Refer to the exhibit. Looking at the topology diagram and the partial router configurations shown, which statement is true? （）
A.The NProuter has two OSPF neighbors in the "Full" adjacency state
B.The NProuter serial0/0 interface has the OSPF dead timer set to 10 seconds
C.The NProuter serial0/0 interface has been configured with an OSPF network type of "pointtopoint"
D.The 10.1.1.1 and 10.1.1.2 routers are not using the default OSPF dead and hello timers setting
E.The "Mismatched" error is caus ed by the expiration of the OSPF timers
Refer to the exhibit. A Boston company bought the asse ts of a New York company and is trying to route traffic between the two data networks using EIGRP over EoMPLS. As a network consultant, you were asked to verify the interoperability of the two networks. From the show ip route command output, what can yo u tell the customer about the traffic flow between the subnet in New York (172.16.8.0/24) and the subnets in Boston (172.16.16.0/24 and 10.10.16.0/24)?（）
A. Traffic is flowing between the 172.16.8.0 subnet and subnets 172.16.16.0 and 10.10.16.0 and no configuration changes are needed.
B. Auto - summary must be disabled on N1 and B1 before traffic can flow between the 172.16.8.0 subnet and subnets 172.16.16.0 and 10.10.16.0.
C. Traffic will flow between the 172.16.8.0 subnet and 172.16.16.0 without any further configuration changes. However, auto - summary must be disabled on N1 and B1 before traffic can flow between the 172.16.8.0 subnet and the 10.10.16.0 subnet.
D. Auto - summary must be disabled on N1 and B1 before traffic can flow between the 172.16 .8.0 subnet and the 172.16.16.0 subnet. However, traffic will flow between the 172.16.8.0 subnet and 10.10.16.0 without any further configuration changes.
Refer to the exhibit. A Boston company bought th e assets of a New York company and is trying to route traffic between the two data networks using EIGRP. The show command output shows that traffic will not flow between the networks. As a network consultant, you were asked to modify the configuration a nd certify the interoperability of the two networks. For traffic to flow from subnet 172.16.8.0/24 to the 172.16.16.0/24 subnet, which configuration change do you recommend?（）
A. Turn off autosummarization on routers N1 and B1.
B. Add IP summary addre sses to the Internet - pointing interfaces of routers N1 and B1.
C. Turn off autosummarization on routers N2 and B2.
D. Add wildcard masks to the network commands on routers N2 and B2.
Refer to the exhibit.The actual speed of the serial links between R2 and R3 are 256 kb/s and 512k b/s respectively. When configuring EIGRP on routers R2 and R3, the network administrator configured the bandwidth of both serial interfaces to 512 kb/s. What will be the effect?（）
A. EIGRP will overutilize the 512 kb/s link.
B. The interface "delay" value used in the EIGRP metric calculation will be inaccurate on the 256k b/s serial interface.
C. The amount of bandwidth used for EIGRP routing protocol traffic on the 256 kb/s link can become excessive.
D. EIGRP can load balance between the two serial links only if the variance is set to 2 or higher.
E. Unequal cost load balancing will be disabled.
