Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a placement group to ensure nodes are in close proximity
For SAP HANA multi-node scale-out on AWS, three key network considerations are: using a placement group to ensure all nodes are in close physical proximity (option A), dedicating a separate network interface for HANA inter-node traffic to maximize performance (option B), and ensuring less than 1ms RTT latency between all nodes to meet HANA's strict requirements (option E). Option C (NAT Gateway) is incorrect because NAT Gateways provide outbound internet access, not inter-node connectivity. Option D (public IP addresses) is unnecessary and insecure for inter-node communication; private IPs with placement groups and low latency are sufficient.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use a placement group to ensure nodes are in close proximity
Why this is correct
Placement groups reduce latency between instances.
- ✓
Dedicate a separate network interface for HANA inter-node traffic
Why this is correct
Dedicated interface improves performance and isolation.
- ✗
Use a NAT Gateway for inter-node traffic
Why it's wrong here
NAT Gateway is for outbound internet, not inter-node.
- ✗
Use public IP addresses for inter-node communication
Why it's wrong here
Public IPs are not needed; internal communication uses private IPs.
- ✓
Ensure low latency (less than 1ms RTT) between all nodes
Why this is correct
HANA scale-out requires low latency for performance.
