PAS-C01 EC2 Status Checks Practice Question

Network Topology
$ aws ec2 describe-instancesinstance-ids i-0abcdef1234567890query 'Reservations[0].Instances[0].State'$ aws ec2 describe-instance-statusquery 'InstanceStatuses[0].SystemStatus'Refer to the exhibit.```"Code": 16,"Name": "running""Status": "impaired","Details": ["Reachability": "impaired","Description": "AWS is investigating..."

An SAP administrator runs the CLI commands shown in the exhibit for a production EC2 instance. The output indicates that the instance is running but the system status is impaired. Which action should the administrator take to recover the instance?

⚠ Common exam trap

The trap is confusing a stop/start action with EC2 Auto Recovery. Both move the instance to new hardware, but Auto Recovery is automated and triggered by the status check failure, while stop/start is manual and may cause additional downtime.

Answer choices

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

Configure EC2 Auto Recovery and wait for recovery.

EC2 Auto Recovery is the correct action when the system status check fails (impaired) because it automatically recovers the instance by moving it to new hardware while preserving its configuration. Option A (reboot) does not address underlying hardware issues. Option B (restart SAP services) is irrelevant to hardware impairment. Option D (stop and start) does move the instance to new hardware, but it is a manual process and not the recommended automated recovery method. EC2 Auto Recovery is designed specifically for this scenario.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Reboot the instance using the AWS console.

    Why it's wrong here

    Rebooting the instance does not resolve underlying hardware issues; it only restarts the OS.

  • Restart the SAP application services.

    Why it's wrong here

    Restarting SAP application services addresses application-level issues, not hardware impairment.

  • Configure EC2 Auto Recovery and wait for recovery.

    Why this is correct

    EC2 Auto Recovery is the correct automated method to recover from a system status impairment, moving the instance to healthy hardware.

  • Stop and start the instance.

    Why it's wrong here

    Stop and start does move the instance to new hardware, but it is a manual action and not the automated recovery that EC2 Auto Recovery provides.
