2.單項(xiàng)選擇題What is the purpose of configuring router R1 with the "IP Helper address" command?()

A.IP Helper is used to direct BOOTP clients to a BOOTP server
B.IP Helper is used to prevent the router form forwarding IP broadcasts
C.IP Helper is used to allow IPX clients to communicate with IP-based servers
D.IP Helper is used to accommodate compatibility routers using different IP routing protocols

RIP and OSPF are configured on the routers as shown in the exhibit. R2 is configured with a two-way redistribution between RIP and OSPF domains. All routers can ping each other, but R1cannot see any of the OSPF routes in its routing table. What could the problem be?()

A.OSPF and RIP use the same major network 172.16.0.0. Therefore, the keywordsubnets is notrequired to redistribute protocols into OSPF
B.Because OSPF has a longer mask for the same major network than RIP and because RIPversion 1 is being used, none of the routes learned from OSPF will be advertised into RIP
C.The metric for the OSPF routes that are redistributed into RIP is too low, a fact that preventsOSPF routes from being advertised into RIP
D.The process of redistribution of RIP into OSPF does not require any metric conversion, so thereis no need to define the metric using the default-metric command during the redistribution

Refer to the network shown below:

R1 and R2 belong to the RIP routing domain that includes the networks 10.20.0.0/16 and
10.21.0.0/16. R3 and R4 are performing two-way route redistribution between OSPF and RIP. Anetwork administrator has discovered that R2 is receiving OSPF routes for the networks
10.20.0.0/16 and 10.21.0.0/16 and a routing loop has occurred. Which action will correct thisproblem?()

A.Set the OSPF default metric to 20
B.Apply an inbound ACL to the R2 serial interface
C.Configure distribute-lists on R3 and R4
D.Change the RIP administrative distance on R3 to 110
E.Change the OSPF administrative distance on R3 to 110
F.None of the other alternatives apply
