Question 678 of 1,733

Operations and Maintenance →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the SAP application is not installed because the UserData script only installs httpd, not the SAP application itself. The CloudFormation template’s UserData section is the only place where software installation is defined, and in this case it configures Apache web server, leaving the SAP application entirely absent from the EC2 instance. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this scenario tests your ability to read CloudFormation templates critically and understand that UserData scripts execute only at launch and must explicitly include all required software. A common trap is assuming that a valid AMI ID or appropriate instance type guarantees the SAP application is present, but the template must contain explicit installation steps. Remember the memory tip: “UserData does what you write, not what you want”—always verify that the script includes the SAP installation commands, not just supporting services like httpd.

PAS-C01 Operations and Maintenance Practice Question

This PAS-C01 practice question tests your understanding of operations and maintenance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.

The operations team deploys the CloudFormation template above. After the stack creation completes, the EC2 instance is launched but the SAP application is not running. What is the most likely reason?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

A
The UserData script only installs httpd, not the SAP application
UserData does not install SAP, so it is not running.
B
The security group does not allow inbound traffic to the SAP application port
Why wrong: The security group is not shown, but the question is about why SAP is not running, not connectivity.
C
The instance type is not suitable for SAP applications
Why wrong: r5.2xlarge is suitable for SAP.
D
The AMI ID is incorrect
Why wrong: No evidence suggests the AMI is incorrect.

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

✓

The UserData script only installs httpd, not the SAP application

The UserData script installs httpd (Apache), not the SAP application. The template does not include any steps to install or start the SAP application. The security group is referenced but not shown; it is likely correct. The instance type is appropriate for SAP. The AMI ID is valid.

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

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.
