Hi,
I gathered in this document a complete list of all questions submitted on this web site. I grouped related questions, as they may be the same worded differently. I have not passed the test just yet, so I do not know if the questions are accurate, or if
I marked my answers with "<", while most the other one who contributed to this web site used the answer in bold. I am not sure how this document will get translated, so if you do not see any "bold" answers, well, you’ll have to guess. Here is the 71
Enjoy.
1a) - Install CAT5 TP in new 100BT Ethernet. Which tool would you use to test the FULL bandwidth capabilities of the cables?
1b) – What tool would you use to monitor network performance and facilitate troubleshooting of network problems? I.e.: isolate a failing network adapter.
2.- 16 modems to connect a Wan site at 1 MB
a) Not possible?
There is not much data on this question, but assuming a system with 16 modems at today’s throughput (56kbs), that would make a modem pool of 896Kbit or about 89KBytes, far from the 1 Mega Bytes asked. That is the only answer proposed here and the only
3)2 Ethernets, one NetBEUI, the other NwLink. Need connectivity device to allow communication and reduce traffic
3a) One segment Ethernet, the other Token ring all running IPX you want to filter IPX addressing to filter data.
Although just about everyone suggested gateway, the MS Press NetEss self-paced Course book (page 563) seems to say the router would be the best choice. I would answer the router.
3b) Two Ethernet segments, using TCXP/IP and NetBEUI, what to use
Although the repeater can do that as well, if performance is an issue, the brouter would be a better choice. The exam question may be worded differently, so the repeater may be a solution as well.
3c) You want to segment your network in 3 segments (300 users) All using TCP/IP (and NetBEUI?)
3d) Same as 3c), but using NetBEUI
4) 78 locations, 50 to 100 computers per site. WfW and Win95 clients, among others. No mention of NT. What administrative plan to initiate.
Since there are no mention of NT, the answer cannot be a). Obviously only c) make sense here. Read the question during the exam for other probable clues.
5- 5MB file token ring @ 4Mb/sec to Ethernet takes 2 minutes. Ethernet to token ring takes 30 seconds.
That question left me perplex. My answer would be a) Everyone else picked b) But that does not explain why it takes 4 times longer for input vs output. The same amount of data has to pass on the same wires, encountering the same Bottlenecks. Sorry, I d
6- 3 terminators on a coaxial bus, showed a graphic
7- Which type of server do processing on the server for client program. (Chose all)
8- What would you include to manage your network
9- 3 cities linked with 3 T1 lines and 28Kb modems.
Required: Any PC can access ant other PC or servers across 3 sites.
Optional: 1 Mb at all time and connectivity if one link fails
Proposed: 2 T1 lines
9a) See 9- for required & optionals
Proposed: 3 x T1 lines in triangle
Question 9 has been seen worded differently by various contributors to this site. I strongly suggest you read the question in the exam with great detail.
10- Greg can't see the network but his network card fires OK.
11- You install a network card and your system no longer boots
12- What OS allows you to share and use resources on them.
(Chose all)
12a- Select all that *only* uses a password on a shared resource:
13- What WAN link will give you 100 Mb or over throughput
ATM can give you 633 Mbps, but commercialy we see 155Mbps. T1 is typically 1.5Mbps
13a) What WAN link can you use at ANY speed
According to the NetEss self paced book (p 596) Frame relay would be a better fit. Usually ATM is fixed at "only" 155Mbps. ATM seems to be the answer of choice in the other links. Again, that is according on the wording of the question above. The e
14- What WAN link will give you a reliable switched connection
15- Which link is not switcheable
16- You need to give a cheap 19.2K baud connection 24 hours/day
17- What would you use to make a 100mb network, budget is low
That answer does not make sense, I assume it should be 100BaseT Question and answer was taken litterally from an other link.
18- Your company has taken a short lease (6 months) of a small building. Your task is to design the network. Part of the lease says not to change any part of the building and money is short. Which network topology would you chose
Make sense, but UTP would be cheaper.
19) You need to connect to network which uses totally different protocol, What would you use
a) Gateway <
19a) User want to access an IBM 3090 via terminal emulation. What device should he use?
20- You measure a thinnet cable via the T, What reading do you get
21- What reading would you get from an Arcnet terminator
22- Your friend has used TV cable for his network. What is wrong
23- Select all where *Can* you use the same NETBIOS name:
24- Anne's computer can access the network, but everybody else can...?
a) Network connection at Anne's computer <
25- What is designed to replace analog phones (PSTN)
26- Major WAN network with e-mail will be connected to your Company. Note: NetBIOS name must be less or equal to 15 chars.
Required: link 30,000 devices with NetBIOS
Optional: Meaningful naming scheme
Proposed: Use unique 15 char hex numbers
Actually, a NetBIOS name has 16 characters, but the 16th is reserved for suffix.
27- See 26- for required and optional
Proposed: 8 chars for location,
4 for functions
2 for something else.
a) Meet required and optional <
28- 120 users evenly spread across 3 servers, TCP/IP
Required: Reduce network utilization 50%
Optional: Minimize cost, expandability and not affect admin
Proposed: Replace Hubs, Nics and wiring to 100MB
28a) Same as 28 but:
Proposed: change all Ethernet hubs for switches
a) Meet required and all optionals <
28b)- see 28 for required and optionals
Proposed: Reduce packet size from 1514 to 768
Increase TCP/IP windows from 4K to 16K
and something else non-sense.
a) Do not meet the required nor the optionals. <
29- Where do Bridge, Router, repeater and gateway sits on the OSI model?
Answers: Bridge: Data Link <
Router: Network <
Repeater: Physical <
Gateway: Transport, Session, presentation, application <?
On the gateway, the NetEss self paced course says that some gateways are implemented on ALL layers, but is typically seen on the application layer only. See page: 574…Who’s right?
29a) What works at transport level and above layer of OSI
30- Mixed network of Win95/NT and Macintosh.
Brouters between LANs, Mixed protocols.
Required: Reduce traffic (broadcasts) without altering functionality
Proposed: Remove all protocols but IPX
Turn off bridging part of Brouters.
Make sense but not much data to argue.
31- What network topology (Exhibits looks like a star of David)
a) Mesh <
32- Mixed Dos, Unix, NT. New NT server is added, but Only the Unix systems cannot see it.
33- Intermittent network problem on Thinnet. Mix of RG58 /U solid core and RG58 A/U stranded cable. After checking cables you have infinite Ohm reading. The T connector also shows infinite and the terminator shows 50 ohm, What must you repair?
34- You get 0 Ohm on coax center to edge, 50 Ohms on T piece and 50 Ohm on Terminator. What is the problem?
35- Install NIC on IRQ 3, what could it conflict with?
36- Question on thinnet (No question given)
a) It uses BNC T connectors <
37- Question on UTP
a) Use Cat 3,4 or 5 cable. <
38- New computer not working, but the network software seems to have initialized properly. (No IRQ conflict)
38a) Same as 38 but using NWare.
Both 38 and 38a are the most probable, but it could also be other answers. I would read the exam question carefully.
39- 5 users WfW, which protocol is recommended?
a) IPX (NetBIOS was not offered as solution) <
40- Which protocol are routable? Chose all
41- SLIP and PPP, which one supports Dynamic IP and compression? Has to do with a 5 years old modem used to connect to Internet but Cannot assign IP address automatically (should be SLIP)
41a) What provides error correction and compression (flow control?)
41b) You have 5 networks over leased telephone lines to form a Wan. 5 networks using various transport protocols (such as IP, IPX, NetBEUI). Compression is used for datalink Communications. Which Datalink communication protocol is being used on
42- Network performance accessing a server is decreasing. NT server stats are CPU 8%, 2 pagefaults/sec, disk utilization is 25%.
20 pagefaults per sec is considered a lot, 2 is not. When tuning, usually there are 3 bottlenecks, CPU, Memory or I/Os. Since CPU and memory are not an issue (only 2 pagefaults/sec), the only other choice would be I/O, thus a RAID solution.
43- What NDIS and ODI designed to overcome?
44- 2 PCs communicates over LAN. Using some network diagnosis tools, you see that both have the same hardware and NIC settings (Including MAC address in exhibit).
45- What do you need in a UNC name? (Chose all)
Seems like everybody else answered b) & d). I would chose a) and d) as Microsoft usually shows the definition of a UNC as: \\servername\sharename\[pathname]
46- Rebuild LAN to improve security.
Required: High level of Security and fast recoverability I n less than 2 hours. Assure data protection and fault tolerance
Optionals: Virus protection on shares, logged tracking of net access (auditing) Protection against password guessing programs.
Proposed: Daily backups. Use UPS, Implement policy on shares, Install virus software and disk striping with parity(?) on all servers. Note: Other contributors says disk striping without parity? Make users change their password every 40 days.
46a) Same as 46-, but add auditing on proposed and RAID 1 instead of raid 0 (5?).
Questions 46 and 46a are seen tru a lot of links on this web site, but there are a lot of confusion on the content of the question. What is required, optional etc…
47- Network performance reports large number of Broadcasts storm, Using NetBEUI. What should you do?
48- Network of 10 Windows NT workstations, what to do with security (chose all) Note: wording not so straight forward)
49- Network of 10 windows 95 stations. What to do with security
50- There may be a question on 5-4-3 rules. That is a rule saying the 10Base2 can have a maximum of 5 segments, 4 repeaters and 3 segments with nodes. (2 segments are only cables)
51- 5 Win95 stations in peer-peer. What protocol is best?
Given that NetBEUI is not in the answer, that does not leave much other choice.
52- Using 10BaseT what is needed to get 300 meters
a) repeaters <
53- Win95 & NT servers. What would you implement to minimize the administration required to protect network data?
Security on all shares. <
54- Which protocol is used in packet switching to find the shortest route and most cost effective, measure hops?
55- What can you use as a backbone for 10Base5
56- Which cable media would you use for 100 Mbps Ethernet? Chose all(?)
d) is the best answer, but c) is also a possible solution using 100BaseFX fiber.
57- 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?
It is logical, but I am unsure of this answer.
58- One storey building, bunch of computers to hook up and no pre-installed cable in the building. You have 1 meter of ceiling space. Which would you install? (No mention of cost)
I am not sure of this one. a) would be a good choice, but c) is easier to install and d) would be the best choice for Token ring. The real answer is probably easier to find out once we can read the real question of the exam.
59- What is a characteristic of 802.3 10BaseT standard
60- What is a characteristic of the 802.3 100BT fast Ethernet?
61- What is a characteristic of IEEE 802.3 10base2 standard
62- What High level of network protocol provides file-sharing on networks that uses NetBIOS
That is the only ones that makes sense to me. IPX uses NBIPX, TCP/IP uses NetBT and NetBEUI uses NBF to do NetBIOS name resolution.
63- Name value that specifies how IP addresses are interpreted:
63a) What dictates the value of a TCP/IP address
I am not sure I fully understand the questions, but I assume it means that the IP address is divised in HostID and SubnetID. If it is the case, then e) in 63- and a) in 63a) would be the answer.
64- Which of the following can provide WAN with Digital voice, Data and video?
65- What connectivity device to connect 10BT to 10Base5?
No answer was provided in previous links, but any bridge, router or repeater can do that. Repeater would be the cheapest solution.
66- Christina’s computer WAS working and now cannot connect to the server All other computer can, why?
Not enough date to judge, but makes sense.
67- What provide assurance of packet delivery?
68- Connect a NetBEUI network segment to Unix/NFS.
This one makes sense, but a cheapo repeater with some software like PC-NFS or other can do that at a fraction of the cost. Not much data to give a better answer.
69- How do you view NetBIOS names on a subnet?
Usually the DOS command nbstat –c would do that, but given the answers above, a) is the best answer.
70- Intermittent network errors, cable spawn 2 buildings, The exhibit shows ground at both ends of the cable.
71- 802.x is /collision detect
.4 is token bus and .5 is token ring. Not too sure what is .12(?)
Good luck,
Vince.
