CCNP ROUTE (Version 6.0) Chapter 7 Exam Answers

Assessment – ROUTE Chapter 7 – CCNP ROUTE (Version 6.0) Exam Answers

1. Refer to the exhibit. A network administrator has configured a GRE tunnel between R1 and R2 as shown. After completing the tunnel configurations, the administrator notices that the tunnel interfaces on both routers are down. All other interfaces are up and the pings through the ISP to the serial interface of each router are successful. What is the cause of the problem?

• Tunnel source configurations are incorrect.

• Generic Routing Encapsulation (protocol 47)
• Encapsulating Security Protocol (protocol 50)
• Internet Security Association and Key Management Protocol (TCP port 500)
• Internet Security Association and Key Management Protocol (UDP port 500)

3. Refer to the exhibit. Based on the partial configuration that is shown, which static route would be the primary default path?

5. Which two statements are correct about IPsec crypto maps? (Choose two.)

• The crypto map defines the IPsec tunnel endpoint or peer.
• Packets that do not meet the criteria as specified in the crypto map are dropped.
• The crypto map is applied to the outbound interface that the router is peering with.
• A crypto map is used to negotiate and exchange authentication and encryption parameters with its peer.
• The crypto map is applied to the inbound interface that receives the packets before being transmitted over the VPN tunnel.

6. What is a limitation of IPsec by design?

• IPsec only forwards unicast traffic.
• IPsec does not support encryption for traffic over a GRE tunnel.
• IPsec forwards unicast and multicast traffic, but not broadcast traffic.
• IPsec tunneling does not support the encapsulation of RFC 1918 addresses.

7. Refer to the exhibit. Which two statements are true about the exhibited static routes? (Choose two.)

• If a route to 10.0.0.0/8 is received via RIP, R1 will prefer the dynamic route over both configured static routes.
• If no dynamic route to 10.0.0.0/8 exists, both static routes will appear in the R1 routing table.
• If no dynamic route to 10.0.0.0/8 exists, R1 will use 2.2.2.2 as the next hop because it has a higher preference.
• If a route to 10.0.0.0/8 is received via RIP, both static routes will appear in the routing table.
• The static route to 10.0.0.0/8 via 1.1.1.1 will be preferred to the route via 2.2.2.2.

8. Refer to the exhibit. A network administrator is configuring NAT on router Remote. The configuration should allow users on network 172.16.16.0/21 to access Internet sites as well as resources on the HQ LAN network 172.16.0.0/21 through the VPN tunnel. How should the administrator configure access list 101 to accomplish this task?

• Remote(config)# access-list 101 deny 172.16.16.0 0.0.7.255 172.16.0.0 0.0.7.255
  Remote(config)# access-list 101 permit ip 172.16.16.0 0.0.7.255 any
• Remote(config)# access-list 101 permit ip 172.16.16.0 0.0.7.255 any
  Remote(config)# access-list 101 deny 172.16.16.0 0.0.7.255 172.16.0.0 0.0.7.255
• Remote(config)# access-list 101 deny 172.16.16.0 0.0.7.255 any
  Remote(config)# access-list 101 permit ip 172.16.16.0 0.0.7.255 any
• Remote(config)# access-list 101 deny 172.16.16.0 0.0.7.255 209.165.202.129 0.0.0.3
  Remote(config)# access-list 101 permit ip 172.16.16.0 0.0.7.255 any
• Remote(config)# access-list 101 permit ip 172.16.16.0 0.0.7.255 any
  Remote(config)# access-list 101 deny 172.16.0.0 0.0.7.255 172.16.16.0 0.0.7.255

9. How is NAT tuned to handle traffic that is sent through a VPN tunnel between a mobile worker and internal corporate resources?

• Translation is allowed by a permit access list statement or route map.
• Translation is allowed by a deny access list statement or route map.
• Traffic should bypass translation with a permit access list statement or route-map.
• Traffic should bypass translation with a deny access list statement or route-map.
