Being a B.Sc graduate, you would have studied LINUX during your graduation. The syllabus of Linux at Mumbai University forms a strong base for RHCSA (Provided you have studied it logically).
There is a huge scope. Linux being open source is used a lot, mostly by organizations and government too. Also, most of the servers are Linux based. There are very few people who opt for RHCSA. Most of the IT graduates look for web development, app development or software testing kind of roles. A few go for hardware and networking or CCNA. And very few for RHCSA. This will also open up a window for you to explore cyber security and ethical hacking. Go for it. All the best.
