Subject: Here's my 70-058 Networking essentials braindump

 

Just got back from "writing" net essentials. (18 May 1998).Passed with 879- not bad – 4th attempt.(Blush). 1 down 5 to go.Excuses- moving, changing jobs, partying too much, no net exp and girls - also doing a degree in computers at the same time. Degrees are much easier! On the 1st attempt I had no practice exams and got 66%. I heard of MCP prep- bought those – waste of money! 2nd attempt got 74%.

Heard of transcenders - got those and then heard of this site. I printed EVERY entry and tried to summerize them. It was just too much info and I was in a rush. 3rd attempt got 76% missed by 3%. I really enjoyed seeing Bill Gates get a pie in the face in Brussels! In rage I read the entire Wave NT4 track with 988 ave on Transcenders (Worth every cent!). Summerized the entire net ess braindump site and then passed the @#$$% exam. U can't pass without this site – thanks Richard. Learn from my mistakes & never give up! Excuse the spelling.

 

In exam 1& 4 were basically the same.

Exam2. I had 2 scenarios and the rest short questions.

Exam 3. I had 2 scenarios again. It was 99% the same as Ex2. Maybe because I 'wrote' it 2 weeks later in the same month.

Exam4. I had the following: (About 8 scenarios near the end.)

 

Netbios naming questions.

Cable length queses.(basic).

The 2 & 3 T1 lines (in all ex)

No wireless in any of the exams.

No Wins / Hosts / LMHOSTS/ DHCP / DNS (Them being the answers)

The 2 hrs downtime scenario (1 with auditing the other without.)

ATM & P.A were coorect where they showed up. (Be carefull! There are exceptions to this rule: Frame Relay supplies band width as needed Not ATM and Windows Performance Moniter can also be used to identify trends over time and establish a baseline for trouble shooting, but if they don't list this then P.A does the same trick.)

Set the default MAC address to factory settings ques. (in all ex)

Mesh.

ISDN Basic to replace tel. (POTS)lines. (in all ex)

The Barbara question.(5 yr old comp doesn't support compression which protocol being used? SLIP)

Which protocols are routable (TCP/IP, IPX/SPX,Appletalk) DLC, Netbeui, NOT. (in all ex)

CPU 8%,Page faults 2 per sec Ans Disk stripping with parity.

Connection orientated = assured delivery (in all ex)

Connectionless = unreliable delivery. (in all ex)

(They asked 2 questions twice with just different wording - same answers)

NT4 & Workstaion = user level sec & 95 = share level. (in all ex)

Which connectivity device works at the transport layer and above?

Answer: Gateway.

Ethernet net. Software iniatializes.Can't see the server. what's wrong ans wrong transeiver (in all ex)

Nwlink net .Software iniatializes.Can't see the server.What's wrong.ans Wrong frame type(in all ex)

Which are dial up protocols ans SLIP , PPP

The famous change Ethernet packet size from 1516-576bytes. Increase TCP/IP window from 4096-16384

Ans d: doesn't meet required. (in all ex)

Repeater to join 10 Base T seg 300m long (in total)

What measures hops between routers to determine best paths ans: RIP not other 13 listed (in all ex)

 

Answer the questions on the site called QUESTIONS. They're a great help.

 

Below is a summary the tougher questions which will help u tremendously….

How do you increase lagging Disk Access time? Implement disk striping w/parity

What is the name of the "number sequence" you need for handling an IP-Address ?

Answer: Subnetmask

With which devices can you measure the bandwidth of a new installation side?

Network Analyzer

Remember that WINS resolves NetBIOS names to IP addresses. DHCP automatically assigns IP addresses to clients.

High disktimes and pagefaults are often due to memory problems, High CPU times a new CPU is required.

What is the name of the "number sequence" you need for handling an IP-Address ?

Answer: Subnetmask

Know transmission speeds of various mediums. Specifically, 10-Base whatever, 100-base TX, Fiber, ATM, modems.

Know that DLC resides in the Data link layer and is associated with

Mainframes and Hewlett Packard printers

Application server does the processing for the clients request

Know that Wins server resolves Netbios

DHCP resolves/configures TCP/IP

0 ohms -----short in cable

Infinite----break in cable

50 Ohms in terminators

 

Session - Netbios, notice that Session starts with an 'S' and ends with 'N', other way round for Netbios

Termination of Thinnet BUS network:

A. Must only be terminated with two terminators. Any more or any less is wrong.
B. Terminators must be 50 ohm.
C. Only one end of the bus should be grounded. If both ends are grounded, you're going to have problems.

 

You have two network servers, both running Win NT server. You must ensure that data is extremely secure and that you have a fail safe disaster recovery plan in place. Network downtime should be kept to an absolute minimum if there is a disaster. Which method of data redundancy should you choose? 

A.RAID Level 0 and a tape backup rotation with tapes stored on site.
B.RAID Level 1 and a tape backup rotation with tapes stored off site.
C.RAID Level 5 and a tape backup rotation with tapes stored off site.
D.Tape Backup rotation with tapes stored off site.

 

You have a workstation that cannot connect to the network. All other workstations can access all network resources. What is your first step in troubleshooting?  

A.Run diagnostics on the workstation's NIC.
B.Run diagnostics on the server's NIC.
C.Make sure the network is properly terminated.
D.Re-install the workstation's network client software.

 

You have a workstation that can NO LONGER access the network. Which is most likely the problem?  

A.The frame type on the workstation's NIC is incorrectly configured.
B.The network cabling to the workstation's NIC is loose or disconnected.
C.The workstation is running the wrong network communication protocol.
D.The workstation's RAM is defective.

 

When running WINS to resolve NetBIOS computer names, which is it important? Check all that apply:

A.To make sure that no two computers on the network has the same name.
B.To make sure that no computer has the same name as a domain on the network.
C.To make sure that no computer has the same name as a workgroup on the network.
D.To make sure that no computer has the same name as a server on the network.

 

What tool can be used to measure the bandwidth of a network medium?

A.Time Domain Reflectometer
B.Protocol Analyzer
C.Advanced Cable Tester
D.Oscilloscope

You have a WAN with 25 servers and 1000 workstations (500 Windows NT, 300 Macs, 100 Unix and 75 DOS). The network currently runs NetBEUI, TCP/IP and Apple Talk. You are having a problem with broadcast storms. Your brouters are set to broadcast messages across all segments.

Required:

Optional:

Workstations should still be able to communicate using computer names as well as IP addresses

Proposed Solution:

You have offices in Atlanta, Chicago and Los Angeles. All of your offices must be able to communicate with all other offices at 1Mbps and communications should continue between all offices at 1Mbps even if one link should fail.

Proposed: Two T1 links and one 9600 baud asynchronous line.

Answer: Doesn't meet required results. All offices can't communicate with all other offices at 1Mbps if one of the T1 links goes out.

Same question as above, but the proposed solution is a 16 port RAS server at each location running 8 28.8Kbps connections synchronously.

Same answer. 8 x 28.8 doesn't make a 1Mbps connection.

A computer uses NWLink IPX and not able to access the network. Hardware is not the problem. What is the probable cause?  

A.Incorrect sub-net mask on the client
B.Incorrect IP address on the client
C.Incorrect Frame Type on the client
D.Incorrect WIN.INI file on the client 

 

Answer is C.

A client in an Ethernet network is not able to access the network.
Initialisation was successful. All other clients can access the network.
Hardware is not a problem.

What is the problem?

A. Insufficient extended memory in the client
B. Network adapter in server configured to the wrong transceiver
C. Network adapter in client configured to the wrong transceiver
D. There are an excess number of collisions on the media.  

Answer is C

In the past year, 55 clients have been added to a 10BaseT network. The network is slow in peak times. What is the most economical solution?  

A.Replace Ethernet adapters with FDDI?
B.Replace Ethernet concentrators with Ethernet Switches
C.Replace Ethernet components with 100Mbps ATM
D.Replace Ethernet components with 16Mbps token ring. 

A network with 27 servers and 750 clients running NetBEUI, IPX, TCP/IP.
A client running NWLink IPX is installed which is not able to access some shared network resources. All others are able to access.
Cause?

A.Subnet mask setting on client incorrect
B.Protocol mismatch between new client and inaccessible shared resources
C.NetBIOS names duplicated
D.Cable failure between client and inaccessible resource.  

I chose B.

The only scenario I hadn't seen word for word in the braindumps:

Required:

Centralised control of access to shared resources

Optional:

1.Track access and attempted access to shared resources

2.Track attempts to guess passwords

3.Implement a method to protect user accounts from password breaking.  

Solution:

Implement NTFS with user level security on all servers. Set appropriate access control on shared resources. Change passwords every 40 days. Disk striping with parity. Backups.  

My answer:

I said meets required and one optional.
I had this question in addition to the other two scenarios that had one with auditing and one without!

Had another one on SLIP and PPP, something to the effect of which protocols are used for remote access. Answer just listed two choices, both SLIP and PPP so I checked them both. Seemed too easy but I only missed 5 so I guess I got that one right

 

Had the computer naming problem (actually two questions), i.e use hexadecimal scheme for unique names etc. Read the question carefully. The question I had seemed to be different from what I had seen before. It stated that the users had to be named by what they did or something like that. In the second proposed solution (not the hex one), the naming scheme had two separate parts in the proposed solution. One for the servers and one for the clients.

 

Had one where the cable tested 0 ohms and the terminators were 50 ohms and the T-connectors were something – can't remember the details ( said replace the cable – 0 ohms means there's a short, infinite ohms means the cable is open (broken))

- Which protocol do you use for Dial-up communication? (Choose all that apply)

SLIP, PPP, were the only choices so I choose both 

 

LAN is over 300 meters on 10 BaseT cable what do you use? (repeater, baseband)

3 cities are linked with 2 T1 lines.

Required - Communicate over 1mbps

Optional – 1 - Fault tolerance 2 - Keep connection if 1 line goes down

My answer: Yes to required, no to optional

3 cities link with 3 T1 lines

Required - Communicate over 1mbps

Optional – 1 - Fault tolerance 2 - Keep connection if 1 line goes down

My answer: Yes all required and optional

- Which protocols are routable?

 

- A question about infinite on cable, 50ohm on terminators, and 0 on T-connectors, what's the problem?

- Definition question. How is communication between routers done using? (RIP)

- Performance monitor shows 3 things %Processor Time, %Page Faults/s (2), and %Disk Reads (25). What should you do? I'm not sure about the numbers but I picked add RAM

Brouters will allow the broadcast to pass through if the bridging is enables, if disabled will only allow routing protocol to pass through and no broadcast. (remember Netbui in non-routable)

- You have two segments using TCP/IP and want to lower cross domain traffic. What do you install?

Ans: Install a router

- Which limitation are NDIS and ODI designed to overcome?

Ans: The need for proprietary network interface drivers for each network operating system and protocol.  

- What does the MAC driver do?

Ans: It Provides low-level access to network adapters by providing data transmittion support and some basic adapter management functions.

- What does the transport protocol do?

Ans: It defines how data should be presented to the next receiving layer, packages the data accordingly, and then passes data to the application though the seesion layer interface

- Connect win95 and MSDOS comupters to see data. What protocol to use?

Ans:Netbeui

- How do you view NETBIOS names on a network?

Ans. Win sever

- What would you include to manage your network?

Ans. SNMP

- You find that the network is getting slower and when using the performance monitor you see that: CPU time 4% page/sec 2% disk 44%. What to do.

Ans. Disk striping with parity.

- What wan link can you use at ANY speed.

Ans. Frame relay  

- What WAN link will give you a reliable switched connection.

Ans. X.25

Setting:
Major wan network with e-mail will be connected to your company. Required result: to create Netbios names for the server and clients that would be work and stay unique when you connect to the Wan.

Optional results: To be able to distinguish the server name, computer name and department name through the Netbios name.

Solution: Use a unique hexadecimal number for each computer.

Answer: satisfies required only

Major wan network with e-mail will be connected to your company.

Required result: To create Netbios names for the server and clients that would work and stay unique when you connect to the wan.

Optional results: to be able to distinguish the server name, computer name and department name through the Netbios name.

Solution: use a number that designates a certain number of digits for the department, another few for the user's name, another few for the computer name, and link the Netbios name with the e-mail address.

My answer: Meet required and all optional

- ethernet network is not functioning.
You use DVM to check: cable, between the core and the shield: 0 ohm, T connector: infinite, terminators both 50 ohms. What do you do:

Ans. Replace the cable.

- network performance in accessing the server is decreasing. Performance monitor results show %processor Time = 8%, page faults= 2/seconds and Disk Utilization= 25%. How should you increase performance?

Ans. Install RAID Disk striping of some sort (to speed up disk access)

- Scenario: You have a mixed network of win95 and Mac workstations. You use brouters between the Lans and you use multiple protocols (IPX, TCP/IP, APPLETALK, NETBEUI).

Main: you must reduce network traffic (brocasts) without altering functionality.

Solution: remove every protocol except IPX and disable bridging on the brouters.

Ans. Does not meet required.

 

Network performance reports a large number of broadcast storms. The network uses NETBEUI. What is the best thing to do?

Ans. Use router and TCP/IP instead of Netbeui.

- your network is using multiple protocols (APPLETALK, NETBEUI, TCP/IP, NWLINK) for MACS, NETWARE, UNIX, Pcs. There is excessive network traffic and poor performance. How can you reduce network traffic and improve performance?

Choose only one protocol for the network. There should be minimal degradation of machine functionality as a result of the protocol change.

Ans. Doesn't meet required. Mac won't work with IPX

- In a small network w/ 8-10 Windows 95' Computers use: Netbeui (or IPX - NOT NWLINK <--NT)

- Raid Level 0: Disk Striping (No Fault Tolerance)

Raid Level 1: Disk Mirroring, Duplexing (Fault Tolerant)

Raid Level 5: Disk Striping with Parity (Fault Tolerant), Data and

Parity on seperate disks.

Protocol analyzers are also known as network analyzers.

Ethernet switchesare the same as intelligent hubs.
