The (CKAD) Certified Kubernetes Application Developer program was created by the Cloud Native Computing Foundation (CNCF), in collaboration with The Linux Foundation
CKAD Certified Kubernetes Application Developer is not an easy exam, the exam has tasks instead of questions like other exams. Questions provide details on what needs to be implemented, candidates are expected to configure it in the provided environment.
A Certified Kubernetes Application Developer can define application resources and use core primitives to build, monitor, and troubleshoot scalable applications and tools in Kubernetes.
The exam assumes working knowledge of container runtimes and microservice architecture.
Candidates should have hands-on experience with Kubenretes.

At the start of each task you’ll be provided with the command to ensure you are on the correct cluster to complete the task.
Nodes making up each cluster can be reached via ssh, using a command such as the following: ssh
You can assume elevated privileges on any node by issuing the following command: sudo -i
You can also use sudo to execute commands with elevated privileges at any time
You must return to the base node (hostname node-1) after completing each task.
Nested−ssh is not supported.
You can use kubectl and the appropriate context to work on any cluster from the base node.
When connected to a cluster member via ssh, you will only be able to work on that particular cluster via kubectl.
For your convenience, all environments, in other words, the base system and the cluster nodes, have the following additional command-line tools pre-installed and * pre-configured:
Further instructions for connecting to cluster nodes will be provided in the appropriate tasks
Where no explicit namespace is specified, the default namespace should be acted upon.
If you need to destroy/recreate a resource to perform a certain task, it is your responsibility to back up the resource definition appropriately prior to destroying * the resource.The CKA & CKAD environments are currently running Kubernetes v1.22.
The CKA, CKS and CKAD exam environment will be aligned with the most recent K8s minor version within approximately 4 to 8 weeks of the K8s release date.
