Subject: Networking Essentials 070-058
Hello knowledge seekers. I took the Networking Essentials exam 070-058 today and passed with a score of 931 out of 1000 the first try. I used the Microsoft Networking Essentials book, some free exams from the net and cram notes from www.cramsession.com/. And of course the most useful of all The Braindumps. In fact the Braindumps is a must for people who want to pass the test with the first try. I read 80+ of the most recent braindumps before doing this test. But becareful about the answers on them. But as a rule of thumb the braindumps with scores of 900 and above are more believable. When in doubt research the answer.
I am on a budget and so can't afford the super expensive Transcenders. If you are like me then these NE sample test is just as good and in some cases better then the Transcenders. Here are the link to these FREE stuff.
With these link. I hope you can save hundreds of dollars.
And now finally onto our feature presentation. The dumps from my exam. In some cases where I do not remember the questions fully I used to sample test to reconstruct my lost memory.
1. There are 2 ethernet networks. You want to use both Netbeui and TCP/IP. Need a connectivity device that will allow communications and reduce traffic.
I chose b but no sure. Some dumps say gateway. Take your pick.
2. Which operating systems will allow you to share resource with a password?
a,b
3. You just installed a brand new 100mbps 100baseT ethernet network. What allows you to test its full bandwith?
d
4. You come back to work from holiday. Now your network has a severe broadcast storm. What device to use to isolate source of storm?
d
5. What device measure network traffic over time?
d
6. Which type of server provides processing power to run programs for client computers? (choose all that apply)
b
7. What is a characteristic of a client/server networks?
Client computers access a server that performas back-end services.
8. What provides reliable delivery of packets
a
9. Barbara's remote computer can be accessed via dial-up telephone lines. The computer is 5 years old and uses TCP/IP as transport protocol. The data link communications protocol used by computer cannot provide automatic IP addressing. What data link is it?
b
10 You want a data link communcations protocol that can provide secure data delivery and support compression. Which one?
b
11 Don't remember too well. But choosing from the list the ones that are use for data link communication in TCP/IP.
Of cource it must be SLIP and PPP.
12. This device lies in the network layer does broadcast filtering, and allow multiple connection points and the ability to find best route for transport.
a
13. What is characteristic of the IEEE 802.3 100baseX fast ethernet standard?
b
14.What is a characteristic of the IEEE 802.3 10baseT standard?
b
15. What is a benefit of both NDIS and ODI
They allow network adapters to be independent of of any particluar transport protocol
16. What is the function purpose of NDIS and ODI
Allow multiple protocols to bind to a single network adapter card.
17. You want to install a 100mbps backbone network that will connect 5 existing networks. Which media?
c
18 Your network uses Nwlink IPX. Initialization of your client computer's network software appears successful, but your client computers is not able to access the server. All of the other computers are able to access the server. What is the cause?
the network adapter in your client computer is configured to use thw wrong frame type.
19 Something very similar to 18 with Netware IPX/SPX. Same type of answer again. Wrong frame time with adapter card.
20 You are designing a peer-to-pper network that consists of 5 Microsoft Windows 95 computers. Which protocol?
No Netbeui so I selected NWlink IPX
21. You connect your Ethernet and token ring networks. Both networks use NWLink IPX. You want to use IPX addressing to filter data. Which device?
router
22. Segement 200 node network into 3 subnets. The network uses TCP/IP. Which device?
router.
23. Your network has 250 client computers. The network uses both TCP/IP and NetBEUI. You want to segement the network into 3 subnets. You want ot allow all of the computer to use both of the protocols to communicate with computers on all 3 subnets?
brouter.
24 Which network device is used to translate protocols?
gateway.
25. Your 10BaseT Ehternet network uses NetBEUI. Users of your client computers need access IBM 3090 mainframe computer by using a 3270 terminal. Which device?
gateway.
26. Which WAN connection provide transmission speed of faster than 100Mbps?
ATM
27. Your computer has a SCSI drive. You added a brand new network adapter card and the system will not boot. Whats wrong.
IRQ conflict between SCSI card and Network adapter card.
28 You install an Ethernet network adapter in a client computer. The computer's network software is initialized successfully, but the computer is not able to communicate with other computers on the network. All other client computers on the network are able to communicate. What is problem?
the transceiver setting on network adapter is incorrect.
29. Your network uses TCP/IP, NetBEUI and IPX/SPX. You add a new client to the network and it can share some but not all the resource.
Protocol mismatch between the the client computer and the unshareable resource.
30. You are trying to install a 100mbps second network in an office. There is a 1 m room in the ceiling. You want to minimize cost. What will you use?
I pick C UTP because it minimize cost and supports 100mbps (but is it category 5 UTP?)
31. What packet switching connection allows bandwidth to be used on demand?
b
32. You have 300 computers accessing a database server using a 56K Wan link. User complains of slow reaction time. You optimized the server. What will you do to increase speed.
I chose c because 300 people using a single 56k Wan link is ridculous inadequate.
33. You have a Win95 that needs to talk to a Windows 3.1 running netware Dos requestor. What do you need to install on Win95?
a
34. What High level of network protocol provides file-sharing on networks that uses NetBIOS
I selected H. but am not sure.
35. Two connected network. Ethernet and Token ring. File transfer from token ring to ethernet 5 min. From Ethernet to Toke ring 30 sec. Why?
Packet size for token ring bigger than ethernet.
36. Which provides the most reliable packet switched network?
a.
37 What can be used as a backbone for a 10base5 network?
Of cource it must be fiber optic. A
38. A question in which you insert a network adapter card which is set to use IRQ 3. What will it conflict with?
b
39. Neither new network adapter that you installed can access the network. Configuration of the cards are exactly identical. How do you make it work?
Change the MAC (hardware) address to factory settings.
My exhibit questions
40. Some exhibit with a network in which there is a bus ethernet network that resemble a T with the server extending out as one branch of the T being terminated by a resistor. The other ends of the T is terminated by resistors and of cource the main trunk has client computers. For a total of 3 resistor. Will not work. Why?
It is obvious that 3 resistor is a no no for a bus ethernet.
So rearrange to use only 2 resistor.
41. A bus ethernet network with 2 terminating resistor both grounded. Will not work. How to fix?
ground it probably since only 1 of the terminator should be grounded.
Scenario
42. 3 cities Chicago, Atlanta, LA. Want to design a LAN to connect.
Required: A WAN that will work
A WAN that be capable of transmitting at minimum of 1 Mbps.
Optional: Provide communication in case of single link failure
1 mbps in case of single link failure
Solution: Use 2 T1 and 2 56K.
satified required and one optional
43. Same as above but with 2 sets of 16 RAS modem (28.8 kps). Since even 16 * 28.8 is 460.8 kbps. It does not satisfy required. Alot of debate on this. Don't know if got this right.
44. Designing disaster recovery plan for network.
Required: Protect hardware from hardware failure. However, periods of downtime of less than 2 hours are acceptable. You must have reasonable controls to proctect data loss.
Optional: Track access to files
Prevent data from virus corruption
Solution.
Connect UPS to server
Set access-control security on all shared resource
Implement disk striping with parity
Daily backup, stapes stored off site.
audit
virus scan
Satisfy all required and all optional
45. same as above but no audit. So satisfy above and only 1 optional.
The Next Scenario Question differs in a tricky way from similar ones from Braindumps.
46. Situation: Company has rapid growth caused by increase in number of computer on network. Will add more computer next year. Broadcast storms are occurring with increasing frequency. Want to reduce storms. Has Nt Server, Mac, Win95. Using NetBEUI, TCP/IP, NWlink, AppleTalk. 4 brouter with bridging enabled.
Required:Reduce storm by 50 percent minmizing changes in function of client computers.
Optional: Minimize hardware costs
Minimize adminstrative cost
Allow for expansion
Proposed Solution: Turn off bridging on all brouter. Change Win 95 clients to using only TCP/IP. Change server and brouter to use only TCP/IP and AppleTalk.
I chose satisfy requirement and all optional. The tricky thing is that in past braindumps it says change protocol to IPX/SPX and turn brigding off. Because Mac can't use IPX/SPX it make it not satify required. It seems like the change is to throw people off. Remember to read questions carefully.
47. 10baseT network. Some situation in which network utilization has increased from 30% to 70%. Going to add more computers and some servers next year.
Required: Decrease utilization from 50 %
Optional: Allow for contiued growth
Maintain network utilization levels after planned edtions.
reduce cost.
Proposed solution. Change all cables to Fiber optic and change adapter to FDDI.
satisfy required and 2 of option since it does not reduce cost.
48. Same as above but decrease frame size from 1514 to 576. Replace Category 3 UTP able to Category 5. Increase TCP windows from 4096 bytes to 16384 byets.
Does no produce requried results.
Thats all I remember. The other 10 are they type of question you will find in Braindumps. So dig into the dumps and you should be OK. Good luck. Off to NT 4.0 Adminstration.
