Google PCA Practice Question: Managing and Provisioning a Solution Infrastructure
A finance company needs to ensure that all compute instances in their VPC can only communicate with Google APIs (e.g., Cloud Storage) over internal IPs. Additionally, instances without external IPs should be able to access the internet for updates. Which TWO configurations should they implement?
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
✓
Configure Cloud NAT
Private Google Access allows VMs to use internal IPs to access Google APIs. Cloud NAT enables outbound internet access for instances without external IPs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure Cloud NAT
Why this is correct
Cloud NAT provides outbound internet access to instances without external IPs.
- ✗
Create a firewall rule allowing egress to 0.0.0.0/0
Why it's wrong here
This allows traffic but doesn't provide NAT; instances without external IPs still can't reach the internet.
- ✓
Enable Private Google Access on the subnet
Why this is correct
This allows VMs to use internal IPs to reach Google APIs.
- ✗
Assign external IPs to all instances
Why it's wrong here
This defeats the purpose of using internal IPs and can be a security risk.
- ✗
Use VPC peering with Google's public network
Why it's wrong here
VPC peering is for connecting VPCs, not for API access.
