Q & A

What is the CKA exam and why is it important today?

The CKA (Certified Kubernetes Administrator) exam is a certification for professionals who administer Kubernetes clusters. It's important because Kubernetes is the leading platform for deploying and managing containerized applications in the cloud, as noted in the Linux Foundation's 10th Annual Jobs Report and the 2022 Container Report by Dittadog, which show a significant increase in organizations' use of cloud and container technologies.

What are the three Kubernetes-focused exams mentioned in the script?

The three exams are the CKA (for administrators), the CKAD (Certified Kubernetes Application Developer) for application developers, and the CKS (Certified Kubernetes Security Specialist) for security specialists.

What are the five key domains the CKA exam focuses on?

The CKA exam focuses on cluster architecture, installation, and configuration (25%); workloads and scheduling (15%); services and networking (20%); storage (10%); and troubleshooting (30%).

How many tasks are there in the CKA exam and what is the time limit to complete them?

The CKA exam consists of 15 to 20 performance-based tasks that candidates need to complete within a two-hour time frame.

What is the CKA exam environment like and what is a common mistake candidates make?

The CKA exam environment has six clusters, each with its own set of nodes. Candidates are required to switch contexts between them. A common mistake is performing tasks on the wrong cluster.

Why is it recommended to use the Kubernetes documentation during the exam?

The Kubernetes documentation is allowed during the exam to look up important information. This is because the CKA exam tests practical skills and the ability to get tasks done, not memory skills.

What is the significance of reviewing work after each question in the CKA exam?

Reviewing work after each question ensures that the task was completed correctly. This practice helps avoid spending time on a question only to find out later that it was not done correctly, which could lead to lost marks.

Why is it important to copy and paste during the CKA exam?

Copying and pasting is crucial to avoid typos and errors in object names or details provided in the exam questions. Any mistake in the object name can result in not receiving points for that question.

How should candidates manage their time during the CKA exam?

Candidates should manage their time effectively by attempting all easy questions first, ensuring they are completed correctly, and then moving on to more difficult ones. They should not spend too much time on a single question and should skip back to it if stuck for more than 10 minutes.

What resources are available for CKA exam preparation according to the script?

The script mentions a learning guide on Code Cloud, which includes courses on Linux basics, Docker for beginners, Kubernetes for beginners, CKA exam prep, and an ultimate CKA mock exam series. These resources are designed to help candidates gain the necessary skills and knowledge for the exam.

How long does it typically take to prepare for the CKA exam and what factors affect this duration?

The time it takes to prepare for the CKA exam varies depending on an individual's current skill level and the amount of time they can dedicate daily or weekly. The script provides a chart estimating that preparation could take from one to six months based on different study durations per day.

What is the cost of the CKA exam and how many attempts are allowed?

As of the date of the script, the CKA exam costs $395, and candidates are allowed two attempts.

What is the main goal of preparing for the CKA exam according to the script?

The main goal of preparing for the CKA exam should be to gain knowledge and understanding of Kubernetes concepts. The certification is a byproduct of the learning journey and is most valuable when accompanied by a genuine understanding of the material.
