IBM C2180-376 問題集

質問 1：
An application receives messages created on Windows workstations and, after doing transformations, forwards them to a target system running on z/OS. There is a requirement for passing the original username, but information about the date and time associated with the message should be set by the forwarding application. What is the best way of doing this?
A. Use MQPMO_DEFAULT_CONTEXT on Windows and MQPMO_PASS_IDENTITY_CONTEXT in forwarding application
B. Use MQPMO_DEFAULT_CONTEXT on Windows and MQPMO_PASS_ALL_CONTEXT in the forwarding application
C. Use MQPMO_SET_IDENTITY_CONTEXT on Windows and MQPMO_PASS_IDENTITY_CONTEXT in the forwarding application
D. Use MQPMO_SET_IDENTITY_CONTEXT on Windows and MQPMO_PASS_ALL_CONTEXT in the forwarding application
正解：A

質問 2：
There is a requirement for a failover mechanism as part of an application to be deployed on Sun servers. The organization has standardized on Veritas Cluster Server to manage failover on the machines. What should be considered when designing the solution?
A. The application needs to be designed to handle concurrent database transactions from each ofthe Veritas nodes.
B. Utilize WebSphere MQ clustering to send the traffic to the failover server.
C. Implement shared queues for true high-availability.
D. State data needed by the application for recovery after a failure needs to be on shared disks.
正解：D

質問 3：
A company would like to expand their services to accept incoming orders from external partners.
Some of the external partners already use WebSphere MQ, and the others could install WebSphere MQ or run a WebSphere MQ client. The company is concerned about significantly increasing the number of channels into their queue manager as a result of connecting to so many new external partners. Which of the following could reduce this concern?
A. Use DataPower XI50 to handle some of the external traffic and forward the messages to thequeue manager
B. Use shared conversations to reduce the number of connections to the queue manager
C. Use SSL to encrypt the channels
D. Use WebSphere MQ Internet Passthru to act as a channel concentrator for the queuemanager
E. Use WebSphere MQ Cluster channels to limit the interconnectivity
正解：A,D

質問 4：
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 queue manager is quiescing when the program puts the message to the queue
B. The program tries to put a message to an invalid local queue
C. A trigger monitor is unable to start the triggered program
D. The destination queue is full when the program puts the message to the local queue
E. A sending message channel agent is unable to perform data conversion when required for the message
正解：C,E

質問 5：
A server application will be written to respond to request messages from multiple independent sources. Each request message will have a unique reply-to-queue. Which MQI calls should be used in addition to MQCONN and MQDISC?
A. MQGET, MQPUT1
B. MQOPEN, MQCLOSE, MQGET, MQPUT
C. MQOPEN, MQCLOSE, MQGET, MQPUT1
D. MQGET, MQPUT
正解：C

質問 6：
A solution developer needs to promote newly developed applications from the development environment through the user acceptance test environment and into the production environment. Which of the following will best avoid issues with naming conventions for application-owned permanent queues?
A. A standard should be implemented by which all queue names will be prefixed with the queue manager name, which will begin with the strings EV? AT?or RD? respectively, to indicate the current environment. Applications will have to amend queue names accordingly before?EV? ?AT?or ?RD? respectively, to indicate the current environment. Applications will have to amend queue names accordingly before opening the queues.
B. The alias queue names used in the application code will be prefixed with EV? AT?or RD? respectively, so that applications can beThe alias queue names used in the application code will be prefixed with ?EV? ?AT?or ?RD? respectively, so that applications can be promoted between environments without having to change the queue names.
C. WebSphere MQ clustering should be used to resolve queue names and locations dynamically.
D. The names should be identical across the various environments, so that no changes to applications or object definitions between queue managers are required during promotion.
正解：D

質問 7：
An application queue is triggered for trigger type of DEPTH. Following this, what action should the job or program that was started as a result of the trigger take before it ends, so that the queue will be triggered again the next time that trigger depth (TRIGDPTH) is reached?
A. It needs to reset trigger depth (TRIGDPTH) for the queue through an MQSET or ALTER QLOCAL command.
B. No action needs to be taken. The queue manager will create the next trigger message when the current depth of the queue once again reaches trigger depth (TRIGDPTH).
C. It needs to reset trigger depth (TRIGDPTH) and triggering (TRIGGER) for the queue, using MQSET or an ALTER QLOCAL command.
D. It needs to use MQSET or an ALTER QLOCAL command to reset triggering (TRIGGER) for the queue.
正解：D

質問 8：
A weather bureau plans to offer a service to its customers whereby they can receive weather station information (e.g. temperature, humidity) up to one year old. Customer applications should be able to select from which region they want to get datA. What is the best way of implementing such a solution?
A. Store messages in separate queues for each region and use a scheduled process to deleteoutdated messages
B. Store information in a database and access it using a request-reply pattern
C. Store information in a database and access it using a publish/subscribe pattern
D. Store messages in separate queues for each region and use the expiration feature of themessaging system to delete outdated messages
正解：B

質問 9：
A solution depends on messages being dropped during a queue manager restart. These messages are defined as nonpersistent. After a queue manager restarts, the solution designer notes that the messages were not dropped as expected but got processed. Which one of the following options is the likely cause?
A. The application is using permanent dynamic queues
B. The messages reside on a z/OS shared queue
C. The application is putting the messages to a QALIAS with DEFPSIST(NO), however the targetqueue has DEFPSIST(YES) set
D. The application has not set persistence, and the default persistence at the QMGR level isDEFPSIST(YES)
正解：B
