I,II,III and IV.

Question 2. On a class B network, how many hosts are available at each site with a subnet mask of 248?





Question 3. Because the configuration infor-mation for a DHCP client is received dynamically, you must use which utility to read the current configuration to verify the settings?





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

Question 5. Error detection at a data link level is achieved by

bit stuffing

cyclic redundancy codes

Hamming codes


Question 6. You have a class A network address 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?

Question 7. Which of the following provides a storage mechanism for incoming mail but does not allow a user to download messages selectively?





Question 8. In CRC there is no error if the remainder at the receiver is ----.

equal to the remainder at the sender



the quotient at the sender

Question 9. The Fiber Distributed Data Interface (FDDI) standard calls for nodes to be:

attached to a data bus in the form of a transmissive star coupler.

attached to a pair of fiber rings carrying signals in opposite directions.

attached to a network of star couplers that detect collisions and transmit only one signal to the next level.

attached to fibers by passive T couplers.

Question 10. 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
