D. Include data encryption algorithms in both sending and receiving applications
Answer: C

7. An enterprise uses WebSphere MQ to connect 60 branch offices and 10 regional offices to a central CICS transaction server. The branch offices all run HP-UX systems using TCP/IP to connect to the central host. The regional offices all run iSeries systems and connect via SN A. There are 20 new CICS business functions.
How many new WebSphere MQ application queue should be defined on the central host?
A. 1
B. 10
C. 20
D. 60
Answer: C

8. On Windows and UNIX platforms, which process should be used to take a full backup of a WebSphere MQ V5.3 queue manager’s data?
A. Take down the queue manager, then use operating system functions to back up the queue manager’s data structures and log files
B. Take down the queue manager, then use operating system functions to back up the queue manager’s data structures
C. Run bkupqmgr from a command line, specifying the queue manager name and the name of the directory where the backup is to be created
D. Use operating system functions to back up the queue manager’s data structures and log files.
Answer: A

9. Certkiller .com is creating a backup and recovery plan for a WebSphere MQ application to be implemented on a z/OS system.
Which of the following is a disadvantage of a full backup?
A. A full backup requires dual logging
B. A full backup requires more DASD space than a fuzzy backup
C. A full backup page set cannot be used to recover if the logs are damaged or lost
D. A full backup requires a queue manager shutdown
Answer: D

10. An organization created an application environment where an Active x control was invoked by a VBA scriptinside Excel spreadsheets. This was done to subscribe to a publication and then to incorporate incoming published data into the spreadsheet. A single queue was shared by all subscribers and the correlation ID was used to differential between subscribers. A timestamp based unique value for the correlation ID was created upon startup. After a few days the queue was found containing an excessive number of messages. Which of the following measures can be used to overcome this problem?
A. Assign each subscriber his own queue
B. Expire all relevant subscriptions after 18 hours
C. Increase the maximum number of messages attribute of the queue
D. Increase the maximum message size attribute of the queue
E. Decrease the number of users concurrently allowed on to the system
Answer: A,B,D

11. Which of the following considerations are MOST important for deploying a WebSphere MQ server in preference to a WebSphere MQ client?
A. If applications update MQ resources and database resources
B. If local application performance is critical
C. If reliable delivery is required
D. If the application machine is resource constrained
E. If the application must be able to run independently of the network
Answer: B,E

12. An application has been developed to take advantage of the WebSphere MQ shared queue feature. One of the application queue is shared between two z/OS LPARs. As a result of a new requirement, another application now requires that the messages on this queue become available to a cluster. Which of the following actions is MOST appropriate to recommend?
A. Change the queue such that it is only a clustered queue
B. Change the queue such that it is both a shared and a clustered queue
C. Copy all messages from the shared queue to a clustered queue
D. Advise that the two WebSphere MQ features are incompatible
Answer: B

13. A large enterprise, running on a group of z/OS machines, wishes to produce and maintain a central configuration repository for WebSphere MQ from which reports can be produced and information generated about the structure of the system.
Which of the following methods is MOST appropriate for gathering the data for this repository?
A. Enable CONFIGEV and redefine SYSTEM.ADMIN.CONFIG.EVENT as a remote queue on each queue manager, pointing to a single local event queue
B. Run the SAVEQMGR program and combine the various reports into a single file
C. Write a PCF program that issues INQUIRE commands and run it on each queue manager, sending the results to a central queue
D. Write an application program that issues MQINQ calls and run it on each queue manager, sending the results to a single queue
Answer: A

14. An architect has designed an AIX application that will update WebSphere MQ queues and a DB2 database within a single unit of work, using WebSphere MQ as the transaction manager. The architect wishes to be sure that all possible recovery options are covered within the application in the case of a failure of the transaction.
In which of the following circumstances should the architect prepare additional manual recovery procedures?
A. If the application crashes within the unit of work before the MQCMIT
B. If the database crashes within the unit of work before the MQCMIT
C. If the database crashed during the MQCMIT, before the database indicates that it is prepared to commit
D. If the database crashed during the MQCMIT after the database indicates it is prepared to commit
Answer: D

15. An application requires to implement a form of workload management. Although feasible "push" workload management does not particularly suit the requirements. Which of the following WebSphere MQ features can be described as enabling pull workload management?
A. Cluster queues
B. Shared queues
C. Workload Management Exit
D. Message Channel Agent
Answer: B

16. A large financial institute wants to use WebSphere MQ clients which will connect to a single queue manager in a local LAN attached server. The desktop workstations and server are running Windows 2000. This configuration will be replicated to several hundred branch offices, each with 30 to 50 workstations. The customer wants to achieve a level of security for accessing applications by user class and has defined three user classes. It is imperative that minimum administrative data and processes reside on the desktop workstation. In addition, none of the end users will be granted mqm or administrative group authority.
Which of the following alternatives BEST satisfies this environment?
A. Define an MQI client channel for each class of user on the workstation and setMQ_USER_ID and MQ_PASSWORD specific to the user class
B. Implement a security exit on the client to enforce user class and pass MQ_USER_ID and MQ_PASSWORD to the server
C. Define SVRCONN channel on the server with a MCAUSER specification for each of the three user classes
D. Set the desired user ID in the inetd .conf file associated with the TCP/IP listener on the server
