What should you do?

Answer Options
Correct Answer: A
Question 2

You have a Cloud Storage bucket in Google Cloud project XYZ. The bucket contains sensitive data. You need to design a solution to ensure that only instances belonging to VPCs under project XYZ can access the data stored in this Cloud Storage bucket. What should you do?

Answer Options
Correct Answer: C
Question 3

You need to define an address plan for a future new Google Kubernetes Engine (GKE) cluster in your Virtual Private Cloud (VPC). This will be a VPC-native cluster, and the default Pod IP range allocation will be used. You must pre-provision all the needed VPC subnets and their respective IP address ranges before cluster creation. The cluster will initially have a single node, but it will be scaled to a maximum of three nodes if necessary. You want to allocate the minimum number of Pod IP addresses. Which subnet mask should you use for the Pod IP address range?

Answer Options
Correct Answer: A
Question 4

You want to apply a new Cloud Armor policy to an application that is deployed in Google Kubernetes Engine (GKE). You want to find out which target to use for your Cloud Armor policy.

Which GKE resource should you use?

Answer Options
Correct Answer: D
Explanation

Cloud Armour is applied at load balancers Configuring Google Cloud Armor through Ingress. https://cloud.google.com/kubernetes-engine/docs/how-to/ingress-features Security policy features Google Cloud Armor security policies have the following core features: You can optionally use the QUIC protocol with load balancers that use Google Cloud Armor. You can use Google Cloud Armor with external HTTP(S) load balancers that are in either Premium Tier or Standard Tier. You can use security policies with GKE and the default Ingress controller.

Question 5

You are deploying GKE clusters in your organization's Google Cloud environment. The pods in these clusters need to egress directly to the internet for a majority of their communications. You need to deploy the clusters and associated networking features using the most cost-efficient approach, and following Google-recommended practices. What should you do?

Answer Options
Correct Answer: A
Explanation

For GKE pods that need to egress directly to the internet for most of their communications, the most cost-efficient and straightforward approach is to deploy a GKE cluster with public cluster nodes. Public nodes have external IP addresses, allowing pods to directly reach the internet. This eliminates the need for additional services like Cloud NAT or Secure Web Proxy for outbound internet access, which would incur extra costs and management overhead.

Exact Extract:

'Public clusters have nodes with external IP addresses, allowing them to directly initiate connections to the internet. This is the simplest configuration for clusters that require direct internet egress for their workloads.'

'When using public clusters, Cloud NAT is not required for outbound internet connectivity from the nodes or pods, as they can use their external IP addresses. This can reduce operational overhead and cost compared to private clusters that need NAT.'Reference: Google Kubernetes Engine Documentation - Cluster network configuration, Public clusters vs Private clusters
