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 the WebSphere MQ publish/subscribe APIinstead of point to point
• B.Run WebSphere MQ in PSMODE=COMPAT
• C.Change the sending application program to use WebSphere MQ publish/subscribe commandsin RFH2 headers instead of the point to point API
• D.Set up a queue alias for Q1 that is an alias for a subscription topic

An organization uses WebSphere MQ V6 client interfaces extensively for non-critical processing. The line of business announces that an increase in transaction rates will be required soon, when a new set of clients will need to be serviced. The application suite has been performing up to expectations so far, but the new requirements will be problematic in the current environment. Which of the following new features of WebSphere MQ V7.0 can potentially be used to improve throughput for the above scenario?

• A.No significant throughput improvements can be achieved with WebSphere MQ V7.0.
• B.WebSphere MQ V7.0 Client channels can be configured to compress message data and thus save on network transmission time.
• C.WebSphere MQ V7.0 Client channels are significantly faster than their V6 counterparts by default, so the solution designer does not need to consider any functionality changes or examine performance impacts with the new traffic.
• D.WebSphere MQ V7.0 Clients can be configured to pool connections, to send messages without waiting for acknowledgement from the queue manager, and to asynchronously receive and cache incoming messages, before they have been requested by the receiving applications.

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 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.
• B.The channel will send nonpersistent messages with a higher priority than persistent ones.
• C.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.
• D.Nonpersistent messages can be made available by the receiver channel more quickly, but theycan be discarded if they cannot be delivered.

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.This solution cannot be implemented using the free WebSphere MQ Client; persistent messaging is not supported by the free WebSphere MQ Client.
• B.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.
• 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.It cannot be done using the free WebSphere MQ Client; a local queue manager is required to support the guaranteed delivery of the messages.

A solution designer is considering different API options for a new WebSphere MQ application.
Only IBM supported WebSphere MQ programming options should be considered. Which one of the following is not supported by IBM?

• A.WebSphere MQ classes for .NET
• B.JMS
• C.Perl
• D.XMS
