  • open the header and use it to determine whether the data is to be sent out S0/0/0
  • open the header and replace the destination MAC address with a new one
  • nothing, because the router has a route to the destination network

Image (binary/octet-stream)
Answer
  • The network FF00::/8 is installed through a static route command.
  • Packets that are destined for the network 2001:DB8:ACAD:2::54/128 will be forwarded through Fa0/0.
  • Packets that are destined for the network 2001:DB8:ACAD:2::/64 will be forwarded through Fa0/1.

  • R1 does not know a route to any remote networks.

Question 20

Question
A network administrator configures the interface fa0/0 on the router R1 with the command ip address 172.16.1.254 255.255.255.0. However, when the administrator issues the command show ip route, the routing table does not show the directly connected network. What is the possible cause of the problem?
Answer
  • The subnet mask is incorrect for the IPv4 address.
  • No packets with a destination network of 172.16.1.0 have been sent to R1.
  • The configuration needs to be saved first.
  • The interface fa0/0 has not been activated.

  • to forward packets destined for the network 0.0.0.0 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 forward all packets to the device with IP address 209.165.200.226

Question 22

Question

Question 27

Question
What is a characteristic of a static route that matches all packets?
Answer
  • 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.
  • It uses a single network address to send multiple static routes to one destination address.

Question 29

Question
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 act as a gateway of last resort
  • to load-balance the traffic
  • to be used as a backup route
