Which statement about LPAR is true?

Which statement about LPAR is true?

• A. All partitions must communicate with each other by default.
• B. LPAR uses a single operating system across all partitions.
• C. Partitions cannot run their own distinct copy of the OS.
• D. Partitions subdivide a system's resources into smaller units that can run with their own distinct copy of the operating system and applications.

Answer: (D)

LPAR creates independent partitions on the same physical system, each with allocated resources and the ability to run its own operating system and applications. This setup allows separate environments to operate in isolation, sharing hardware while not forcing a single OS across all partitions. Therefore, the true statement is that partitions subdivide the system's resources into smaller units that can run with their own distinct copy of the operating system and applications. The other ideas aren’t accurate: partitions don’t have to communicate by default; you configure networking between them as needed, and you can run different OS instances in different partitions rather than a single shared OS.
