Overview -
The following section of the exam is a lab. In this section, you will perform a set of tasks in a live environment. While most functionality will be available to you as it would be in a live environment, some functionality (e.g., copy and paste, ability to navigate to external websites) will not be possible by design.
Scoring is based on the outcome of performing the tasks stated in the lab. In other words, it doesn't matter how you accomplish the task, if you successfully perform it, you will earn credit for that task.
Labs are not timed separately, and this exam may have more than one lab that you must complete. You can use as much time as you would like to complete each lab. But, you should manage your time appropriately to ensure that you are able to complete the lab(s) and all other sections of the exam in the time provided.
Please note that once you submit your work by clicking the Next button within a lab, you will NOT be able to return to the lab.

Agree with Ekramy_Elnaggar. I have tested it in the lab by creating the Function App using App Service Plan (any). I have chosen Free tier plan. ARR Affinity is ON by default which allows sticky sessions. https://azure.github.io/AppService/2016/05/16/Disable-Session-affinity-cookie-(ARR-cookie)-for-Azure-web-apps.html

For testing I have chosen Runtime Stack as '.Net Core' and OS as 'Windows'. 'Consumption' plan don't support ARR Affinity.

Sticky sessions is on by default, so you just need to create a function app in a free App Service plan. Setting can be viewed in configuration->general settings of the function app. Setting name is ARR affinity.

Guys, i don't think we can go with a Free App service Plan here, because the free and shared plans do not support functions. Docs say : "Your function apps can also run on the same dedicated VMs as other App Service apps (Basic, Standard, Premium, and Isolated SKUs)." https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale

this is simply not true.. when you create a function app, you can select the "Free" tier without problem. Then, when you go in to the settings of the function app (running on the free tier), you can see the option for ARR affinity == ON quite clearly. It's under: Configuration -> General Settings -> ARR affinity.. I don't see the issue with free? Am i missing something?

We can go for Free Tier also since session affinity is ON for all tiers as per the below link. https://azure.microsoft.com/en-in/pricing/details/app-service/plans/

Always on / Sticky Session can only be used from APP Service Plan B1. F1 - Free and D1 (basic) don't support Always On. I just tested them all.

it's not about always on, the question is about ARR actually. • Always On: Keeps the app loaded even when there's no traffic. It's required for continuous WebJobs or for WebJobs that are triggered using a CRON expression. • ARR(application request routing) affinity: In a multi-instance deployment, ensure that the client is routed to the same instance for the life of the session. You can set this option to Off for stateless applications.

Not correct. It is turned "On" by default. I just checked in Portal: Created a Func app: Windows > Core .Net > Free Plan Switchted to Blade: Deployment > Settings > Configuration: Value for ARR affinity is "On". Anyway just double check in exam, in case you need to simulate it.

Sticky session is on by default as others mentioned. You just have to create a Function App, select a run time stack (I choose .Net), Hosting plan should be App Service Plan, OS - Linux/Windows, and select the Free plan. I found a free one in Linux and click create.

when u create a function app in shared app service plan it gives a warning " 'AlwaysOn' is not enabled. Your app may not function properly". And 'AlwaysOn' can only be enabled in basic app service plan. so they should not allow the function app to be deployed in free tier at the first place. but I guess to answer this question we are good with the answer displayed.
