118.0. "Networkings Essentials - questions" by KERNEL::ANDERSONS () Mon Mar 24 1997 10:41

Having just completed the MCSE, I would like to thank all the people that have put questions into this
notes conference. My last exam was the Networking Essentials and I managed to remember these
questions....Thanks for the help...

1)  What is the benefit of using NDIS/ODI compliant network adapters ?
        * Applications are written to the NDIS/ODI layer then any NDIS/ODI card will work.

2)  Which of these protocols allow Flow control and data compression
        * SLIP
        * PPP

3)  You have three buildings at your site, each building has it's own Ethernet network. You want to
connect all three networks together. Which media do you use ? (The longest distance between any two
buildings is 1000 meters.)
        * UTP
        * STP

        * Net Mask
        * MAC

5)  You are having problems with your network, examine the exhibit and diagnose the problem. (When you
look at the network diagram, you will see that you have a T shaped network with three BNC terminators.
        *  Re-design the network, and terminate the network correctly.

6)  Your users are complaining of intermittent network problems, examine the exhibit of the network
diagram and diagnose the problem.( in the exhibit you will see a network diagram that shows a coaxial
Ethernet network that spans two buildings, note that the cable is earthed at both ends)
        *  Earth the cable correctly

7)  Multi solution question about having a 1Mbps link between three sites. You have to keep a constant
1Mbps link, but the backup is a modem using RAS( not 1Mbps).

8)  When must a Netbios name be unique ?
        * The computer name must be unique on the local network.
        * In a DOMAIN
        * In a Workgroup
        * Must be unique when sharing a resource to the network.

9)  What is in the 10BaseT spec.
        * RJ45 connector
                                                                                
10)   What is in the 100BaseT spec.
        * Cat. 5 cable.

building, and money is short. Which network topology do you use ?
        * Star
        * Bus
        * Ethernet
        * X.25

18)  You have two networks joined by a gateway. One is Token Ring running at 4Mps and the other is
100BaseT running at 100Mbps. Users have been complaining about network performance. When you look into the
problem you notice that when coping a 5Mbyte file from the Token Ring network to the 100BaseT network it
takes 5mins. When you copy the file the other way around it only takes 30secs. What is th
e problem ( Didn't know the answer)
        * TCP/IP window size
        * Wrong frame size

19)  Which default IRQ setting is going to conflict with my network card, if the network cards IRQ is set
to 3(or 5...best thing to do is remember the default IRQ settings)

20)  You have a 486 computer with 16Mb of memory and a VGS graphics card. The hard disk is connected to a
SCSI card. When you install your new network card the system fails to boot. When you remove the network
card the system will boot. What is the problem ?
        * The SCSI card and the Network card are conflicting

21)  You have three computers in a client/server network. The two clients can not communicate with the 	
server or with each other. What is the likely problem ? (they show you some output from a network cards
diagnostic program, and then go on to say that both cards are identical. The output shows you the MAC
address)

118.3Some additional focusBIS7::CORTEBEECKVMS747 = OpenVMS for P7Fri Apr 25 1997 14:35117
    HI there,
    
    I've also passed the Netw. Essentials.
    
    Unforntunately I lack the excellence of memory of .0.
    However, I can give some genereal input on what to focus on when
    studying the Netw. Essential book.
    
    1. Know the IRQs numbers and usage by hearth. Thats good for 4 to 5
    questions
    
    2. Know at which layer a repeater, bridge, brouter, gateway work and
    what type of cabling and  protocols that they can accept and mix.
    
    3. kown the difference and attributes between SLIP and PPP and CSLIP.
    
    4. The book and questions are US focused. E.G. no questions on X25 but
    expect some on T1
    
    5. In the lesson of Advanced networks the  Sonet, SMDS, Frame Relay,
    etc... is discussed in the latest chapter of the book. However, a
    fairly high number of network planning questions are related to these
    few pages. FYI, the questions will not related to Sonet directely but
    to STS.
    
    6. Know which net protocol is installed by default on an NT server.
       Also, the questions are picky on what is routable and what not.
    
    7. As my mother tongue is Dutch, some questions were even more
    ambiguous then intended. I solved a lot of questions by excluding the
    wrong answers.
    
    8. The LAN cabling questions are  focused on 10BaseT questions.
    
    9. Another thing that is done regurlary is that (from appendix A)
    the questions will use the less known standard name. E.G. ISO is referred
    to as IEEE 802.1
    
    10. The network planning questions come in sets of 2. E.G. The same
    geographical reference is used to ask 2 different questions or they
    will mention the same question but propose 2 different solutions. I
    found this confusing.
    
    	The situation : You have 3 LANS, One in LA, Chicago and one in
    	Atlanta.
    
        Required Result (RR) :
    		All nodes must be able to connect to other nodes
    		You need to have a 1 Mb connection to each site
    
        Desired result (DR) :
    		You need a fail over possibility
    		the redudance must run at 1 Mbps.
    
     
    	Then you can see an exhibit with the citities connected by a T1 and
        a 9600 as a backup
    
    	Then you can pick between
    		all of the required results and all desired result are met
    		all of the required results but only 1 of the DRs is met
    		non of the RR is met but all of DRs are met
    		non of the RRs and DRs are met.  
    
    
    
    ===========================================================================
    	Same Chicago, Atlanta, Atlanta situation but the exhibit some a
    connection over RAS by 48 modem lines of 56 Kb. And you can pick out  the
    same answer.  (is worthwhile to do a little bit of arithmetics here as
    the 48 lines are distributed over the 6 links [2 from each city])
    
    
    12. You better know what a voltmeter, TDR, network analyzer, NT
    performance monitor, SMS and a SNMP mgt station are used for
    
    11. the specific from the memory.
    	1. An exhibit of a 10 Base T2 in a T configuration. You get a lot
    		of info on the cable length etc..
    		The possible solutions mention, network to long, etcc but
    		you should redesign the network
    	2. Shares can be protected by passwords.
    		mark the OSes that support this protection method
    			- WfW
    			- W95
    			- WNT WKS
    			- WNT Srv
        3. Which default protocol is installed on a NTAS?
    	4. Again a situation where you must decrease the network
    utilization with 50%. and the network must be able to accomdate
    additional nodes (RRs) It may not cost much and the solution must
    assure the same low netw utilization (drs)
    
    		the choosen solution : upgrade all the stuff from 10 base T
    to FDDI everywhere
    		Now start picking between All RRs+DRs are met/ RRS and only
    1 DR/ All RRs and no Drs/ None of the Results is achieved. 
    
    	The same situation and the same DRs and RRs. However the solution
    includes DECREASING the packet size, increasing the IP windows size
    and increasing aother thing that made sense.   
    
    	5. a network with heaps of server and different protocols including
    apple talk. The netw only uses bridges.
    There are too many broadcast storms. You must cut down the storms with at
    least 50 %. + it must be a cheap solution. RRs. The solution must also
    allow future extension of the network + keep the broadcast storms doen.
    		The choosen solution is to stop briding on the brouters
    and install TCP/IP on some of the PCs. Again are the Results met?
                                                          
        6. 2 Pcs get a new network card. The PCs boot without errors but
    they cannot reach the network. You
    started MSD. Then you'll get a list of DMA port, base memory and IRQ
    settings. Both the PCs have the same ETHERNET address.
    
    	7. So far for my 897 brain dump,  Dominiek
