Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
|
|
If the central switch or server fails, the whole network is down
|
|
|
Requires a high performance switch or server in the centre as all traffic passes through it.
|
|
|
Very expensive due to the amount of cabling required.
|
|
|
It can handle very high data traffic rates
|
Detailed explanation-1: -The arrangement wherein every network node is connected to every other node of the network, many connections serve no major purpose. This leads to redundancy of many network connections. A lot of cabling is required. Thus, the costs incurred in setup and maintenance are high.
Detailed explanation-2: -However, mesh topologies also have their disadvantages: full mesh networks can be impractical to set up because of the high number of connections needed. many connections require a lot of maintenance.
Detailed explanation-3: -Mesh topology provides an inherent advantage that there is no single point of failure. Overall performance of the setup is independent of a single node or a single system. Sites that are geographically close can communicate with each other. Its main drawback is maintenance and key maintenance.
Detailed explanation-4: -Tree Topology A hierarchical layout that links together groups of nodes. Creates parent-child dependencies between root nodes and regular nodes. This layout can be vulnerable to failure if a root node has a problem. This topology is complicated and difficult to manage and it uses a lot of cable.
