The EIGRP Test! Trivia Quiz

Explanation
This statement is false because EIGRP is actually a distance vector routing protocol, not a link-state routing protocol. EIGRP uses a combination of distance vector and link-state characteristics to determine the best path for routing. It maintains a topology table, but it does not use it in the same way as a pure link-state protocol like OSPF.

Explanation
EIGRP (Enhanced Interior Gateway Routing Protocol) is a routing protocol used in computer networks. The Neighbor Table is associated with EIGRP as it keeps track of neighboring routers. The Route Table is also associated with EIGRP as it stores the best routes to reach different network destinations. The Topology Table is another table associated with EIGRP, as it maintains a complete picture of the network's topology. Therefore, the correct answer is Neighbor Table, Route Table, and Topology Table.

Explanation
In a routing protocol, a backup route is called a feasible successor. A feasible successor is an alternative route to a destination that is considered as a backup in case the primary route fails. It is determined based on the feasibility condition, which states that the advertised distance of the feasible successor must be less than the total distance of the current best route. This ensures that the backup route is a viable alternative and can be quickly used if the primary route becomes unavailable.

Explanation
In the Active route state, a re-computation would be taking place. This means that the routing protocol is actively recalculating and updating the routing table based on changes in the network. The Active state is typically associated with link-state routing protocols, where routers exchange information about the network topology to determine the best path for forwarding packets. During a re-computation in the Active state, routers may exchange routing updates, recalculate routes, and update their routing tables accordingly.

Explanation
If a link or interface went down in EIGRP, the packet that would be sent out is a query. EIGRP uses queries to determine if any alternate paths are available when a link or interface fails. The query packet is broadcasted to neighboring routers to gather information about alternative routes. This helps EIGRP to quickly adapt to network changes and find the best available path to reach the destination.

Explanation
EIGRP uses the RTP (Reliable Transport Protocol) to deliver routing information. RTP is a protocol that provides reliable delivery of data packets in a network. It ensures that the routing information is transmitted accurately and efficiently between EIGRP routers. TCP/IP, UDP, and SSL are other protocols used in networking, but they are not specifically used by EIGRP for routing information delivery.

Explanation
EIGRP uses bandwidth and delay as the two component metrics to calculate the composite metric for a route. Bandwidth refers to the capacity of a link, while delay represents the time it takes for a packet to travel from source to destination. These two metrics are used by EIGRP to determine the best path for routing data packets. By considering both bandwidth and delay, EIGRP can select the most efficient and reliable route for data transmission.

Explanation
The EIGRP event log is the most important tool for troubleshooting or getting a view of what is happening in the network. It provides detailed information about EIGRP events such as neighbor changes, route updates, and errors. By analyzing the event log, network administrators can identify and resolve issues more effectively, ensuring the stability and performance of the network.

Explanation
Using stub routers and route summarization are two effective methods for limiting the EIGRP query range. Stub routers are configured to only advertise certain routes and do not participate in the query process, thus reducing the query range. Route summarization involves summarizing multiple routes into a single route, which also helps limit the query range by reducing the number of queries that need to be sent. These methods help optimize the EIGRP routing process and improve network performance.

Explanation
Yes, you can load share across two available paths even if they have different cost values. Load sharing is a technique used in network routing to distribute traffic across multiple paths. It allows for efficient utilization of network resources and can be implemented by assigning different weights or costs to each path. This means that paths with lower costs will carry more traffic, while paths with higher costs will carry less. Therefore, load sharing across paths with different cost values is possible.
