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
✓
Place both the application and database servers in the same Availability Zone
Placing both the SAP application servers and the database in the same Availability Zone (AZ) minimizes network latency by keeping traffic within a single data center. Option A is incorrect because different AZs introduce additional latency due to inter-AZ data transfer. Option C is incorrect because different regions add significant latency and incur higher costs. Option D is incorrect because keeping the database on-premises introduces network latency over the internet or VPN connection.
