Difficulty: EasyConfigure Azure App Service Plans

An administrator is deploying a web application to Azure App Service. The application must meet the following requirements:
- Use a custom DNS domain name.
- Scale manually up to three instances.

You need to recommend the most cost-effective App Service plan pricing tier that meets the requirements.

Which App Service plan pricing tier should you select?

  1. A
    F1 (Free)
  2. B
    D1 (Shared)
  3. B1 (Basic)Answer
  4. D
    S1 (Standard)

Answer

B1 (Basic)
The B1 (Basic) pricing tier is the most cost-effective tier that supports both custom domains and manual scaling up to three instances. Tiers lower than B1 (such as F1 and D1) do not support scaling, and F1 also lacks custom domain support.

Step-by-Step Solution

1
Identify the minimum pricing tier that supports custom domain names.
The D1 (Shared) tier is the minimum tier that supports custom domains.
The F1 (Free) tier does not support custom domains, so it is eliminated.
2
Identify the minimum pricing tier that supports manual scaling to three instances.
The B1 (Basic) tier is the minimum tier that supports dedicated resources and manual scale-out up to three instances.
The D1 (Shared) tier runs on shared infrastructure and does not support scaling out to multiple instances, so it is eliminated.
3
Compare the remaining tiers (B1 and S1) to find the most cost-effective option.
B1 (Basic) is more cost-effective than S1 (Standard).
Both B1 (Basic) and S1 (Standard) meet the requirements, but B1 (Basic) has a lower monthly cost.
