Suggested Answer:
Box 1: No - A PaaS solution does not provide access to the operating system. The Azure Web Apps service provides an environment for you to host your web applications. Behind the scenes, the web apps are hosted on virtual machines running IIS. However, you have no direct access to the virtual machine, the operating system or IIS.
Box 2: Yes -
Box 3: Yes - A PaaS solution that hosts web apps in Azure does provide the ability to scale the platform automatically. This is known as autoscaling. Behind the scenes, the web apps are hosted on virtual machines running IIS. Autoscaling means adding more load balanced virtual machines to host the web apps.

It is NOT the same question.
Q#23/PAGE4: "A Platform as a Service (PaaS) solution provides additional memory to apps by changing pricing tiers." --> ANSWER:NO
Q #31/PAGE7: "A platform as a service (PaaS) solution that hosts web apps in Azure can be provided with additional memory by changing the pricing tier." --> ANSWER: YES
Q#23/PAGE4 Explanation: A Platform as a Service (PaaS) solution does not primarily provide additional memory to apps by changing pricing tiers. While it’s true that higher pricing tiers may offer more resources, including memory, this is not the primary mechanism for providing additional memory to applications. Instead, applications can often be scaled horizontally (adding more instances) or vertically (adding more resources to an existing instance) to meet increased demand. This scaling can often be done without changing the pricing tier.
Q #31/PAGE7 Explanation: In Azure, a PaaS solution that hosts web apps can indeed be provided with additional memory by changing the service plan or pricing tier. However, it’s important to note that this is not the only way to scale resources in a PaaS solution. Applications can also be scaled horizontally or vertically, as mentioned above.
I think MCLC2021 is right, multiple apps could be running within same PAAS via App service plan. Each can use its own memory use, so changing the pricing teir provides memory to the PAAS but not directly to the app. Refer "You can continue to add apps to an existing plan as long as the plan has enough resources to handle the load. However, keep in mind that apps in the same App Service plan all share the same compute resources." https://docs.microsoft.com/en-us/azure/app-service/overview-hosting-plans#what-if-my-app-needs-more-capabilities-or-features
This is totally confusing, Microsoft is mixing the terminology themselves as well: https://docs.microsoft.com/en-us/azure/app-service/app-service-plan-manage
The questions are not the same, read the two questions well. One said 'provides' and the other said 'can be provided'. Understanding of the question is part of the answer.
This question came out during the exam - 13/2/21
Scored 880, this site helped me alot.
But please learn the definitions, acronyms of each feature because not all the questions here will actually be on the test.
Good luck!

On the second and the most discussed question:
In Azure, increasing the memory allocated to a Platform as a Service (PaaS) solution, such as an Azure App Service, is typically not achieved by changing the pricing tier. Pricing tiers for PaaS services like Azure App Service primarily affect the CPU, storage, and other resource allocations, but not the memory.
To adjust the memory allocated to an Azure PaaS service, you typically need to choose a different service plan or instance size within the same pricing tier. Azure App Service plans, for example, come in various sizes, each with a specific combination of CPU, memory, and other resources. By selecting a different service plan or instance size, you can increase or decrease the memory available to your application.
So, while changing the pricing tier can affect the overall performance and resource allocation for a PaaS solution, including CPU and storage, adjusting the memory allocation typically involves selecting the right App Service Plan or instance size within the chosen tier.

See - https://azure.microsoft.com/en-us/pricing/calculator/?service=app-service
Take a look at the Pricing Calculator that is available to everyone. Click on - Compute - App Service then Saved estimates. You will see that by changing tier you get more memory.
The interpretation of statement 2 here depends on the correct definition of Tier. Is a change from B1 to B2 a different tier (no increase in memory)? Or are we talking about B to S change; definitely increases more memory. At least from the pricing table listed in the link it seems to suggest B to S is a change of tier but not B1 to B2.

The reveal answer is correct, check this link out, Scale up & Scale out in Azure App Service -

thank you for providing this link, it provides clarification. I hope for this type of confusing questions we all share resources when available. Sharing opinions or guess without support it's not useful.
This is an "English" question. It's "can be provided" (noting that the ability is there but it's not automatic) vs "provides" (suggesting it happens automatically)
