Google Professional Cloud Network Engineer Question 318
Select 2Google Cloud PlatformYou are configuring a Google Kubernetes Engine (GKE) cluster for a production environment and need to enable Dataplane V2 for improved performance and security. Which steps must you take to successfully enable Dataplane V2 on your GKE cluster?
- A
Ensure the GKE cluster is running a supported version of GKE (1.18 or later).
- B
Enable Dataplane V2 by setting the --enable-dataplane-v2 flag during cluster creation or upgrade.
- C
Enable network policy enforcement by applying appropriate NetworkPolicy YAML files to the cluster.
- D
Ensure the cluster is configured with VPC-native (alias IP) networking.
- E
Manually download and install Dataplane V2 binaries on each cluster node.
Show answer and explanation
Correct answers: B, D
Explanation
To enable GKE Dataplane V2, you must explicitly enable it using the --enable-dataplane-v2 flag during cluster creation or upgrade, and the cluster must be configured with VPC-native (alias IP) networking. Dataplane V2 enhances network performance and security but does not require manual installation processes or additional tools. Ensuring a supported GKE version (1.20 or later) is necessary but not explicitly stated in this context.
- A. Incorrect.
GKE Dataplane V2 requires a GKE version of 1.20 or later, not 1.18. This option is incorrect.
- B. Correct.
This is correct. You must enable Dataplane V2 explicitly by using the --enable-dataplane-v2 flag during cluster creation or upgrade.
- C. Incorrect.
While network policy enforcement is supported by Dataplane V2, enabling network policies is not a mandatory step for enabling Dataplane V2 itself. This option is incorrect.
- D. Correct.
This is correct. Dataplane V2 requires the cluster to be configured with VPC-native (alias IP) networking.
- E. Incorrect.
This is incorrect. Dataplane V2 is managed by Google Cloud and does not require manual installation of binaries on cluster nodes.
