4. Suggest the placement of Switch/Hub with justification.
5. Where will a repeater be placed in the suggested network layout? Justify your answer.

Answer 1

1. Star topology
   
2. WAN (Wide Area Network): Due to the large distance between Hyderabad and the USA, a WAN is required, as it can cover connections across different countries and continents.
3. The production division is the most suitable location for the server because it has the highest number of computers.
4. A device should be installed in each block since every block contains multiple computers that need network connectivity.
5. A repeater is required when the cable distance exceeds 100 meters in order to prevent signal degradation. Therefore, it should be positioned between sales to production and sales to service.
   Distances to consider:
   • Sales to production = 110 m (repeater required)
   • Sales to service = 135 m (repeater required)
