What are the EIGRP K value metrics?

Bandwidth, Latency, Load, Reliability, MTU
Bandwidth, Delay, Load, Reliability, MTU
Speed, Quality, Performance, Reliability, Capacity
Throughput, Delay, Load, Reliability, Bandwidth

The correct answer is: Bandwidth, Delay, Load, Reliability, MTU

The correct answer identifies the five K values used by EIGRP (Enhanced Interior Gateway Routing Protocol) to determine the best path for routing traffic. These K values are essential metrics that EIGRP uses to calculate its composite metric for routes. In this context, the accurate K values are: 1. Bandwidth: This reflects the maximum speed of the link, influencing how quickly data can be transmitted. 2. Delay: This measures the time it takes for a packet to traverse the link, impacting the response times experienced in the network. 3. Load: This indicates the current traffic load on the link, helping to assess utilization. 4. Reliability: This assesses the stability and error rates of the link, which can affect overall performance. 5. MTU (Maximum Transmission Unit): Although it assists in determining packet sizes and fragmentation considerations, it isn't traditionally considered one of the K values affecting routing decisions directly. This set of K values works together to create a formula EIGRP uses to compute the best routing paths, thus ensuring reliability and performance in route selection.
