Google Cloud Certified - Professional Cloud Network Engineer Questions and Answers

Question 1

You’ve received reports of latency between two application VMs which run in two different regions of your Google Cloud VPC network. There is typically about 8ms of latency, but now there is approximately 17ms of latency. You've eliminated application issues as a root cause, and you suspect that the latency may be a Google Cloud platform issue. You need to confirm this hypothesis using Google-recommended practices. What should you do?

Options:

A.

Q Use Network Intelligence Center Performance Dashboard to view the inter-region packet loss for your VPC.

B.

O Install and run tcpdump on both instances, and calculate the latency between the two instances by comparing the timestamps in the packet captures.

C.

Q Use Network Intelligence Center Performance Dashboard to view inter-region latency for the Google Cloud network.

D.

Q Use Network Intelligence Center Connectivity Tests, run a test between the two VMs, and review the inter-region latency in the test results.

Question 2

All the instances in your project are configured with the custom metadata enable-oslogin value set to FALSE and to block project-wide SSH keys. None of the instances are set with any SSH key, and no project-wide SSH keys have been configured. Firewall rules are set up to allow SSH sessions from any IP address range. You want to SSH into one instance.

What should you do?

Options:

A.

Open the Cloud Shell SSH into the instance using gcloud compute ssh.

B.

Set the custom metadata enable-oslogin to TRUE, and SSH into the instance using a third-party tool like putty or ssh.

C.

Generate a new SSH key pair. Verify the format of the private key and add it to the instance. SSH into the instance using a third-party tool like putty or ssh.

D.

Generate a new SSH key pair. Verify the format of the public key and add it to the project. SSH into the instance using a third-party tool like putty or ssh.

Question 3

Your end users are located in close proximity to us-east1 and europe-west1. Their workloads need to communicate with each other. You want to minimize cost and increase network efficiency.

How should you design this topology?

Options:

A.

Create 2 VPCs, each with their own regions and individual subnets. Create 2 VPN gateways to establish connectivity between these regions.

B.

Create 2 VPCs, each with their own region and individual subnets. Use external IP addresses on the instances to establish connectivity between these regions.

C.

Create 1 VPC with 2 regional subnets. Create a global load balancer to establish connectivity between the regions.

D.

Create 1 VPC with 2 regional subnets. Deploy workloads in these subnets and have them communicate using private RFC1918 IP addresses.
