Google PCA Manage and provision cloud infrastructure Practice Question
Which TWO statements are true about Google Cloud VPC networks? (Select exactly 2.)
⚠ Common exam trap
Test-takers frequently confuse VPC scope with subnet scope, assuming VPCs are regional like in AWS, but Google Cloud VPCs are global, and they may also mistakenly believe VPC Peering supports transitive routing, which it explicitly does not.
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
✓
Subnets are regional resources and can span zones.
Google Cloud VPC subnets are regional resources that can span multiple zones within the same region. This allows resources in different zones to use the same subnet without requiring additional routing or VPN configuration, providing high availability and fault tolerance within a region.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Each VPC network is regional in scope.
Why it's wrong here
VPC networks are global, spanning all regions.
- ✗
By default, no firewall rules are created in a new VPC.
Why it's wrong here
Default VPC includes default firewall rules (allow internal, allow SSH, etc.).
- ✓
Subnets are regional resources and can span zones.
Why this is correct
Subnets are regional and each subnet can have IP ranges across zones.
- ✓
VPC Peering allows private RFC 1918 connectivity across VPCs.
Why this is correct
VPC Peering enables private IP connectivity between VPCs.
- ✗
VPC Peering supports transitive routing.
Why it's wrong here
Transitive routing is not supported; peering is non-transitive.
