Correct Answer : Option (A) :   DUAL

Explanation : EIGRP uses the DUAL algorithm for finding shortest path. DUAL stands for diffusing update algorithm and it is used to prevent routing loops by recalculating routes globally.

Q .
Administrative distance for external EIGRP route is _______
A)
100
B)
170
C)
135
D)
190

Correct Answer : Option (B) :   170
