Welcome to Networking Quiz, Intermediate Level !!

Question 1. A 8-Mbps token ring has a token holding timer value of 10 msec. What is the longest frame (assume header bits are negligible) that can be sent on this ring?

8000 B frame

80,000 B frame

8 x 105 bit frame

10,000 B frame

Question 2. You have a class A network address 10.0.0.0 with 40 subnets, but are required to add 60 new subnets very soon. You would like to still allow for the largest possible number of host IDs per subnet. Which subnet mask should you assign?

255.240.0.0

255.248.0.0

255.252.0.0

255.254.0.0

Question 3. Error detection at a data link level is achieved by

bit stuffing

cyclic redundancy codes

Hamming codes

equalization

Question 4. You are working with a network that has the network ID 192.168.10.0. What subnet should you use that supports up to 25 hosts and a maximum number of subnets?

255.255.255.192

255.255.255.224

255.255.255.240

255.255.255.248

Question 5. On a class B network, how many hosts are available at each site with a subnet mask of 248?

16,382

8,190

4,094

2,046

Question 6. Which of the following technique is used for fragment?

a technique used in best-effort delivery systems to avoid endlessly looping packets

a technique used by protocols in which a lower level protocol accepts a message from a higher level protocol and places it in the data portion of the low level frame

one of the pieces that results when an IP gateway divides an IP datagram into smaller pieces for transmission across a network that cannot handle the original datagram size

all of the above

Question 7. Which of the following statement is incorrect?

if a host moves from one network to another, its IP address must change

routing uses the network portion of the IP address, the path taken by packets travelling to a host with multiple IP addresses depends on the address used.

IP addresses encode both a network and a host on that network, they do not specify an individual machine, but a connection to a network.

all of the above

Question 8. You are working with three networks that have the network IDs 192.168.5.0, 192.168.6.0, and 192.168.7.0. What subnet mask can you use to combine these addresses into one?

255.255.252.0

225.255.254.0

255.255.255.240

255.255.255.252

Question 9. Which of the following is the address of the router?

The IP address

The TCP address

The subnet mask

The default gateway

Question 10. The packets switching concept was first proposed

in the late 1980s for the Defense Ministry of US.

in the early 1960s for military communication systems, mainly to handle speech

in the late 1950s for Defense Ministry of US

none of the above
