Which feature on a Cisco router permits the forwarding of traffic for which there is no specific route?
next-hop
gateway of last resort

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.
Static routing does not advertise over the network, thus providing better security.
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.
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
to maintain routing tables
to discover the network
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
ability to actively search for new routes if the current path becomes unavailable
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.
The static route is removed from the routing table.
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.
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.
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
on a network where there is a lot of topology changes

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
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?
