CCNA 2 Chapter 4 Exam Answer 003 (v5.02, 2015)

  • Drop the packet.
  • Send the packet out the Serial0/0/0 interface.
  • Send the packet out the GigabitEthernet0/0 interface.
  • Send the packet out the GigabitEthernet0/1 interface.

14. Which two statements correctly describe the concepts of administrative distance and metric? (Choose two.)

  • Administrative distance refers to the trustworthiness of a particular route.
  • A router first installs routes with higher administrative distances.
  • The value of the administrative distance can not be altered by the network administrator.
  • Routes with the smallest metric to a destination indicate the best path.
  • The metric is always determined based on hop count.
  • The metric varies depending which Layer 3 protocol is being routed, such as IP.

15. Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. Which two types of routes are displayed in the routing table? (Choose two.)

CCNA 2 Chapter 4 Exam Answer 004 (v5.02, 2015)

CCNA 2 Chapter 4 Exam Answer 004 (v5.02, 2015)

  • static route
  • local host route
  • directly connected network
  • route that is learned through the OSPF routing protocol
  • route that is learned through the EIGRP routing protocol

16. Refer to the exhibit. A network administrator issues the show ipv6 route command on R1. What two conclusions can be drawn from the routing table? (Choose two.)

CCNA 2 Chapter 4 Exam Answer 005 (v5.02, 2015)

CCNA 2 Chapter 4 Exam Answer 005 (v5.02, 2015)

  • static route
  • local host route
  • directly connected network
  • route that is learned through the OSPF routing protocol
  • route that is learned through the EIGRP routing protocol

17. 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?

  • The interface fa0/0 has not been activated.
  • The configuration needs to be saved first.
  • No packets with a destination network of 172.16.1.0 have been sent to R1.
  • The subnet mask is incorrect for the IPv4 address.

18. 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 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 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

19. A network administrator is implementing dynamic routing protocols for a company. Which command can the administrator issue on a router to display the supported routing protocols?

  • Router(config)# router ?
  • Router(config)# service ?

CCNA 2 Chapter 4 Exam Answer 007 (v5.02, 2015)

  • It indicates that this is a default route.
  • It indicates that this route was learned via EIGRP.
  • It indicates that this is a directly connected route.
  • It indicates that this route has been deleted from the routing table.

22. Which statement describes a route that has been learned dynamically?

  • It is automatically updated and maintained by routing protocols.
  • It is unaffected by changes in the topology of the network.
  • It has an administrative distance of 1.
  • It is identified by the prefix C in the routing table.

23. Fill in the blank.

When a router receives a packet, it examines the destination address of the packet and looks in the              Routing                 table to determine the best path to use to forward the packet.

24. Refer to the exhibit. Match the description with the routing table entries. (Not all options are used.)
