Which statement about LPAR is true?

• A. Partitions are always able to communicate with each other by default.
• B. LPAR uses a single operating system across all partitions.
• C. Partitions can run their own distinct copy of the operating system and applications.
• D. Partitions cannot share hardware resources like memory.

Answer: (C)

LPAR is a virtualization approach that divides one physical server into multiple logical partitions. Each partition acts like its own server with its own operating system and applications, isolated from the others. This setup lets you run different OSes or different software stacks on the same hardware while keeping processes and data separate.

That makes the statement about partitions running their own distinct copy of the operating system and applications true: each partition can host its own OS instance and its own applications, independently from the others.

Partitions are isolated by default; they don’t automatically communicate—any interaction requires explicit networking or I/O configuration.

While the physical hardware is shared, each partition gets its own allocated memory and resources; the claim that partitions cannot share memory is not accurate.
