- A
Use a Network Load Balancer instead of an Application Load Balancer.
Why wrong: NLB does not provide sticky sessions for SAP.
- B
Enable sticky sessions using the ALB-generated cookie.
Sticky sessions ensure user requests go to the same server.
- C
Enable cross-zone load balancing on the ALB.
Why wrong: Cross-zone balancing does not maintain stickiness.
- D
Enable path-based routing to route all requests from a user to the same server.
Why wrong: Path-based routing does not provide session stickiness.
Question 395 of 1,733
Enable ALB Sticky Sessions to Prevent SAP Session Timeouts
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 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?
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
✓
Enable sticky sessions using the ALB-generated cookie.
Option B is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that 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.
Detailed technical explanation
How to think about this question
The ALB-generated cookie (AWSALB) is a stickiness cookie that the ALB inserts into the HTTP response; the client must send it back on subsequent requests for the ALB to route to the same target. The cookie has a configurable duration (default 1 day) and is encrypted with an AWS-managed key. In SAP environments, where application servers maintain user session state in memory, this stickiness is critical to avoid 'session lost' errors, especially when using SAP Web Dispatcher or SAP Fiori.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
