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• C. Store messages in separate queues for each region and use the expiration feature of themessaging system to delete outdated messages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

There is a requirement for a failover mechanism as part of an application to be deployed on Sun servers. The organization has standardized on Veritas Cluster Server to manage failover on the machines. What should be considered when designing the solution?

• A. Implement shared queues for true high-availability.
• B. The application needs to be designed to handle concurrent database transactions from each ofthe Veritas nodes.
• C. Utilize WebSphere MQ clustering to send the traffic to the failover server.
• D. State data needed by the application for recovery after a failure needs to be on shared disks.

The use of Shared Queues on z/OS provides which of the following high availability benefits that
are not available on distributed platforms?

• A. A platform-based failover capability to provide access to queue data for processing.
• B. In the event of a queue manager failure, the ability of one of its peers to provide uninterruptedservice to the queues that the failed queue manager had been processing.
• C. Workload balancing to allow for multiple MQ Enabled applications to process messages in adual production lane configuration.
• D. The ability to have another queue manager process messages in the event a primary queuemanager fails.

A WebSphere MQ client application is sending messages to a central server which will later be processed in batch. Given that all information is stored only in a central location, what is the best way of designing such communication? The application:

• A. puts messages to a server queue, and no acknowledgement from the central application isrequired.
• B. sends updates and the server should send acknowledgement messages. The applicationshould wait for them in the same thread that sent the update messages.
• C. publishes the messages to a topic defined by the server application.
• D. sends updates and the server should send acknowledgement messages. The applicationshould wait for them in a separate thread.

An application is using the WebSphere MQ V7.0 MQI to read a message that has been created using JMS on a WebSphere MQ V6 queue manager. How can the developer access the JMS user defined properties?

• A. Use the MQGMO_PROPERTIES_IN_HANDLE option and provide the MsgHandle when getting messages from a queue.
• B. Read the whole message and convert the MQRFH2 header using the MQMHBUF function, because the message has been created using a previous version of the JMS API.
• C. Ask the administrator to set PROPCTL to COMPAT on the receiving channel, so the MQRFH2 header will be transformed into message properties.
• D. Read the whole message and parse the MQRFH2 header, because the message has been created using a previous version of the JMS API.
