A private GKE cluster has a private control plane endpoint. Pods need to resolve internal DNS names from a private Cloud DNS zone. The cluster is configured with the default kube-dns. What should you configure to ensure Pods can resolve the private zone?

Use the DNS-based endpoint to access the control plane.

Configure the nodes to use the Cloud DNS server as the upstream DNS.

Enable Cloud DNS integration on the cluster and configure the private zone as a stub domain.

Create a NetworkPolicy that allows egress to the DNS server.

What is the purpose of NodeLocal DNSCache in GKE?

To provide a DNS service for external domains

To cache DNS responses locally on each node to reduce latency and load on the DNS service

To replace the need for Cloud DNS

To provide DNS resolution for Services

What is a benefit of using GKE Dataplane V2?

It eliminates the need for a VPC network

It provides a built-in load balancer for Services

It automatically enables private clusters

Improved performance and scalability for network policies

What is the default behavior of source NAT (SNAT) for outbound traffic from GKE Pods?

Pods use the cluster's service IP as the source IP

Pods use a random IP address as the source IP

Pods use the node's IP address as the source IP

Pods use their own IP address as the source IP

When creating a GKE cluster, what are the primary and secondary IP ranges used for?

Primary for nodes and Pods, secondary for Services

Primary for Pods, secondary for nodes and Services

Primary for Services, secondary for nodes and Pods

Primary for nodes, secondary for Pods and Services
