Google Cloud Professional Cloud Network Engineer — Question 19

You create a Google Kubernetes Engine private cluster and want to use kubectl to get the status of the pods. In one of your instances you notice the master is not responding, even though the cluster is up and running.
What should you do to solve the problem?

Answer options

• A. Assign a public IP address to the instance.
• B. Create a route to reach the Master, pointing to the default internet gateway.
• C. Create the appropriate firewall policy in the VPC to allow traffic from Master node IP address to the instance.
• D. Create the appropriate master authorized network entries to allow the instance to communicate to the master.

Correct answer: D

Explanation

The correct answer is D because creating master authorized network entries allows the specific instance to communicate with the master node. Options A and B do not address the private nature of the cluster, while C may not solve the issue if the master node requires specific authorization settings to communicate effectively.
