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

1. 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) A trigger monitor is unable to start the triggered program
C) The destination queue is full when the program puts the message to the local queue
D) The program tries to put a message to an invalid local queue
E) The queue manager is quiescing when the program puts the message to the queue

2. Queue Managers QMA and QMB both have a cluster queue definition for Q1. A sending application resides on QMC, which is also part of the cluster. The messages being sent from QMC contain data from the same account that needs to be processed at the destination (Q1) in the same order that the messages were sent. Which one of the following is MOST LIKELY to enforce the sending order on the destination queue, assuming the message can be routed to the destination queue?

A) The sending application opens Q1 with MQOO_BIND_ON_OPEN and sends the messages forthe account
B) Q1 is defined with DEFBIND(OPEN) and the sending application opens Q1 and sends themessages for the account
C) The sending application specifies the destination Queue Manager and Queue name on theopen for Q1 and sends the messages for the account
D) The sending application sends the messages for the account within the same unit of work

3. Which of the following contains the best mix of items to utilize in a queue name?

A) Environment Identifier, Object Type, Application Identifier
B) Application Identifier, Function
C) Application Identifier, Environment Identifier, Location
D) Queue Purpose, Object Type, Function

4. 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) Some topologies cannot be implemented because queue managers can only be members ofone cluster.
B) Client applications connected to a queue manager cannot continue processing when itbecomes unavailable.
C) In the event of a server outage messages already queued will be delayed until the server canbe restarted.
D) Special considerations apply when software maintenance needs to be applied.

5. 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 selector strings to receive the appropriate messages
B) 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
C) 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
D) 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
