IBM WebSphere MQ V7.0, Solution Design Sample Questions:

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

2. A solution designer is evaluating distribution scenarios and wants to understand the circumstances where messages are not delivered as expected. Which of the following are reasons that a message is placed on the DLQ?

A) A sending message channel agent is unable to perform data conversion when required for the message
B) The program tries to put a message to an invalid local queue
C) The queue manager is quiescing when the program puts the message to the queue
D) The destination queue is full when the program puts the message to the local queue
E) A trigger monitor is unable to start the triggered program

3. A company utilizes virtualization technologies and frequently moves workloads between servers and data centers. A WebSphere MQ solution designer is attempting to plan the MQ naming standards, and wants to provide for the greatest level of architectural flexibility and portability. Which of the following is NOT a recommended best practice to meet these goals?

A) Use generic names for MQ objects inside applications to avoid hard-coding the actual names.
B) Use a configuration file for the application which contains the environment specific queuenames.
C) Use alias queues and/or model queues with the application configuration.
D) Use full uppercase for all objects and avoid forward slash (/) and percent (%) specialcharacters, to prevent portability issues.

4. Client applications are sending requests which are stored in a common queue. Each message might belong to one of three groups: A, B, or C.
The receiving application has to process messages belonging to only one group and must also select messages by MQMD.MsgId. In addition, there are plans to add a department id as a searchable property. What is the BEST way of doing this?

A) Use message properties to store property values and use MQGMO_BROWSE_FIRST tosearch for messages belonging to the right group and then get the full message
B) Store the property values at the beginning of the message body, useMQGMO_BROWSE_FIRST and MQGMO_ACCEPT_TRUNCATED_MESSAGE to search formessages belonging to the right group and then get the full message
C) Use message properties to store property values and use MQGMO_BROWSE_FIRST withMQGMO_MATCH_MSG_ID to search for messages belonging to the right group and then getthe full message
D) Use selector strings to receive the appropriate messages

5. An application has to set a unique ID (MQCHAR48) in each message. What is the best place to store this ID?

A) MQMD.UserIdentifier
B) Message Properties
C) MQMD.MsgId
D) MQMApplIdentityData
