Hello my name is Mike and I passed today with a 862, not bad....Here is my study sheet that I acquired by reading the braindumps..
Application- Telnet, FTP, SMTP, Gateways,
Presentation- SMB, Redirecter
Session- NetBIOS
Transport- SPX, TCP, UDP (transport protocols use routing tables)
Network- IP, IPX, NWLink, NetBEUI, DDP (Apple), Routers
Data Link- DLC, (IBM, HP printing), Bridge
Physical-Repeaters, Where most problems occur
SNMP(Network Management) uses TCP/IP
Dial Up protocols
PPP-automatic IP, and compression
SLIP-found on older machines, doesn't do compression or IP addressing
Troubleshooting common answers:
Frame Relay offers bandwidth on demand.
Netware(IPX) = frametype
Token Ring = Ring speed or protocol mismatch
Ethernet = transceiver type
NDIS and ODI
allow network cards to be independent of the protocols.
ODI eliminates need for custom driver for every protocol/NIC combination
vendors create cards to ODI standard
What do NDIS and ODI give you? A: NICs independent from protocols
NetBIOS universal naming convention:
\\computername\sharename
High disktimes and pagefaults are often due to memory problems, High CPU times a new CPU is required.
RIP- Is for distance vectoring and for determining the number of hops.
Broadband-(AAU)Analog, Amplifiers, and Unidirectional
Baseband-(BDR)Bi-directional, Digital, Repeater
NDIS and ODI are designed to bind multiple protocols to a single NIC. NDIS allows network protocols to be independent of adapter card. Both Will bind multiple protocol stacks and NICs however ODI is Novell and NDIS is Microsoft.!
RAID levels
Level 0- Striping without parity
Level 1- Disk mirroring or duplexing
Level 5- Disk striping with parity
All are supported by NT and have built in Fault Tolerance!!!
IRQ Specs.
Com2 and Com4 use IRQ-3
Com1 and Com3 use IRQ- 4
LPT1 uses IRQ-7
LPT2 uses IRQ-5
Cable Spec.
10BaseT- uses UTP or STP cable and transmits upto 100 meters
10Base2- uses Thin Coax cable and transmits upto 185 meters
10Base5-Uses Thick Coax cable and can transmit upto 500 meters(Known as Standard Ethernet)
UTP cable
CAT 1-4mbps
CAT 3-10mbps
CAT 4-16mbps
CAT 5-100mbps
3 cities with 3 T1 links- meets required and all optional
3 cities with 2 T1 links- meets required only
2 cards set up identically can't access network?-change to factory settings
card with IRQ 3 setting ? conflicts with com 2
upgrade from 10baseT to 100baseT?- change to category 5 cable
On the two long questions about NetBIOS naming with 20,000 client and servers, required was unique names which must still work after WAN is established, optional must be able to tell server function and user and departments (or something like that) first
Tool to identify a faulty network card- Protocol Analyzer
Token Ring to Ethernet transfer speed differences is because of FRAME SIZE DIFFERENCES not TCP window or speed of Ethernet.
High level file protocol is SMP if FTP is not offered. AFP is at presentation so is lower.
Three major topologies:
BUS-cheap and easy to work with
Slow and cable break can affect whole network
RING-equal access
One machine can affect whole network
STAR-easy to expand, and set-up
Hub is required
QUESTIONS TO LOOK FOR!
Peer-to-Peer use NWLink
Windows for Workgroups use IPX or NetBUEI
PC not networking but software seems to have initilized? Wrong transciever/frame type
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
You can ping a serverby it's IP address (numerical), but can't reach it by it's name. What's wrong?
Answer: Wins-Server.
With which devices can you measure the bandwidth of a new installation side ?
Network Analyzer
NT can do both User-level and Share Level Security!
You have five windows 95 peer to peer network. What is the protocol used? DLC
TIPS:
When in doubt choose ATM for WAN related questions
Choose Protocol Analyzer for troubleshooting
Choose either frame type or transciever for related problems
Remember that WINS resolves NetBIOS names to IP addresses. DHCP automatically
assigns IP addresses to clients.
ATM - except for one that can increase it's bandwidth capability (which you put frame relay as the answer), answer is ATM
Token Ring to Ethernet transfer speed differences is because of FRAME SIZE DIFFERENCES not TCP window or speed of Ethernet.
Don't get mad if you fail remember this: 80% of all applicants fail the first time around. Two things to remember pray before you take the test and Smile :-) no matter what happens after the test!!!
Good Luck and thank you to everybody who had helped me prepare for this exam..
