Quick Answer
The answer is Amazon Route 53 private hosted zone. This is the correct choice because it provides internal DNS resolution within a VPC, allowing SAP systems to resolve each other’s hostnames without relying on an external DNS service. When migrating an SAP environment to AWS, hostname resolution is critical for SAP application communication, and a private hosted zone integrates directly with the VPC’s DHCP options set to enable this automatically. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how to achieve SAP hostname resolution without DNS in AWS VPC, often appearing as a distractor against VPC peering (which only routes traffic, not DNS), Security Groups (which are stateful firewalls), or Network Load Balancers (which distribute traffic). A common trap is assuming VPC peering alone resolves hostnames, but it does not. Memory tip: Think “Private Zone for Private Names”—Route 53 private hosted zones are the only way to get DNS resolution inside a VPC without external dependencies.
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 environment to AWS and needs to ensure that the SAP systems can communicate with each other using their hostnames without relying on a DNS service. Which AWS feature should be used?
Network Load Balancer (NLB)
Why wrong: NLB distributes traffic, not DNS resolution.
Security Group rules
Why wrong: Security Groups control traffic, not DNS.
VPC Peering
Why wrong: VPC peering connects networks but does not provide DNS resolution.
Amazon Route 53 private hosted zone
Private hosted zones enable DNS resolution within VPCs.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon Route 53 private hosted zone
Amazon Route 53 private hosted zones provide DNS resolution within VPCs. Option A is wrong because VPC peering does not provide DNS. Option C is wrong because Security Groups are firewalls. Option D is wrong because NLB is for load balancing.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
