Oops, time's up! Suicidal, put down your crayon, & pay attention.
Section 1 - Subnetting
1-1)
Machine 1 IP address: 10.0.0.5/29
Machine 2 IP address: 10.0.0.12/29
No. The /29 indicates a subnet mask of 255.255.255.248, or a subnet size of 8 hosts. The first subnet is IP range 10.0.0.0 - 10.0.0.7, the second subnet is IP range 10.0.0.8 - 10.0.0.15. Thus they are on different subnets.
1-2)
Machine 1 IP address: 172.168.245.36/26
Machine 2 IP address: 172.168.245.184/26
This time the subnet is 255.255.255.192, or a subnet size of 64 hosts. The first subnet is 172.168.245.0 - 172.168.245.63, the second is 172.168.245.64 - 172.168.245.127, the third is 172.168.245.128 - 172.168.245.191, & the fourth & final subnet is 172.168.245.192 - 172.168.245.255. Machine 1 is on the first subnet, while machine 2 falls into the third subnet. Again, they are on different subnets.
1-3) A customer for an unknown ISP has been assigned a block of static IPs ranging from 63.226.80.31 - 63.226.80.63. What is his subnet mask?
This one's easy. He has a block of 32 IP addresses, requiring a 5-bit host ID. Thus the subnet mask is /27, or 255.255.255.224.
Section 2 - IP addressing
2-1) Is 172.168.36.85 a valid global IP address? Why or why not?
No. the entire 172.168.x.x range is reserved for private IPs, and are not routable on the 'net.
2-2) What class of IP is 225.71.85.32?
225.x.x.x falls into class D.
2-3) What class of IP is 63.226.80.31?
63.x.x.x falls into class A.
Section 3 - Cabling
3-1) Describe the pinout of a crossover cable.
1 - 3
2 - 6
3 - 1
4 - 4
5 - 5
6 - 2
7 - 7
8 - 8
3-2) Describe the pinout of a rollover cable.
1 - 8
2 - 7
3 - 6
4 - 5
5 - 4
6 - 3
7 - 2
8 - 1
3-3) What is the maximum length for ethernet cabling without a repeater?
100 meters.
Section 4 - The Cisco 675
4-1) What DSL encapsulation model does the Cisco 675 use?
The Cisco 675 uses CAP mode.
4-2) What is the default server pool address for a Cisco 675?
The Cisco hands out IP's in the 10.0.0.x range, starting with 10.0.0.2. Thus the server pool address is 10.0.0.2.
4-3) How many NAT entries does the Cisco 675 support?
The Cisco 675 has a 50 entry NAT table.
4-4) If you needed the Cisco 675 to operate on an eth0 address of 192.168.1.1, & hand out IP's starting with 192.168.1.5 & ending with 192.168.1.15, what five commands would you need to use?
cbos#set interface eth0 address 192.168.1.1
cbos#set interface eth0 netmask 255.255.255.0
cbos#set dhcp server pool 0 address 192.168.1.5
cbos#set dhcp server pool 0 size 11
cbos#set dhcp server pool 0 gateway 255.255.255.0
4-5) Does the Cisco 675 support virtual IP addresses? If so, could you set a virtual IP of 192.168.36.1?
Yes, the Cisco 675 supports virtual IPs. No, you could not set 192.168.36.1 as a virtual IP address. Virtual IPs must be "real," and routable on the internet. 192.168.x.x is a private IP address, & cannot be a virtual IP in the Cisco.
4-6) What sector of the Cisco 675's NVRAM is the running configuration stored in?
Sector 6 stores the running configuration.
Section 5 - Suicidal is an Asshole
5-1) What is your name?
Suicidal
5-2) Do you agree to answer the next two questions truthfully?
Uhh... I don't understand...
5-3) If my next question is "Are you an asshole?", would your answer to it be the same as your answer to this question?
Uhh... I don't understand...
5-4) Are you an asshole?
I think so...
End of test.
