NEW QUESTION # 83
Your CI/CD pipeline needs to test a new feature before deploying to production. Which of the following Kubernetes features best supports this scenario?

A. Services
B. ConfigMaps
C. Namespaces
D. Secrets
E. Deployments

Answer: C

Explanation:
Namespaces provide isolated environments within a Kubernetes cluster. By creating separate namespaces for development, testing, and production, you can test new features in a controlled environment without impacting production.

NEW QUESTION # 84
You are running a Kubernetes cluster with a single node. You need to ensure that your application remains available even if the node fails. Which Kubernetes feature should you use?

A. Pod Disruption Budgets
B. Horizontal Pod Autoscaling
C. Node affinity
D. High availability
E. Rolling updates

Answer: D

Explanation:
High availability in Kubernetes is achieved by running your cluster on multiple nodes. This ensures that your application remains available even if one node fails, as the workloads can be automatically moved to other healthy nodes.

NEW QUESTION # 85
You have a Kubernetes cluster with multiple nodes, and you want to ensure that traffic is routed to pods based on labels. Which networking feature should you use?

A. Service of type 'LoadBalancer'
B. Pod affinity and anti-affinity
C. NetworkPolicy
D. Service of type 'ClusterlP' with selectors
E. Ingress resource

Answer: D

Explanation:
The correct answer is 'Service of type 'ClusterlP' with selectors'. This approach allows you to define a Service with a 'ClusterlP' and specify a selector that matches pods with specific labels. Kubernetes will then route traffic to pods that have the matching labels. 'NetworkPolicy' is used for network access control, not for load balancing based on labels. 'Service of type 'LoadBalancer" is used for exposing services to the external network. 'Ingress resource' manages external traffic to the cluster 'Pod affinity and anti-affinity' are used for scheduling pods on specific nodes based on labels.

NEW QUESTION # 86
What is the purpose of the "securityContext" field in a pod specification? Choose all that apply.

A. To configure the resource limits for the containers within the pod.
B. To control access to the Kubernetes API server.
C. To define the security context of the pods, such as SELinux and AppArmor.
D. To specify the network namespace that the pod should be created in.
E. To define the user ID and group ID for the containers within the pod.

Answer: C,E

Explanation:
The "securityContext" field in a pod specification is used to define the security context of the containers within the pod. This includes settings related to user ID and group ID, SELinux and AppArmor profiles, and other security-related options. It does not control access to the Kubernetes API server, configure resource limits, or specify the network namespace.
