Quick Answer
The correct choice is the Application Load Balancer because it operates at Layer 7, allowing it to intelligently route HTTP and HTTPS traffic based on request content, which is essential for a high availability SAP BusinessObjects web tier. Unlike a Network Load Balancer, which works at Layer 4 and cannot inspect application-level data, the ALB can perform path-based routing and SSL termination, making it ideal for distributing user requests across multiple web servers while maintaining a single DNS name. On the AWS Certified SAP on Specialty PAS-C01 exam, this question tests your understanding of how to achieve web-tier resilience for SAP BusinessObjects, often presenting CloudFront as a distractor—remember that CloudFront is a CDN, not a load balancer, and Route 53 weighted routing lacks integrated health checks. A quick memory tip: for web apps, think “Layer 7 ALB” because it speaks the same language as your HTTP traffic.
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 an SAP BusinessObjects environment to AWS. They need to ensure high availability for the web tier and have a requirement to use a single DNS name for end users. Which AWS service should they use to distribute traffic across multiple web servers?
Amazon CloudFront
Why wrong: CDN, not a load balancer.
Network Load Balancer
Why wrong: Operates at Layer 4, not ideal for web traffic.
Amazon Route 53 weighted routing policy
Why wrong: DNS-level routing without health checks.
Application Load Balancer
Layer 7 load balancer suitable for HTTP/HTTPS.
Answer choices
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
Application Load Balancer operates at Layer 7 and can distribute HTTP/HTTPS traffic. Option A (NLB) is Layer 4, not ideal for web applications. Option B (CloudFront) is a CDN, not a load balancer. Option D (Route 53 weighted routing) distributes traffic but does not provide health checks like a load balancer.
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 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.
