EMT Practice Test

1. Question Content...

---

Question1: A BAR file including a message flow with MQInput node is deployed to a test environment. After the test is successfully completed, an administrator is asked to deploy the same BAR file to the UAT environment.
The administrator uses the broker archive editor to change the queue name in MQInput node. However, after clicking build broker archive the queue name does not change.
What does the administrator need to do?

Question2: The broker environment in a company is as follows: The administrator has set up Public Key Infrastructure (PKI) at the broker level. For the flows that contained SOAP Input nodes, the administrator has set up PKI at the execution group level. The administrator also configured the broker-wide listener for the HTTP node based web services. In this environment, the administrator was asked to deploy a new secured web service based on HTTP nodes in the same execution group that contained SOAP node based web service.
After a few days the partner system that was making HTTP(s) calls to this new web service reported SSL certificate expiry errors.
What should the administrator do to resolve this problem?

Question3: An administrator needs to deploy several BAR files to the same execution group (EG) using WebSphere Message Broker Explorer. Not all of the BAR files are in the WebSphere Message Broker Explorer workspace. How can the administrator perform the task in one step?

Question4: An administrator needs to gather a detailed user level trace to diagnose an issue with a flow F1 in execution group EG1 on broker MB7BROKER.

What command does the administrator then run?

Question5: An administrator has enabled broker admin security for a broker running in Windows Server. The administrator is notified that a new user needs to have view access of all the execution groups and the associated flows in the broker. The administrator grants authorizations to the user on the following queues:

Question6: An administrator needs to use WebSphere Message Broker 7.0 with an existing high availability (HA) manager HACMP. The administrator has created and added the broker to the HA environment. How should the administrator start the broker?

Question7: A flow MF has been configured to generate transaction start monitoring events on a production system.
The administrator is notified that another flow AF deployed in the same execution group has to be configured to generate similar transaction start monitoring events with the least downtime and changes to the flow. The administrator performs the following sequence of steps: 1. Uses the command mqsireportflowstats to generate the monitoring profile for flow MF and updates it to reflect changes for flow AF. 2. Uses the commands mqsicreateconfigurableservice and mqsichangeproperties to create a new configurable service with the updated monitoring profile.
Which additional step does the administrator need to perform to achieve the objective?

Question11: An application developer configures message flow MF to generate monitoring events and deploys it on execution group EG of broker BRK. The application developer creates a new subscription to listen to event messages being generated for MF on a specific queue MF.SUB.QUEUE. The administrator later gets notified that there are no event messages being generated on MF.SUB.QUEUE even though messages are being processed by the flow MF.
What command does the administrator need to run to enable MF to generate the events?

Question14: A message flow that includes HTTP nodes is deployed to 3 execution groups in a broker. All HTTP nodes are configured to use a single port.
