I dont see the numbers being high because salary depends on where you are located obviously if you are in USA you will make more money being CCNA. I see California paying highest to experienced worker $78,336 followed by Virginia $72,931.

If you are just starting out then ya its not going to be $70k+ it will be more likely be close to $50k.
