Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Private Service Connect

    Why it's wrong here

    Private Service Connect allows private access to managed services, but not all Google APIs by default.

  • VPC Service Controls

    Why it's wrong here

    VPC Service Controls provide security perimeters, not connectivity to APIs.

  • Private Google Access

    Why this is correct

    Correct. Private Google Access enables instances without external IPs to reach Google APIs through internal IPs.

  • Cloud NAT

    Why it's wrong here

    Cloud NAT provides outbound internet access but not direct access to Google APIs via private IPs.
