to different servers
to react to changing capacity needs. Which of the following will provide the best support for the affected applications to be moved?

A. Affected applications will be linked with the MQ Client interface and will maintain connectionsto all affected queue managers simultaneously; they will then find the respective queues byquerying the queue managers.

B. Affected applications will connect to default queue managers and use generic, locationindependent queue names only; a set of alias and remote queue definitions are used in thequeue managers to connect applications to where the real queues are at any point in time.Input queues need to move with the owning applications.

C. Affected applications will first connect to a central queue manager via the WMQ client interfacewhere they can find configuration information in a special queue; they then open theirrespective application queues accordingly.

D. Affected applications will read configuration files from their local file system that are updatedby administrators to reflect the new locations of destination queues; they then have todynamically build the appropriate queue names before opening the queues.

Correct Answer: B

Question 6

A solution designer is looking to implement a robust failover mechanism as part of a solution, and has decided on utilizing HACMP on AIX. What must be considered when designing the application?

A. WebSphere MQ clustering should be utilized to cluster the queues between the two server nodes.

B. The application needs to be designed to run on multiple servers, and needs to handle heartbeats between application instances.

C. The architecture should be designed to process duplicate transactions in cases where a failover needs to occur.

D. Application log and state information should be stored on shared disk.

Correct Answer: D

Question 7

A business requirement is brought forward for a back end server that is to send replies to requests sourced on the web and on internal application servers. The back end application will perform database lookups and formatting operations that are deemed trivial. Message sizes, traffic volumes and estimated annual growth rates are provided. The application designer is asked to provide a sizing estimate for a server that will be able to provide the response times stipulated in the SLA. Which is the fastest way to arrive at a reasonable estimate of the required server size?

A. Meaningful performance measurements can only be done once the application developmenthas progressed to the point where the actual code can be benchmarked.

B. Create a suitable test program and test clients and perform a series of benchmarks on anavailable server.

C. Collect performance statistics from other WebSphere MQ based applications and extrapolatethe findings to your requirements.

D. Consult the Performance Reports from the WebSphere MQ SupportPac website forcomparable measurements and extrapolate to the specified requirements.

Correct Answer: D

Question 8

A company has a large network of WebSphere MQ clustered queue managers that span multiple applications. When migrating such a cluster to a new version, which one of the following is a good practice?

A. Perform a staged migration, in which queue managers are migrated one at a time.

B. At a minimum, migrate the full repositories at the same time, to avoid incompatibilities in thedefinitions that they store.

C. Stage the migration, but migrate all the queue managers on a particular operating system atthe same time.

D. Migrate all the queue managers in the cluster at the same time to make sure there are noincompatibilities between versions.

Correct Answer: A

Question 9

The business wants to alert administrators and business owners to any service disruptions as soon as possible. This is to include any applications that receive request messages on input queues and have to respond to them as quickly as possible. The ideal solution will not introduce significant overhead to the environment. The WebSphere MQ solution designer is asked to evaluate the available features in WebSphere MQ that can be used to address this requirement.
Which of the following is the most responsive mechanism to address outages as soon as they develop?

A. Activity Recording

B. Queue depth events

C. Trace Route messages

D. Queue service interval events

Correct Answer: D

Question 10

Business owners want to allow an existing application to be easily portable to any of four Linux servers in a cluster. For this, they want the four queue managers to be changed to have the same name. What must be the response of the WebSphere MQ Solution Designer?

A. There is no problem.

B. It is possible to define queue managers with identical names in a cluster, but it is notrecommended.

C. It cannot be done. The repository will reject duplicate queue managers.

D. Queue managers cannot be renamed, so this can only be done by recreating the queuemanagers. Beyond that, there is no problem.
