Do the CCNA is interesting, and what website are you using?

Hi everyone,

I'm a Network Engineer with 5 years of experience. But I think my salary is low.

I want to pass some certifications like CCNA and CCNP from Cisco, but I don't know where to study.

I checked some websites like:

• study-ccna is free

• pingmynetwork is 99$

• networkacademy.io is free

I don't know if I should buy a platform or if the free ones are sufficient.

Thank you
