Networking Components (Gateways, Routers) Questions and Answers for Viva

Answer-1: An edge router connects an internal network to external networks and often serves as the gateway.

Answer-2: Routers can filter traffic using access control lists (ACLs) and firewall capabilities.

Answer-3: A router that supports both 2.4GHz and 5GHz frequency bands for wireless communication.

Answer-4: It allows external devices to access services on a private network by mapping external ports to internal IP addresses and ports.

Answer-5: A device that combines a router and a wireless access point to provide internet and network access over Wi-Fi.

Answer-6: A modem connects to the internet through an ISP,while a router distributes that connection to multiple devices.

Answer-7: A physical device that routes traffic from a workstation to an outside network,often using protocol translation.

Answer-8: A software-based gateway runs on a server or VM to manage network traffic and protocol translation.

Answer-9: A gateway that translates different communication protocols to enable interoperability between systems.

Answer-10: It connects a traditional telephony network with a voice over IP (VoIP) network.

Answer-11: It manages API requests,routing,and security between clients and backend services in cloud applications.

Answer-12: It connects home devices to the internet,often integrating routing,firewall,and Wi-Fi functionalities.

Answer-13: A packet is a small segment of data sent over a network,containing source and destination addresses.

Answer-14: It determines the best path for data through a network based on metrics like distance or speed.

Answer-15: A distance-vector routing protocol that uses hop count as a routing metric.

Answer-16: A link-state routing protocol that uses path cost to determine the best route.

Answer-17: A path-vector routing protocol used to exchange routing information between autonomous systems on the internet.

Answer-18: A route that is used by a router when no other specific route is available for a destination.

Answer-19: Latency refers to the delay in data transmission between source and destination due to routing paths.

Answer-20: It is the IP address of the router or gateway that a device uses to send data outside its local network.

Answer-21: A condition where data packets circulate endlessly due to incorrect routing tables.

Answer-22: By using protocols like HSRP,VRRP,or GLBP to ensure backup routers take over if a primary router fails.

Answer-23: Combining multiple network connections in parallel to increase throughput and provide redundancy.

Answer-24: A software-based routing solution running on a virtual machine or container.

Answer-25: High-capacity routers used in large networks with advanced features like VPN support,firewall,and QoS.

Answer-26: It dynamically assigns IP addresses and other network configurations to devices in the network.

Answer-27: DNS translates domain names to IP addresses so that routers can forward data to the correct destination.

Answer-28: Quality of Service prioritizes certain types of traffic to ensure performance for critical applications.

Answer-29: Routers do not use MAC address tables; those are used by switches. Routers use IP addresses.

Answer-30: A built-in feature that monitors and filters incoming and outgoing traffic based on security rules.

Answer-31: Internet Control Message Protocol is used for sending error messages and operational information,such as ping.

Answer-32: Time To Live is a value that limits the lifespan of a packet in a network to prevent infinite looping.

Answer-33: Maximum Transmission Unit is the largest size packet or frame that can be sent over a network medium.

Answer-34: Combining multiple routes into a single advertisement to simplify routing tables.

Answer-35: A Virtual Local Area Network segments a network logically to enhance security and performance.

Answer-36: A type of NAT that maps multiple private IP addresses to a single public IP using different ports.

Answer-37: By queuing packets,implementing QoS,or rerouting traffic to balance the load.

Answer-38: LAN routing is for local networks,while WAN routing connects geographically dispersed networks.

Answer-39: A router is a networking device that forwards data packets between computer networks based on their destination IP address.

Answer-40: A gateway acts as a bridge between different networks using different protocols and is used to connect internal networks to external networks like the internet.

Answer-41: To determine the best path for forwarding packets to their destination across multiple networks.

Answer-42: A router connects multiple networks and uses IP addresses,while a switch connects devices within the same network and uses MAC addresses.

Answer-43: Yes,in many small networks,the router also acts as the default gateway to the internet.

Answer-44: Network Address Translation (NAT) is used by routers to map private IP addresses to a public IP address.

Answer-45: It serves as the forwarding host to access another network when no specific route is available in the routing table.

Answer-46: A routing table is a data table stored in a router or gateway that lists the routes to particular network destinations.

Answer-47: Static routing involves manually entering routes into the routing table.

Answer-48: Dynamic routing uses protocols to automatically update routing tables based on network changes.

Answer-49: OSPF,BGP,and RIP are common dynamic routing protocols.

Answer-50: A core router is designed to operate within the backbone or core of the internet,routing data within a large network.
