IBM High Availability for AIX - Technical Support and Administration -v2 Sample Questions:

1. What does the following notification from node Jessica mean?
EVENT COMPLETED: server_down Jessica 12 testapp 0

A) Jessica is reporting that another node is down
B) Jessica has failed
C) Jessica was taken offline
D) An application on Jessica has failed

2. The administrator has written a script "correct_problem.sh" that needs to be run if the "release_vg_fs" event does not complete successfully.
What should be done to ensure the correct_problem.sh is called a maximum of 3 times if the event failed?

A) Include a recovery command of correct_problem.sh and a recovery counter of 3
B) Include a custom event of correct_problem.sh and a restart limit of 3
C) Include a post event of correct_problem.sh and a retry counter of 3
D) Include a retry command of correct_problem.sh and an event counter of 3

3. A cluster resource group has following application server characteristics:
An application server start script starts process A and process B.
An application monitor with the following settings: long-running, monitor interval=60, stabilization interval=180
The monitor method checks process B. and if process B is down it restarts process B and exits with return code 0.
When the cluster is started, an administrator finds process A is down and output of cluster.mmddyyyy log file is as follows; What happened?

A) Application server start script succeeded, but process B was down and restarted after stabilization timer interval.
B) Application server start script has hanged, and monitor method started process B after stabilization timer interval.
C) Resource group went offline because Node1 failed to acquire some resources
D) Application server start script was not invoked because monitor method returns 0 when process B is down.

4. A PowerHA 6 cluster uses IPAT with aliasing and disk heartbeat. The administrator noticed the standby node crashes during a failover test. There are entries related to the Dead Man Switch (DMS) timeout in the AIX error log.
Which action is recommended to reduce the risk of DMS timeouts?

A) Create a RS232 heartbeat and set failure detection rate to delay.
B) Set Failure detection rate of Ethernet to normal.
C) Dedicate a set of disks for disk heartbeat and set failure detection rate to delay.
D) Set Failure detection rate of diskhb network module to slow.

5. An administrator has a 2-node cluster and has chosen the C-SPOC option to bring a resource group offline. The resource group was stable on the primary node prior taking resource offline, however it has gone into an error state. The administrator corrects the error and issues the clruncmd to continue cluster processing.
What will happen to the resource group?

A) The resource group goes offline.
B) The resource group falls over to the remaining active node.
C) The resource group remains in error state until services on all cluster nodes are stopped and restarted.
D) The node shuts down and the resource group goes into temporary error state.
