IBM Virtualization Technical Support for IBM i -v1 Sample Questions:
Question #1
When using SAN flash copy to clone a disk image for an IBM i client LPAR, message 'CP1096E Disk unit connection is missing' appears in the history log of the newly created client LPAR.
A check in SST shows the expected disk paths as 'active' and extra disk paths with a status of 'missing', a result of the reconfiguration of the disk subsystem.
What is necessary to avoid the warnings and to clean up the disk paths?
A. Run the multipath resetter Advanced Analysis macro in SST.
B. Remove the missing path(s) through Hardware Service Manager.
C. Use the Disk Path Manager tool in System Director Navigator.
D. Re-IPL the system.
Question #2
There are three Power Systems servers with redundant FSPs, and two HMCs. One HMC is in the data center while the second is in operations. Each HMC is connected to its own private network and each of the three systems are connected to both HMCs.
Two of the Power Systems servers and the HMC in the data center have been moved across the room. They have been reconnected to the HMC network, and power has been applied to the HMC and the first server. On the data center HMC the server shows up twice, once with "Authentication failed" and the second with "no connection." Connecting to ASM yields "incorrect password" on the first instance, but works on the second instance.
What the most likely cause?
A. Power was applied to the server before the HMC was up and running.
B. The service processors have different HMC access passwords.
C. The data center and operations HMCs are now on the same network.
D. The firmware on the service processors is out of sync.
Question #3
Auditors have reviewed access to the HMC and determined that many users have too much authority. What is the correct method to restrict users to only a specific set of tasks?
A. Change the users'task role to hmcoperator.
B. Create and assign a new resource role that allows access to only the required resources.
C. In Manage Users and Tasks, check each task that is needed for this user.
D. Create and assign a new task role that allows only the required set of tasks.
Question #4
What is the correct sector size to select when reformatting disk drives from AIX for use on IBM i?
A. 128bytes
B. 5l2bytes
C. 520 bytes
D. 256 bytes
Question #5
A customer has several client IBM i partitions, hosted by other IBM i partitions. Corporate IT policy specifies that certain optical and tape resources must not be available to client IBM i partitions. How can these resources be made unavailable to the client partitions?
A. Remove the unneeded hardware from the hosted partition's profile on the HM
B. Secure the device descriptions on the hosting partition with an authorization list.
C. Specify only the devices to be available in the Network Server Description.
D. Specify the devices to be unavailable in the Network Server Description.
