QUESTION 1

How many bits are needed to identify 20 different subnets? 3, 4, 5, or 6?

QUESTION 2 Which of the following addresses does not correctly identify a subnet mask?

255.255.255.64

255.255.192.0

255.255.255.0

255.224.0.0

QUESTION 3 Suppose you have a class C network and you have a upto 4 different subnets in the network. What is the appropriate subnet mask for this network? Assume fixed subnet mask and not variable length subnet mask (VLSM). 255.255.255.0

255.255.255.192

255.255.255.64

255.255.0.0

QUESTION 4 Suppose a network is configured using a subnet mask 255.255.255.240. How many distinct IP addresses are available to address devices in each subnet? 10, 20, 14, or 16?

QUESTION 5 Which of the following does not correctly identify on of the subnets in a network whose network address is 209.98.208.0 and a subnet mask of 255.255.255.240? 209.98.208.16

209.98.208.64

209.98.208.48

209.98.208.132

QUESTION 6 Which of the IP address is contained within a subnet whose address is 209.98.208.48? Given a network address of 209.98.208.0 and a mask of 255.255.255.240. This question follows from the previous question in this quiz.

209.98.208.54

209.98.208.68

209.98.208.128

209.98.208.63

QUESTION 7 To which subnet does the device 209.98.208.74 belong to. Given a network address of 209.98.208.0 and a subnet mask of 255.255.255.240.

209.98.209.128

209.98.208.64

209.98.208.32

209.98.208.80

QUESTION 8 Which of the following is false about routing in IP networks?

Routers use a routing table to route packets. End to end paths are pre-determined before a packet is sent out of a source. Routing algorithms are used to make routing decisions in a router. Routing protocols are used to exchange route information among the neighboring routers.

QUESTION 9 Which of the following is false about Autonomous systems present in the Internet?

Autonomous system consists of a set of routers managed by a single orgnaization.

Routers within an autonomous system use Interior gateway protocol to exchange reachability information among the routers within the autonomous system

Routers in an autonomous system may use exterior gateway protocol such as Border Gateway Protocol (BGP) to exchange routing information among routers in neighboring aautonomous systems.

A packet can be routed by a router in an Autonomous system only if it knows the exact physical path to the destination network of the packet.

QUESTION 10 Which of the following statement is false?

An ARP table may consist of a mapping between the IP address and the MAC address of a device.

IP networks may be fragmented to meet maximum transmission unit requirements of the underlying network.

A router can only connect two underlying networks of the same kind and that run on the same lower layer protocols.

When an IP packet moves form one kind of network to another kind of network, new lower layer (data link and physical) headers may be appended.

Explanation / Answer

Total subnet = 2n

n = number of bits required

Number of bits should be greater than 4 because 4 bit results 24 = 16

Bits required is 5
