You have SQL Server 2019 or an Azure virtual machine that runs Windows Server 2019. The virtual machine has 4 vCPUs and 28 GB of memory.
Vou scale up the virtual machine to 8 vCPUs and 64 GB of memory.
You need to reduce tempdb contention without regatively affecting server performance.
What is the number of secondary data files that you should configure for tempdb?
Correct Answer: C
Basic Concept: This question tests Azure monitoring and performance management, including which metric, log destination, or alerting behavior fits the operational requirement.
Why C is Correct: 8 is related to operational monitoring or tuning, but it must match the exact signal needed:
query history, resource utilization, wait/blocking detail, or automatic remediation. This fits the case because the requested outcome is: You need to reduce tempdb contention without regatively affecting server performance. The selected feature addresses that outcome directly rather than relying on a workaround.
Why A is Wrong: 2 is related to operational monitoring or tuning, but it must match the exact signal needed:
query history, resource utilization, wait/blocking detail, or automatic remediation. It does not expose the required metric, query history, wait/blocking signal, or tuning mechanism; using it would not give the administrator the evidence requested.
Why B is Wrong: 4 is related to operational monitoring or tuning, but it must match the exact signal needed:
query history, resource utilization, wait/blocking detail, or automatic remediation. It is useful in other troubleshooting paths, but this scenario requires a more specific monitoring or optimization feature.
Why D is Wrong: 64 is related to operational monitoring or tuning, but it must match the exact signal needed:
query history, resource utilization, wait/blocking detail, or automatic remediation. It does not expose the required metric, query history, wait/blocking signal, or tuning mechanism; using it would not give the administrator the evidence requested.
