In the GCP Console, what should you do?


A. Assign a public IP address to the instance.
B. Assign a new reserved internal IP address to the instance.
C. Change the instance’s current internal IP address to static.
D. Add custom metadata to the instance with key internal-address and value reserved.

Google Professional-Cloud-Network-Engineer Sample Question 2

Your company has just launched a new critical revenue-generating web application. You deployed the application for scalability using managed instance groups, autoscaling, and a network load balancer as frontend. One day, you notice severe bursty traffic that the caused autoscaling to reach the maximum number of instances, and users of your application cannot complete transactions. After an investigation, you think it as a DDOS attack. You want to quickly restore user access to your application and allow successful transactions while minimizing cost.

Which two steps should you take? (Choose two.)


A. Use Cloud Armor to blacklist the attacker’s IP addresses.
B. Increase the maximum autoscaling backend to accommodate the severe bursty traffic.
C. Create a global HTTP(s) load balancer and move your application backend to this load balancer.
D. Shut down the entire application in GCP for a few hours. The attack will stop when the application is offline.
E. SSH into the backend compute engine instances, and view the auth logs and syslogs to further understand the nature of the attack.

Google Professional-Cloud-Network-Engineer Sample Question 4

Your on-premises data center has 2 routers connected to your GCP through a VPN on each router. All applications are working correctly; however, all of the traffic is passing across a single VPN instead of being load-balanced across the 2 connections as desired.

During troubleshooting you find:

•Each on-premises router is configured with the same ASN.

•Each on-premises router is configured with the same routes and priorities.

•Both on-premises routers are configured with a VPN connected to a single Cloud Router.

•The VPN logs have no-proposal-chosen lines when the VPNs are connecting.

•BGP session is not established between one on-premises router and the Cloud Router.

What is the most likely cause of this problem?


A. One of the VPN sessions is configured incorrectly.
B. A firewall is blocking the traffic across the second VPN connection.
C. You do not have a load balancer to load-balance the network traffic.
D. BGP sessions are not established between both on-premises routers and the Cloud Router.

Answer: A Explanation: Explanation: If the VPN logs show a no-proposal-chosen error, this error indicates that Cloud VPN and your peer VPN gateway were unable to agree on a set of ciphers. For IKEv1, the set of ciphers must match exactly. For IKEv2, there must be at least one common cipher proposed by each gateway. Make sure that you use supported ciphers to configure your peer VPN gateway.,of%20ciphers%20must%20match%20exactly. &text=Make%20sure%20that%20you%20use,configure%20your%20peer%20VPN%20gateway.
