List of Questions5 questions
- Question 1
- To match specific bits of a destination IP address for forwarding.
- To route packets only to directly connected networks.
- To specify a next-hop router for all destination IP addresses.
- To provide a static route for all remote networks.
- Question 2
- The router immediately drops the packet if it's not for a directly connected network.
- The router examines the destination MAC address in the packet header.
- The router encapsulates the packet and forwards it without checking the routing table.
- The router checks its IP routing table for the longest matching prefix.
- Question 3
- Automatically through dynamic routing protocols.
- Manually configured by the network administrator.
- Only when routing decisions require them.
- When a local interface is active without an IP address.
- Question 4
- The packet is queued for later processing.
- The packet is sent to all configured interfaces.
- The packet is dropped.
- The packet is forwarded to the next available router.
- Question 5
- Each router makes its forwarding decision based solely on its own routing table
- Routers rely on a centralized database for routing information
- Routers can see the routing tables of all other routers directly
- Routing decisions are made collaboratively among all routers

- Card 1HintRouter chooses the route with the most specific network address to forward packets. Memory TipThink "most specific" route.
- Card 2HintA general route for any destination not explicitly defined. Memory TipLast resort route
- Card 3HintThis table determines where to send a packet.Memory TipRouter's map for packet delivery
- Card 4HintCheck the table to know which outgoing interface is appropriate.Memory TipPacket delivery instructions
- Card 5HintRouter automatically learns about these networks.Memory TipThe immediate network
- Card 6HintImagine each router has a map, but they don't share their maps with each other, only comparing notes occasionally.Memory TipIndependent routers, independent maps
- Card 7HintThink of a table with columns for destination, next hop, interface, and route quality.Memory TipTable with destination details
- Card 8HintImagine a source ranking - trusted sources have lower scores, less trustworthy ones have higher scores.Memory TipLower score, higher trust
- Card 9HintThink of it like the cost of a road trip - shorter and faster routes have lower scores.Memory TipLower cost, better route
- Card 10HintThink of the next-hop as the next address on the map you need to travel towards.Memory TipNext step on the route
