PAS-C01 Technology Practice Question
A company is designing a highly available SAP NetWeaver system on AWS. The architecture includes two EC2 instances running the ABAP application server in an Auto Scaling group. Which THREE components are required to maintain session persistence and distribute traffic? (Choose THREE.)
⚠ Common exam trap
Watch out — candidates often confuse infrastructure components (like shared storage or Multi-AZ) with the specific mechanisms that enforce session persistence and traffic distribution, leading them to select options that are important for overall architecture but not directly required for the stated goal.
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
✓
Health checks on the target group to detect unhealthy instances
Health checks on the target group are required to detect unhealthy EC2 instances running the ABAP application server. When an instance fails a health check, the load balancer automatically stops routing traffic to it, ensuring that only healthy instances serve requests. This is critical for maintaining high availability in an SAP NetWeaver environment, as it prevents session failures caused by underlying instance issues.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Health checks on the target group to detect unhealthy instances
Why this is correct
Health checks are essential to route traffic only to healthy instances.
- ✗
A shared file system (e.g., Amazon EFS) for /sapmnt
Why it's wrong here
A shared file system is important for SAP but not for session persistence.
- ✓
An Application Load Balancer (ALB) or Network Load Balancer (NLB)
Why this is correct
A load balancer is needed to distribute incoming requests.
- ✓
Sticky sessions (session affinity) enabled on the load balancer
Why this is correct
Sticky sessions ensure that a user's session is always routed to the same server.
- ✗
A Multi-AZ deployment for the SAP application servers
Why it's wrong here
Multi-AZ is for high availability of the database, not required for session persistence.
