Demo Questions
Question 1
Which two automatic migration scenarios require node manager for all migratable services? (Choose two.)
- Consensus leasing
- Database leasing with no pre and post migration scripts
- Database leasing with pre and post migration scripts
- Synchronous leasing
Correct answer: AC
Explanation:
When using automatic service migration, the Node Manager is required to get health monitoring information about the member servers involved, as follows:Consensus leasing – Node Manager must be running on every machine hosting managed servers within the cluster. Database leasing – Node Manager must be running on every machine hosting managed servers within the cluster only if pre/post-migration scripts are defined. If pre/post-migrations are not defined, then Node manager is not required.

Question 2
Which two statements are true about the role of cluster master in whole server migration? (Choose two.)
- There is exactly one cluster master in the cluster at a given point of time.
- The cluster master must host all the pinned services in the cluster.
- Any managed server in the cluster can serve as the cluster master.
- A cluster master must always be different from a singleton master.
- The cluster master must always be started with the node manager.
Correct answer: AC
Explanation:
One server instance in a cluster that contains migratable servers acts as the cluster master and orchestrates the process of automatic server migration, in the event of failure. Any Managed Server in a cluster can serve as the cluster master, whether it hosts pinned services or not. Note: Any server instance in the cluster can serve as the cluster master. When you start a cluster that contains migratable servers, the first server to join the cluster becomes the cluster master and starts up the cluster manager service. If a cluster does not include at least one migratable server, it does not require a cluster master, and the cluster master service does not start up.Reference: https://docs.oracle.com/cd/E12839_01/web.1111/e13709/migration.htm#CLUST285 One server instance in a cluster that contains migratable servers acts as the cluster master and orchestrates the process of automatic server migration, in the event of failure.

Question 3
You are trying to set up a JMS Session with a specified acknowledgment mode. You want the application that receives the message to explicitly take care of the acknowledgment.
Which option represents a valid choice for the acknowledgment mechanism that you can use? (Choose the best answer.)
- AUTO_ACKNOWLEDGE
- CLIENT_ACKNOWLEDGE
- DUPS_OK_ACKNOWLEDGE
- DEFAULT_ACKNOWLEDGE
Correct answer: B
Explanation:
With CLIENT_ACKNOWLEDGE the Session object relies on the application to call an acknowledge method on a received message. Once the method is called, the session acknowledges all messages received since the last acknowledge. Incorrect Answers:A: With CLIENT_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it.C: With DUPS_OK_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it; duplicate acknowledges are permitted.D: There is no acknowledge mode named DEFAULT_ACKNOWLEDGE.Reference: http://docs.oracle.com/cd/E12840_01/wls/docs103/jms/fund.html With CLIENT_ACKNOWLEDGE the Session object relies on the application to call an acknowledge method on a received message. Once the method is called, the session acknowledges all messages received since the last acknowledge.
Incorrect Answers:
A: With CLIENT_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it.
C: With DUPS_OK_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it; duplicate acknowledges are permitted.
D: There is no acknowledge mode named DEFAULT_ACKNOWLEDGE.
