Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
No additional configuration is needed.
Private Google Access enables instances without external IPs to reach Google APIs using internal IPs. Once enabled on the subnet, Google automatically adds a private route for the Google API IP ranges, so no further configuration is required. Therefore, option C is correct. Option A is incorrect because a default route to the internet would send traffic to the internet, not to Google APIs via private access. Option B is incorrect because Cloud NAT is not needed and would override private access. Option D is incorrect because instances should not have external IPs if using private access.
