This set of Computer Network Multiple Choice Questions & Answers (MCQs) focuses on “Network Topology – Set 2”.
1. The three topologies associated with LANs are _________
a) Mesh, Tree and Bus topology
b) Tree, Circular and Ring topology
c) Bus, Ring and Star topology
d) Hybrid, Mesh and Star topology
View Answer
Explanation: Bus, Ring and Star topology are related to LANs whereas Mesh, Tree, Circular and Hybrid are simply network topologies. The best topology for LAN is Star topology.
2. A pseudo topology that combines a Star topology with either Ring or Bus topology is known as ___________
a) Router
b) Hub
c) Ethernet
d) Switches
View Answer
Explanation: Hubs are used to connect segments of LAN. It is a common connection point for devices present in a network. Star topology is usually combined with Bus topology using Hub as the backbone of Bus topology. Router, Ethernet and Switches are network components and can be introduced in network topologies.
3. The Tree topology is employed in network using ________
a) Brouters
b) LAN
c) Switches
d) WAN
View Answer
Explanation: Brouters are bridged routers that do the routing function at OSI layer 2. Tree topology uses Brouters to get involved in a network. LAN is a private network used by one organization whereas WAN is used in a large geographical area. WAN is composed of multiple LANs. Switches are network components.
4. ________ topology is a combination of two or more topologies.
a) Star
b) Hybrid
c) Bus
d) Ring
View Answer
Explanation: A Hybrid topology comprises of a mixture of Star, Mesh, Ring and Bus topology. Hybrid topology finds its application in Wide Area Networks. Connecting two similar network topologies cannot be termed as Hybrid topology. It is a highly reliable network.
5. The two types of LAN deployed are __________ and ___________
a) Mesh based, Bus based
b) Hybrid based, Star based
c) Bus based, Ring based
d) Ring based, Tree based
View Answer
Explanation: Bus and Ring topology are the two types of network deployed in LAN due to their many advantages over other network topologies. The Bus topology is easy to install, it uses established standards and it requires fewer media than other topologies. The Ring topology on the other hand is very easy to troubleshoot as each device incorporates as a Repeater.
6. Bus Architecture is implemented in LANs using ________
a) Address Resolution Protocol (ARP)
b) Hypertext Transfer Protocol (HTTP)
c) File Transfer Protocol (FTP)
d) Ethernet Protocol
View Answer
Explanation: Ethernet is the most widely installed local area network (LAN) technology. Ethernet is a link layer protocol in the TCP/IP stack. It describes how network devices can format data to other devices on the same network segment. The protocols ARP, HTTP and FTP are network protocols and have different applications.
7. Token Ring and FDDI configurations use the _________ topology.
a) ring
b) star
c) mesh
d) bus
View Answer
Explanation: FDDI is used for combining the Token Ring, Fast Ethernet and Fiber Optic Cable. Thus FDDI acts as a network backbone for connecting LANs to create MANs and WANs. FDDI uses dual-ring topology for this purpose instead of other network topologies.
8. Which protocol is most frequently used in Star topology?
a) Modem
b) Cable
c) DSL
d) Ethernet
View Answer
Explanation: In a star network a number of devices and actuators are connected to a central hub. An advantage of Star topology is that data can be transferred using a simple serial communication protocol. Thus Ethernet is the protocol that makes this advantage possible.
9. Linear network topology is more expensive than other topologies.
a) True
b) False
View Answer
Explanation: Linear network topology such as Bus topology is not expensive than other topologies. It requires less cable than Star topology. It is also easy to install computers and other devices in Linear network topology.
10. The diagram given below represents ___________
a) Fully connected topology
b) Mesh topology
c) Star topology
d) Hybrid topology
View Answer
Explanation: A hybrid topology is a type of network topology that combines two or more different network topologies e.g. star, mesh, bus and star topology. Hybrid topology helps is increasing the signal strength.
