PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is deploying an SAP BusinessObjects (BO) platform on AWS. To ensure high availability of the BO servers, which AWS service should be used to distribute incoming traffic across multiple BO instances in different Availability Zones?
⚠ Common exam trap
Test-takers frequently confuse DNS-based routing (Route 53) with load balancing, but Route 53 does not provide real-time health-check-based traffic distribution across instances in the same way an ALB does.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Application Load Balancer
The Application Load Balancer (ALB) operates at Layer 7 and can distribute HTTP/HTTPS traffic across multiple SAP BusinessObjects instances in different Availability Zones, providing high availability and health-check-based routing. ALB supports path-based routing and SSL termination, which are essential for modern web applications like SAP BO. It is the correct choice because it is designed for HTTP/HTTPS traffic and can balance load across instances in multiple AZs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
NAT Gateway
Why it's wrong here
NAT Gateway is for outbound internet access, not load balancing.
- ✓
Application Load Balancer
Why this is correct
ALB distributes incoming HTTP/HTTPS traffic across multiple instances.
- ✗
Amazon Route 53
Why it's wrong here
Route 53 provides DNS, not application-level load balancing.
- ✗
Classic Load Balancer
Why it's wrong here
A Classic Load Balancer operates at Layer 4 and does not support the application-layer health checks or path-based routing required for SAP BusinessObjects’ web-tier and processing-server traffic distribution across multiple Availability Zones. It is tempting because it can distribute TCP traffic across EC2 instances, and would be correct for simple HTTP/HTTPS load balancing where only basic connection-level health checks and no application-specific session persistence are needed.

Same concept, more angles
1 more way this is tested on PAS-C01
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. An SAP workload on AWS uses a single Availability Zone deployment. The company wants to improve high availability without changing the existing architecture significantly. Which action should be taken?
easy- A.Use an Amazon EBS volume attached to multiple instances across AZs.
- ✓ B.Add a second SAP application server in a different Availability Zone and configure load balancing.
- C.Increase the size of the EC2 instances to handle failover.
- D.Enable EBS Multi-Attach on the database volume.
Why B: Adding a second SAP application server in a different Availability Zone and configuring load balancing provides high availability by distributing traffic across multiple AZs, ensuring that if one AZ fails, the application remains accessible. This approach aligns with SAP's recommended architecture for multi-AZ deployments without requiring significant changes to the existing single-AZ setup, as it only adds an additional application tier instance and a load balancer.
