IBM Assessment: High Availability for AIX - Technical Support and Administration -v2 Sample Questions:
1. Which utility can be used while a rolling migration is in progress?
A) Resource Groups -> Add a Resource Group
B) System Management (C-SPOC)-> HACMP Services
C) Extended Configuration -> Extended Verification and Synchronization
D) Extended Configuration -> Snapshot Configuration -> Create a Snapshot of the Cluster Configuration
2. A cluster consists of 2 base boot addresses per node. Each boot address can contact the other node in the cluster but is not externally routable. There is one service IP address in cluster which is externally routable.
The external network experienced a problem where the service IP could not be contacted by the users, but the base boot addresses were still able to send heartbeat packets between the cluster nodes. The resource groups did not failover to the other node where there was no network problem.
How can the administrator ensure that the resource groups failover when the service address is not contactable on a node?
A) Configure a persistent IP address on each node.
B) Create a custom application monitor.
C) Create a process application monitor.
D) Configure a post-event script to the fail_interface event.
3. When PowerHA SystemMirror 7.1 is installed on AIX 7.1, what RSCT component does Cluster Aware AIX (CAA) replace?
A) Group Services
B) Topology Services
C) Resource Manager
D) Resource Monitoring and Control (RMC)
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) Set Failure detection rate of diskhb network module to slow.
B) Set Failure detection rate of Ethernet to normal.
C) Create a RS232 heartbeat and set failure detection rate to delay.
D) Dedicate a set of disks for disk heartbeat and set failure detection rate to delay.
5. An administrator is configuring a PowerHA 6 cluster to use disk heartbeat as a non IP network. A shared volume group, dhbvg, has been configured using a single disk, hdisklO, on NodeA and NodeB.
The administrator believes that the prerequisites have been met, but would like to test connectivity of the disk heartbeat network before adding the network into the cluster.
How can the connectivity of this disk heartbeat network be tested?
A) On NodeA run the command/usr/sbin/rsct/bin/dhb_read-p hdisk10-r On NodeB run the command /usr/sbin/rsct/bin/dhb_read-p hdisk10-t
B) On NodeA run the command "echo 1 | /usr/bin/dd of=/dev/rhdisk10 bs=4K skip=2 count=1" On NodeB run the command/usr/bin/dd if=/dev/rhdisk10 bs=4K skip=2 count=1"
C) On NodeA run the command /usr/bin/readvgda-V dhbvg -F status On NodeB run the command /usr/bin/putvgda-V dhbvg -a status=1
D) On NodeA run the command /usr/sbin/rsct/bin/dhb_transmit hdisk10 On NodeB run the command /usr/sbin/rsct/bin/dhb_receive hdisk10
