Question 4. In CRC there is no error if the remainder at the receiver is ----.

equal to the remainder at the sender

zero

non-zero

the quotient at the sender

Question 5. 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

Hub

Bridge

GateWay

Repeater

1965, Germany

1950, USA

1950, Japan

Question 8. 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

the number of bit errors per twenty four hours of continuous operation on an asynchronous line

The probability that one or more errors will be undetected when an error detection scheme is used

the probability that one or more errors will be detected when an error detection mechanism is used

signal to noise ratio divided by the ratio of energy per bit to noise per hertz
