質問 1：
A WebSphere MQ application has been designed to use triggering with TRIGTYPE(FIRST). Which of the following is recommended for the program that has been started to process the triggered queue?
A. Do MQGET without the wait option so that the application program does not keep the queueopen unnecessarily.
B. MQGET only the number of messages the program is expected to process, so additionalcopies of the program will be triggered to process subsequent messages.
C. Do not allow the program to end unless it MQGETs at least one message.
D. Do MQGET with the wait option because the trigger message can be put, causing theapplication program to start, before all messages to be processed have been committed.
正解：D

質問 3：
An organization has a widely distributed online environment, where applications are connected via WebSphere MQ messaging. A business requirement is brought forward that the delivery of certain persistent mission critical datagram messages needs to be recorded in a central location. The delivery information must not be lost. The mechanism used must not be dependent on cooperation of the receiving applications. Which of the following designs will meet these requirements?
A. In the MQMD of the messages in question, COD and EXCEPTION reports will be requested;the resulting report messages will be delivered to the SYSTEM.ADMIN.REPORT.QUEUE onthe receiving queue manager.
B. In the MQMD of the messages in question, COD and EXCEPTION reports will be requested;the Reply-to queue fields point at a queue on a central queue manager reserved for thispurpose.
C. The sending application will put a copy of each message on a central queue reserved for thispurpose, including the completion code and reason code of the original request.
D. In the MQMD of the messages in question, PAN, NAN and EXCEPTION reports will berequested; the Reply-to queue fields point at a queue on a central queue manager reservedfor this purpose.
正解：B

質問 4：

B. The most detail about the cause of the problem should be found in the exception at the top ofthe list.
C. The WebSphere MQ Reason and Completion code will not be reported in the exceptions.
D. The order in which the exception messages are shown is random and cannot be relied on.
正解：A

質問 5：
An application is replying to a request message, which has properties associated with it. What is the preferred way of creating a reply message?
A. Create a new MQMD for the reply message and copy the MsgId from the request MQMD structure to the CorrelId field of the reply MQM
B. Use action indicator in MQPMO, provide new MQMD for reply message and use MQPMO_NEW_MSG_ID in the MQPUT options.
C. Reuse the MQMD and honor the report options set in the request message.
D. Use action indicator in MQPMO and MQPMO_MD_FOR_OUTPUT_ONLY in the MQPUT options.
正解：D

質問 6：
A WebSphere MQ for AIX application currently accepts an individual price change from an online user via local queue Q1. The company would like to start receiving price changes via a new input file on AIX. They are evaluating different approaches to transfer the data from the file to the pricing system queue Q1. Which of the following approaches is most appropriate for these requirements?
A. Write a program that reads through the file, taking each record from the file and putting it as amessage on the input queue to the Pricing System queue Q1.
B. Use RFHUTIL to move the data from the file to the Pricing System queue Q1.
C. Define the incoming file as an alias to the Pricing System queue Q1.
D. Use the File Transfer Application that comes with WebSphere MQ to read the records from thefile and send them to the Pricing System queue Q1.
正解：A

質問 7：
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. Perform a staged migration, in which queue managers are migrated one at a time.
C. Stage the migration, but migrate all the queue managers on a particular operating system atthe same time.
D. At a minimum, migrate the full repositories at the same time, to avoid incompatibilities in thedefinitions that they store.
正解：B
