Question 1

A WebSphere MQ client application is sending messages to a central server which will later be processed in batch. Given that all information is stored only in a central location, what is the best way of designing such communication? The application:

A. puts messages to a server queue, and no acknowledgement from the central application isrequired. B. sends updates and the server should send acknowledgement messages. The applicationshould wait for them in the same thread that sent the update messages. C. publishes the messages to a topic defined by the server application. D. sends updates and the server should send acknowledgement messages. The applicationshould wait for them in a separate thread.

Question 2

An application is being designed which will send updates about customers to different applications. Given the sensitive nature of the data, the sending application needs to manage which applications receive the datA. Which of the following is the best solution to ensure this?

A. Apply the publish-subscribe paradigm (one-to-many). B. Each application should have its own queue on which it will listen for updates C. All receiving applications should listen on the same queue and the sending application shouldsend separate copies of the message with attributes which allow the receiving applications tosearch the queue for their own copies. D. All applications should listen on the same queue and after processing the message shouldupdate its header so the last application process can remove it from the queue

Question 3

A business requirement is brought forward for a back end server that is to send replies to requests sourced on the web and on internal application servers. The back end application will perform database lookups and formatting operations that are deemed trivial. Message sizes, traffic volumes and estimated annual growth rates are provided. The application designer is asked to provide a sizing estimate for a server that will be able to provide the response times stipulated in the SLA. Which is the fastest way to arrive at a reasonable estimate of the required server size?

A. Meaningful performance measurements can only be done once the application developmenthas progressed to the point where the actual code can be benchmarked. B. Consult the Performance Reports from the WebSphere MQ SupportPac website forcomparable measurements and extrapolate to the specified requirements. C. Create a suitable test program and test clients and perform a series of benchmarks on anavailable server. D. Collect performance statistics from other WebSphere MQ based applications and extrapolatethe findings to your requirements.

Question 4

A client application is subscribing to as many as five different topics (no wildcards are possible). Given that the number of client applications may vary and subscriptions are not durable, what is the best option for creating a subscription?

A. Create a temporary dynamic queue and call MQSUB for each topic. B. Use MQSUB with the MQSO_MANAGED option and the list of topic names separated bycommas and stored in the ObjectString field of the MQSD structure. C. Use MQSUB with the MQSO_MANAGED option for the first topic and subsequent calls withMQSO_ALTER for other topics. D. Create a temporary dynamic queue and use MQSUB with the list of topic names separated bycommas and stored in the ObjectString field of the MQSD structure.

Question 5

An organization has a widely distributed online environment, where applications are connected via WebSphere MQ messaging. A business requirement is brought forward that the delivery of certain persistent mission critical datagram messages needs to be recorded in a central location. The delivery information must not be lost. The mechanism used must not be dependent on cooperation of the receiving applications. Which of the following designs will meet these requirements?

A. The sending application will put a copy of each message on a central queue reserved for thispurpose, including the completion code and reason code of the original request. B. In the MQMD of the messages in question, COD and EXCEPTION reports will be requested;the resulting report messages will be delivered to the SYSTEM.ADMIN.REPORT.QUEUE onthe receiving queue manager. C. In the MQMD of the messages in question, COD and EXCEPTION reports will be requested;the Reply-to queue fields point at a queue on a central queue manager reserved for thispurpose. D. In the MQMD of the messages in question, PAN, NAN and EXCEPTION reports will berequested; the Reply-to queue fields point at a queue on a central queue manager reservedfor this purpose.

Question 6

A company is porting a solution written in C to i5/OS (successor to OS/400) that will send orders to the Order Processing system, which is a WebSphere MQ application on z/OS. Which of the following configurations for the new solution on i5/OS provides the function needed for this scenario? The solution on i5/OS would run:

A. as a standalone application, accessing a WebSphere MQ-enabled adapter on the mainframeto access the Order Processing system. B. only as a client, using the WebSphere MQ client on i5/OS to access the Order Processingsystem. C. only as a server, using the WebSphere MQ server on i5/OS to access the Order Processingsystem. D. as a client or full server, using either the WebSphere MQ client or a full WebSphere MQ serveron i5/OS to access the Order Processing system.

Question 7

A suite of server applications is to be designed to support the graceful shutdown capabilities of WebSphere MQ implemented via the ail ifA suite of server applications is to be designed to support the graceful shutdown capabilities of WebSphere MQ implemented via the mail if quiescing feature. Which of the following best describes the use of this feature?

A. Applications that have this feature activated can request an extra grace period of a configurable length that will allow them to complete critical processing before the queue manager will disconnect them. B. Using FAIL_IF_QUIESCING options where valid with MQI calls, an application can finalize MQ processing, avoiding loss of data, before the queue manager is shut down. C. Applications using this feature will be informed of the queue manager quiescing via a completion code of MQCC_FAILED and a reason code of MQRC_Q_MGR_QUIESCING (or MQRC_CONNECTION_QUIESCING) and will be disconnected automatically. Applications are expected to periodically attempt reconnection. D. When a queue manager is configured with the FAIL_IF_QUIESCING option and is being shut down, it will reject all MQI calls with a completion code of MQCC_FAILED and a reason code of MQRC_Q_MGR_QUIESCING (or MQRC_CONNECTION_QUIESCING) in order to assure fast and reliable termination.

Question 8

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. 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. B. 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. 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. 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.

Question 9

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 can be implemented using the free WebSphere MQ Client, provided that the receiving application can recognize and handle repeated delivery of the same message. B. This solution cannot be implemented using the free WebSphere MQ Client; persistent messaging is not supported by the free WebSphere MQ Client. C. 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. 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.
