Correct answer & explanation
Rehost on EC2 with AWS Managed Microsoft AD
Option C (Deploy on EC2 with Managed Microsoft AD) is correct because it provides Active Directory without managing domain controllers. Option A (Lift-and-shift to on-premises AD) doesn't reduce overhead. Option B (Use Cognito) is for web identity, not AD. Option D (Deploy on Lightsail) has limited AD support.
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.
