Databricks Certified Data Engineer Professional — Question 125

When evaluating the Ganglia Metrics for a given cluster with 3 executor nodes, which indicator would signal proper utilization of the VM's resources?

Answer options

• A. The five Minute Load Average remains consistent/flat
• B. CPU Utilization is around 75%
• C. Network I/O never spikes
• D. Total Disk Space remains constant

Correct answer: B

Explanation

Option B is correct because a CPU Utilization of around 75% indicates that the VM's processing power is being effectively utilized without being overtaxed. The other options do not directly reflect resource utilization; for instance, a consistent load average or constant disk space does not guarantee that the CPU is being used efficiently.
