IBM Virtualization Technical Support for IBM i -v1 Sample Questions:
Question 1
A customer is experiencing disk performance issues on a client IBM i LPAR. The hosting IBM i partition is utilizing 50 internal disks. Both the host and the client partition disks are less than 50% full.
Which option is most likely to improve performance of the client IBM i partitions?
A. Use the STRASPBAL *USAGE utility.
B. Utilize smaller Network Server Storage Spaces, but the same quantity.
C. Increase the queuing depth of the disks to the maximum allowed.
D. Utilize a user ASP for the Network Server Storage Spaces.
Question 2
A customer needs to replace a failed tape controller card on a running partition. The service action Serviceability-> Hardware -> Exchange ERU has been started. The card has been selected and the service action has been launched.
The message "The requested service action cannot currently be completed from this management console" is displayed.
What is the most likely reason for this error?
A. The adapter has not been deallocated from the partition.
B. The partition is controlled by another HMC in the environment.
C. The tape device associated with the adapter is notvaried off.
D. The service domain for the partition is still active.
Question 3
A client IBM i partition is implemented across two VIO Servers (VIOS) and the network is configured with SEA failover.
VlQS-1 is configured as the primary network path, and VIOS-2 as the secondary.
When VIOS-1 is removed for maintenance purposes, the client IBM i partition network traffic moves to VIOS-2.
What is the result when VIOS-1 returns to a running state?
A. The client IBM i partition continues to access the network through VIOS-2.
B. Access to the network from VlOS-1 is returned after the virtual Ethernet adapters are DLPARed back in.
C. The network will revert automatically to VIOS-1.
D. The client IBM i partition begins to use both VIQ Servers to access the network.
Question 4
A customer is implementing a new POWER7 system that will run along with an older POWER5 system.
A new HMC has been purchased for the POWER7 system.
The older 7310-CR3 HMC for the POWER5 system will remain in service.
The customer wants the older 7310-CR3 provide back up to the new HMC.
What must be done prior to implementing the customer's requirements?
A. Connect the new HMC to the POWER7 system and to the LAN.
Use the "Transmit Service Information"dialog on the new HMC to update the 7310-CR3 with the
new HMC code and firmware for the FSP.
Update the firmware on the POWER5 system and connect the new HMC.
B. Consult the HMC / Firmware Supported Combinations chart to obtain the proper firmware/HMC
code levelsimplementthe firmware updates on the POWER5 and 7310-CR3 HMC first,
Connectthe 7310-CR3 to the POWER7 system.
C. Upgrade the POWER5 system firmware to the same fix pack level that the POWER7 system is
running. Upgrade the 7310-CR3 to the latest version of HMC code.
Connect both systems normally to the 7310-CR3
D. Ensurethe POWER7 ESP is running in "Dual Mode"with the"Activated Level"setto supportthe
POWER7 system and the "Deferred Level"set to support the POWER5 system.
Connect the 731 O-CR3 with the "Deferred Level"password.
Question 5
In the following example, the VIO Server partitions each provide disk to a client IBM i partition. The client IBM i partition has mirrored the disk presented to it.
Contact with one VIO Server is lost, and the disk it presents to the client shows as "suspended" in IBM i. Once contact has been re-established, what action must the administrator take?
A. Run the varyonvg command on bothVIOServers.
B. Run the varyonvg command on theVIOServer providing the failed disk. From System Service Tools, resume mirroredprotection in the client partition.
C. Recover the disk with the mdadm command on the VIO Server providing the failed disk.
D. Use System Service Tools to verify and resume mirroring, if necessary.
