Q: Is CCNA worthy of certification?
A: Yes, CCNA certification is worthy because it includes improving your skills and expanding the range of careers you're qualified for. And you will enhance your skills with Cisco networking as well, which will help you in your profession.
Q: Is CCNA a difficult exam?
A: Yes, nothing comes easy, it is a bit difficult for beginners because it tests heavily on the ability to configure Cisco equipment and troubleshoot actual issues that often arise in networking.
Q: Is CCNA a beginner-level course?
A: CCNA is a good certification for beginners that want to pursue a career in IT, computer networking, or cybersecurity. And for the beginners that have the support of an employer should consider using those resources to earn the CCNA.
Q: Does CCNA have coding?
A: No, CCNA is not a programming language it is a Cisco Certified Network-based certification designed for imparting the most basic networking skill. It includes configuration and maintenance of small to medium size Enterprises. There is no programming here.
