What is the size (in bytes) of an Internet Protocol (IP) header?
20
You have been hired to design a company's network. The company has an assigned Class C network address of 192.168.30.0 255.255.255.0. Your client wants the network to be configured with 8 subnets with 14 hosts each. Will this configuration work, and if so, how many subnets and hosts can be on the network?
Yes, this will work. The network will have 14 hosts per subnet and more than 8 subnets for future growth. Four bits will be used for hosts for a total of 14. The last 4 bits will be used to get a total of 14 subnets.
You have been hired to design a company's Internet Protocol (IP) addressing scheme. The company has an assigned Class C network address of 192.168.30.0 255.255.255.0. Your client wants 4 subnets with 28 hosts per subnet. How many bits are required for subnets? How many bits are required for hosts? What will the new mask be for this network?
3 subnet bits, 5 host bits, and mask 255.255.255.224
The default mask for a Class B network is 255.255.0.0. How many subnet bits do you need in order to define 600 subnets with 55 hosts per subnet, and what is the new subnet mask for the network?
10 subnet bits with a mask of 255.255.255.192
You have a Class B network with a mask of 255.255.248.0 and an address of 172.16.0.0. How many subnets and hosts per subnet can you get?
30 subnets and 2046 hosts
Which of the following protocols is a connectionless network layer protocol in the AppleTalk suite?
DDP
Convert the binary mask 11111111.11111111.11110000.00000000 into decimal. What is the decimal representation of this mask?
255.255.240.0
If you have a Class B network with an Internet Protocol (IP) address of 172.16.168.2 and a mask of 255.255.240.0, what is the subnetwork address?
172.16.160.0
If you have a Class C network with an Internet Protocol (IP) subnet address of 192.168.1.32 and a mask of 255.255.255.224, what is the valid range for host addresses?
192.168.1.33 through 192.168.1.62
Which of the following is a valid AppleTalk network layer address?
1.10
AppleTalk network layer node (or host) addresses can be 8 bits long. How many valid host addresses can you have on one AppleTalk network?
Question 14 answers
254
AppleTalk networks originally used a data-link layer known as LocalTalk. What is the transfer rate of LocalTalk?
230 Kbps
Host A wants to communicate with Host B, but before Host A can send information, it must determine whether Host B is on the same subnetwork. Host A's Internet Protocol (IP) address is 192.168.176.171 and the mask is 255.255.255.224. Host B's IP address is 192.168.176.195 and the mask is 255.255.255.224. Are they on the same subnetwork?
No, they are not on the same subnetwork. Host A's subnetwork address is 192.168.176.160 and Host B's subnetwork address is 192.168.176.192.
If you have a Class B network with an address of 172.16.0.0, which subnet mask will provide up to 2000 subnets with at least 28 hosts per subnet?
255.255.255.224
Which of the following Internet Protocol (IP) address classes identifies multicast addresses?
Class D
What is the valid decimal range for the first byte of a Class B address?
128 through 191
What is the significance of the following Internet Protocol (IP) address: 127.0.0.1?
It is used for internal diagnostic purposes on IP hosts.
What are the two main functions of the flag bits in the Internet Protocol (IP) header?
They specify whether this is the last fragment or if there are more fragments to follow.
What is the purpose of the Time To Live (TTL) field in the Internet Protocol (IP) header?
It specifies the number of intermediate hops a datagram has passed through on the way to the destination.
Correct It is decremented by each router as it is forwarded.
What are the private address ranges for Class A, Class B, and Class C networks?
10.0.0.0 through 10.255.255.255
172.16.0.0 through 172.31.255.255
192.168.0.0 through 192.168.255.255
Which of the following are valid Internetwork Packet Exchange (IPX) network layer addresses?
100.AAD112FF0992.1105
BAD.00C010FCAAD1.0451
Which of the following are Internetwork Packet Exchange (IPX) routing protocols?
RIP
NLSP
