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

1. A partition that uses an LHEA for network connectivity needs to be moved to another managed system. The administrator has the LHEA configured in an Etherchannel with a virtual Ethernet adapter as the backup adapter. When attempting to perform the migration using the Migration Wizard, it fails. What is necessary for the migration to be successful?

A) The LHEA must be removed from the Etherchannel before the migration.
B) The destination server does not have an LHEA available for the migration.
C) The migration must be initiated from the opertaing systems of the mobile partition.
D) The HMC command line interface needs to be used to perform the migration.

2. A Linux LPAR is configured using 802.1Q.
The virtual Ethernet device is configured as an 802.1Q compatible adapter and has VLAN
ID 5 configured in the 802.1Q additional VLAN field.
The administrator runs the following commands on the Linux LPAR shell without errors:
vconfig add eth0 5ifconfig eth0 10.0.0.2 netmask 255.255.255.0
When the administrator tries to ping 10.0.0.1, the request times out.
What is the problem?

A) The VLAN ID should be in the VLAN-ID field in the virtual Network device configuration.
B) The administrator is using the incorrect Ethernet device.
C) The 8021q module is not loaded.
D) The 802.1Q interfaces are not supported on Linux on Power Systems servers.

3. A customer is planning to migrate an existing AIX 7 environment from POWER5 hardware to POWER7. The existing deployment consists of multiple machines, each hosting many LPARs. Due to software licensing constraints, the new environment must maintain the same number of logical CPUs. The pmcycles command reports the following on an LPAR on the POWER5 environment:
$ pmcycles -m CPU 0 runs at 2198 MHz CPU 1 runs at 2198 MHz CPU 2 runs at 2198 MHz CPU 3 runs at 2198 MHz CPU 4 runs at 2198 MHz CPU 5 runs at 2198 MHz CPU 6 runs at 2198 MHz CPU 7 runs at 2198 MHz
How many virtual CPUs should be assigned to the destination LPAR on the POWER7 environment?

A) 8
B) 1
C) 2
D) 4

4. A secondary site is being deployed for application availability and site failover. Servers of identical model and type have been ordered and delivered to the new location.
Additional PowerVM activation keys were obtained for the original location to allow more than 32000 WWNs and enable Active Memory Sharing (AMS).
How can the duplicate systems be updated to enable these additional features?

A) The activation keys must be exported using the PowerVM option within the Capacity On Demand (CoD) panel on the HMC.
B) Activation keys are generated for a specific system and must be generated for each new server in the failover site.
C) Contact IBM Support to generate the one-time password required to administer the PowerVM activation keys.
D) Create a system plan of the existing configuration and deploy this to the duplicate configuration.

5. 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
