Quick Answer
The correct answer is to create a private hosted zone in Amazon Route 53 with an A record. This configuration allows you to map the SAP application server’s hostname to the private IP address of the EC2 instance within your VPC, ensuring that DNS resolution consistently returns that IP even if the underlying instance is replaced or restarted. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of how to retain SAP hostnames after AWS migration using Route 53 private hosted zone, a critical requirement because SAP systems often hardcode hostnames in profiles and kernel parameters. A common trap is assuming a public hosted zone or Elastic IP is needed, but the key insight is that SAP application servers communicate internally, so a private zone with a simple A record is sufficient and avoids public exposure. Memory tip: think “Private A for SAP” — private zone, A record, for the application server’s internal identity.
This PAS-C01 practice question tests your understanding of migration. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 an SAP system to AWS and needs to retain the same hostname for the SAP application server after migration. Which configuration should the company use?
Assign an Elastic IP to the EC2 instance and update the /etc/hosts file
Why wrong: Hostname not resolved via DNS.
Create a private hosted zone in Amazon Route 53 with an A record
Provides internal DNS resolution within VPC.
Create a CNAME record in a public hosted zone pointing to the EC2 instance
Why wrong: Public DNS, not private.
Use a public hosted zone in Route 53 with an A record
Why wrong: Public DNS, not private.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create a private hosted zone in Amazon Route 53 with an A record
Option B is correct because a private hosted zone in Amazon Route 53 allows you to create an A record that maps a custom hostname to the private IP address of an EC2 instance. This ensures that the SAP application server retains the same hostname after migration, as DNS resolution within the VPC will consistently return the instance's private IP, regardless of instance changes or restarts.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Create a CNAME record in a public hosted zone pointing to the EC2 instance
Why it's wrong here
Public DNS, not private.
Use a public hosted zone in Route 53 with an A record
Why it's wrong here
Public DNS, not private.
Common exam traps
The trap here is that candidates often confuse Elastic IPs with hostname persistence, assuming a static public IP is sufficient, but SAP systems rely on internal hostname resolution via DNS or /etc/hosts, not public IPs, and a private hosted zone provides the necessary centralized, scalable DNS solution within the VPC.
Detailed technical explanation
Under the hood, a private hosted zone in Route 53 is associated with a VPC and provides DNS resolution for resources within that VPC without exposing them to the internet. The A record in the private zone maps the desired hostname to the EC2 instance's private IP, which is stable and does not change when the instance is stopped and started, unlike public IPs. In a real-world SAP migration, this approach ensures that dependent systems and SAP profiles referencing the hostname continue to function without reconfiguration, as DNS queries from within the VPC resolve to the correct private IP.
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.
