Amazon PAS-C01 Exam - Topic 1 Question 32 Discussion

Actual exam question for Amazon's PAS-C01 exam

Question #: 32
Topic #: 1

A global retail company is running its SAP landscape on AWS Recently the company made changes to its SAP Web Dispatcher architecture The company added an additional SAP Web Dispatcher for high availability with an Application Load Balancer (ALB) to balance the load between the two SAP Web Dispatchers

When users try to access SAP through the ALB the system is reachable However the SAP backend system is showing an error message An investigation reveals that the issue is related to SAP session handling and distribution of requests . The company confirmed that the system was working as expected with one SAP Web Dispatcher. The company replicated the configuration of that SAP Web Dispatcher to the new SAP Web Dispatcher

How can the company resolve the error?

AMaintain persistence by using session cookies Enable session stickiness (session affinity) on the SAP Web Dispatchers by setting the wdisp/HTTP/esid_support parameter to True

BMaintain persistence by using session cookies Enable session stickiness (session affinity) on the ALB

CTurn on host-based routing on the ALB to route traffic between the SAP Web Dispatchers

DTurn on URL-based routing on the ALB to route traffic to the application based on URL

Show Suggested Answer

Suggested Answer: B

Snowball Edge allows for offline data transfer, which is suitable for cases where there is slow and inconsistent internet connectivity. The data can be transferred to the Snowball Edge device, shipped to the AWS region, and then imported into the new SAP HANA system in the VPC. This is a suitable option for migrating large amounts of data from a remote location to AWS.

I’m not sure if session cookies alone will fix this.

Wait, why not just use host-based routing? Seems simpler!

I think it's better to set it on the Web Dispatchers instead.

Sounds like they need to enable session stickiness on the ALB.

I'm leaning towards option B because it makes sense to maintain session persistence at the ALB level, but I'm not entirely confident.

I feel like the wdisp/HTTP/esid_support parameter was mentioned in our notes, but I can't recall if it applies to the ALB or the Web Dispatchers.

I think we practiced a similar question where session affinity was crucial. It seems like the ALB should handle that, right?

I remember we discussed session stickiness in class, but I'm not sure if it should be set on the ALB or the Web Dispatchers.

Okay, I think I've got a strategy. Maintaining session persistence through session cookies and enabling session affinity on the SAP Web Dispatchers seems like the way to go.

Hmm, I'm a bit confused about the session stickiness options. I'll need to review the details on how that works with SAP Web Dispatchers.

The host-based routing and URL-based routing options on the ALB are interesting, but I'm not sure they'll fully address the session handling issue. I'll focus on the session stickiness approach.

I'm a little confused by the wording of this question. Let me re-read the options and see if I can identify the correct implementation specification.

Hmm, I'm not sure about this one. I'll need to review the WebLogic Server architecture and the role of each component to determine the best place to deploy the ODI JEE components.

Hmm, I'm a little confused on this one. Does the main transformer setting make the agent machine only run approved applications? Or does it allow remote access using HDX? I'll have to review my notes to be sure.

Wow, this is a real head-scratcher. I'm torn between options A and B, but I think I'll go with A. Gotta love those SAP Web Dispatcher parameters!

Ah, I see. The company needs to maintain session persistence to ensure the same user is routed to the same SAP Web Dispatcher. Option A looks like the right choice here.
