Subject: 70-58 - Network Essentials
I passed Network Essentials Today with 913 - Thanks to everyone who contributed
I found 6 questions were of the Here's the solution does it meet the requirement and the optional requirements type.
Of these Three were bandwidth utilisation - you are up to 70% and you need to reduce it by 50%. One of these suggested fiddling with TCP windows and packet sizes. One was changing protocols and making Brouters into routers. One was making the whole network FDDI
Two were WAN - Offices in three cities- need a 1mb link and need it to be tolerant of a single line failure. Optionally give 1MB even if one line fails.
One had 2 T1 links and 2 9600 links
One was the 8* 28.8 modems in a triangle
There were 2 questions on OSI layers
I found the All People Send Their Network Data
Physically - a great help
About 6/7 questions on Bridging, Routing & gateways
Such as ...
Ethernet & Token ring - what would you use to connect them Broadcast storms - what would you need
TCP/IP separate LANs - what would you use to connect them (and limit traffic)
Ethernet LAN to IBM Mainframe - what would you use etc
I also had the slow copying from Token ring to Ethernet question ( thanks to Scott for the answer - bigger frame sizes on Token Ring)
There were several Fred can no longer see the network / Mary has a new LAN card and can't see the network type questions.
A couple of IRQ/MAC address questions
SCSI controller and LAN card - Machine fails to boot - remove LAN card now boots - what is the problem.
LAN card on IRQ3 - Server uses COM1 ,COM2 & LPT1 what does it clash with
Two identical LAN cards don't work - what needs changing (they specifically give the MAC address)
There were a couple of WAN questions
What would you need if you wanted 100mb - X25/ISDN/T1/ATM
What would you need to use any available bandwidth - X25/ISDN/Frame Relay/ATM
I had a couple of Cable type questions - eg what does 10baseT need/what does 100baseT need
That's about all I can think of - Thanks again for anyone who helped
