PCNE System-generated routes Practice Question

A company is designing a VPC routing strategy. Which three are valid route types in Google Cloud VPC? (Choose three.)

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

System-generated routes

Options A, B, and D are correct. System-generated routes are created automatically for subnet ranges and default internet gateway. Custom static routes are manually defined by administrators. Dynamic routes are learned through BGP from on-premises or other networks. Option C is incorrect because 'VPN tunnel routes' is not a distinct route type; VPN tunnels utilize either static routes or BGP for route advertisement. Option E is incorrect because 'Peering routes' are not a separate type; they are system-generated routes imported from peered VPCs.
