IBM C9530-376 valid exam dumps : IBM WebSphere MQ V7.0, Solution Design

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. Ability to provide access to legacy applications
• C. Assured delivery
• D. WebSphere MQ clustering for load balancing and enhanced reliability and availability

Which of the following should generally be avoided if an application is being designed for optimal efficiency?

• A. Code programs to open and close queues, or connect and disconnect from the queue manager only once, if the queues or connection will be used again.
• B. Make messages nonpersistent if they do not need to be recoverable.
• C. Group a batch of messages within a unit of work where appropriate, so that they can be committed all at once (e.g., get and put messages under syncpoint and commit them in groups of 10, rather than committing them individually).
• D. Bundle the data to be transmitted into as few messages as possible (e.g., rather than sending a hundred 1MB messages, send one 100MB message).

A solution designer and the development team are discussing whether the "Read Ahead" feature of WebSphere MQ can improve performance for the application they are developing. Which of the following would be MOST able to benefit from this feature?

• A. Persistent or nonpersistent messages consumed by a client program
• B. Nonpersistent messages consumed by a client or a bindings program
• C. Nonpersistent messages consumed by a client program.
• D. Persistent or nonpersistent messages consumed by a client or a bindings program

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

What is a particular advantage of designing a publish/subscribe application to use a managed subscription, when the subscription type is non-durable?

• A. The temporary dynamic queue used for the subscription will not be deleted by the queuemanager until the current depth of the queue is zero, and the subscribing applicationconnection is closed.and the subscribing application? connection is closed.
• B. The temporary dynamic queue used for the subscription will be deleted, along with anymessages on it, when the subscribing applicationThe temporary dynamic queue used for thesubscription will be deleted, along with any messages on it, when the subscribing application'connection is closed. The temporary dynamic queue used for the subscription will not bedeleted by the queue manager until the current depth of the queue is zero.
• C. Any messages for this subscription will be managed by the queue manager, so they can beavailable if there are any subsequent subscribers.
