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
✓
Elastic Network Adapter (ENA)
(Elastic Network Adapter) is correct. ENA provides higher bandwidth and lower latency for HANA workloads. Option A (NAT Gateway) is incorrect because NAT Gateway adds latency and is used for outbound internet access, not for internal communication within a VPC. Option C (VPC Peering) is incorrect because VPC Peering connects different VPCs, not subnets within the same VPC, and does not reduce latency within a single VPC. Option D (Internet Gateway) is incorrect because it provides internet access and would add latency.
