Difficulty: HardConfigure Azure App Service Plans

You are designing the hosting infrastructure for a critical web application in Azure. The web application has the following requirements:
- Must be able to scale out to 15 instances automatically during peak traffic.
- Must support deployment slots to enable zero-downtime deployments.
- Must support regional virtual network integration.

You need to identify the App Service plan pricing tiers that support all of these requirements.

Which two pricing tiers should you recommend? (Select TWO.)

  1. Premium v2 (P1v2)Answer
  2. Premium v3 (P1v3)Answer
  3. C
    Standard (S1)
  4. D
    Basic (B1)

Answer

Premium v2 (P1v2) and Premium v3 (P1v3) are the correct pricing tiers that meet all requirements.
The correct options are Premium v2 (P1v2) and Premium v3 (P1v3). Premium v2 supports up to 20 scale-out instances, up to 20 deployment slots, and regional virtual network integration. Premium v3 supports up to 30 scale-out instances, up to 20 deployment slots, and regional virtual network integration. Both tiers meet all specified requirements.

Step-by-Step Solution

1
Analyze the scale-out instance requirement.
The application requires scaling out to 15 instances. Basic (B1) supports up to 3 instances (manual only). Standard (S1) supports up to 10 instances. Premium v2 (P1v2) supports up to 20 instances, and Premium v3 (P1v3) supports up to 30 instances.
This requirement eliminates Basic (B1) and Standard (S1) because they do not support scaling to 15 instances.
2
Verify support for deployment slots.
Standard, Premium v2, and Premium v3 tiers support deployment slots (Standard up to 5, Premium up to 20). Basic (B1) does not support deployment slots.
This confirms that Basic (B1) is ineligible.
3
Verify support for regional virtual network integration.
Standard, Premium v2, and Premium v3 tiers all support regional virtual network integration.
All remaining candidate tiers (Standard, Premium v2, Premium v3) satisfy the networking requirement.
4
Select the tiers that satisfy all requirements.
Only Premium v2 (P1v2) and Premium v3 (P1v3) meet all criteria.
Standard (S1) is capped at 10 instances, while Basic (B1) is capped at 3 and has no slot support.
