Router R1 lists 4 routes for subnet 10.1.1.0/24 in the output of the show ip eigrp topology all - links command. The variance 200 command is configured, but no other related commands are configured. Which of the following rules are true regarding R1‘s decision of what r outes to add to the IP routing table?Note that RD refers to reported distance and FD to feasible distanc E.（）A. Adds all routes for which the metric is = 200 * the best metric among all routesB. Adds all routes because of the ridiculously high variance settingC. Adds all successor and feasible successor routesD. Adds all successor and feasible successor routes for which the metric is=200 * the best metric among all routes
Refer to the exhibit. EIGRP has been configured on al l routers in the network. The command metric weights 0 0 1 0 0 has been added to the EIGRP process so that only the delay metric is used in the path calculations. Which router will R1 select as the successor and feasible successor for Network A?（）A. R 4 becomes the successor for Network A and will be placed in the routing table. R2 becomes the feasible successor for Network AB. R4 becomes the successor for Network A and will be included in the routing table. No feasible successor will be selected a s the advertised distance from R2 is higher than the feasible distanceC. R2 becomes the successor and will be placed in the routing table. R4 becomes the feasible successor for Network AD. R2 becomes the successor and will be placed in the routing t able. No feasible successor will be selected as the reported distance from R4 is lower than the feasible distance
Refer to the exhibit. EIGRP has been configured on router D. Router C is performing mutual redistribution between EI GRP and OSPF. While verifying that the redistribution is functioning properly, you discover that while router C has all of the EIGRP routes in its routing table, router A does not have any routes from the EIGRP domain. What on router C may be the cause o f the problem?（）A. The no auto - summary command needs to be added under router eigrp 1B. The subnets keyword was not included in the redistribute command under router ospf 1C. The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router AD. The default - information originate command needs to be added under router ospf 1E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF
