NEW QUESTION # 53
What is the purpose of the 'nodeSelector" field in a Pod's YAML definition?

A. To define the pod's image pull policy (Always, IfNotPresent, Never).
B. To restrict the pod's scheduling to nodes with specific labels.
C. To specify the exact number of replicas for the pod.
D. To specify the pod's termination grace period.
E. To define the pod's restart policy (Always, OnFailure, Never).

NEW QUESTION # 54
Consider the following Kubernetes YAML file representing a deployment:

What is the primary benefit of using a GitOps approach to manage this deployment compared to traditional methods?

A. GitOps provides faster deployment times by eliminating the need for manual interventions.
B. GitOps enhances security by preventing unauthorized changes to the Kubernetes cluster.
C. GitOps enables easy rollbacks to previous deployments by leveraging the versioning capabilities of Git.
D. GitOps automates the deployment process, eliminating the need for human intervention.
E. GitOps simplifies the process of managing complex Kubernetes deployments by providing a centralized repository for configuration.

Answer: C

Explanation:
GitOps leverages Git's version control system, providing a history of changes to your cluster's configuration. This enables easy rollbacks to previous deployments by simply reverting to a specific commit in the Git repository, making it easier to recover from errors or unwanted changes.

NEW QUESTION # 55
You are building a serverless application on Google Cloud Functions that needs to interact with a Google Cloud SQL database. How can you securely connect your Cloud Functions to the Cloud SQL instance?

A. Configure a Cloud SQL proxy service to forward connections to the Cloud SQL instance.
B. Use a dedicated virtual machine (VM) to host a database connector that communicates with both Cloud Functions and Cloud SQL.
C. Use Google Cloud Functions' built-in database connector to access Cloud SQL.
D. Utilize Google Cloud IAM to grant Cloud Functions access to the Cloud SQL instance.
E. Use a service account with appropriate permissions to connect to Cloud SQL from Cloud Functions.

Answer: E

Explanation:
The most secure and recommended approach is to use a service account with appropriate permissions to connect to Cloud SQL from Cloud Functions. This method provides granular control over access and ensures that Cloud Functions only have the necessary permissions to interact with the database. Option A is not a standard feature. Option B is an alternative but adds complexity. Option C introduces extra infrastructure and potential security risks. Option D, while important for overall security, doesnt specifically address database connections.

NEW QUESTION # 56

A. Running all containers with the '-privileged' flag enabled.
B. Deploying all applications in the same namespace.
C. Disabling Kubernetes RBAC and granting full access to all users.
D. Deploying the Kubernetes control plane in a public subnet.
E. Using a network firewall to restrict access to the Kubernetes API server.

Answer: E

Explanation:
Using a network firewall to restrict access to the Kubernetes API server is crucial for protecting your cluster against external threats in a public cloud environment. By limiting access to the API server to authorized users and services, you can significantly reduce the risk of unauthorized access and malicious attacks.
