Cisco 300-320 Free Practice Questions

Q1. Which of the following is true regarding the effect of EIGRP queries on the network design? 

A. EIGRP queries will be the most significant issue with respect to stability and convergence 

B. EIGRP queries are not a consideration as long as EIGRP has a feasible successor with a next hop AD that is greater than the FD of the current successor route 

C. EIGRP queries will only increase the convergence time when there are no EIGRP stubs designed in the network
