AZ-104 Question 249
Select 2You are the Azure Administrator for a mission-critical application running on multiple Windows virtual machines behind an Azure Load Balancer. Users report slow response times during peak usage. You suspect CPU or memory bottlenecks. In Azure Monitor, which metrics would be the most relevant to investigate these resource limitations?
- A
Percentage CPU
- B
Available Memory
- C
Operations per Second
- D
Network Bytes Total
Show answer and explanation
Correct answers: A, B
Explanation
To diagnose CPU or memory constraints, focus on metrics that directly measure resource usage. Percentage CPU highlights processor saturation, and Available Memory shows whether virtual machines are under memory pressure. By combining these metrics, you gain clearer insights into potential resource bottlenecks, helping you rule out or confirm CPU or memory overutilization as the main cause of performance issues.
- A. Correct.
Monitoring Percentage CPU helps you understand if the CPU is overutilized during peak loads.
- B. Correct.
Available Memory indicates if the VMs are running low on memory resources, leading to potential performance degradation.
- C. Incorrect.
Operations per Second is typically used for specific workloads (e.g., I/O or storage), but it doesn’t directly indicate CPU or memory pressure.
- D. Incorrect.
Network Bytes Total helps identify traffic levels and potential network constraints, but it is less indicative of CPU or memory bottlenecks.
