CV0-003 Question #469: Real Exam Question with Answer & Explanation
The correct answer is D: 9 GPU servers, 10 CPU servers. The new cluster must produce exactly 100 teraflops at 100% utilization, and only the 9 GPU plus 10 CPU configuration reaches that total.
Cloud Architecture and Design
Question
A cloud engineer is upgrading a high-performance computing cluster for the private cloud. The existing cluster is being replaced with GPU servers. A single GPU server is capable of the same teraflops output as 10 CPU servers. The current cluster configuration is as follows: - 100 quad-core CPU servers capable of producing 100 teraflops. - The baseline and current usage is 100%. The new cluster was set up and benchmarked in four different configurations. Which of the following configurations will meet the baseline teraflops performance of the cluster while maintaining the current usage?
Options
- A1 GPU server, 80 CPU servers
- B2 GPU servers, 50 CPU servers
- C5 GPU servers, 40 CPU servers
- D9 GPU servers, 10 CPU servers
Explanation
The new cluster must produce exactly 100 teraflops at 100% utilization, and only the 9 GPU plus 10 CPU configuration reaches that total.
Common mistakes.
- A. One GPU server (10 TF) plus 80 CPU servers (80 TF) yields only 90 teraflops, which is 10 teraflops short of the 100 teraflop baseline requirement.
- B. Two GPU servers (20 TF) plus 50 CPU servers (50 TF) yields only 70 teraflops, falling 30 teraflops below the required baseline.
- C. Five GPU servers (50 TF) plus 40 CPU servers (40 TF) yields only 90 teraflops, still 10 teraflops short of meeting the 100 teraflop baseline.
