NETWORKING ESSENTIALS EXAM QUESTIONS

NETWORKING ESSENTIALS EXAM QUESTIONS (70-058)



My contribution consists of 105 questions. I didn’t include the scenarios because there is a lot of discussion going on about some of the answers. Just read the other braindumps and make up your own mind.

Good luck to you all and keep sending those braindumps!

There seems to be 5 categories off the scenario questions:

1. The 3 cities connected with T1 lines and as sort off backup the 16 28.8k modem lines.
  The main question is whether of not sixteen 28.8k modems will provide 1 Mbps, as a backup for the T1 line.
2. The email network and NetBios names
3. How to reduce network utilization.
  120 users evenly spread across 3 servers, TCP/IP, Network traffic increase from 30% to 70% in a 10BaseT network.
4. The mixed network of Windows 95, Windows NT and Macintosh.
  Just remember Mac’s don’t work with NwLink (IPX/SPX)
5. Rebuild LAN to improve security.
  Pay close attention if the question mentions "disk stripping with" or "disk stripping without parity".

2 Ethernet's, one NetBEUI, the other NwLink. Need connectivity device to allow communication and reduce traffic

Repeater
Bridge
Router
Gateway

Answer: D

Note:	Correct me if I’m wrong, but only a gateway is able to handle two different transport protocols!
	A bridge or router can combine an Ethernet segment with a Tokenring segment as long as they use the same transport protocol.

One segment Ethernet, the other Token ring all running IPX you want to filter IPX addressing to filter data.
1. repeater
2. bridge
3. router
4. gateway
```
Answer: C
```
Note: Watch for the word "filter". When you want to filter you use a router instead of a bridge!
Gateway would be too sophisticated because a router or bridge is able to connect Ethernet and Tokenring. A gateway would only be necessary when there would also be two different transport protocols. But that is not the case because there both running IPX.
You have a network that uses both NetBEUI and TCP/IP you want to segment your network into 3 parts equally distributing the workstations and you want to use both protocols. What device should you use to perform this task?
1. Router
2. Brouter
3. Bridge
4. Gateway
Answer: D
Connect a NetBEUI network segment to Unix/NFS.
1. repeater
2. router
3. bridge
4. gateway
```
Answer: D
```
Note: This one makes sense, but a cheap repeater with some software like PC-NFS or other can do that at a fraction of the cost. Not
