IBM Cloud Pak for Data v3.0 Solution Architect — Question 3

Which of the following statements is true regarding Dynamic Logical Partitioning (DLPAR)?

Answer options

• A. In a disaster, it will immediately move active LPARs from a local system to a remote system, over the network with only a pause in service.
• B. In a disaster, it will immediately move active LPARs from a local system to another local system, using a common SAN, with only a pause in service.
• C. It enables the relocation of resources such as CPU and memory between LPARs as required, without an interruption in service.
• D. It will automatically allocate an unlicensed processor to an LPAR to replace one that has reached the threshold for errors.

Correct answer: D

Explanation

The correct answer is D, as DLPAR is designed to dynamically allocate resources such as processors to LPARs, particularly when existing resources are failing. Options A and B are incorrect because DLPAR does not handle disaster recovery by moving LPARs to remote or local systems. Option C is misleading because while DLPAR allows for resource allocation, it does not specifically address the replacement of failing processors.
