To all of you network security guru's

Can anyone provide the answers below?  I have a bet going with a colleague he
was wrong on half of them, however, I would like to double check with the
answers I have.  Tell me if my answers are wrong as they are next to the

b)	ALOHA 
c)	CSMA/CD
d)	TCP/IP
e)	Random 

3)	Why is OSPF called a link-state routing protocol? B

a)	It links networks together
b)	It monitors the state of network links or paths
c)	It links static routes together
d)	It translates between host and network links
e)	It defines Wide Area Network routes

4)	What type of attack is a SYN flood attack? A

a)	Denial of Service
b)	Software Destruction
c)	Hardware Destruction
d)	Information Gathering
e)	False data placement

5)	What is the first step in the address resolution process? 	A

a)	ARP looks for the name of the user in the cache
b)	ARP contacts a router for a route
c)	ARP checks for media type.
d)	ARP checks for the address on the Internet
e)	ARP checks if the address is on the local network
 

6)	If your client were concerned about intrusions where attacks looked as
though they were coming from a trusted source, what kind of attack would they be
expecting? B	
a)	IP counterfeiting.
b)	IP spoofing.
c)	IP capture.
d)	IP mirroring.
e)	IP matching

7)	Which defines encryption?  E

a)	It is a service that provides multiple copies of information to servers
participating in the Security Module.
b)	It is the process of replicating data to prevent unauthorized access
during transmission.
c)	It is a service that provides multiple copies of information to servers
participating in the Management Module.
d)	It is the process of encoding date for platform independent access.
e)	It is the process of encoding data to prevent unauthorized access during
transmission.

8)	Bob is attempting to connect to an ftp server named ftp.files.com which
resides on a separate subnet within Bob's organization.  Bob cannot ping the
server using its IP address.   He can successfully ping his default gateway and
the addresses of other computers on the same subnet as the ftp server.  What is
most likely the cause of the problem? E
a)	Bob's computer is set up with an incorrect default gateway
b)	Bob's computer has an incorrect subnet mask
c)	The IP configuration on the ftp server is incorrect
d)	The hosts file on Bob's computer has no entry for ftp.files.com
e)	There is no DNS configuration for ftp.files.com 

9)	The act of a packet, sent by a malicious or errant source, lying about
the host from which it came is called ________. E

a)	replacement.
b)	substitution.
c)	Piggy-backing.
d)	counterfeiting.
e)	spoofing.

b)	Configure each network adapter with a unique subnet mask
c)	Enable IP forwarding 
d)	Define TCP conventions
e)	Configure each network adapter with the same subnet mask



11)	Pete is unable to access a server on a remote subnet.  After monitoring
the network with a network analysis tool, Pete discovers that his computer is
broadcasting an ARP request for the MAC address associated with the IP of the
remote server.  No other users are having difficulty accessing the server.  What
is most likely the problem? 	
a)	Pete's computer has incorrect DNS configuration. C
b)	Pete's computer has an incorrect subnet mask.

I would advise you to do your take-home test for Comp. 101 yourself; you
could have done it easily in half the time it took to type it in.
