IBM Assessment: Virtualization Technical Support for IBM i -v1 Sample Questions:
A customer has a single partition Power 720 running IBM i with PowerVM Express, LAN Console, and extra disk and memory capacity.
Management wants a small IBM i partition added to the system for testing.
Which option supports the requirement with minimal disruption to production?
- A. Acquire an HMC and partition the system.
- B. Implement VIO Server to host the test partition.
- C. Implement VIO Serverto host both partitions as clients.
- D. Create a guest IBM i partition on the existing partition.
Correct Answer: D 🗳️
A customer has a single-partition Power 720 running IBM i. They would like to install some additional adapters and implement 5 additional partitions. In addition to installing the adapters and configuring an HMC, what else is necessary?
- A. Modify the existing partition profile to not "use all resources in system" and own only what it
needs. Reactivate the profile.
Create partitions and profiles for the additional partitions. - B. Modify the profile of the existing partition and concurrently enable it.
Resume the existing partition.
Create partitions and profiles for the additional LPARs. - C. Create a new partition and profile for the original LPAR with only the resources the partition
needs. Create partitions and profiles forth additional partitions.
Delete the original partition.
Suspend the existing partition. - D. Configure the new partitions.
Activate the new profiles to remove "required" features of the existing partition.
Correct Answer: C 🗳️
A customer with an IBM i environment containing an iASP runs a Save 21 monthly. Normally the save takes about 5 hours. This month, the save took less than an hour. No errors were encountered on the save, and the amount of data in *SYSBAS and the ASP hasn't changed significantly. What is the most likely explanation for the difference in time required to process the save?
- A. The ASPGRP was not correctly set in the backup job description.
- B. Entry to the iASP was locked by a system task.
- C. The iASP was notvaried on before the Save 21 was processed.
- D. The user performing the save didn't have *ALLOBJ authority.
Correct Answer: C 🗳️
A new IBM i client partition has been created. Storage for the client partition is being provided by a hosting IBM i partition.

What is the most likely reason?
- A. Shared memory has not been enabled in the hosting partition.
- B. The processor settings are "capped" rather than "uncapped."
- C. I_BASE_01 media is not in any accessible optical or virtual optical drive.
- D. Power control has not been properly configured.
Correct Answer: D 🗳️
What IBM software is the minimum required to share an IBM tape library connected to multiple IBM i partitions using NPIV?
