Modules 14 – 16: Routing Concepts and Configuration Exam Answers Switching, Routing, and Wireless Essentials ( Version 7.00) – Routing Concepts and Configuration Exam 1. Which feature on a Cisco router permits the forwarding of traffic for which there is no specific route?  next-hop  gateway of last resort  route source  outgoing interface 2. Which three advantages are provided by static routing? (Choose three.)  Static routing does not advertise over the network, thus providing better security.  Configuration of static routes is error-free.  Static routes scale well as the network grows.  Static routing typically uses less network bandwidth and fewer CPU operations than dynamic routing does.  The path a static route uses to send data is known.  No intervention is required to maintain changing route information. 3. What are two functions of dynamic routing protocols? (Choose two.)  to maintain routing tables  to assure low router overhead  to avoid exposing network information  to discover the network  to choose the path that is specified by the administrator 4. What is an advantage of using dynamic routing protocols instead of static routing?  easier to implement  more secure in controlling routing updates  fewer router resource overhead requirements  ability to actively search for new routes if the current path becomes unavailable 5. What happens to a static route entry in a routing table when the outgoing interface associated with that route goes into the down state?

 The static route is removed from the routing table.  The router polls neighbors for a replacement route.  The router automatically redirects the static route to use another interface.  The static route remains in the table because it was defined as static. 6. What is a characteristic of a static route that matches all packets?  It uses a single network address to send multiple static routes to one destination address.  It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.  It backs up a route already discovered by a dynamic routing protocol.  It is configured with a higher administrative distance than the original dynamic routing protocol has. 7. When would it be more beneficial to use a dynamic routing protocol instead of static routing?  in an organization where routers suffer from performance issues  on a stub network that has a single exit point  in an organization with a smaller network that is not expected to grow in size  on a network where there is a lot of topology changes 8. Which route would be used to forward a packet with a source IP address of 192.168.10.1 and a destination IP address of 10.1.1.1?  C 192.168.10.0/30 is directly connected, GigabitEthernet0/1  O 10.1.1.0/24 [110/65] via 192.168.200.2, 00:01:20, Serial0/1/0  S* 0.0.0.0/0 [1/0] via 172.16.1.1  S 10.1.0.0/16 is directly connected, GigabitEthernet0/0 9. Refer to the exhibit. What is the administrative distance value of the route for router R1 to reach the destination IPv6 address of 2001:DB8:CAFE:4::A?

 120  110  1  4 10. Which value in a routing table represents trustworthiness and is used by the router to determine which route to install into the routing table when there are multiple routes toward the same destination?  administrative distance  metric  outgoing interface  routing protocol 12. Refer to the graphic. Which command would be used on router A to configure a static route to direct traffic from LAN A that is destined for LAN C?

On which two routers would a default static route be configured? (Choose two.)  any router where a backup route to dynamic routing is needed for reliability  the router that serves as the gateway of last resort  any router running an IOS prior to 12.0  stub router connection to the rest of the corporate or campus network  edge router connection to the ISP 14. Refer to the exhibit. This network has two connections to the ISP, one via router C and one via router B. The serial link between router A and router C supports EIGRP and is the primary link to the Internet. If the primary link fails, the administrator needs a floating static route that avoids recursive route lookups and any potential next-hop issues caused by the multiaccess nature of the Ethernet segment with router B. What should the administrator configure?

 Create a static route pointing to 10.1.1.1 with an AD of 95.  Create a fully specified static route pointing to Fa0/0 with an AD of 1.  Create a fully specified static route pointing to Fa0/0 with an AD of 95.  Create a static route pointing to 10.1.1.1 with an AD of 1.  Create a static route pointing to Fa0/0 with an AD of 1. 15. What is a characteristic of a floating static route?  When it is configured, it creates a gateway of last resort.  It is used to provide load balancing between static routes.  It is simply a static route with 0.0.0.0/0 as the destination IPv4 address.  It is configured with a higher administrative distance than the original dynamic routing protocol has. 16. What network prefix and prefix-length combination is used to create a default static route that will match any IPv6 destination?  FFFF::/128  ::1/64  ::/128  ::/0 17. Consider the following command: ip route 192.168.10.0 255.255.255.0 10.10.10.2 5 What does the 5 at the end of the command signify?  exit interface  maximum number of hops to the 192.168.10.0/24 network  metric  administrative distance 18. Refer to the exhibit. The routing table for R2 is as follows: Gateway of last resort is not set

60. A network administrator configures the interface fa0/0 on the router R1 with the command ip address 172.16.1.254 255.255.255.0 . However, when the administrator issues the command show ip route , the routing table does not show the directly connected network. What is the possible cause of the problem?  The subnet mask is incorrect for the IPv4 address.  No packets with a destination network of 172.16.1.0 have been sent to R1.  The configuration needs to be saved first.  The interface fa0/0 has not been activated. 61. Refer to the exhibit. Which interface will be the exit interface to forward a data packet that has the destination IP address 10.3.86.2? Gateway of last resort is not set. 10.3.86.0/26 is variously subnetted, 7 subnets, 3 masks O 10.3.86.0/26 [110/10] via 10.3.2.1, 00:00:24, Serial0/0/0 O 10.3.86.64/26 [110/20] via 10.3.2.6, 00:00:56, Serial 0/0/1 O 10.3.86.128/26 [110/10] via 10.3.2.1, 00:00:24, Serial 0/0/0 C 10.3.86.192/27 is directly connected, GigabitEthernet0/0 L 10.3.86.193/27 is directly connected, GigabitEthernet0/0 C 10.3.86.224/27 is directly connected, GigabitEthernet0/1 L 10.3.86.225/27 is directly connected, GigabitEthernet0/1 10.3.2.0/24 is variably subnetted, 4 subnets, 2 masks C 10.3.2.0/30 is directly connected, Serial0/0/0 L 10.3.2.2/32 is directly connected, Serial0/0/0 C 10.3.2.4/30 is directly connected, Serial0/0/1 L 10.3.2.5/32 is directly connected, Serial0/0/1 S 10.3.3.0/26 [1/0] via 10.3.2.1, 00:00:24, Serial0/0/0
