Which command does the system administrator need to execute to start the controlled failover process?

Question13: A system administrator is trying to configure an existing multi-instance broker BRK1 as a WebSphere MQ service so that the broker starts and stops automatically when its associated queue manager starts and stops. Which command does the system administrator have to run?

Question14: A system administrator has been asked to migrate an existing broker installation on AIX from WebSphere Message Broker V7.0 running with WebSphere MQ V7.1 to WebSphere Message Broker V8.0. The existing broker consists of message flows that use publish-subscribe functionality as well as access a DB2 database from compute nodes. The administrator installs the broker component in a new location on the AIX machine, removes the broker from the domain configuration and stops the broker. Which of the following additional steps does the system administrator need to perform to complete the migration?
(Choose two.)

Question15: A company has multiple users that access broker using web user interface. The system administrator of the company has been asked to define security for a group of users in such a way that user1 is able to view all the broker resources, user2 is able to view and modify all the broker resources and user3 is able to view and modify selected broker resources. What does the system administrator need to do?

Question16: A system administrator is designing an active-active, high availability configuration to WebSphere Message Broker using two nodes. Which are the minimum components required in each node for this configuration?

Question17: A system administrator is asked to deploy updated code to execution group EG1 running on broker BRK1.
There are 2 message flows deployed to the execution group. After a review, it was found that the deployed flow Req.msgflow should have been named Request.msgflow. The other flow Quote.msgflow needed to be updated to accommodate a bug fix. The updated flow code is provided to the system administrator with all of its dependent resources in two separate BAR files (Request.bar and Quote.bar). Which commands does the system administrator need to issue to successfully deploy the new BAR files?

Question18: A system administrator upgraded the WebSphere Message Broker runtime to the latest Fix Pack. After the upgrade, when the system administrator tries to start the broker BRK1, one of the execution groups EG1 does not start. The broker repeatedly shows BIP2060W in the broker syslogs on that execution group. The system administrator checked the install logs and finds that the Fix Pack was installed successfully. The system administrator searches the web for any known problems, but does not find any hits. The system administrator decides to capture a startup trace on the execution group to see if any diagnostic information can be detected. What should the system administrator do to initiate the trace?

Question19: A system administrator is monitoring the Activity Logs in WebSphere Message Broker Explorer and notices the following error:

Which component caused the error?

Question20: A system administrator runs the following command in an environment where EG1 is an execution group running under broker BRK1 mqsistartmsgflow BRK1 -e EG1 -k App1 -m F1 What can the system administrator expect from the successful execution of the command?

Question21: An established insurance (parent) company has legacy applications that require data in the COMMAREA format. It has acquired a small insurance (child) company with applications that use the XML format for application communication. The parent company wants to use the child company's web customer portal.
This requires interaction between the legacy and modern application to process a transaction. How should the system administrator implement this requirement?

Which additional database configuration steps does the system administrator need to perform on BRK1 to enable recording of messages processed by a message flow F1 in execution group EG1?

Question24: An application team informs the system administrator that a new flow has performance issues. The system administrator does the analysis and notices that although the flow contains less than 10 nodes and does not contain any complex logic, it is processing very large messages. What should the system administrator do to enhance the DataFlowEngine performance?
