Network Topology Set 2 — Test 1

Correct Answer: C. C. Bus, ring and star topology
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.

Correct Answer: A. A. Brouters
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.

Correct Answer: B. B. Hybrid
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.

Correct Answer: C. C. Bus based, ring based
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.

Correct Answer: D. D. Ethernet protocol
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.

Correct Answer: A. A. Ring
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.

Correct Answer: D. D. Ethernet
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.

Correct Answer: B. B. False
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.

Correct Answer: D. D. Hybrid topology
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.
