CCNA really got use? i heard some ppl said those cert not really useful.
I'm speaking from 5 years of experience with only a diploma, without a certification. So take it with a pinch of salt.
In practice, yes, it is not really useful, real life scenario is just really case to case basis. A test can never fully cover 100%. (They never ever teach you how to tidy up a super messy cables isn't it? And the test given is always assumed that no ERRORS in routers or devices. U have to find out what those errors are)
Yet without a cert, chances are, you wouldn't even score an interview in a job. Cert is just there for a chance to score an interview. Unless u can really prove u know your stuff during interview, chances are low (they are not going to give u a switch/server in the interview room to show your magic! haha!)
So for me, I really pray really really hard to God for help to get an interview and the rest is just prove your stuff during interview.
I hands on from desktop/servers/switches/firewall routers/ port forwarding/ dns/ AD/ exchange/ MDaemon Mail SVR/ A, MX records/ Domain administration/ write NT backup scripts/ etc. I even tided a server room with more than 80-100+ cables that looks like spaghetti on a bowl.
Some examples: the 7 layers of OSI i learn in poly? in 5 years 0 use. Not even in Holdings company I work for has use for it.
the cmds we learn in CISCO routers? None. Just copy and paste scripts and press enter. Most firewalls/routers are almost GUI ready now (yet slower compared to cmd lines)
But seriously, jack of all trades are always in demand (cover2-3 jobs) but remember that jack of all trades are MASTERS of NONE.
