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.

An organization has a widely distributed online environment, where applications are connected via WebSphere MQ messaging. A business requirement is brought forward that the delivery of certain persistent mission critical datagram messages needs to be recorded in a central location. The delivery information must not be lost. The mechanism used must not be dependent on cooperation of the receiving applications. Which of the following designs will meet these requirements?

• A. In the MQMD of the messages in question, COD and EXCEPTION reports will be requested;the resulting report messages will be delivered to the SYSTEM.ADMIN.REPORT.QUEUE onthe receiving queue manager.
• B. The sending application will put a copy of each message on a central queue reserved for thispurpose, including the completion code and reason code of the original request.
• C. In the MQMD of the messages in question, COD and EXCEPTION reports will be requested;the Reply-to queue fields point at a queue on a central queue manager reserved for thispurpose.
• D. In the MQMD of the messages in question, PAN, NAN and EXCEPTION reports will berequested; the Reply-to queue fields point at a queue on a central queue manager reservedfor this purpose.

There is concern about the security of an application data, so the solution designer is asked to explain what protection is available from SecureThere is concern about the security of an application? data, so the solution designer is asked to explain what protection is available from Secure Sockets Layer (SSL). Which of the following best describes the SSL support in base WebSphere MQ?

• A. confidentiality (data encryption)
• B. authentication, confidentiality (data encryption), integrity and non-repudiation
• C. authentication, confidentiality (data encryption) and integrity
• D. authentication and confidentiality (data encryption)

There are multiple instances of a cluster queue. Which of the following is recommended practice for the default binding (DEFBIND) parameter?

• A. Require the WebSphere MQ administrators to set default binding to the same value for allinstances of the queue in the cluster.
• B. Allow the local WebSphere MQ administrators to define default binding as they think best foreach instance of the queue.
• C. The best option is to accept the default setting for default binding on each queue manager, asit should have been given the optimal setting by its WebSphere MQ administrator.
• D. The solution designer should consult with the development team and local WebSphere MQadministrator to determine how best to configure default binding of each queue manager.
