Reliance Communications Interview Questions and Answers

A network is a collection of interconnected devices that communicate and share resources.

• Networks can be wired (e.g., Ethernet) or wireless (e.g., Wi-Fi).

• They enable resource sharing, such as printers and files.

• Common types include LAN (Local Area Network) and WAN (Wide Area Network).

• Protocols like TCP/IP govern data transmission across networks.

• Examples include home networks connecting computers and smartphones.

Switch configuration involves setting up network switches for optimal performance and security using various methods.

• Access the switch via console, SSH, or web interface.

• Use command-line interface (CLI) commands to configure settings.

• Set up VLANs to segment network traffic (e.g., 'vlan 10' for a specific VLAN).

• Configure port settings, such as speed and duplex (e.g., 'interface gig0/1' followed by 'speed 1000').

A VLAN (Virtual Local Area Network) segments a physical network into multiple logical networks for improved management and security.

• Improves network performance by reducing broadcast domains.

• Enhances security by isolating sensitive data traffic (e.g., finance department).

• Facilitates easier network management and organization (e.g., grouping users by department).

• Allows for better resource allocation and traffic pri...read more

TCP is connection-oriented and reliable, while UDP is connectionless and faster but less reliable.

• TCP establishes a connection before data transfer, ensuring reliability.

• UDP sends data without establishing a connection, making it faster but less reliable.

• TCP guarantees data delivery and order, while UDP does not guarantee delivery or order.

• Examples: TCP is used for web browsing (HTTP), while UDP is used for video ...read more

A ton in air conditioning refers to the cooling capacity of an air conditioning system.

• A ton in air conditioning is a unit of measurement for cooling capacity, representing the amount of heat needed to melt one ton of ice in a 24-hour period.

• One ton of cooling is equal to 12,000 British Thermal Units (BTUs) per hour.

• For example, a 2-ton air conditioner can remove 24,000 BTUs of heat per hour from a space.

Telecommunication sector primarily runs on DC power.

• Telecommunication sector uses DC power for its equipment and infrastructure.

• DC power is more stable and reliable for long-distance transmission of signals.

• AC power may be used in some parts of the telecommunication network for specific purposes.

• Examples of DC-powered devices in the telecommunication sector include routers, switches, and base stations.

Administrative Distance (AD) is a value that rates the trustworthiness of routing information from different protocols.

• AD is used by routers to select the best path when multiple routes exist.

• Lower AD values indicate more trusted routes; for example, OSPF has an AD of 110.

• Static routes have an AD of 1, making them the most trusted.

• RIP has an AD of 120, which is higher than OSPF, indicating less trust.

• The default A...read more
