CCNA Scope

If you're an enthusiast looking for a career in cybersecurity, I believe that you should start by researching about the basic uses and applications of cyber security, follow it up with the function, purpose and perspectives it has in today generation. The skill set is rather vast and demanding for advanced technologies like cyber security and, to become an expert in this field, you will need to master the technical skills like networking, computer programming and such, do not forget, you will also be required to have adequate soft skills such as verbal communication, written communication and presentation skills to expose your work effectively. One way to look at the growth in the field of cyber security is from a learner's point of view. Through security certifications. There are a multitude of certifications based on the category or field of security. Here are a few to name:
Beginner level:
Certified Ethical Hacker - CEH | EC-Council, provided by EC-Council
CompTIA Security+ Provided by CompTIA
Medium to Advanced Levels:
Offensive Security Certified Professional - Provided by Offensive Security. CompTIA CSA+ Provided by CompTIA CyberSecurity Analyst
Similarly, there's CHFI - Computer Hacking Forensic Investigator Certification [Computer Hacking Forensic Investigator-CHFI | EC-Council] for Candidates interested in Forensics - Provided by EC-Council among many more.
2. The next approach is through attending and trying out CTF events - All about CTF (Capture The Flag). These are the perfect platforms to prove your strength and show your skills in the field of cybersecurity. People learn about computer security in a number of ways, all important. For the sake of argument, let's put these in three categories: reading, building, and doing. [Why Should I Play Capture-the-Flag? ]
A Cyber Capture the Flag exercise typically resides in the last of these three categories: DOING. CTF attempts to model the defend/attack experience. Time pressures bring into sharp focus theoretical lessons. Competitive forces expose assumptions and flaws in tools and systems constructed in a vacuum.
3. Bug Bounty programme
A bug bounty programme, also called a vulnerability rewards programme (VRP), is a crowdsourcing initiative that rewards individuals for discovering and reporting software bugs. If finding vulnerabilities is your forte, these are for you. Here's one of the sample available list of bug bounty programs: Bug Bounty List | Bugcrowd.

The scope of CCNA R&S Course in India is dependent upon the track of CCNA Cert you choose. The scope of CCNA certification is quite more than that of CCNA R&S as the security of data is the most important concern for every organization. However, there is not much scope for other CCNA tracks such as Wireless, Cloud etc. in India. However, even if you want to prepare for any Cisco certification like CCNA Security or CCNP or CCNP Security, you will anyhow have to prepare for CCNA first. So CCNA is pre-requisite for all other Cisco courses.
Well coming up to developers, it depends, what kind of Project is the Developer working on, or what he/she aspires for the Future. Having an additional qualification never hurts, only helps at times.
AFAIK, Software Engineers are recruited in major IT MNCs based on their Analytical Ability, Problem-Solving Tactics, knowledge of various Programming Tools & Technologies, Platforms, Debugging etc. skills. I'm not sure where CCNA would fit in.
Besides, CCNA is more into basic Networking the way Cisco delivers it via their own devices. As a Software Engineer if you are trying to get a hang of core Networking, I'd say stick to Andrew Tannenbaum, or Douglas Comer, W. Richard Stevens, etc. kind of great folks.

CCNA (Cisco Certified Network Associate) is a category of technical certifications offered by Cisco for early-career networking professionals. The CCNA is the second level of accreditation, one step above Cisco Certified Entry Networking Technician (CCENT) and directly below the CCNP (Cisco Certified Network Professional). Cisco offers five Cisco Career Certification programs and levels of accreditation: Entry, Associate, Professional, Expert and Architect.
There is always a shortage of good network engineers.
having certifications line CCNA or CCNP will enhance your chance to get a job in the field of IT Infrastructure.
Having only a certification will not help, you should also have good knowledge.
CCNA is the first step in Cisco Certifications & it doesn't have any prerequisites.
A person from both technical & non-technical background can take up the exam.
With this certification, you get a knowledge on both Cisco specific networking & generic networking.
Since these certifications are widely recognized across the world, this will definitely add a weight to your resume.
Doing these courses or certification for the sake of certificate is worthless. Do it for knowledge purpose. Certificates will expire but not knowledge.
Aim for next level certifications like CCNP & CCIE, in a present scenario having only CCNA is not advised.
Cisco has introduced many other verticals in their certification, example:
Security, Voice, Wireless, Data center, etc.
Routing & Switching certification there from the beginning & its evergreen. Once you finish routing & switching, you may choose the vertical that interests you more, though it is not compulsory to have CCNA routing & switching certification to pursue other certifications, it is advised to undergo the training on routing & switching.
