Short answer in my opinion is, Yes. Because of two main reasons, the first one is the experience you get when you appear for the exam. Most of the certification and any other exams have multiple choice questions where you remember things and choose the correct option in the exam but CKA, CKAD or CKS exams are different. In these exams you actually have to perform tasks on live clusters which, according to us, makes it worth trying out.
The other benefit is, if one has n number of resumes in front of them and they're are trying to hire a Kubernetes developer, there are high chances that they would prefer a resume that has CKA written on it.
