10+ Interview Questions and Answers

A network is a group of interconnected devices that communicate with each other to share resources and information.

• A network can be wired or wireless

• Devices on a network can include computers, printers, routers, and switches

• Networks can be local (LAN) or wide area (WAN)

• Switches are devices that connect devices on a network and direct traffic between them

PPPoE is a protocol used to connect devices to the internet through a DSL line. WAN stands for Wide Area Network. Routers are configured to connect devices to the internet.

• PPPoE stands for Point-to-Point Protocol over Ethernet

• It is used to establish a connection between a device and an ISP through a DSL line

• WAN is a network that covers a large geographical area, such as the internet

• Routers are configured with settings such as IP address, subnet mask, default gateway, and DNS ...read more

A power battery switch is a device used to control the flow of power from a battery to a circuit or device.

• It is typically used in situations where multiple batteries are connected to a circuit and need to be switched on or off.

• The switch allows for easy control and management of power sources.

• Examples include battery backup systems for network equipment, where the switch determines whether power is sourced from the main power supply or the backup battery.

• Power battery switch...read more

Optical fiber splicing is the process of joining two fiber optic cables together.

• Splicing is done to extend the length of a fiber optic cable or to repair a damaged cable.

• There are two types of splicing: fusion splicing and mechanical splicing.

• Fusion splicing involves melting the ends of two fibers together using an electric arc.

• Mechanical splicing involves aligning the two fibers and holding them together with a splice connector.

• Splicing requires specialized equipment and tr...read more

IPv4 is the fourth version of the Internet Protocol, used to identify devices on a network. An upgrade is needed due to the limited number of available IP addresses.

• IPv4 uses 32-bit addresses, allowing for approximately 4.3 billion unique addresses.

• With the increasing number of devices connected to the internet, the available IPv4 addresses are running out.

• IPv6 is the upgraded version of the protocol, using 128-bit addresses to provide a vastly larger pool of unique addresses...read more

Router's and switches configuration system problems can be resolved by troubleshooting, updating firmware, checking cables, and resetting to factory settings.

• Troubleshoot the network connectivity issues by checking cables and connections

• Update the firmware of the router or switch to the latest version

• Reset the router or switch to factory settings if necessary

• Check for any configuration errors in the device settings

Fiber connectivity refers to the use of fiber optic cables to transmit data at high speeds over long distances.

• Fiber optic cables use light to transmit data, allowing for faster speeds and greater bandwidth compared to traditional copper cables.

• Fiber connectivity is commonly used in networking infrastructure for its reliability and high performance.

• Examples of fiber connectivity applications include long-distance telecommunications, data centers, and high-speed internet conne...read more

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

• Networks can be classified based on their size (LAN, WAN, MAN)

• Networks can be wired (Ethernet, fiber optic) or wireless (Wi-Fi, Bluetooth)

• Network protocols like TCP/IP govern how data is transmitted across networks

• Network security measures like firewalls and encryption protect data from unauthorized access

• Examples of netw...read more
