Alta(config)# ip route 10.0.234.0 255.255.255.0 192.168.14.2
Alta(config)# ip route 0.0.0.0 0.0.0.0 s0/0/1

​7 Which two statements describe static routes? (Choose two.)

They are created in interface configuration mode.
They require manual reconfiguration to accommodate network changes.*
They automatically become the default gateway of the router.
They are identified in the routing table with the prefix S.*
They are automatically updated whenever an interface is reconfigured or shutdown.

8 Fill in the blank.
A “floating” static route can be used to provide a backup route to a dynamically learned route.

9 Which two conditions must exist in order to summarize IPv6 routes into a single static IPv6 route? (Choose two.)

The destination networks are contiguous and can be summarized into a single network address.*
The multiple static routes all use different exit-interface or next-hop IPv6 address.
The destination networks are not contiguous.
The multiple static routes all use the same exit-interface or next-hop IPv6 address.*
The administrative distance is greater than the administrative distance of another static route or dynamic routes.

10 Which is a valid summary route for networks 192.168.8.0/22, 192.168.12.0/22, and 192.168.16.0/22?

192.168.0.0/18
192.168.0.0/19*
192.168.0.0/20
192.168.8.0/21

11 Open the PT Activity. Perform the tasks in the activity instructions and then answer the question or complete the task.

Why are the pings from PC0 to Server0 not successful?

The static route to network 192.168.1.0 is misconfigured on Router1.
The static route to network 192.168.1.0 is misconfigured on Router2.
The static route to network 192.168.2.0 is misconfigured on Router1.*
The static route to network 192.168.2.0 is misconfigured on Router2.

12 What command, or set of commands, would be used to determine if the following configuration on router HQ works as designed?

ip route 0.0.0.0 0.0.0.0 serial 0/0/0 10
ip route 0.0.0.0 0.0.0.0 serial 0/1/0

HQ(config)# interface serial 0/1/0
HQ(config-if)# shutdown
HQ(config-if)# end
HQ# show ip route*

HQ# traceroute 128.107.0.99

HQ# show ip interface brief

HQ# ping 128.107.0.99
HQ# ping 64.100.0.5

HQ# show ip route

13 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*

14 Why would a summarized static route be configured on a router?

to reduce the number of public IP addresses required by an organization
to provide a better route than a particular routing protocol
to provide a default gateway for a router that connects to an ISP
to reduce the size of the routing table*
to reduce the size of the routing protocol update to a neighboring router

15 Which subnet mask would be used for a network that has a maximum of 300 devices?

255.255.255.0
255.255.254.0*
255.255.252.0
255.255.248.0
255.255.240.0
