Refer to the exhibit.

A Boston company bought the 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 and 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.Add IP summary addresses to the Internet-pointing interfaces of routers N1 and B1.
• B.Turn off autosummarization on routers N1 and B1.
• C.Turn off auto summarization on routers N2 and B2.
• D.Add wildcard masks to the network commands on routers N2 and B2.

Which one of the following statements about BGP is FALSE?

• A.BGP uses TCP port 179.
• B.BGP uses notification and the update messages to establish and maintain the BGP neighbor relationship.
• C.BGP ensures reliability of updates by using the reliable transport services of TCP.
• D.The network command with the mask option never installs a prefix into the BGP table unless there is a matching prefix exists in the IP route table.
• E.A TCP connection is required before exchanging updates.

Refer to the exhibit.

A new TAC engineer came to you for advice. A GRE over IPsec tunnel was configured, but the tunnel is not coming up. What did the TAC engineer configure incorrectly?

• A.The crypto map configuration is not correct.
• B.The network 172.16.1.0 is not included in the OSPF process.
• C.The crypto isakmp configuration is not correct.
• D.The interface tunnel configuration is not correct.

You are developing a verification plan for an upcoming OSPF implementation. Part of this plan is to verify the status of type 3 LSAs within the network. Which routers should you verify first to ensure that the configurations are correct for generating type 3 LSAs?

• A.DRs and BDRs
• B.Internal routers within the NSSAs
• C.Internal routers within the stubby areas
• D.ABRs
• E.ASBRs
• F.Internal routers within the backbone area (area 0)

Refer to the exhibit and the partial configuration on router R2. On router R4 all RIP routes are
redistributed into the OSPF domain. A second redistribution is configured on router R2 using a route map. Based on the configuration on router R2, which EIGRP external routes will be present in the routing table of R1?

• A.all OSPF inter and intra-area routes
• B.all routes originating from RIP and OSPF routing domains
• C.the routes originating from the OSPF stub area
• D.the routes originating from the RIP routing domain
