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
✓
Join the EC2 instance to an Active Directory domain
SAP on Windows requires an Active Directory (AD) domain for Kerberos-based authentication, which is essential for SAP system communication. Before installing SAP software, the EC2 instance must be joined to an AD domain (e.g., via AWS Managed Microsoft AD or self-managed AD). Option A is incorrect because instance type selection should meet SAP requirements, but changing to memory-optimized is not a prerequisite for installation. Option B is incorrect: the instance is already running and stopping/starting does not initialize the OS beyond normal boot. Option C is incorrect: security group rules for SAP ports can be configured at any time before or after installation.
