PAS-C01 Design of SAP Workloads on AWS Practice Question
A company is running SAP Business Suite on AWS. The SAP application servers are behind an Application Load Balancer (ALB). Users are experiencing session timeouts because the ALB is distributing requests to different application servers. What should the company configure on the ALB to maintain session stickiness?
⚠ Common exam trap
Candidates often confuse cross-zone load balancing (which improves availability) with session stickiness, or they incorrectly assume that an NLB can provide the same cookie-based stickiness as an ALB, leading them to choose Option A or C instead of the correct sticky sessions configuration.

Correct answer & explanation
✓
Enable sticky sessions using the ALB-generated cookie.
Enabling sticky sessions (session affinity) on an Application Load Balancer using the ALB-generated cookie (AWSALB) ensures that all requests from a user session are routed to the same target (SAP application server). This prevents session timeouts caused by requests being distributed to different servers, which would lose in-memory session state. The ALB-generated cookie is the simplest and most appropriate method for SAP Business Suite, as it does not require custom application code.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a Network Load Balancer instead of an Application Load Balancer.
Why it's wrong here
NLB does not provide sticky sessions for SAP.
- ✓
Enable sticky sessions using the ALB-generated cookie.
Why this is correct
Sticky sessions ensure user requests go to the same server.
- ✗
Enable cross-zone load balancing on the ALB.
Why it's wrong here
Cross-zone balancing does not maintain stickiness.
- ✗
Enable path-based routing to route all requests from a user to the same server.
Why it's wrong here
Path-based routing does not provide session stickiness.
