reach the same destination via 6 different paths. All paths have the same metric and administrative distance.With all routers using the default operation,which of the paths will be chosen to reach the destination？（）

A. Only the first two paths that are learned.

B. Four of the paths.

C. All six routes in a routed robin fashion.

D. The oldest two paths in the routing table.

E. The first path learned to the destination network.

te command output on router R1 lists the following phrase: "Gateway of last resort is 1.1.1.1 to network 2.0.0.0".Whic h of the following is most likely to have caused this output to occur on R1？（）

A. R1 has been configured with an ip default- network 2.0.0.0 command.

B. R1 has been configured with an ip route 0.0.0.0 0.0.0.0 1.1.1.1 command.

C. R1 has been configured with an ip route 2.0.0.0 255.0.0.0 1.1.1.1 command.

D. Another router has been configured with an ip default - network 2.0.0.0 command.

E. Another router has been configured with an ip route 2.0.0.0 255.0.0.0 1.1.1.1 command.

A. You can reach other Level 2 routers.

B. It can reach at least one other defined area.

C. The router is reachable by at least two ES-IS nodes.

D. It has at least one enabled reachable prefix with a valid metric defined.

SPF and EIGRP, and their default metrics are configured the same. Router D has equal cost paths to networks where both paths are not r eally equal cost. For example, network 172.16.54.0 shows equal cost through both router B and router C, though in reality the cost is greater using router C. Other routers, though not shown, are connected to the 172.16.54.0 and 172.16.55.0 networks, and the same issues exist to those routers and the networks connected to them. What can be done so that data will be routed along the most optimal path in the network？ （）

A. Redistribute connected interfaces on router B and router C

B. Set the maximum nu mber of equal cost paths to1 in all routers

C. When redistributing EIGRP into OSPF, set the external metric type to type E1

D. Adjust the default metrics in router B and router C so that the values are different in each router

E. None of these solut ions will fix the problem. Migrate to a single dynamic routing protocol

rk. One route is from EIGRP and has a composite metric of 20514560. Another route is from OSPF with a metric of 782.The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table？（）

A.Router R2 will not form a neighbor relationship with R1.

B.Router R2 will obtain a full routing table, including a default route, from R1.

C.R2 will obtain OSPF updates from R1, but will not obtain a default route from R1.

D.R2 will not have a route for the directly connected serial network, but all other directly connected

en them. Each router has been configured with the appropriate network statements under router ospf 1, but the routers are not forming an adjacency. Which of the following three commands could be configured on each router to correct this problem？（）

A. RouterC(config - if)#ip ospf network broadcast RouterD(config - if)#ip ospf network broadcast

B. RouterC(config - if)#ip ospf network point - to - point RouterD(config - if)#ip ospf network point - to - point

C. RouterC(config - router)#neighbor 10.100. 100.4 RouterD(config - router)#neighbor 10.100.100.3

D. RouterC(config - router)#neighbor 10.255.255.254 RouterD(config - router)#neighbor 10.255.255.253

A. It routes all traffic that is addresses to the destination network to the interface indicates in the routing table.

B. It sends a copy of its neighbor table to all adjacent routers.

C. It sends a multicast query packet to all adjacent neighbors requesting available routing paths to the destination network.

D. It broadcasts Hello packets to all routers in the network to re-establish neighbor adjacencies.
