content: I am learning the basic rules of DNS servers right now, VLANs from what I understand are built into the switch for remote access right?  I am scheduled to take the following certs: Network +, Security +, CEH, and hopefully the CISSP. Are there anymore you would advise?  My wife works in mental health, and I vent to her about what I can about my job, but most of it is classified so I can only speak in generalities.  I get mixed messages regarding which certifications are actually valued vs which ones are useful. Any guidance there?
