An organization needs to collect performance data from a legacy application running on a cloud VM. The application does not expose metrics through standard APIs. The team wants to monitor CPU and memory usage without modifying the application code. Which data collection method should they use?

Install a monitoring agent on the VM that collects OS-level metrics.

Use a network packet analyzer to infer performance.

Enable application-level tracing in the code.

Query the cloud provider's billing API for usage data.

A company's cloud application is experiencing intermittent slow responses. The monitoring data shows that CPU usage on the application server is normal, but network latency to the database server spikes during the slow periods. The database server is in a different availability zone. The team has already confirmed that the database is not resource-constrained. Which troubleshooting step should the team take next?

Move the application to a different region.

Increase the database server's CPU quota.

Check for network congestion or packet loss between the application and database servers.

A company is planning to migrate a legacy application to the cloud. The application has unpredictable usage patterns, with occasional spikes that are difficult to forecast. The company wants to minimize costs while ensuring that the application can handle spikes. Which capacity planning strategy is most appropriate?

Use on-demand instances for everything.

Provision for the maximum expected spike at all times.

Use only spot instances to minimize cost.

Use a reserved instance for the base load and auto-scaling for spikes.
