   A router receives an EIGRP update for a route from a neighbor. The update includes a reported distance of 500. The local router's metric to reach that neighbor is 100. What is the feasible distance for this route?

   • A100
   • B500
   • C400
   • D600

   During an EIGRP convergence event, a router sends a query to all neighbors and waits for replies. One neighbor does not reply within the active timer. What happens?

   • AThe router sends a new query to the same neighbor with a higher sequence number.
   • BThe router continues to wait indefinitely for the reply.
   • CThe router declares the neighbor down and removes all routes learned from it.
   • DThe router marks the route as passive and uses the feasible successor.

   A network has three routers: R1, R2, and R3. R1 is connected to R2 and R3. R2 is connected to R3. All routers run EIGRP. The route to 10.1.1.0/24 is learned via R2 with a feasible distance of 1000 and via R3 with a feasible distance of 1200. R2's reported distance is 900, and R3's reported distance is 1100. R1's metric to R2 is 100, and to R3 is 100. R2 and R3 are also directly connected. If R2 fails, what is the impact on R1's route to 10.1.1.0/24?

   • AR1 flushes the route and waits for a new update from R3.
   • BR1 enters active state and sends queries to R3, because R3 is not a feasible successor.
   • CR1 immediately uses R3 as the new successor because R3 is a feasible successor.
   • DR1 immediately uses R3 as the new successor because it has the lowest feasible distance after R2.

   A large enterprise network uses EIGRP as the IGP. The network has a core layer and multiple distribution layers. The engineer wants to improve convergence time and reduce the impact of a link failure in the distribution layer. The engineer is considering the following options: 1) Configure all distribution routers as EIGRP stubs. 2) Implement route summarization on the core routers. 3) Adjust the EIGRP timers to be more aggressive. 4) Increase the variance to enable load balancing. Which combination of options will most effectively improve convergence and reduce query propagation?

   • A1 and 2
   • B3 and 4
   • C1 and 4
   • D2 and 3

   An engineer is configuring EIGRP named mode on a router that connects to two different service providers. The engineer wants to use different K-values for each provider link to influence path selection. However, the engineer also wants to enable unequal-cost load balancing across both links. What is the correct approach?

   • AConfigure the same K-values on both links, and use interface delay and bandwidth to influence the metric.
   • BUse the 'metric weights' command under the interface configuration to set different K-values per interface.
   • CConfigure different K-values per address-family, but this will affect all interfaces in that address-family.
   • DUse separate EIGRP instances for each provider link, each with its own K-values and variance.
