AWS Certified SysOps Administrator – Associate (legacy) — Question 761

A SysOps administrator must monitor a fleet of Amazon EC2 Linux instances with the constraint that no agents be installed. The administrator chooses Amazon
CloudWatch as the monitoring tool.
Which metrics can be measured given the constraints? (Choose three.)

Answer options

• A. CPU Utilization
• B. Disk Read Operations
• C. Memory Utilization
• D. Network Packets In
• E. Network Packets Dropped
• F. CPU Ready Time

Correct answer: A, B, D

Explanation

Amazon CloudWatch provides default, hypervisor-level metrics for Amazon EC2 instances without requiring any guest OS agent, which includes CPU Utilization, Disk Read Operations, and Network Packets In. Memory Utilization is an operating system-level metric that cannot be seen by the hypervisor and requires the Unified CloudWatch Agent to be installed. Network Packets Dropped and CPU Ready Time are not standard metrics provided by Amazon CloudWatch for EC2 instances.
