IBM WebSphere MQ V7.0, Solution Design C9530-376 Prüfungsfragen mit Lösungen
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. The program tries to put a message to an invalid local queue
- B. A trigger monitor is unable to start the triggered program
- C. A sending message channel agent is unable to perform data conversion when required for the message
- D. The queue manager is quiescing when the program puts the message to the queue
- E. The destination queue is full when the program puts the message to the local queue
Antwort: B,C 🗳️
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. Special considerations apply when software maintenance needs to be applied.
- B. Some topologies cannot be implemented because queue managers can only be members ofone cluster.
- C. In the event of a server outage messages already queued will be delayed until the server canbe restarted.
- D. Client applications connected to a queue manager cannot continue processing when itbecomes unavailable.
Antwort: C 🗳️
A solution designer is looking to implement a highly available WebSphere MQ solution. In the event of a queue manager failure, there is a requirement for several backup queue managers to get and process the messages from the primary input queue that was being processed by the failed queue manager. Considering the advances in high availability options (e.g. HACMP, WebSphere MQ clustering), which of the following deployment options is most valid?
- A. z/OS, AIX, Windows, Red Hat Enterprise Linux
- B. z/OS, AIX
- C. z/OS
- D. z/OS, AIX, Windows
Antwort: C 🗳️
An application running on Unix is reading MQ messages that were created on z/OS and consist of multimedia content. A small percentage of the messages are large. The application should allocate a big buffer only when needed. The queue is opened with the MQOO_INPUT_EXCLUSIVE and the MQOO_BROWSE option. In addition to MQGMO_BROWSE_FIRST, which options should be used for getting messages?
- A. MQGMO_MSG_UNDER_CURSOR, MQGMO_CONVERT
- B. MQGMO_MSG_UNDER_CURSOR
- C. MQGMO_MSG_UNDER_CURSOR, MQGMO_LOCK, MQGMO_CONVERT
- D. MQGMO_MSG_UNDER_CURSOR, MQGMO_LOCK
Antwort: B 🗳️
A solution designer and the development team are discussing whether the "Read Ahead" feature of WebSphere MQ can improve performance for the application they are developing. Which of the following would be MOST able to benefit from this feature?
- A. Persistent or nonpersistent messages consumed by a client or a bindings program
- B. Nonpersistent messages consumed by a client or a bindings program
- C. Persistent or nonpersistent messages consumed by a client program
- D. Nonpersistent messages consumed by a client program.
Antwort: D 🗳️
