Certified Kubernetes Administrator (CKA) Quiz Questions and Answers
Answer :
Choosing cloud-agnostic storage solutions.
Explanation :
In a multi-cloud environment, using cloud-agnostic storage solutions ensures consistent data availability across different cloud platforms without dependency on a specific providers storage features.
The Kubernetes Scheduler determines which nodes are viable for pod placement based on resource availability and scheduling policies, making the final decision on where a pod should run.---
Kubernetes Secrets are specifically designed to store sensitive information securely, such as passwords, OAuth tokens, and SSH keys, preventing them from being exposed in the environment.
For a LoadBalancer type service, the cloud provider provisions a load balancer that forwards external traffic to the NodePorts on the cluster nodes where the service is running.
ReadWriteMany allows multiple nodes to read from and write to the volume, supporting the need for multiple pods in different nodes to access and update shared data consistently.
PVCs reference storage classes for dynamic volume provisioning.
Explanation :
Persistent Volume Claims (PVCs) can reference storage classes to enable dynamic provisioning of Persistent Volumes based on specified storage infrastructure requirements.
Reviewing the ETCD member list helps verify the current members, their status, and the health of each member, which is vital for troubleshooting database failures.---
Recreate Deployment stops old instances before deploying new ones, which is suitable for deployments involving major alterations such as substantial database changes.
Persistent Volumes can be dynamically provisioned using storage classes, which allows for greater flexibility and scalability compared to static hostPath volumes.
Persistent Volumes in Kubernetes are used to persist data even when the pod using it is deleted, ensuring data durability and independence from the pod lifecycle.
