An application is being designed which will send updates about customers to different applications. Given the sensitive nature of the data, the sending application needs to manage which applications receive the datA. Which of the following is the best solution to ensure this?

Apply the publish-subscribe paradigm (one-to-many). ✘ Each application should have its own queue on which it will listen for updates ✘ All applications should listen on the same queue and after processing the message shouldupdate its headerso the last application process can remove it from the queue ✘ All receiving applications should listen on the same queue and the sending application shouldsend separatecopies of the message with attributes which allow the receiving applications tosearch the queue for their own copies. ✔

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

Any messages for this subscription will be managed by the queue manager, so they can beavailable if there
are any subsequent subscribers. ✘ 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. ✘ The temporary dynamic queue used for the subscription will not be deleted by the queue manager until thecurrent depth of the queue is zero, and the subscribing applicationconnection is closed.and the subscribing
application connection is closed. ✘

A solution designer is using the DEFPSIST attribute on the queue definition to determine message persistence. Queue Manager QMA has a QREMOTE queue defined that points to a QALIAS definition on Queue Manager QMB, which in turn names a QLOCAL queue as its TARGET. If an application puts a message to the QREMOTE on Queue Manager QMA, which of the queue definitions will control the persistence of the message?

The QREMOTE on QMA ✘ The transmission queue on QMA ✘ The QLOCAL on QMB ✘ All four of the queue definitions (QREMOTE, Transmission queue, QALIAS, QLOCAL) ✔

Which of the following is NOT a generally recommended best practice for naming conventions?

Queue and channel names should be limited to less than 24 characters because of platformportability
concerns. ✘ When possible, avoid forward slash (/) and percent (%) special characters because they cancause cross-platform difficulties. ✘ Queues should not have the word QUEUE in their name, nor should they have the topology inthe name(local, remote, alias, etc). ✘ Use full uppercase for WebSphere MQ objects, including the queue manager, to preventportability issues inheterogeneous environments. ✔

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?

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

A solution designer has requested that several queues on a z/OS queue manager be defined with index type set to message ID, i.e., INDXTYPE(MSGID). Why would a designer use this setting?

It creates a permanent index of MSGIDs that are currently in use for this queue. ✘ It allows MQGET commands to have significantly improved performance when gettingmessages bymessage ID. ✘ It ensures that any new MSGIDs are unique as well as making the retrieval of messagesbased on messageID more efficient. ✘ The queue manager will keep an index of MSGIDs that have already been used to make surethat the message ID is unique when a new message is put. ✔
