QUESTION 31

In a centralized queuing environment, a batch program is processing a file, and putting the transactions onto a queue for processing within syncpoint control. The batch program is experiencing issues, and a support resource is contacted to investigate. Which of the following is NOT a likely cause of the issues?

 

A.

The application issues commits infrequently

B.

The MAXDEPTH parameter is causing restrictions on the queue.

C.

Because the real-time non-persistent messages are mixed in with the batch transactions on the queue, the queue is filling up.

D.

Because the real-time non-persistent messages are mixed in with the batch transactions on the queue, the circular logs are filling up and writing over each other.

 

Correct Answer: D

 

 

QUESTION 32

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.

Define the incoming file as an alias to the Pricing System queue Q1.

B.

Use RFHUTIL to move the data from the file to the Pricing System queue Q1.

C.

Use the File Transfer Application that comes with WebSphere MQ to read the records from the file and send them to the Pricing System queue Q1.

D.

Write a program that reads through the file, taking each record from the file and putting it as a message on the input queue to the Pricing System queue Q1.

 

Correct Answer: D

 

 

QUESTION 33

While trying to get messages from its input queue a program is receiving notification that no messages are available. However, the queue depth indicates that there are messages on the queue. Which of the following are possible explanations for this?

 

A.

The program lost the authority to get messages from this queue as a result of an administrator action.

B.

Messages have been put to the queue by another program, but have not been committed yet.

C.

The program is failing to specify a MsgId or CorrelId, so no messages are being are being returned when it issues an MQGET.

D.

The program is specifying a particular MsgId or CorrelId that does not match any messages currently on the queue.

E.

The queue has been set to et inhibited by an administrator. The queue has been set to yet Inhibited by an administrator.

 

Correct Answer: BD

 

 

QUESTION 34

An application is required to retrieve rows from a relational database table and send them across WebSphere MQ to a remote queue manager, where a receiving application consumes them. After a successful MQPUT of a message, the corresponding row is to be deleted from the database. It is intended to run this application using the free WebSphere MQ Client. The delivery of each message is to be guaranteed. Which of the following is true about this implementation?

 

A.

It cannot be done using the free WebSphere MQ Client; the Extended Transactional Client is required, since two phase commits are needed for this solution.

B.

It cannot be done using the free WebSphere MQ Client; a local queue manager is required to support the guaranteed delivery of the messages.

C.

This solution can be implemented using the free WebSphere MQ Client, provided that the receiving application can recognize and handle repeated delivery of the same message.

D.

This solution cannot be implemented using the free WebSphere MQ Client; persistent messaging is not supported by the free WebSphere MQ Client.

 

Correct Answer: C

 

 

QUESTION 35

An application is experiencing issues when processing large volumes of nonpersistent messages. Which of the following is a likely cause of the issue?

 

A.

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

B.

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

C.

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

D.

The application is processing in syncpoint, and has not performed a commit recently.

 

Correct Answer: D

 

 

QUESTION 36

A company needs to send state information to many recipients. The recipients will change over time, and they only want to receive the latest data if and when they need it. Which of the following most closely satisfies the requirements and is most efficient for the subscriber?

 

A.

Distribution lists

B.

Durable subscriptions

C.

Nondurable subscriptions

D.

Retained publications and use of MQSUBRQ

 

Correct Answer: D

QUESTION 37

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

 

A.

Make messages nonpersistent if they do not need to be recoverable.

B.

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.

C.

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).

D.

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).

 

Correct Answer: C

 

 

QUESTION 38

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.

Assured delivery

B.

Ability to provide access to legacy applications

C.

Integration with, and reuse of, existing WebSphere MQ infrastructure

D.

WebSphere MQ clustering for load balancing and enhanced reliability and availability

 

Correct Answer: B

 

 

QUESTION 39

A solution designer is looking to implement a robust failover mechanism as part of a solution, and has decided on utilizing HACMP on AIX. What must be considered when designing the application?

 

A.

Application log and state information should be stored on shared disk.

B.

WebSphere MQ clustering should be utilized to cluster the queues between the two server nodes.

C.

The architecture should be designed to process duplicate transactions in cases where a failover needs to occur.

D.

The application needs to be designed to run on multiple servers, and needs to handle heartbeats between application instances.

 

Correct Answer: A

 

 

QUESTION 40

A company would like to expand their services to accept incoming orders from external partners. Some of the external partners already use WebSphere MQ, and the others could install WebSphere MQ or run a WebSphere MQ client. The company is concerned about significantly increasing the number of channels into their queue manager as a result of connecting to so many new external partners. Which of the following could reduce this concern?

 

A.

Use SSL to encrypt the channels

B.

Use WebSphere MQ Cluster channels to limit the interconnectivity

C.

Use shared conversations to reduce the number of connections to the queue manager

D.

Use WebSphere MQ Internet Passthru to act as a channel concentrator for the queue manager

E.

Use DataPower XI50 to handle some of the external traffic and forward the messages to the queue manager

 

Correct Answer: DE
