AWS Monitoring, Logging, and Disaster Recovery 1 — Questions and Answers
Question 1: Which AWS service provides real-time monitoring of AWS resources and applications through metrics, alarms, and dashboards?
- AWS CloudTrail
- Amazon CloudWatch (Correct answer)
- AWS Config
- AWS Trusted Advisor
Correct answer: Amazon CloudWatch
Amazon CloudWatch collects and visualizes metrics, sets alarms, and provides operational insights for AWS resources and applications.
Question 2: What does AWS CloudTrail record?
- CPU and memory metrics of EC2 instances
- API calls and management events made in your AWS account (Correct answer)
- Network packet captures from VPC traffic
- Application log files from EC2 instances
Correct answer: API calls and management events made in your AWS account
AWS CloudTrail logs all API calls and management events, providing an audit trail of actions taken in your AWS account.
Question 3: A company needs an RTO of less than 1 hour and an RPO of less than 15 minutes for their disaster recovery plan. Which DR strategy best meets these requirements at the lowest cost?
- Backup and Restore
- Pilot Light
- Warm Standby (Correct answer)
- Multi-Site Active/Active
Correct answer: Warm Standby
Warm Standby keeps a scaled-down version of the system running, allowing fast failover that meets low RTO/RPO goals more cost-effectively than Multi-Site.
Question 4: Which disaster recovery strategy has the highest RTO and RPO but the lowest cost?
- Pilot Light
- Warm Standby
- Backup and Restore (Correct answer)
- Multi-Site Active/Active
Correct answer: Backup and Restore
Backup and Restore stores data backups that must be fully restored during a disaster, resulting in the highest RTO/RPO but the lowest cost.
Question 5: Which CloudWatch feature allows you to detect anomalous behavior in metrics using machine learning?
- CloudWatch Alarms
- CloudWatch Anomaly Detection (Correct answer)
- CloudWatch Insights
- CloudWatch Synthetics
Correct answer: CloudWatch Anomaly Detection
CloudWatch Anomaly Detection uses ML models to establish a baseline and alerts when metrics deviate significantly from expected patterns.
Question 6: What is the purpose of Amazon CloudWatch Logs Insights?
- To create metric alarms based on log patterns
- To interactively search and analyze log data using query syntax (Correct answer)
- To stream logs to Amazon S3 for archival
- To forward logs to a third-party SIEM tool
Correct answer: To interactively search and analyze log data using query syntax
CloudWatch Logs Insights provides an interactive query interface to search, filter, and analyze log data stored in CloudWatch Logs.
