Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A VPC accessible service configuration
Why this is correct
This configuration specifies which VPCs (and their subnets) are allowed to access the protected APIs. It is a key part of the perimeter.
- ✗
A VPC network with Private Google Access enabled
Why it's wrong here
Private Google Access is not required for VPC Service Controls; it's a separate feature.
- ✗
An access level
Why it's wrong here
Access levels are optional controls based on IP address, device, etc. They are not required to create a perimeter.
- ✗
A list of allowed APIs (restricted services)
Why it's wrong here
The perimeter restricts all APIs by default; you do not need to list allowed APIs. Instead, you may list restricted services.
- ✓
A set of projects to protect
Why this is correct
The perimeter must specify which projects (the protected ones) have their APIs restricted.
