192.9.200.1:FTP
FTP-192.9.200.1
192.9.200.1:80
192.9.200.1:21
Answer: 192.9.200.1:21

Definitely the only one that makes sense, as FTP (layer 7 protocol) relies on TCP at layer 4 on port 21.

A user has attempted to retrieve a Web document, but their browser displays an "Unrecognized Format" Message. What is the most likely problem?
Internet connection is slow.
Cannot read the file format.
Your server is returning the wrong document.
The client does not have access privileges.
answer: Cannot read the file format.

--> Agreed. They probably do not have the correct plugin, or their browser does not support the file format they are trying to access.

Which of the following file formats is not used to store still image data?
JPG
GIF
GIF89a
AVI
answer: AVI

--> Yup, AVI is for movie files, definitely not "still image"

Which of the following file formats are used for full-motion audio and video? (Choose all that apply.)
MPEG-1
MPEG-2
JPG
AVI
Answer: MPEG-1 and 2, AVI

--> Agreed. JPG is obviously a still image file format.

You are given an IP address of 125.63.17.2 and a subnet mask of 255.255.0.0. Which part of the IP address is the network portion and which is the host portion?
125 is the network portion and 63.17.2 is the host portion.
125.63 is the network portion and 17.2 is the host portion.
125 is the host portion and 63.17.2 is the network portion.
125.63 is the host portion and 17.2 is the network portion.
answer:125.63 is the network portion and 17.2 is the host portion

--> The way to answer that question is to look at the subnet mask: 255.255.0.0
In binary, this subnet mask would be 11111111.11111111.00000000.00000000
All the bits with a value of one are Network bits, all the bits w/ a value of 0 are Host bits. Here the first 16 bits are network bits -- you may also see the /16 notation to reflect this. In other words, the first 2 octets are your network ID. The IP address is 125.63.17.2; the first two octets are 125.63

A __________ connects multiple networks and can make intelligent decisions on the route to transmit data.
Hub
Switch
Router
Gateway
answer: router

--> Yup, a router it is. Keyword: intelligent. Therefore, hub (layer 1) is out of the picture

Your network performance has decreased to the point that your users are complaining. After monitoring the network, you discover that the Engineering section has been transferring large drafting files among themselves via the network. You have decided to localize the network traffic generated on the Engineering portion of the network. What network connectivity device would you use?
Bridge
Switch
Hub
Router
Answer: Router (router to segment the network)keyword here is " localize"

--> I disagree. I would think they want a bridge to segment the network. We are not talking about creating TWO subnets here, but to segment ONE existing network. At least that's how I read the question... The bridge will filter packets at the MAC address level (layer 2) and will keep the Engineering traffic inside of that segment.

Which of the following utilities will display your current TCP/IP session including addresses of hosts connected to your computer and port numbers?
PING
NETSTAT
ARP
IPCONFIG
answer: NETSTAT

--> Bingo!


What protocol is least secure?
PPP
L2TP
JAVA
SMTP
????? I kno JAVA is not a protocol

--> This is a silly question. Java is obviously NOT a protocol, therefore it is out of the equation. L2TP uses IPSec and is extremely secure. PPP uses no security, but neither does SMTP. PPP is a CONNECTION protocol, therefore I would think that this is the one they want...

On DNS Servers, the MX record
allows multiple domain names to be assigned to the same IP address.
contains information of what email server processes email for the domain.
is used to assign an alias for the Host.
is the first entry in every DNS server
Answer:contains information of what email server processes email for the domain.

--> Yup, it is a Mail Server -- also referred to as Mail eXchange, thus M record -- record for DNS.

Domain Name System is a network service that provides ______________.
Name resolution between international domains.
Name resolution between commercial enterprises and the U.S. government.
Name resolution between an IP address and a NetBIOS name.
Name resolution between a fully qualified domain name and an IP address.

answer:Name resolution between a fully qualified domain name and an IP address.

--> Agreed. Also used to resolve hostname to IP address.

On DNS Servers, the A record
Contains a mapping of IP address to the Host's name.
is the first entry in every DNS server.
contains information of what email server processes email for the domain.
allows multiple domain names to be assigned to the same IP address.

Answer:Contains a mapping of IP address to the Host's name

-->Yup. The first entry is always an SOA record, or Start Of Authority record. And no, the second record is NEVER an SOB record

On DNS Servers, the CNAME record
Contains a mapping of IP address to the Host's name.
is the first entry in every DNS server.
contains information of what email server processes email for the domain.
allows multiple domain names to be assigned to the same IP address

Answer:contains information of what email server processes email for the domain.

-->Nope. A CNAME is a Canonical Name record, an alias. For example, there is no machine on the Microsoft Network for which the hostname is www -- yet, millions of surfers point their browsers to www.microsoft.com every day and get what they are looking for. That is because in DNS, a CNAME record translate this alias of www to the right hostname.

Which of the following are an authentication protocol?
Kerberos
ACL
ICMP
SNMP

Answer:Kerberos

--> Right again! Kerberos V.5 is the authentication used by Microsoft in Win 2000. Long live NTLM that used to be the same thing for NT 4...


Hope this helped.

Freak I dont mean to challenge you, but:

You are given an IP address of 125.63.17.2 and a subnet mask of
255.255.0.0. Which part of the IP address is the network portion and
which is the host portion?
125 is the network portion and 63.17.2 is the host portion.
125.63 is the network portion and 17.2 is the host portion.
125 is the host portion and 63.17.2 is the network portion.
125.63 is the host portion and 17.2 is the network portion.
answer:125.63 is the network portion and 17.2 is the host portion

class A= 1-126
class B= 128-191
class C= 192-223

So since that first octet starts with 125 does that not fall into the class A address, making its subnet mask 255.0.0.0 making the network address 125 and the rest of the IP address the host. Please correct me if I am wrong.

Thanks freak you are the man.

for the question on MGEG-1 and MPEG-2 supporting audio and movies I referred to Sybex study guide by GROTH, page 379 under the section about "MOTION PICTURE EXPERTS GROUP-MPEG.

STILL NOT SURE IF I AM RIGHT, BUT THAT IS WHAT THE BOOK SAYS.

WHO IS RIGHT THE FREAK OR GROTH.

Hey Cuts, Thanks for your post. I have not looked into the MPEG thing yet, but I will
As for the IP thing, sorry but you are wrong. It does not matter whether the class of my subnet mask and IP address match or not, ie you can have a class A IP and a class C subnet mask w/ no problem. The only difference is that if you subnet w/ a class A Subnet mask, you have 24 host bits, therefore 16,777,214 available IP addresses to give to your hosts. If you subnet w/ a class C subnet mask, you only have 254 valid IP addresses to give your hosts. Once again, you can freely mix and match your IP and Subnet classes, as long as you still get the amount of IPs you need...

Freak I guess I was a little confused as to what the whole purpose of a subnet mask was.

I thought the reason you have a default subnet mask is so that the subnet mask can acompany the IP address (when packets are being sent across the network. Anyways the subnet mask is suppose to let routers I guess know which portion of the ip address is the network portion and which is the host portion, so that if it looks at a packets destination Ip address and look at the attached subnet mask the router (i guess) can determine whether the packets needs to be sent outside the netwokr or sent to host within the network.

If the IP address 125.2.3.4 and the subnet mask is 255.255.255.0 then the router will think the network part of the packets IP address is 125.2.3 and the host portion is 4.

if the packet is meant to stay within the network it would be sent outside the network by the router because the router will compare the network ID of the packet and the network ID of where the packet is coming from and determine that networks dont match, thus sending the packet to another network. When in fact the packet should have been kept within the network.

I think the correct subnet should be 255.255.255.0


MAYBE I AM CONFUSED, I THOUGHT I HAD THIS SUBNETTING THING DOWN, AT lEAST THE BASIC STUFF.
