This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 designing a highly available SAP NetWeaver system on AWS. They plan to use a two-node ASCS/ERS cluster with SUSE Linux Enterprise Server (SLES). Which AWS service is required to manage the virtual IP address for the cluster?
AWS VPC Peering
Why wrong: VPC Peering connects VPCs, not for virtual IP in a cluster.
Amazon Route 53
Route 53 can be configured with DNS failover to route traffic to the active node using the virtual IP.
Amazon EBS
Why wrong: EBS provides block storage, not IP management.
Elastic Load Balancing
Why wrong: ELB is used for load balancing across multiple instances, not for cluster virtual IP management.
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
Amazon Route 53 is required to manage the virtual IP address for the two-node ASCS/ERS cluster by using DNS failover. In a SLES-based SAP NetWeaver cluster on AWS, the cluster software (e.g., Pacemaker) updates a Route 53 DNS record with the private IP address of the active node, enabling clients to connect via a hostname that resolves to the current primary node. This DNS-based approach replaces traditional virtual IP (VIP) floating, which is not natively supported in AWS VPC due to the lack of gratuitous ARP or multicast.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS VPC Peering
Why it's wrong here
VPC Peering connects VPCs, not for virtual IP in a cluster.
Amazon Route 53
Why this is correct
Route 53 can be configured with DNS failover to route traffic to the active node using the virtual IP.

Amazon EBS
Why it's wrong here
EBS provides block storage, not IP management.
Elastic Load Balancing
Why it's wrong here
ELB is used for load balancing across multiple instances, not for cluster virtual IP management.
Common exam traps
The trap here is that candidates often confuse the need for a virtual IP address with traditional network-level VIPs (e.g., using Elastic IP or ENI attachment) and overlook that AWS does not support gratuitous ARP, so DNS-based failover via Route 53 is the required method for SAP ASCS/ERS clusters on SLES.
Detailed technical explanation
Under the hood, the cluster uses the AWS CLI or SDK to update a Route 53 A record via a resource record set with a low TTL (e.g., 60 seconds) to ensure fast failover. The Pacemaker resource agent (e.g., 'aws-vpc-move-ip' or a custom script) triggers the DNS update when the primary node fails, and the secondary node takes over the IP address by updating the same Route 53 record. In a real-world scenario, this approach avoids the need for Elastic IP reassignment, which can be slow and is limited to 5 EIPs per region by default, making Route 53 DNS failover a scalable and cost-effective solution for SAP clusters on AWS.
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.
