Question 76
You need to configure a Google Kubernetes Engine (GKE) cluster. The initial deployment should have 5 nodes with the potential to scale to 10 nodes. The maximum number of Pods per node is 8. The number of services could grow from 100 to up to 1024. How should you design the IP schema to optimally meet this requirement?
Question 77
You need to create a GKE cluster in an existing VPC that is accessible from on-premises. You must meet the following requirements:
IP ranges for pods and services must be as small as possible.
The nodes and the master must not be reachable from the internet.
You must be able to use kubectl commands from on-premises subnets to manage the cluster.

Question 79
You have an application hosted on a Compute Engine virtual machine instance that cannot communicate with a resource outside of its subnet. When you review the flow and firewall logs, you do not see any denied traffic listed.
During troubleshooting you find:
* Flow logs are enabled for the VPC subnet, and all firewall rules are set to log.
* The subnetwork logs are not excluded from Stackdriver.
* The instance that is hosting the application can communicate outside the subnet.
* Other instances within the subnet can communicate outside the subnet.
* The external resource initiates communication.
What is the most likely cause of the missing log lines?

Question 80
You are configuring a new HTTP application that will be exposed externally behind both IPv4 and IPv6 virtual IP addresses, using ports 80, 8080, and 443. You will have backends in two regions: us-west1 and us-east1. You want to serve the content with the lowest-possible latency while ensuring high availability and autoscaling, and create native content-based rules using the HTTP hostname and request path. The IP addresses of the clients that connect to the load balancer need to be visible to the backends. Which configuration should you use?
