PAS-C01 Operations and Maintenance Practice Question

This PAS-C01 practice question tests your understanding of operations and maintenance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.

A company runs SAP on AWS and uses a distributed deployment with multiple application servers in an Auto Scaling group. They want to ensure that when a new instance is launched, it is automatically registered with the SAP Central Services instance. Which approach should they use?

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

Use an Auto Scaling lifecycle hook that triggers a Lambda function to perform the registration when the instance enters the 'InService' state.

Option C is correct because using a lifecycle hook with a custom Lambda function allows running custom actions at instance launch, such as registration with Central Services. Option A is wrong because user data runs at boot but does not wait for the instance to be fully ready for service registration. Option B is wrong because CloudFormation is for stack creation, not for ongoing Auto Scaling events. Option D is wrong because SSM Run Command is manual or scheduled, not automated at launch.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

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

  • Configure the user data script to run the registration command on instance boot.

    Why it's wrong here

    User data runs only at first boot; if the instance is replaced, it runs again, but there is no guarantee of order relative to Auto Scaling.

  • Use an AWS CloudFormation template to create the instance and include the registration in the template.

    Why it's wrong here

    CloudFormation is not designed to handle dynamic scaling events.

  • Use AWS Systems Manager Run Command to register the instance after it launches.

    Why it's wrong here

    Run Command requires manual or scheduled execution, not automatic at launch.

  • Use an Auto Scaling lifecycle hook that triggers a Lambda function to perform the registration when the instance enters the 'InService' state.

    Why this is correct

    Lifecycle hooks can pause instance launch and run custom actions before the instance is fully in service.

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.

Trap categories for this question

  • Command / output trap

    Run Command requires manual or scheduled execution, not automatic at launch.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
