What is the maximum supported PowerStore volume size in TB?
The correct answer is C. 256. Dell EMC PowerStore supports a maximum volume size of 256 TB, making option C correct. This limit applies to both block volumes and is consistent across PowerStore's current architecture for primary storage workloads. Why the distractors are wrong: A (64 TB) - This is a common…

Explanation
Dell EMC PowerStore supports a maximum volume size of 256 TB, making option C correct. This limit applies to both block volumes and is consistent across PowerStore's current architecture for primary storage workloads.
Why the distractors are wrong:
- A (64 TB) - This is a common maximum for older or entry-level storage arrays (e.g., some Unity or older VNX configurations), not PowerStore.
- B (123 TB) - Not a real architectural limit for any major Dell storage product; it's a plausible-sounding number designed to trip you up.
- D (512 TB) - While large enterprise arrays can support massive capacities at the system level, 512 TB exceeds PowerStore's per-volume maximum.
Memory tip: Think "256 = 2^8" - PowerStore's max volume size is a clean power-of-two (256 TB), which is typical of how storage vendors align limits to binary boundaries. If you remember "PowerStore = 256 TB max volume," you can immediately rule out any option that isn't 256.
