Question 690
During a high-traffic model-service launch at an online commerce company, engineers report the following issue: A tenant expects exclusive GPU performance from a best-effort time-sliced configuration. The affected work supports product search, recommendations and fraud screening; peak request demand makes degraded predictions visible to customers. Select TWO: the most appropriate action and the strongest verification of that action. (Select TWO.)
Explanation
Correct Answers
Correct corrective action. Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements. This fits the specific reported issue: A tenant expects exclusive GPU performance from a best-effort time-sliced configuration. The corresponding failure being reduced is: A sharing approach that does not meet required isolation or host compatibility can create unpredictable performance or fail to provision guest acceleration.
Correct independent evidence. An authorized VM sees the expected supported accelerator profile and passes workload and isolation tests under simultaneous tenant demand. This verifies the corrective approach for the affected product search, recommendations and fraud screening instead of treating an architecture diagram alone as success.
Incorrect Answers
Not the most direct the action-and-evidence pair for these facts. Use NVIDIA Data Center GPU Manager to collect supported accelerator telemetry, health and diagnostic information across datacenter GPU nodes. This choice concerns nvidia dcgm gpu fleet diagnostics and health and may be valid in another design. But this case reports 'A tenant expects exclusive GPU performance from a best-effort time-sliced configuration', which calls for reasoning about virtual gpus and gpu sharing approaches. The targeted response is: Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.
Not the most direct the action-and-evidence pair for these facts. Choose supported Multi-Instance GPU profiles for multiple smaller workloads requiring hardware-partitioned compute and memory isolation, after verifying GPU and software support. This choice concerns nvidia mig hardware partitioning and isolation and may be valid in another design. But this case reports 'A tenant expects exclusive GPU performance from a best-effort time-sliced configuration', which calls for reasoning about virtual gpus and gpu sharing approaches. The targeted response is: Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.
Not the most direct the action-and-evidence pair for these facts. A sampled node's actual firmware, GPU, driver and fabric settings match the approved inventory or show a tracked exception. This choice concerns cluster inventory firmware and configuration baseline and may be valid in another design. But this case reports 'A tenant expects exclusive GPU performance from a best-effort time-sliced configuration', which calls for reasoning about virtual gpus and gpu sharing approaches. The targeted response is: Compare supported vGPU or time-sliced sharing, passthrough and MIG-backed virtualization according to VM isolation, licensing, performance and hardware support requirements.
