There is no matching interface associated with network 172.16.0.0 so packets will be dropped.
There is no matching interface associated with network 172.16.0.0 so packets will take gateway of last resort and exit out S0/2.

Refer to the exhibit. What is the significance of the /8 in the route to the 10.0.0.0 network?

A network administrator enters the following command into Router1: ip route 192.168.0.0 255.255.255.0 S0/1/0. Router1 then receives a packet that is destined for 192.168.0.22/24. After finding the recently configured static route in the routing table, what does Router1 do next to process the packet?

drops the packet because the destination host is not listed in the routing table
looks up the MAC address of the S0/1/0 interface to determine the destination MAC address of the new frame
performs a recursive lookup for the IP address of the S0/1/0 interface before forwarding the packet
encapsulates the packet into a frame for the WAN link and forwards the packet out the S0/1/0 interface

A router has one static route to each destination network. Which two scenarios would require an administrator to alter the static routes that are configured on that router? (Choose two.)

The destination network no longer exists.
The destination network is moved to a different interface on the same router.
The path between the source and destination is upgraded with a higher bandwidth link.
A topology change occurs where the existing next-hop address or exit interface is not accessible.
The remote destination network interface has to be down for 15 minutes of maintenance.

Which of the following is true regarding CDP and the graphic shown?

CDP running on Router D will gather information about routers A, B, C, and E.
By default, Router A will receive CDP advertisements from routers B and C.
If routers D and E are running different routing protocols, they will not exchange CDP information.
Router E can use CDP to identify the IOS running on Router B.

Why is it advisable to enter a next-hop IP address when creating a static route whose exit interface is an Ethernet network?

Adding the next-hop address eliminates the need for the router to do any lookups in the routing table before forwarding a packet.
In a multi-access network, the router cannot determine the next-hop MAC address for the Ethernet frame without a next-hop address.
Using a next-hop address in a static route provides a route with a lower metric.
In multi-access networks, using a next-hop address in a static route makes that route a candidate default route.
