Which IPv4 static route statement is true? The destination network is identified using the network address and wildcard mask. The distance keyword is used to create a fully specified static route. The source network is identified using the network address and wildcard mask. Using the exit interface only is common in a point-to-point configuration.

Using the exit interface only is common in a point-to-point configuration.

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 10ip route 0.0.0.0 0.0.0.0 serial 0/1/0 -HQ# ping 128.107.0.99 HQ# ping 64.100.0.5 -HQ# traceroute 128.107.0.99 -HQ# show ip interface brief -HQ(config)# interface serial 0/1/0 HQ(config-if)# shutdown HQ(config-if)# end HQ# show ip route -HQ# show ip route

-HQ(config)# interface serial 0/1/0 HQ(config-if)# shutdown HQ(config-if)# end HQ# show ip route To test a floating static route, take down the main route/link in order to see whether the backup link appears in the routing table.

What is the purpose of a floating static route? -It allows connectivity to remote destinations that are not contained in the routing table. -It is commonly used when a dynamic routing protocol is not being used. -It allows an alternate connection to be used when the preferred link fails. -It allows summarization of contiguous networks.

-It allows an alternate connection to be used when the preferred link fails.

What is a characteristic of a default static route? ​ -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 is the original dynamic routing protocol. -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.

Which IPv6 static route would serve as a backup route to a dynamic route learned through OSPF? -Router1(config)# ipv6 route 2001:db8:acad:1::/32 2001:db8:acad:6::2 200 -Router1(config)# ipv6 route 2001:db8:acad:1::/32 gigabitethernet0/0 2001:db8:acad:6::100 100 -Router1(config)# ipv6 route 2001:db8:acad:1::/32 2001:db8:acad:6::100 -Router1(config)# ipv6 route 2001:db8:acad:1::/32 2001:db8:acad:6::2 100

-Router1(config)# ipv6 route 2001:db8:acad:1::/32 2001:db8:acad:6::2 200 The command ipv6 route 2001:db8:acad:1::/32 2001:db8:acad:6::2 200, specifies a floating static route to the 2001:db8:acad:1::/32 network with an administrative distance of 200. Since OSPF has an administrative distance of 110, the static route would only be placed in the routing table if the OSPF learned route was removed.

A network administrator uses the command ip route 172.18.0.0 255.255.0.0 S0/0/1 to configure a floating static route on a router. That route will function as a backup route to reach the EIGRP learned network 172.18.0.0/16. After this configuration, the EIGRP route is removed from the routing table even though EIGRP is still functioning properly. Why is the static route not functioning as intended? -The administrative distance value is not high enough on the static route. -The next hop neighbor IP address is not configured. -The network mask is incorrectly configured. -The destination network is incorrectly configured.

-The administrative distance value is not high enough on the static route.

A network administrator is configuring a route to forward packets to a specific web server. What type of route should be configured by the administrator? -a host route -a default route -a static route with an administrative distance higher than 1 -an OSPF route -an EIGRP route

-a host route A host route is a route installed in the routing table where the destination address has a subnet mask of /32 for IPv4 or /128 for IPv6, an address of a specific device. A host route can allow for a more efficient processing of packets that are directed to the device, rather than for packet forwarding, such as by a default route, an OSPF route, or an EIGRP route.

Which type of static route that is configured on a router uses only the exit interface? -recursive static route -directly connected static route -default static route -fully specified static route

-directly connected static route

What type of static route is created when the next-hop IP address and exit interface are specified? -directly connected static route -fully specified static route -recursive static route -floating static route

-fully specified static route

A network administrator configures a router by the command ip route 0.0.0.0 0.0.0.0 209.165.200.226. What is the purpose of this command? -to forward packets destined for the network 0.0.0.0 to the device with IP address 209.165.200.226 -to provide a route to forward packets for which there is no route in the routing table -to forward all packets to the device with IP address 209.165.200.226 -to add a dynamic route for the destination network 0.0.0.0 to the routing table

-to provide a route to forward packets for which there is no route in the routing table

What network address and subnet mask combination would be used to create a default static route that matches any IPv4 destination? 255.255.255.255 0.0.0.0 0.0.0.0 255.255.255.255 0.0.0.0 0.0.0.0 255.255.255.255 255.255.255.255

0.0.0.0 0.0.0.0

Which type of static route typically uses the distance parameter in the ip route global configuration command? summary static route standard static route floating static route default static route

floating static route

What is the correct syntax of a floating static route? ip route 172.16.0.0 255.248.0.0 10.0.0.1 ip route 0.0.0.0 0.0.0.0 serial 0/0/0 ip route 209.165.200.228 255.255.255.248 10.0.0.1 120 ip route 209.165.200.228 255.255.255.248 serial 0/0/0

ip route 209.165.200.228 255.255.255.248 10.0.0.1 120

Which static route statement shows a recursive IPv6 static route? ipv6 route 0::/0 S0/0/0 ipv6 route 2001:db8:cafe:1::/56 S0/0/0 2001:db8:1000:10::1 ipv6 route 2001:db8:cafe:1::/56 S0/0/0 ipv6 route 0::/0 S0/0/0 254 ipv6 route 2001:db8:cafe:1::/56 2001:db8:1000:10::1

ipv6 route 2001:db8:cafe:1::/56 S0/0/0 2001:db8:1000:10::1

Which command would create a valid IPv6 default route? ipv6 route ::/128 2001:db8:acad:1::1 ipv6 route ::/0 2001:db8:acad:2::a ipv6 route ::/0 fe80::1 ipv6 route 2001:db8:acad:1::/64 ::1

ipv6 route ::/128 2001:db8:acad:1::1 The correct prefix and prefix length for a default route is ::/0, which matches any address. ::/128 matches only the specific address of all zeros. When creating a static route that uses a link-local address as the next hop, an exit interface must also be specified for the route to be valid.

Which two methods can be used to identify the next hop in a static route? (Choose two.) destination interface next hop IP address destination network address exit interface source IP address

next hop IP address exit interface

Why would a floating static route be configured with an administrative distance that is higher than the administrative distance of a dynamic routing protocol that is running on the same router? to be the priority route in the routing table to act as a gateway of last resort to be used as a backup route to load-balance the traffic

to be used as a backup route

How is the destination network in an IPv6 static route identified? using an IPv6 prefix and prefix length using an IPv6 prefix and subnet mask using an IPv6 prefix and wildcard mask using an IPv6 prefix only

using an IPv6 prefix and prefix length
