Quick Answer
The correct answer is the Application Load Balancer (ALB) because it operates at Layer 7 of the OSI model, enabling it to intelligently distribute HTTP/HTTPS traffic across multiple SAP BusinessObjects instances deployed in different Availability Zones while performing health checks to ensure only healthy targets receive requests. This makes ALB the ideal choice for SAP BO’s web-based architecture, as it also supports path-based routing and SSL termination, which are critical for modern enterprise deployments. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of high-availability patterns for SAP BusinessObjects on AWS, often appearing as a scenario where you must distinguish between ALB and a Network Load Balancer (NLB). A common trap is choosing NLB because it handles TCP traffic, but SAP BO relies on HTTP/HTTPS, making ALB the correct Layer 7 solution. Memory tip: ALB for App traffic (HTTP/HTTPS) and health checks—think “ALB for BusinessObjects.”
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. 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 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?
NAT Gateway
Why wrong: NAT Gateway is for outbound internet access, not load balancing.
Application Load Balancer
ALB distributes incoming HTTP/HTTPS traffic across multiple instances.
Amazon Route 53
Why wrong: Route 53 provides DNS, not application-level load balancing.
Classic Load Balancer
Why wrong: ALB is more suitable for HTTP/HTTPS than Classic Load Balancer.

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.
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.
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
ALB is more suitable for HTTP/HTTPS than Classic Load Balancer.
Common exam traps
The trap here is that candidates often 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.
Detailed technical explanation
Under the hood, the ALB uses target groups to route requests to registered instances based on health checks and listener rules. For SAP BO, you can configure stickiness (session affinity) using cookies to ensure user sessions remain on the same instance, which is critical for stateful applications. In a real-world scenario, if one AZ fails, the ALB automatically reroutes traffic to healthy instances in other AZs, ensuring minimal downtime.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
