A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

2-2Securing communications and establishing boundary protection

An engineer notices that a workload inside a service perimeter still reaches a third-party SaaS API on the public internet. Why does the perimeter not stop it?

The call left through a Cloud NAT gateway in the VPCThe path a packet takes is not what the perimeter reasons about.
Egress rules permit that destination by defaultEgress rules widen access to Google Cloud services, not to outside ones.
The API had been added to an access levelAccess levels admit callers inward rather than exempting destinations.
Perimeters govern Google Cloud managed services onlyCorrect · your answerCorrect. Anything else is out of scope.

Correct.

Concept

A boundary is defined by the set of things it can see. A control wired into one provider's service front door has no reach over calls to anyone else's, whatever the network path looks like.

Why D

A service perimeter works specifically with Google Cloud managed services and does not block access to any third-party APIs or services on the internet.

Source

A service perimeter allows free communication within the perimeter but, by default, blocks communication to Google Cloud services across the perimeter. The perimeter works specifically with Google Cloud managed services. The perimeter doesn't block access to any third-party APIs or services on the internet.
