What does OBPAR allow on a PowerEdge MX750c?

Question

Options

• ARun a compute sled with memory overclocking.
• BBoot a compute sled with only one CPU.
• CRun a compute sled with maximum performance.
• DBoot a compute sled with reduced frequency.

• A
  7% (2)
• B
  4% (1)
• D
  89% (25)

Explanation

OBPAR (One Boot with Partial Available Resources) is a Dell PowerEdge feature that permits a compute sled to boot at a reduced CPU frequency when full operating conditions aren't met - making D correct. It's a controlled degraded-state boot, not a normal full-performance startup.

Why the distractors are wrong:

• A (memory overclocking) - OBPAR has nothing to do with memory speed manipulation; overclocking is a separate concern and not a supported Dell enterprise feature here.
• B (only one CPU) - Single-CPU boot is a distinct configuration option unrelated to OBPAR; OBPAR is about frequency reduction, not processor count.
• C (maximum performance) - OBPAR is the opposite of maximum performance; "Partial" in the name signals a compromised/reduced operational state.

Memory tip: Break down the acronym - One Boot, Partial resources. "Partial" is your clue that something is running at less than full capacity, which maps directly to reduced frequency. If you see "OBPAR," think "partial = reduced."
