- A
Modify the instance type in the AWS Management Console.
Why wrong: Modifying instance type requires instance stop, causing downtime.
- B
Reboot the instance from the AWS Management Console.
Reboot is the fastest recovery without changing the host.
- C
Stop and start the instance from the AWS Management Console.
Why wrong: Stop/start changes the host and takes longer.
- D
Terminate the instance and launch a new one with the same AMI.
Why wrong: Termination loses instance store data and requires reconfiguration.

PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An SAP system administrator needs to restart a critical SAP application server EC2 instance that is part of a cluster. Which approach minimizes 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
✓
Reboot the instance from the AWS Management Console.
Option B is correct because rebooting the instance restarts the operating system without changing the underlying host. The instance retains its public and private IP addresses, elastic network interfaces, and instance store data, minimizing downtime for the SAP application. Modifying the instance type (Option A) requires a stop/start, which moves the instance to a new host and increases downtime. Stopping and starting the instance (Option C) also changes the host and takes longer than a reboot. Terminating the instance and launching a new one (Option D) loses any data on instance store volumes and requires full reconfiguration, causing prolonged downtime.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
