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

1. Company policy requires logical volumes to be mirrored across separate disks and controllers for resilience. An administrator needs to create a 2-node cluster with the existing partitions, LPAR1 and LPAR2.The cluster will host an application with data on a shared volume group.
LPAR1 and LPAR2 are currently hosted on a single Power 770. Each partition is assigned two integrated SAS controllers, each of which has internal hard disk drives (HDDs) that are currently used for rootvg.
Which group of actions will create a shared volume group that complies with company storage policy?

A) Assign LPAR1 SAS controllers to dual VIO Servers.
Add HDDs to SAS controller disk bays.
Create virtual SCSI device for new disks and assign to both LPAR1 & LPAR2.
Create shared volume group, ensuring the logical volume copies are across separate HDDs and
virtual SCSI devices.
B) Assign to LPAR1 as "desired" the existing LPAR2 SAS controller.
Add HDDs to LPAR2 existing SAS controller disk bays.
Create shared volume group on new HDDs, ensuring the logical volume copies are across
separate HDDs.
Dynamically assign LPAR2 SAS controllers to LPAR1 and update profile with adapters as
"desired."
Import shared volume group on LPAR1.
C) Assign LPAR1 &LPAR2 two fibre adapters each.
Zone disk from two independent storage servers to each LPAR fibre adapter.
Create shared volume group on new HDDs, ensuring the logical volume copies are across
separate HDDs & storage servers.
D) Add HDDs to LPAR1 existing SAS controller disk bays.
Create shared volume group on new HDDs, ensuring the logical volume copies are across
separate HDDs.
Import shared volume on LPAR2.

2. An administrator is planning a PowerHA implementation for a database and application. The application is dependent on the database being available before the application is started.
If the database is moved from one node to another, the application will need to be re-started. The database and application will be in different resource groups.
How can this be achieved within PowerHA?

A) A sequential processing order for the resource groups can be set, specifying the database and then the application
B) The application can be controlled from a post event to the rg_move_finish event.
C) The application resource group can be configured as a child of the database resource group.
D) The application resource group can be configured as the parent of the database resource group.

3. 9.12.4.11 9.12.4.13
!REQD!ALL 100.12.7.9
!REQD!ALL 100.12.7.10
Given the netmon.cf file above, a single-adapter configuration must recognize a network_down event if a node loses access to_______________:

A) 9.124.11 OR 9.12.4.13
B) 9.124.11 AND 9.124.13
C) 100.127.9OR 100.12 7.10
D) 100.12.7.9 AND 100.12.7.10

4. Which tasks will create and vary on a new volume group for an existing resource group in a 2node cluster?

A) Create a new volume group for the resource group using PowerHA SMIT Menu "Create a Volume Group" on node1 Run PowerHA SMIT Menu "Verify and Synchronize Cluster Configuration"
B) Create a newvolume group using mkvg command on node1 and run importvg on node2 Run PowerHA SMIT Menu "Import a Volume Group" to import the volume group for the resource group
C) Create a new volume group for the resource group using PowerHA SMIT Menu "Configure Storage Resources" on node1 Run PowerHA SMIT Menu "Synchronize a Volume Group Definition"
D) Create a new volume group for the resource group using cl_mkvg command with C-SPOC option on node1 Run PowerHA SMIT Menu "Synchronize a Volume Group Definition"

5. An administrator has installed and configured AIX and PowerHA 7 on multipath vSCSI disks. There are two VIO Servers, and both are accessing the same SAN storage system. The administrator has modified setting for the rootvg system event in the cluster. The cluster is synchronized and stable.
How can the administrator test the rootvg system event to ensure the change behaves as expected?

A) Perform a quick system shutdown using the halt -q command on one node.
B) On both VIO Servers .remove all rootvg disk mappings for one node.
C) Use the HMC to halt one of the VIO Servers which supports the primary MPIO path
D) Delete the rootvg disk devices using the rmdev command.
