Wish Net Interview Questions and Answers

SFP stands for Small Form-factor Pluggable, a compact transceiver used in networking devices. Losses in optical fiber refer to the reduction in signal strength as light travels through the fiber.

• SFP is a hot-swappable transceiver used in networking equipment to transmit and receive data over optical fiber or copper cables.

• Losses in optical fiber can occur due to factors like bending, splicing, and impurities in the fib...read more

Optical Time Domain Reflectometer

• OTDR stands for Optical Time Domain Reflectometer

• It is a device used to test the integrity of fiber optic cables

• OTDR sends a pulse of light down the fiber and measures the reflections to determine the quality of the cable

• It is commonly used in network field engineering for troubleshooting and maintenance

Token passing is a network protocol for managing access to a shared communication medium.

• In token passing, a 'token' circulates in the network, granting permission to transmit data.

• Only the device holding the token can send data, preventing collisions.

• Examples include Token Ring and Fiber Distributed Data Interface (FDDI) networks.

• If a device does not need to send data, it passes the token to the next device.

A network is a collection of devices; networking is the process of connecting and managing those devices.

• A network refers to the actual infrastructure, like routers and switches.

• Networking involves the protocols and processes that allow devices to communicate.

• Example of a network: A local area network (LAN) in an office.

• Example of networking: Configuring IP addresses and managing data flow.

The OSI model is a conceptual framework used to understand network communication in seven layers.

• Layer 1: Physical - Deals with the physical connection (e.g., cables, switches).

• Layer 2: Data Link - Manages node-to-node data transfer (e.g., Ethernet).

• Layer 3: Network - Handles routing of data (e.g., IP addresses).

• Layer 4: Transport - Ensures complete data transfer (e.g., TCP, UDP).

• Layer 5: Session - Manages sessions bet...read more

Yes, I can configure a home router by accessing its settings through a web interface and adjusting various parameters.

• Connect your computer to the router via Ethernet or Wi-Fi.

• Open a web browser and enter the router's IP address (commonly 192.168.1.1 or 192.168.0.1).

• Log in using the default credentials (often found on the router or in the manual).

• Change the SSID (network name) and password for Wi-Fi security.

• Configure ...read more

• I have the necessary skills and experience for the role.

• I am available to start immediately without any prior commitments.

• I am motivated by the opportunity and financial incentive.

• I can quickly adapt to the work environment and team.

The colour code of twisted pair cables is used to identify the different pairs of wires within the cable.

• The most common colour code for twisted pair cables is the TIA/EIA 568 standard, which uses the following colours: white/blue, blue, white/orange, orange, white/green, green, white/brown, brown.

• The colour code helps technicians easily identify and match the correct pairs of wires when terminating the cable.

• Using the...read more
