‘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

Suggest the most appropriate location of the server inside the Vijayawada Center. Justify your choice.

Show Hint

Choose the block with the highest number of computers and central distance for server placement
to minimize network traffic and improve performance.
Updated On: Jan 14, 2026
Show Solution

Solution and Explanation

The optimal location for the server at the Vijayawada center is the PSYCHIATRY block. This decision is based on its highest computer density, with 40 systems, facilitating greater communication volume. Locating the server here minimizes long-distance data traffic. Furthermore, the block's central position relative to other blocks, with distances of 65m to ADMIN, 100m to PSYCHOLOGY, and 50m to ICU, supports efficient data flow. Consequently, server deployment in the PSYCHIATRY block guarantees peak performance and efficiency.

Question: 2

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.
Updated On: Jan 14, 2026
Show Solution

Solution and Explanation

For inter-computer connectivity within each block, a Switch is the optimal solution.
A switch operates at Layer 2, facilitating the connection of multiple devices across a local area network (LAN).
It efficiently directs data to its specific destination by employing MAC address filtering.
This mechanism minimizes data collisions, thereby guaranteeing seamless communication between devices.
Each distinct block, such as ADMIN or PSYCHIATRY, requires its dedicated switch.

Question: 3

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.
Updated On: Jan 14, 2026
Show Solution

Solution and Explanation

To minimize cable lengths, we will select a layout with PSYCHIATRY as the central hub due to its high computer density and central location.
The optimal cabling configuration is as follows:
- PSYCHIATRY to ADMIN: 65m
- PSYCHIATRY to PSYCHOLOGY: 100m
- PSYCHIATRY to ICU: 50m
This star topology approach will reduce cabling expenses and facilitate easier troubleshooting.
All traffic from other departments will be routed through the PSYCHIATRY block server.

Question: 4

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
to ensure efficient internet distribution across all network nodes.
Updated On: Jan 14, 2026
Show Solution

Solution and Explanation

The router's optimal location is the PSYCHIATRY block.
This decision is based on it hosting the highest number of computers (40)
and its central position within the network layout,
facilitating easy access for all other blocks.
With all other blocks within 100m of PSYCHIATRY, Ethernet cabling requirements are met.
This placement guarantees minimal cable length and optimal speed.

Question: 5

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.
Updated On: Jan 14, 2026
Show Solution

Solution and Explanation

The recommended protocol is SSH (Secure Shell).
SSH facilitates encrypted remote login and command execution.
It ensures secure connectivity across unsecured networks, including the internet.
The Nagpur Manager can utilize SSH for secure access to the Vijayawada Admin system.
While alternatives like RDP (Remote Desktop Protocol) exist,
SSH is favored for secure, text-based administrative tasks.

Question: 6

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.
Updated On: Jan 14, 2026
Show Solution

Solution and Explanation

The appropriate network type is a Local Area Network (LAN).
Computers at the Vijayawada Center are situated in adjacent blocks on the same campus.
LANs facilitate high-speed communication over short distances within a confined area.
Installation and management costs are lower for LANs than for WANs or MANs.
While a Wide Area Network (WAN) would connect Vijayawada and Nagpur externally,
the internal network within Vijayawada is exclusively a LAN.
