MOD 14-16

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.)

• • Configuration of static routes is error-free.

• Static routing does not advertise over the network, thus providing better security.

• No intervention is required to maintain changing route information.

• The path a static route uses to send data is known.

• Static routing typically uses less network bandwidth and fewer CPU. operations than dynamic routing does.

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 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
