Quick Answer
The answer is to join the Windows EC2 instance to an Active Directory domain. This step is required because SAP on Windows relies on Kerberos authentication, which necessitates a domain environment—either a managed Active Directory or a self-managed domain controller—to function correctly for user logins and service accounts. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of the foundational prerequisites for SAP workloads on Windows, often appearing as a trap where candidates assume a running instance is ready for SAP installation. A common mistake is overlooking that SAP components like the ABAP dispatcher or SAP Host Agent will fail without domain membership, even if the instance is properly sized and networked. Remember the mnemonic: "SAP on Windows needs a domain to reign."
This PAS-C01 practice question tests your understanding of migration. 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.
Refer to the exhibit. A company is migrating an SAP application server running on Windows to AWS. They launched an EC2 instance with Windows Server. After launching, they run the command and get the output shown. They need to install SAP software. What additional step is required before installing SAP?
Change the instance type to a memory-optimized instance
Why wrong: Not required before installation.
Stop and start the instance to initialize the Windows OS
Why wrong: Instance is already running.
Modify the security group to allow SAP-specific ports
Why wrong: Can be done after installation.
Join the EC2 instance to an Active Directory domain
SAP on Windows typically requires domain membership.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Join the EC2 instance to an Active Directory domain
Option A is correct because SAP on Windows requires joining a domain (or using a local domain) for Kerberos authentication. Option B is incorrect because the instance is already running. Option C is incorrect because SAP installation does not require a specific instance type beyond requirements. Option D is incorrect because the security group can be modified anytime.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
