問題1

While planning for a new application, the performance of nonpersistent messages sent through message channels is being discussed. If the messages will be sent through channels with NPMSPEED(FAST), which of the following BEST describes the effect this will have?

A. The channel will send nonpersistent messages with a higher priority than persistent ones.

B. Nonpersistent message delivery is as reliable as if NPMSPEED(NORMAL) had been used,and nonpersistent messages can be delivered by the receiver channel more quickly.

C. The queue manager will attempt to deliver the nonpersistent messages more quickly, but theiravailability on the receiving queue manager might be delayed while waiting for the channel tocommit them.

D. Nonpersistent messages can be made available by the receiver channel more quickly, but theycan be discarded if they cannot be delivered.

正確答案: D

B. The BATCHSIZE parameter on the queuemanager was left at the default setting.

C. The WebSphere MQ circular logs are not large enough to handle all of the transactions.

D. The WebSphere MQ linear logs are not large enough to handle all of the transactions.

正確答案: A

正確答案: A,B

問題6

When designing test scenarios for pre-production testing, it is good practice to closely match the production environment in its metrics in order to produce realistic runtime behavior. In this context, which of the following statements about WebSphere MQ logging capability BEST describes the role that logging considerationsIn this context, which of the following statements about WebSphere MQ' logging capability BEST describes the role that logging considerations play in quality assurance or user acceptance testing?

A. Since changing the log file sizes requires a rebuild of the queue manager it is recommended tocreate the QA queue managers with as large a log space allocation as possible.

B. It is important to run with exactly the same logging style and log file sizes as in production inorder to properly test the application behaviorIt is important to run with exactly the samelogging style and log file sizes as in production in order to properly test the application'sBehavior regarding the use of log space.

C. As long as the same logging method (circular or linear) is used as in the productionenvironment, there will be no problems; the logging algorithms can handle unexpected loadsgracefully.

D. Even with identical logging parameters it is difficult to simulate the exact load on the loggingsystem, since the actual requirements are accumulated across all concurrently runningapplications, including channels.

正確答案: D

問題7

A company has an existing point to point application written in C that distributes delivery status to queue Q1. They want to change the distribution to publish/subscribe so that other applications can subscribe to the delivery status information. Which of the following ways of changing to WebSphere MQ publish/subscribe will work with the least recoding?

A. Change the sending application program to use WebSphere MQ publish/subscribe commandsin RFH2 headers instead of the point to point API

B. Set up a queue alias for Q1 that is an alias for a subscription topic

C. Change the sending application program to use the WebSphere MQ publish/subscribe APIinstead of point to point

D. Run WebSphere MQ in PSMODE=COMPAT

正確答案: B

問題8

A solution developer is writing a C language application on a UNIX platform. There is a requirement for the transactions to be processed within syncpoint control. What is the MINIMUM required MQ component on the application platform to achieve this functionality?

A. WebSphere MQ Client Installation

B. WebSphere MQ Extended Transactional Client Installation

C. WebSphere MQ Server Installation with the XA capabilities configured

D. WebSphere MQ Server Installation

正確答案: A

問題9

A customer has an environment where applications are frequently redeployed to different servers
to react to changing capacity needs. Which of the following will provide the best support for the affected applications to be moved?

A. Affected applications will be linked with the MQ Client interface and will maintain connectionsto all affected queue managers simultaneously; they will then find the respective queues byquerying the queue managers.

B. Affected applications will read configuration files from their local file system that are updatedby administrators to reflect the new locations of destination queues; they then have todynamically build the appropriate queue names before opening the queues.

C. Affected applications will first connect to a central queue manager via the WMQ client interfacewhere they can find configuration information in a special queue; they then open theirrespective application queues accordingly.

D. Affected applications will connect to default queue managers and use generic, locationindependent queue names only; a set of alias and remote queue definitions are used in thequeue managers to connect applications to where the real queues are at any point in time.Input queues need to move with the owning applications.

正確答案: D

問題10

Business owners want to allow an existing application to be easily portable to any of four Linux servers in their data center. For this they want the four queue managers on these servers to be changed to have the same name. What must be the response of the WebSphere MQ Solution Designer?

A. It is possible to define queue managers with identical names in a network, but it is not recommended.

B. Queue managers cannot be renamed, so this can only be done by recreating the queue managers. Beyond that, there is no problem.

C. There is no problem.

D. It cannot be done. All interconnected queue managers must have unique names.
