Securelynkx Networks Interview Questions, Process, and Tips

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

• The OSI model stands for Open Systems Interconnection model.

• It helps in understanding how different networking protocols work together.

• The seven layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer has specific functions and communicates w...read more

Root bridge election is the process by which switches in a network determine which switch will be the root bridge.

• Root bridge is the central bridge in a spanning tree network

• Switches exchange bridge protocol data units (BPDUs) to elect the root bridge

• The switch with the lowest bridge ID becomes the root bridge

• Root bridge election helps in determining the best path for data transmission

Networking devices are hardware devices that are used to connect computers and other devices to create a network.

• Networking devices include routers, switches, hubs, modems, access points, and network adapters.

• Routers are used to connect multiple networks together and route data between them.

• Switches are used to connect devices within a network and manage the traffic between them.

• Hubs are basic networking devices that c...read more

An IP address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.

• IP addresses are used to identify and locate devices on a network

• There are two types of IP addresses - IPv4 and IPv6

• IPv4 addresses are 32-bit numbers written in decimal format (e.g. 192.168.1.1)

• IPv6 addresses are 128-bit numbers written in hexadecimal format (e.g. 2001:0db8

DHCP (Dynamic Host Configuration Protocol) assigns IP addresses to devices on a network, while DNS (Domain Name System) translates domain names to IP addresses.

• DHCP dynamically assigns IP addresses to devices on a network

• DNS translates domain names to IP addresses

• I have experience configuring DHCP and DNS servers in network setups

I am currently earning $80,000 per year.

• My current salary is $80,000 per year.

• I am satisfied with my current salary.

• I am open to discussing salary expectations for this role.

A network is a collection of computers, servers, mainframes, network devices, and other devices connected to one another for sharing data and resources.

• Network is a group of interconnected devices that can communicate with each other.

• Devices in a network can include computers, servers, routers, switches, and more.

• Networks can be wired or wireless, local (LAN) or wide area (WAN), and can be private or public.

• Examples of...read more

DHCP stands for Dynamic Host Configuration Protocol, used to automatically assign IP addresses to devices on a network.

• DHCP eliminates the need for manual IP address configuration

• It assigns IP addresses dynamically to devices when they connect to the network

• DHCP servers manage a pool of IP addresses and lease them to devices for a specific period of time

• Example: When you connect your laptop to a Wi-Fi network, DHCP ass

OSI model is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system. Transport layer is responsible for end-to-end communication between applications.

• OSI model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Transport layer provides reliable and sequential delivery of data between end systems.

• It ensures ...read more

The network layer is responsible for logical addressing and routing of data packets across different networks.

• Network layer is the third layer of the OSI model.

• It provides logical addressing to devices on the network.

• IP (Internet Protocol) is a commonly used protocol at this layer.

• Routing protocols like OSPF and BGP operate at this layer.

• Network layer devices include routers and layer 3 switches.
