Google Cloud Certified - Professional Cloud Network Engineer Sample Questions:
Your company's current network deployment is composed of a single VPC that is connected to a single data center by a Dedicated Interconnect connection. The Dedicated Interconnect topology has a 99.9% SLA. There is a single VLAN attachment for each of the two Dedicated Interconnect links. All VLAN attachments only use IPv4 addresses. Between the data center and the VPC, only IPv4 routes are exchanged by BGP.
You need to create a solution to exchange IPV6 routes between the data center and the VPC.
You must use a procedure that requires the least amount of setup effort and minimizes costs. It's impossible to add new BGP peers to the configuration of the on-premises routers. Only modifications of the existing BGP peers are possible.
What should you do?
- A. Delete the existing VLAN attachments. Create two new dual stack VLAN attachments. Enable multiprotocol BGP (MP-BGP) on all the BGP sessions between your cloud router and the on- premises router.
- B. Enable BFD on the cloud router where the BGP sessions between your cloud router and the on- premises router are configured.
- C. Modify the stack type of the existing VLAN attachments from IPv4 only to dual stack. Add a pair of new IPv6-only interfaces to the cloud router. Add the new IPv6 BGP peers to the cloud router corresponding to on-premises routers.
- D. Modify the stack type of the existing VLAN attachments from IPv4 only to dual stack. Enable multiprotocol BGP (MP-BGP) on all the BGP sessions between your cloud router and the on- premises router.

You are designing a hub-and-spoke network architecture for your company's cloud-based environment. You need to make sure that all spokes are peered with the hub. The spokes must use the hub's virtual appliance for internet access.
The virtual appliance is configured in high-availability mode with two instances using an internal load balancer with IP address 10.0.0.5. What should you do?
- A. Create two default routes in the hub VPC that point to the next hop instances of the virtual appliances.
Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.
Export the custom routes in the hub. Import the custom routes in the spokes. - B. Create a default route in the hub VPC that points to IP address 10.0.0.5.
Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.
Export the custom routes in the hub.
Import the custom routes in the spokes. - C. Create a default route in the hub VPC that points to IP address 10.0.0.5.
Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.
Create a new route in the spoke VPC that points to IP address 10.0.0.5. - D. Create a default route in the hub VPC that points to IP address 10.0.0.5.
Delete the default internet gateway route in the hub VPC, and create a new higher-priority route that is tagged only to the appliances with a next hop of the default internet gateway.
Export the custom routes in the hub. Import the custom routes in the spokes.
Delete the default internet gateway route of the spokes.
Correct Answer: D 🗳️
Your organization uses Google Cloud's Network Connectivity Center. One of the VPC spokes contains subnet-corp-prod (10.10.1.0/24) and subnet-corp-test (192.168.1.0/24). You need to ensure that only the subnet-corp-prod range is advertised to the Network Connectivity Center hub, even if new subnets are created in the VPC. You want to use the most direct and precise method to control route advertisements from this spoke. What should you do?
- A. Create a custom static route in the Network Connectivity Center hub with the next hop as the VPC spoke for the 10.10.1.0/24 range.
- B. Add 192.168.1.0/24 to the exclude export ranges filter in the VPC spoke configuration.
- C. Set the include export ranges filter to 10.10.1.0/24 in the VPC Spoke configuration, and ensure no other ranges are included.
- D. Create a VPC firewall rule with a DENY action for the 192.168.1.0/24 range.
Correct Answer: C 🗳️
Explanation: Only visible for VCEDumps members. You can sign-up / login (it's free).
You are responsible for designing a new connectivity solution between your organization's on- premises data center and your Google Cloud Virtual Private Cloud (VPC) network. Currently, there is no end-to-end connectivity. You must ensure a service level agreement (SLA) of 99.99% availability. What should you do?
- A. Use one Dedicated Interconnect connection in a single metropolitan area. Configure one Cloud Router and enable global routing in the VPC.
- B. Use a Direct Peering connection between your on-premises data center and Google Cloud.
Configure Classic VPN with two tunnels and one Cloud Router. - C. Use two Dedicated Interconnect connections in a single metropolitan area. Configure one Cloud Router and enable global routing in the VPC.
- D. Use HA VPN. Configure one tunnel from each interface of the VPN gateway to connect to the corresponding interfaces on the peer gateway on-premises. Configure one Cloud Router and enable global routing in the VPC.
Correct Answer: D 🗳️
Explanation: Only visible for VCEDumps members. You can sign-up / login (it's free).
You created a new VPC network named Dev with a single subnet. You added a firewall rule for the network Dev to allow HTTP traffic only and enabled logging. When you try to log in to an instance in the subnet via Remote Desktop Protocol, the login fails. You look for the Firewall rules logs in Stackdriver Logging, but you do not see any entries for blocked traffic. You want to see the logs for blocked traffic.
What should you do?
- A. Create a new firewall rule to allow traffic from port 22, and enable logs.
- B. Create a new firewall rule with priority 65500 to deny all traffic, and enable logs.
- C. Check the VPC flow logs for the instance.
- D. Try connecting to the instance via SSH, and check the logs.
