That's good advice, but it's not really practical. The average company isn't going to hire a new dude in any sort of networking position without at least 2 years exp under his belt. Not even for a junior role.
The easiest route for dude is to just try to get a help desk job in some capacity, and that means getting some Microsoft certs. As a level 1 tech/help desk you're 99% more likely to be asked to do some basic Windows/Office troubleshooting than you would be asked to troubleshoot routers/switches/firewalls/etc.
He can go for his CCNA, network+, security+, etc. But no one is gonna hire dude for any networking or security job considering he has 0 experience. I always give new cats trying to get in the game the same advice. Get your A+ because it's always a requirement. Learn about the Windows OS, Office apps (mainly Word, Excel, & Outlook), and basic networking (what's an IP address, what's a default gateway, what's DHCP/DNS).
That's the path I used to get my 1st help desk gig. I had my A+, MCP, CCNA by the time I had my 1st one, but for my actual job, the CCNA was pretty worthless since them nikkas wouldn't even let be breathe on a router/switch, and with good reason.
But hey why listen to me, I'm just another lost nikka
