IBM WebSphere MQ V7.0, Solution Design Sample Questions:

1. A designer is asked to explain the scope of message encryption provided by the SSL support in WebSphere MQ. Which of the following is the most accurate?

A) Messages are encrypted when they are put on the transmission queue and decrypted by thereceiving channel agent
B) Messages are encrypted from the time they are put by the application, up to when they areretrieved by the receiving application program's MQGET call.
C) The time when messages are encrypted and decrypted is variable, and is controlled by bothQMGR and CHANNEL attributes.
D) Messages are encrypted by the sending channel agent and decrypted by the receiving channelagent

2. An application creates documents in PDF format, which are subsequently transmitted via WebSphere MQ to a number of other servers in the network. Each server runs its own queue manager. The documents received by some servers are consistently corrupted, whereas on other servers the documents are intact. Other message traffic seems unaffected. What is the most likely source of this problem?

A) The affected servers run different CCSIDs from the servers creating the documents and the message descriptor specifies MQMFormat as QSTR? causing message conversion.?QSTR? causing message conversion.
B) The network connection to the affected servers is unreliable and a message retry exit was not specified on the sending channel agent.
C) Incompatible message compression parameters are configured on the sending and receiving channel agents.
D) The environment variable MQCCSID specifies an incorrect value on the affected servers.

3. Which of the following best explains under which circumstances synchronous put can be useful for a client application?Which of the following best explains under which circumstances ?synchronous put?can be useful for a client application?

A) Asynchronous put cannot be used for messages put under syncpoint, but is a good option touse otherwise.
B) The designer wants to improve the performance of puts, and the application needs immediateconfirmation that the put was successful.
C) The designer wants to improve the performance of puts, and the application does not needimmediate confirmation that the put was successful.
D) If all the messages put by the application are nonpersistent, as they are required to be forasynchronous put, it would be appropriate to use this option to improve performance.

4. 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) Stage the migration, but migrate all the queue managers on a particular operating system atthe same time.
C) Migrate all the queue managers in the cluster at the same time to make sure there are noincompatibilities between versions.
D) At a minimum, migrate the full repositories at the same time, to avoid incompatibilities in thedefinitions that they store.

5. A server application needs to record a unique id from the user who has created a request message in the Windows environment. Which MQMD field contains this information?

A) ApplIdentityData
B) UserIdentifier
C) ApplOriginData
D) AccountingToken
