This PAS-C01 practice question tests your understanding of migration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is migrating its SAP landscape to AWS and wants to use SAP HSR (System Replication) for high availability. Which AWS feature is required to support SAP HSR?
Elastic IP addresses for each instance
Why wrong: Elastic IPs are not required for HSR.
Internet Gateway attached to the VPC
Why wrong: Internet Gateway is for internet access, not required for HSR.
Both instances in the same VPC with private IP connectivity
Low-latency private IP connectivity is required for SAP HSR.
NAT Gateway for outbound traffic
Why wrong: NAT Gateway is not required for HSR.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Both instances in the same VPC with private IP connectivity
SAP HSR requires low-latency connectivity between the primary and secondary instances. Placing them in the same VPC with private IPs meets this requirement. Option A is correct. Option B (Elastic IP) is not necessary. Option C (Internet Gateway) exposes instances to the internet. Option D (NAT Gateway) is for outbound internet.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Elastic IP addresses for each instance
Why it's wrong here
Elastic IPs are not required for HSR.
Internet Gateway attached to the VPC
Why it's wrong here
Internet Gateway is for internet access, not required for HSR.
Both instances in the same VPC with private IP connectivity
Why this is correct
Low-latency private IP connectivity is required for SAP HSR.
Related concept
Static NAT maps one inside address to one outside address.
NAT Gateway for outbound traffic
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.
