Which of the following answers correctly identifies a value that feeds into the EIGRP metric calculation?

Router R1 is three router hops away from subnet 10.1.1.0/24. According to various show
interfaces commands, all three links between R1 and 10.1.1.0/24 use the following settings:

bandwidth: 1000, 500, 100000 and delay: 12000, 8000, 100. Which of the following answers
correctly identifies a value that feeds into the EIGRP metric calculation? (Choose two correct
answers.)

A.
Bandwidth of 101,500

B.
Bandwidth of about 34,000

C.
Bandwidth of 500

D.
Delay of 1200

E.
Delay of 2010

F.
Delay of 20100

Explanation:
The EIGRP metric calculation treats bandwidth and delay differently. For
bandwidth, EIGRP takes the lowest bandwidth, in Kbps, which is in this case 500
Kbps. For delay, EIGRP takes the cumulative delay, which is 20100 per the various
show interfaces commands. However, the show interfaces command uses a unit of
microseconds, and the interface delay command, and the EIGRP metric formula uses
a unit of tens-of-microseconds, making the delay that feeds into the formula be 2010.

    1. Lucas says:

      Delay is calculed in tens-of-microseconds, then add 0 in finally, ex: if you set a Delay in 100, when you show ip eigrp interface you see 1000 in the value.That is why use 2010 instead 20100.
