Question 41

You want to configure load balancing for an internet-facing, standard voice-over-IP (VOIP) application. Which type of load balancer should you use?

  1. HTTP(S) load balancer
  2. Network load balancer
  3. Internal TCP/UDP load balancer
  4. TCP/SSL proxy load balancer

Question 42

You want to configure a NAT to perform address translation between your on-premises network blocks and GCP. Which NAT solution should you use?

  1. Cloud NAT
  2. An instance with IP forwarding enabled
  3. An instance configured with iptables DNAT rules
  4. An instance configured with iptables SNAT rules

Question 43

You need to ensure your personal SSH key works on every instance in your project. You want to accomplish this as efficiently as possible. What should you do?

  1. Upload your public ssh key to the project Metadata.
  2. Upload your public ssh key to each instance Metadata.
  3. Create a custom Google Compute Engine image with your public ssh key embedded.
  4. Use gcloud compute ssh to automatically copy your public ssh key to the instance.

Question 44

In order to provide subnet level isolation, you want to force instance-A in one subnet to route through a security appliance, called instance-B, in another subnet. What should you do?

  1. Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with no tag.
  2. Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with a tag applied to instance-A.
  3. Delete the system-generated subnet route and create a specific route to instance-B with a tag applied to instance-A.
  4. Move instance-B to another VPC and, using multi-NIC, connect instance-B's interface to instance-A's network. Configure the appropriate routes to force traffic through to instance-A.

Question 45

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?

  1. Assign a public IP address to the instance.
  2. Create a route to reach the Master, pointing to the default internet gateway.
  3. Create the appropriate firewall policy in the VPC to allow traffic from Master node IP address to the instance.
  4. Create the appropriate master authorized network entries to allow the instance to communicate to the master.
