‘Swabhaav’ is a big NGO working in the field of Psychological Treatment and Counselling, having its Head Office in Nagpur. It is planning to set up a center in Vijayawada. The Vijayawada Center will have four blocks – ADMIN, PSYCHIATRY, PSYCHOLOGY, and ICU. You, as a Network Expert, need to suggest the best network-related solutions for them to resolve the issues/problems mentioned in questions (i) to (v), keeping the following parameters in mind: 
Question: 1

Solution and Explanation
The best location to place the server in the Vijayawada center is the PSYCHIATRY block.
This is because it has the highest number of computers — 40 systems,
which means more communication will happen from this block than any other.
Placing the server here reduces data traffic across long distances.
Additionally, this block is centrally positioned among all four blocks:
- Distance to ADMIN = 65m
- Distance to PSYCHOLOGY = 100m
- Distance to ICU = 50m
Therefore, server placement in PSYCHIATRY block ensures optimal speed and efficiency.

Question: 2
Which hardware device will you suggest to connect all the computers within each block of Vijayawada Center?
Which hardware device will you suggest to connect all the computers within each block of Vijayawada Center?
Show Hint
Use a switch to connect multiple computers in a block.
It is more efficient and secure than a hub.

Solution and Explanation
To connect computers within each block, a Switch is the best choice.
A switch is a Layer 2 device that connects multiple devices on a local area network (LAN).
It transfers data intelligently to the intended recipient using MAC address filtering.
This reduces collision and ensures smooth communication among devices.
Each block (like ADMIN, PSYCHIATRY, etc.) should have its own switch.

Question: 3
Draw a cable layout to efficiently connect various blocks within the Vijayawada Center.
Draw a cable layout to efficiently connect various blocks within the Vijayawada Center.
Show Hint
Use a star topology with the block having maximum systems as the central node
to reduce total wiring and improve network reliability.

Solution and Explanation
We must choose a layout that uses the shortest cable distances.
Let’s treat PSYCHIATRY as the central hub since it has the most computers and is centrally located.
The most efficient cabling will be:
- PSYCHIATRY to ADMIN = 65m
- PSYCHIATRY to PSYCHOLOGY = 100m
- PSYCHIATRY to ICU = 50m
This star topology minimizes cabling cost and simplifies troubleshooting.
All communication from other blocks can pass through the PSYCHIATRY block server.

Question: 4
Where should the router be placed to provide internet to all the computers in the Vijayawada Center?
Where should the router be placed to provide internet to all the computers in the Vijayawada Center?
Show Hint
Routers should be placed in central locations with high device density

Solution and Explanation
The router should be placed in the PSYCHIATRY block.
This is because it has the highest number of computers (40)
and also lies at the center of the network layout,
making it easily accessible to all other blocks.
All other blocks are within 100m of PSYCHIATRY, which is suitable for Ethernet cabling.
Placing the router here will ensure minimal cable length and maximum speed.

The Manager at Nagpur wants to remotely access the computer in Admin block in Vijayawada. Which protocol will be used for this?
The Manager at Nagpur wants to remotely access the computer in Admin block in Vijayawada. Which protocol will be used for this?
Show Hint
SSH is used for secure remote access to systems, especially over large distances.
It encrypts data to prevent eavesdropping during communication.

Solution and Explanation
The protocol that should be used is SSH (Secure Shell).
SSH allows encrypted remote login and command execution on computers.
It provides secure access over unsecured networks like the internet.
The Manager at Nagpur can use SSH to safely log into the Admin system in Vijayawada.
Alternative protocols such as RDP (Remote Desktop Protocol) are also used,
but SSH is preferred for secure and text-based administration.

Question: 6
Which type of Network (PAN, LAN, MAN or WAN) will be set up among the computers connected with Vijayawada Center?
Which type of Network (PAN, LAN, MAN or WAN) will be set up among the computers connected with Vijayawada Center?
Show Hint
Use LAN for computers within the same campus or building.
Use WAN for inter-city or inter-office communication over the internet.

Solution and Explanation
The correct type of network is LAN (Local Area Network).
All the computers in Vijayawada Center are located in nearby blocks of the same campus.
LAN is ideal for short-distance, high-speed communication within a limited area.
It is cheaper to install and manage compared to WAN or MAN.
For external connection between Vijayawada and Nagpur, WAN would be used,
but within Vijayawada, the setup is strictly a LAN.
