I have done BEng (Hons) Electronics and Communication degree. Presently I am working as a trainee at satellite broadcast company. My interest is more towards communication path that electronics. I am thinking to start following CISCO CCNA routing and switching program to gain more knowledge on networking. But I don't know weather this will be worth the time and money I spend on it. Do you think doing this program will would help my path? if you think this program will not benefit a telecommunication engineer then please suggest any other program.
