A cloud administrator notices that a cloud-based application is running slowly. The administrator checks the cloud monitoring dashboard and sees that CPU utilization is at 95% for the application server. Which of the following should the administrator do first?

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Scale out by adding another instance.
The correct first step is to scale out by adding another instance (Option B). CPU utilization at 95% indicates a compute bottleneck. Scaling out distributes the workload across multiple instances, increasing total CPU capacity and reducing pressure on the original server. Adding a network interface (A) addresses network throughput, not CPU. Rebooting (C) provides only temporary relief and does not add capacity. Increasing memory (D) may help if the bottleneck is memory, but the monitoring shows CPU is the issue, so memory increase is not the appropriate first action.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add an additional network interface.
Why it's wrong here
Network bandwidth is not indicated as the problem.
- ✓
Scale out by adding another instance.
Why this is correct
Adding instances distributes the CPU load, alleviating the bottleneck.
- ✗
Reboot the server.
Why it's wrong here
Rebooting provides a temporary fix but does not address the underlying capacity issue.
- ✗
Increase the memory allocation.
Why it's wrong here
Memory increase may not help if CPU is the bottleneck.
