A customer needs a new high frequency trading cluster. Their current cluster has non- deterministic performance and undesirable latency. Because high frequency trades are extremely time-sensitive…

Question

Options

• ATurbo Cores
• BJitter Smoothing
• CPersistent Memory
• DNVMe Drives

• A
  22% (5)
• B
  4% (1)
• C
  65% (15)
• D
  9% (2)

Explanation

There appears to be an error in the provided answer key. B. Jitter Smoothing is the correct answer for this scenario, not C.

Why B is correct: Jitter Smoothing is an HPE iLO 5 Gen 10 feature specifically designed for latency-sensitive workloads like high-frequency trading. It works by suppressing background system activities (timer interrupts, power management tasks, etc.) that cause the unpredictable microsecond-level delays - exactly the "non-deterministic performance" the question describes.

Why the distractors are wrong:

• A. Turbo Cores boost raw processor speed but do not address timing variability or jitter - the problem is unpredictability, not throughput.
• C. Persistent Memory (NVDIMM) improves data persistence and read/write latency for storage tiers, but does not smooth out compute-level timing irregularities.
• D. NVMe Drives reduce storage I/O latency versus SATA/SAS, but again don't target the source of CPU/system-level jitter.

Memory tip: Think "jitter = inconsistency, Jitter Smoothing = consistency." Any time an exam describes unpredictable, non-deterministic latency spikes in a real-time or HFT workload, Jitter Smoothing is the iLO 5 answer - it's the only one in this list built specifically to eliminate timing variability rather than just improve average performance.

Note: You may want to verify the source of this question - the marked answer of C (Persistent Memory) appears to be a typo or error in the answer key.
