A new version of the application running on queue manager LONDON10 in cluster EUROPA is going to be installed. During the scheduled change window, backups will be taken for LONDON10, and then the application will be upgraded. To prepare the queue manager before the start of the maintenance window, a command should be issued for LONDON10 to do which of the following?

• A. Stop the connection to cluster EUROPA
• B. Suspend the queue manager from cluster EUROPA.
• C. Resume the queue manager in cluster EUROPA
• D. Refresh the queue manager in cluster EUROPA and include the REPOS(NO) parameter

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. Migrate all the queue managers in the cluster at the same time to make sure there are noincompatibilities between versions.
• 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. Perform a staged migration, in which queue managers are migrated one at a time.

In designing a solution with availability in mind, the designer is considering the following two alternatives, one using a cluster queue and the other using a shared queue. In each scenario, Queue Managers QMA and QMB will both be capable of running Application A.
In the first scenario, Application A will run on QMA and QMB on Windows accessing cluster queue QA. In the second scenario, Application A will run on QMA and QMB on z/OS accessing shared queue QA. Which of the following describes the availability scenarios in the situation where QMA fails?

• A. For z/OS, messages from QA that were in flight on QMA when it failed are unavailable for processing by QMB
• B. For Windows, messages from QA that were in flight on QMA when it failed are made available for processing on QMB
• C. For Windows, the delivered messages on QA that Application A on QMA did not get to process are available for processing by Application A on QMB
• D. For z/OS, the delivered messages on QA that Application A on QMA did not get to process are available for processing by Application A on QMB

A weather bureau plans to offer a service to its customers whereby they can receive weather station information (e.g. temperature, humidity) up to one year old. Customer applications should be able to select from which region they want to get datA. What is the best way of implementing such a solution?

• A. Store information in a database and access it using a publish/subscribe pattern
• B. Store messages in separate queues for each region and use a scheduled process to deleteoutdated messages
• C. Store messages in separate queues for each region and use the expiration feature of themessaging system to delete outdated messages
• D. Store information in a database and access it using a request-reply pattern

Client applications are sending requests which are stored in a common queue. Each message might belong to one of three groups: A, B, or C.
The receiving application has to process messages belonging to only one group and must also select messages by MQMD.MsgId. In addition, there are plans to add a department id as a searchable property. What is the BEST way of doing this?

• A. Use message properties to store property values and use MQGMO_BROWSE_FIRST withMQGMO_MATCH_MSG_ID to search for messages belonging to the right group and then getthe full message
• B. Use selector strings to receive the appropriate messages
• C. Store the property values at the beginning of the message body, useMQGMO_BROWSE_FIRST and MQGMO_ACCEPT_TRUNCATED_MESSAGE to search formessages belonging to the right group and then get the full message
• D. Use message properties to store property values and use MQGMO_BROWSE_FIRST tosearch for messages belonging to the right group and then get the full message
