IBM Assessment: Power Systems Virtualization Technical Support for AIX and Linux -v2 Sample Questions:

1. An administrator has dynamically allocated a new virtual FC adapter to an AIX client. When running cfgrngr on the client, the administrator receives the following error:
Method error (/usr/lib/methods/cfg_vfc -I fcs0):
0514-040 Error initializing a device into the kernel
Which of the following could explain the error?

A) The client adapter has been configured to use a 32bit kernel.
B) The physical fibre channel adapter on the VIO server does not support NPIV.
C) The client adapter has been configured to use an invalid virtual server adapter
D) The fileset devices.vdevice.vfc-client.rte needs to be installed.

2. A redundant pair of VIO Servers is used to virtualize the same SAN LUNs to a number of AIX LPARs. To ensure that Multipath 10 is correctly configured an administrator sets the appropriate device attributes on the vSCSI disks on the clients.
One of the VIO Servers was shut down for 5 minutes to simulate a failure. After the VIO Server was brought back online, the administrator found that some LPARs recovered their storage paths automatically, yet some LPARs did not recover their paths at all.
How can the administrator recover from the lack of path recovery?

A) Reduce the number of paths to the LUNS to 6 or less.
B) Reboot the client LPARs.
C) Allocate both vSCSI adapters to the client LPARs.
D) Update SDDPCM to a level higher than 2.1.2.3.

3. A VIO server requires redundancy on its Shared Ethernet Adapter (SEA). The SEA is backed by physical adapter ent0 and virtual adapter ent2, ent0 and ent1 are the interfaces on a dual-port Ethernet adapter.
What network redundancy technique should be suggested?

A) Create a new SEA using another virtual Ethernet adapter on the VIO Server and assign ent1 as the backing device. Assign this SEA to the clients and setup Link Aggregation on the clients.
B) Setup the SEA failover control channel to use the ent1 physical adapter as the backup control channel.
C) ent1 should be used to set up Link Aggregation through 'smitty linkagg1. The new Link Aggregation adapter should be used as the backing device for the SEA
D) ent1 should be used to set up a Network Interface Backup through 'smitty etherchannel1. The new Etherchannel adapter should be used as the backing device for the SEA

4. When installing a Linux LPAR from an AIX NIM server, what steps are required?

A) Configure LPAR as a NIM client Copy DVD to local directory Configure Linux SPOT Boot into SMS and configure remote IPL settings
B) Add LPAR details to /etc/bootptab Copy DVD to a local directory and add directory to /etc/exports Copy network boot kernel to /etc/tftpboot Boot into SMS and configure remote IPL settings
C) Copy DVD to local directory and export via /etc/exports Copy network boot kernel to /etc/tftpboot Define LPAR as a NIM client and initiate a bosinstall Boot into SMS and configure remote IPL settings
D) Add LPAR details to /etc/tftp/other/kernel.conf Copy DVD to local directory and add to /etc/exports Copy network boot kernel to /tftpboot/kernels Boot into SMS and configure remote IPL settings

5. Which is the lowest edition of PowerVM that will permit redundant VIO Servers?

A) PowerVM Enterprise Edition
B) PowerVM Basic Edition
C) PowerVM Standard Edition
D) PowerVM Express Edition
