Question 1
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?
- Only run the command mqsiwebuseradmin
- Only ensure that broker administration security is active.
- Define security and roles at the Operating system level.
- Ensure broker administration security is active and run the command mqsiwebuseradmin
Correct answer: D
Question 2
A company has a shared broker environment where each department uses their own execution group. A department's application team wants to increase the throughput of a specific flow. What should the system administrator do to increase the overall through-put without any additional administrative overhead?
- Create multiple BAR files with the same flow and deploy them.
- Create copies of the message flow and deploy them separately.
- Configure the Additional Instances parameter of the message flow to 20.
- Configure the Additional Instances parameter of the message flow to 260.
Correct answer: C
Question 3
A system administrator is asked by the development team to enable gathering of statistics for GlobalCache and DotNetGC and used by applications deployed to execution group EG1 running on broker BRK1. Which commands does the system administrator need to issue?
- mqsistop BRK1mqsireportresourcestats BRK1 -c active -e EG1mqsistart BRK1
- mqsistop BRK1mqsichangeflowstats BRK1 -c active -e EG1 -s mqsichangeflowstats BRK1 -c active -e EG1 -s ?mqsistart BRK1
- mqsistart BRK1mqsichangeresourcestats BRK1 -c active -e EG1
- mqsistart BRK1mqsichangeflowstats BRK1 -c active -e EG1 -s -f All
Correct answer: C
Question 4
A system administrator defined one execution group per partner system. Recently, one of the partner systems developed 5 new message flows that processed messages containing large number of repeating elements. The system administrator is asked to tune the DataFlowEngine before deploying these new message flows. How should the system administrator do this?
- Reduce the stack size.
- Reduce the maximum JVM Heap size.
- Increase the stack size.
- Increase the maximum JVM Heap size.
Correct answer: C
Question 5
A message flow has been deployed with monitoring activated. A system administrator is asked to generate additional monitoring events on the message flow for transaction auditing without redeploying the flow. How should the system administrator do this?
- Create a monitoring profile configurable service and apply it to the message flow.
- Use the Message Broker Explorer to change the monitoring events for the message flow.
- Update the monitoring event source and properties for the message flow using the command mqsireload.
- Reconfigure the monitoring event source and properties for the message flow using the command mqsichangebroker.
Correct answer: A
Question 6
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?
- Reduce the stack size.
- Reduce the minimum JVM Heap size.
- Increase the stack size.
- Increase the minimum JVM Heap size.
Correct answer: B
Question 7
A system administrator is asked to set up the statistical and account data collection for all message flows deployed in the execution group EG1 of broker BRK1 for billing purposes. The system administrator executes command mqsichangeflowstats BRK1 -s -e EG1 -j -c active -n basic. What does the administrator need to do to receive the statistical and account data?
- Run command mqsichangebroker to reset data collection interval.
- Run command mqsichangeproperties to define the output destination.
- Run commands mqsireadlog and mqsiformatlog to process the output data from the user trace log.
- Subscribe to $SYS/Broker/BRK1/StatisticsAccounting/snapshot/EG1/# to get the publication message.
Correct answer: C
Question 8
An application team consults with a system administrator on ways to increase the response time of one of their message flows. The system administrator is also informed that the messages are not that critical, peak volumes are very high and response time should be very low. The system administrator performs a quick analysis of the system data during peak volume processing and notices that the CPU utilization is moderate but I/O operations are very high. How should the administrator suggest improving the message flow response time?
- Change the messages from persistent to non-persistent.
- Create a new execution group and deploy additional instances.
- Increase the Additional Instances of the message flow.
- Increase the maximum JVM Heap Size of the execution group.
Correct answer: A
Question 9
A system administrator executes the command mqsirestorebroker to restore a broker on a QA environment. However, it is found that the backup file used contains incomplete information associated with the broker. Which of the following situations may result in the failure during creating the backup file?
- The broker is stopped.
- The execution groups are running.
- A deployment is in progress.
- A message flow with an HTTPRequest node is receiving input messages.
Correct answer: C
Question 10
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?
- mqsideploy BRK1 -e EG1 -a Request.bar -mmqsideploy BRK1 -e EG1 -a Quote.bar
- mqsideploy BRK1 -e EG1 -a Quote.bar -d Req.cmf -mmqsideploy BRK1 -e EG1 -a Request.bar -m
- mqsideploy BRK1 -e EG1 -a Quote.bar -d Request.cmfmqsideploy BRK1 -e EG1 -a Request.bar
- mqsideploy BRK1 -e EG1 -a Request.bar -d Req.msgflowmqsideploy BRK1 -e EG1 -a Quote.bar -d Quote.msgflow -m
Correct answer: A
