1.2 Explain the characteristics of network topologies and network types

Question 1

In this topology, every site has a connection to every other site, a drawback is that one new site requires a new WAN link between the new site and every other existing site.

Answer 1

Full mesh topology

Question 2

This topology is highly fault tolerant, has a high level of redundancy, but wiring is complicated, costs are high and troubleshooting is difficult

Answer 2

Full mesh topology

Question 3

This is a communication pathway that has additional links to connects all nodes in case one link goes down.

Answer 3

Redundancy

Question 4

In this topology selected sites are inter connected via direct links whereas sites that have less frequent communication can communicate via another site.

It uses fewer links than a full mesh topology and more links than a hub and spoke topology for interconnecting the same number of sites

Answer 4

Partial mesh topology

Question 5

This topology provides optimal routes between selected sites, avoids the expense of interconnecting every site to every other site, but it is less fault tolerant than full mesh.

Answer 5

Partial mesh topology

Question 6

The ability to adapt to a network failure and function if a node is moved from one location to another

Answer 6

Self Healing

Question 7

This topology doesn’t need cables, each network node is inter connected to other nodes on the network, it extends the transmission distance by relay the signal from one computer to another. It is also inexpensive to implement, highly scalable, reliable and self configuring.

Answer 7

Wireless Mesh Topology

Question 8

This topology is self healing

Answer 8

Wireless mesh

Question 9

This topology has a hub at the center with a collection of clients individually connected to the hub. Today it is used with an ethernet switch at the center and unshielded twisted pair cables (UTP) connecting the switch to the clients.

Answer 9

Star topology

Question 10

This topology is the easiest to expand

Answer 10

star topology

Question 11

In this topology the hub or the switch is a single point of failure.

Answer 11

Star topology

Question 12

In this type of connection, each connected device requires a single cable to be connected to a hub or switch

Answer 12

Point to point

Question 13

This topology is typically used with ethernet technologies.

Answer 13

Star topology
