A company's cloud environment has a web server that shows a consistent pattern: CPU usage spikes to 100% for 10 minutes every hour, then drops to 20%. Users do not report issues during the spikes. The team is considering whether to optimize. What should they do?

Ignore the pattern because users are not reporting issues.

Increase the VM size to handle the spikes.

Investigate the cause of the periodic spikes to determine if they are expected or a sign of a problem.

Set up an alert to notify the team when CPU exceeds 90%.

A company expects a new marketing campaign to double web traffic in the next month. The current cloud environment handles the existing traffic with 70% CPU usage on the web servers. The company wants to ensure performance during the campaign without over-provisioning long-term. Which capacity planning action should they take?

Reduce the number of web servers to save costs.

Provision additional web servers now and keep them running permanently.

Do nothing and rely on the existing servers to handle the load.

Set up auto-scaling to add web servers as CPU usage increases.

A company's operations team is setting up alerts for a critical application. They want to be notified immediately if the application becomes unavailable, but they do not want to be woken up for minor issues. They also want to track the application's response time over time. Which alerting strategy should they implement?

Set up an alert that triggers only after the application has been down for 30 minutes.

Set up a high-priority alert for service unavailability and a low-priority alert for response time degradation.

Set up an alert for response time only, and manually check availability.

Set up a single alert that triggers on any metric deviation.

A company runs a web application on a cloud VM. The operations team needs to track CPU, memory, and network latency over time and receive notifications when these metrics exceed predefined thresholds. The team wants a single integrated solution that provides historical data and alerting without building custom scripts. Which approach should the team use?

Write a custom script that runs on the VM and emails the operations team when CPU usage is high.

Enable verbose logging on the VM and have the operations team review logs daily.

Use a spreadsheet to manually record performance metrics each day and review them weekly.

Configure the cloud provider's native monitoring service to collect VM metrics and set up alert rules.

A database server in a cloud environment is experiencing slow query responses. The monitoring dashboard shows that CPU utilization is consistently below 30%, but memory utilization is at 95% and the swap file is heavily used. Which metric is most directly indicating the likely bottleneck?
