PAS-C01 Design of SAP Workloads on AWS Practice Question
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 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 C is correct because Application Load Balancers support sticky sessions using cookies (either application-generated or AWS-generated). This ensures that a user's requests are sent to the same target group member. Option A is incorrect because path-based routing is for routing requests based on URL path, not for session stickiness. Option B is incorrect because cross-zone load balancing distributes traffic across all zones, but does not ensure stickiness. Option D is incorrect because a Network Load Balancer does not natively support sticky sessions for SAP.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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
Static NAT maps one inside address to one outside address.
✗
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: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PAS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Enable sticky sessions using the ALB-generated cookie. — Option C is correct because Application Load Balancers support sticky sessions using cookies (either application-generated or AWS-generated). This ensures that a user's requests are sent to the same target group member. Option A is incorrect because path-based routing is for routing requests based on URL path, not for session stickiness. Option B is incorrect because cross-zone load balancing distributes traffic across all zones, but does not ensure stickiness. Option D is incorrect because a Network Load Balancer does not natively support sticky sessions for SAP.
What should I do if I get this PAS-C01 question wrong?

What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
