Subject: Net Essentials brain dump
Took the NET ESSENTIALS exam on June 26th, PASSED with a 948.
EXHIBIT questions:
mesh network displayed (know what a mesh looks like)
3 offices: T1 ----- TI -------T1, one link goes down.
Can everyone still communicate, and at 1 Mbps?
2 offices: L.A. T1 à Chicago, Chicago T1 à NY
Can everyone still communicate, and at 1 Mbps?
Bus network, Terminated on both ends (50 ohms), Grounded on one end.
Cable = 0 ohms end to end
à replace cable
PARAGRAPH questions:
[3] questions - similar scenarios wanting - data protection (raid
levels ), hardware protection (UPS), backing up, virus protection,
tracking logons (auditing), security, ect
[3] questions, all very similar, Network performance down, need to
cut efficiency 50%
(they gave answers like - replacing cable, NICs, hubs ..)
to all of these questions I answered [d] - does not fullfill requirement
[2] questions - similar - lists stuff about internal LAN and other
company's LANs, although question really only pertains to local LAN.
Asks about setting up NETBIOS names for server and all clients, and asks
when eventually connected to the other LANs, with this scheme still be
active?? something like that
Proposed items included giving HEX #s for computer names, the other
question said numbers & characters up to 15. And then some security
questions. They're easy questions, but they just through all this
mumbo-jumbo stuff in to confuse you.
DEFINITION questions:
gateway
router
brouter
crosstalk
other easy stuff . (cable type & components)
UNC à computer name \ share name
connection oriented = assured delivery
MISCELLANEOUS:

[3] Situations like "Nancy cannot connect to net. Everyone else up &
running. NIC initialized fine"
à know wrong frame type, wrong transciever type,
Unix & DOS clients connected to NT server. 1 more server added, why
can UNIX client communicate?
3 - network tool questions (I think all my answers were Protocol

Good luck everyone!
I couldn't have passed without those Transender practice exams, and
this Braindump site.
There were many things I would of never picked up from just the Net
Essentials Self-paced book.
