QUESTION 11

A company needs to improve availability of client connections for its distributed applications. Which one of the following is a true statement about a new option or capability of WebSphere MQ V8.0 that could improve availability?

 

A.

TCP/IP client connections are now always full duplex, and full duplex can support earlier detection of network failures

B.

Client connections on the same server can share an instance of a channel connection, reducing the number of sockets required

C.

The new MQSTAT verb can be used to determine the health of a Queue Manager, leading to quicker detection and recovery from an outage

D.

There is a new maximum instance channel limit that can catch a client application instance that is attempting to use an excessive number of channel connections

 

Correct Answer: D

 

 

QUESTION 12

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.

Run WebSphere MQ in PSMODE=COMPAT

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 API instead of point to point

D.

Change the sending application program to use WebSphere MQ publish/subscribe commands in RFH2 headers instead of the point to point API

 

Correct Answer: B

 

 

QUESTION 13

A company is using WebSphere MQ V7 publish/subscribe to publish status information about an application on the topic string ustomer/status. A new MQI application wants to subscribe to the status information, but is only interested in the information when the status is available. The solution designer is evaluating ways to design the solution so that the application only receives a subscription when the status is available solution designer is evaluating ways to design the solution so that the application only receives a subscription when the status is available. The company does not mind writing additional code as long as it does not impact existing subscribers, but they do not want to change the topic. Which set of product(s) can provide the needed publish/subscribe function using the least components?

 

A.

WebSphere MQ V8.0

B.

WebSphere MQ V8.0 with WebSphere Message Broker

C.

WebSphere MQ V8.0 with the WebSphere MQ Explorer Publish/Subscribe plug-in SupportPac

D.

WebSphere MQ V8.0 with WebSphere Message Broker and the WebSphere MQ Explorer Publish/Subscribe plug-in SupportPac

 

Correct Answer: A

 

 

 

QUESTION 14

An application needs to display the last published message every five minutes. What is the best way of doing this?

 

A.

Use MQSUB with SubExpiry set to 300.

B.

Use MQSUB with MQSO_PUBLICATIONS_ON_REQUEST option and SubExpiry set to 300.

C.

Use MQSUB with MQSO_PUBLICATIONS_ON_REQUEST and call MQSUBRQ every five minutes.

D.

Use MQSUB with MQSO_NEW_PUBLICATIONS_ONLY and call MQSUBRQ every five minutes.

 

Correct Answer: C

 

 

QUESTION 15

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

 

A.

The designer wants to improve the performance of puts, and the application needs immediate confirmation that the put was successful.

B.

The designer wants to improve the performance of puts, and the application does not need immediate confirmation that the put was successful.

C.

Asynchronous put cannot be used for messages put under syncpoint, but is a good option to use otherwise.

D.

If all the messages put by the application are nonpersistent, as they are required to be for asynchronous put, it would be appropriate to use this option to improve performance.

 

Correct Answer: B

 

 

QUESTION 16

WebSphere MQ clusters are sometimes positioned to provide high availability for backend services. For many use cases this works well;
but which concern may make this solution unacceptable in some cases?

 

A.

Special considerations apply when software maintenance needs to be applied.

B.

Client applications connected to a queue manager cannot continue processing when it becomes unavailable.

C.

In the event of a server outage messages already queued will be delayed until the server can be restarted.

D.

Some topologies cannot be implemented because queue managers can only be members of one cluster.

 

Correct Answer: C

 

 

QUESTION 17

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

 

A.

Any messages for this subscription will be managed by the queue manager, so they can be available if there are any subsequent subscribers.

B.

The temporary dynamic queue used for the subscription will be deleted, along with any messages on it, when the subscribing applicationThe temporary dynamic queue used for the subscription 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 be deleted by the queue manager until the current depth of the queue is zero.

C.

The temporary dynamic queue used for the subscription will not be deleted by the queue manager until the current depth of the queue is zero, and the subscribing application connection is closed.and the subscribing application? connection is closed.

 

Correct Answer: B

 

 

QUESTION 18

An organization has a widely distributed online environment, where applications are connected via WebSphere MQ messaging. A business requirement is brought forward that certain mission critical applications record audit trail data which is to be collected in a central location. No information can be lost. A central data warehouse must be loaded daily with this information as soon as possible after end of business. Which of the following proposed solutions is best in terms of the requirement, reliability and overall performance? The audit trail data is:

 

A.

written to a file on the local file system and transmitted to the central audit trail server via reliable file transfer over WebSphere MQ.

B.

sent as a persistent WebSphere MQ message and forwarded to the queue manager of the central server asynchronously.

C.

inserted into a central database table via a remote access database client under control of the local WebSphere MQ transaction.

D.

inserted into a local database table under two phase commit using WebSphere MQ as the transaction manager and a bulk update is performed at end of day.

 

Correct Answer: B

B.

The destination queue is full when the program puts the message to the local queue

C.

The queue manager is quiescing when the program puts the message to the queue

D.
