Explanation: Whenever a network is going to be divided by a router a number of factors needs to be considered when selecting a subnet mask. Two factors that need to be considered is the number of networks that you require and the maximum number of host each subnet will require.

Incorrect Answers:

B is incorrect; DHCP addressing is not relevant in the subnet mask design.

D is incorrect; since the number of hosts has to satisfy ALL of the subnets, we must accommodate the subnet with the highest number of hosts, so we need the maximums of each, and then take the largest of all the maximums.

E is incorrect; this task may need to be done but this task has nothing to do with designing the new subnet mask.

Q. 87

How many collisions are caused by transmitting and receiving frames simultaneously in a full-duplex Ethernet Technology?

A.One

B.Two

C.None

D.Several

Answer: C

Explanation: Full Duplex requires one and only one device to be hooked up to a switch port, and each switch port is a separate collision domain. Since there is no contention (the node has exclusive control of the segment) there are no collisions.

A, B and D are incorrect; it is impossible for collision to occur within a full duplex network.
