You want to be in the networking field?
You can work towards the 70-410 exam, and get a entry microsoft cert for window servers.
Unless you want to go the linux enterprise route, than by all means red hat.
Both are in demand for servers.
If you are going red hat route, helps to have the Linux+/LPIC cert aswell.
Net+ is another good cert from CompTIA, but you already proved you have what it takes with the CCNA to understand a network.
Not every job uses Cisco though..depends on your employer for your Cert pathway.
I think having the CCNA should be enough to get a decent entry position from some business, than from there learn what they use, and work towards a cert with them. Move up the ladder as you work.
~Hope I could help.
