1. 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 is specifying a particular MsgId or CorrelId that does not match any messagescurrently on the queue.
B) Messages have been put to the queue by another program, but have not been committed yet.
C) The program lost the authority to get messages from this queue as a result of an administratoraction.
D) The program is failing to specify a MsgId or CorrelId, so no messages are being are beingreturned when it issues an MQGET.
E) The queue has been set to et inhibitedby an administrator.The queue has been set toyetInhibitedby an administrator.

2. A bus company is implementing a solution which will display in real-time the arrival information of the next bus on the bus stop sign. Each bus is sending information about its position at regular intervals. What is the best way of implementing this solution given that there is limited bandwidth for communication? The bus stop sign:

A) sends a message with a request every few minutes to a central system in order to query busposition. All replies are compressed.
B) replicates its own database every few minutes with a database stored on a central system
C) queries a central system for bus position using SOAP over HTTP
D) subscribes to messages published by the bus

3. A manufacturing company is looking to provide its customers an online version of its order maintenance application. Customers will be able to check status, update the order, or delete the order. The existing solution is currently WebSphere MQ based, and the online interface will have strict performance requirements. If the customer updates or deletes an order, the message cannot be lost. Which one of the following solutions will BEST meet the requirements stated?

A) Ensure the queue data and logs are located together on the fastest disk possible
B) Port the existing application to z/OS which has the highest performance and availability qualities of service
C) Design the query and modify operations to use nonpersistent and persistent messages respectively, and utilize two phase commit only where Necessary
D) Alter the channel to set NPMSPEED(FAST), and send the messages down multiple channels.

4. A company is using WebSphere MQ V7 publish/subscribe to publish status information about an application on the topic string ustomer/status?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 navailable? TheA 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 V7.0 with WebSphere Message Broker and the WebSphere MQ Explorer Publish/Subscribe plug-in SupportPac
B) WebSphere MQ V7.0 with WebSphere Message Broker
C) WebSphere MQ V7.0
D) WebSphere MQ V7.0 with the WebSphere MQ Explorer Publish/Subscribe plug-in SupportPac

5. 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) 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.
D) 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.
