Practice Test 3 | Google Cloud Certified Professional Cloud Network Engineer | Dumps | Mock Test

A firm has one organisation with two projects, one VPC in each, namely VPC-N1, and VPC-N2.

VPC-N1 has two subnets with CIDR 192.168.1.0/24 and 192.168.2.0/24 respectively
VPC-N2 has two subnets with CIDR 10.0.3.0/24 and 10.0.4.0/24 respectively
Both VPCs are peered namely VPCN1-to-VPCN2 (peering from VPC-N1 to VPC-N2) and VPCN2-to-VPCN1 (peering from VPC-N2 to VPC-N1)
Routes have been imported and exported for both networks
VPC-N2 has a Cloud VPN connectivity back to the on-premises network with a CIDR 10.10.0.0/16

In the route table for VPC-N1, what is the next hop for traffic to 10.10.0.0/16?

A. Internet Gateway
B. Vpn-tunnel of 10.10.0.0/16
C. VPCN1-to-VPCN2
D. VPCN2-to-VPCN1

Answer: C

Option A is incorrect, this is the default gateway to the internet (0.0.0.0/0)

Option B is incorrect, VPC-N1 will not have the VPN tunnel as a next hop because it is directly attached to it.

Option C are correct, the next hop to the on-premises network from VPC-N1 is the peering to VPC-N2 which is directly connected to the VPN

Option D is incorrect. The direction of flow is wrong.
