48.How does quality of service help a network support a wide range of applications and services?

• by limiting the impact of a network failure

• by allowing quick recovery from network failures

• by providing mechanisms to manage congested network traffic

• by providing the ability for the network to grow to accommodate new users

9. Compared with dynamic routes, what are two advantages of using static routes on a router? (Choose two.)

• They automatically switch the path to the destination network when the topology changes

• They Improve network security

• They take less time to converge when the network topology changes

• They use fewer router resources

• They improve the efficiency of discovering neighboring networks.

50.Which connection provides a secure CLI session with encryption to a Cisco switch?

• a console connection

• an AUX connection

• a Telnet connection

• an SSH connection

51.What function does pressing the Tab key have when entering a command in IOS?

• It aborts the current command and returns to configuration mode.

• It exits configuration mode and returns to user EXEC mode.

• It moves the cursor to the beginning of the next line.

• It completes the remainder of a partially typed word in a command.

11. A network administrator adds the default-information originate command to the configuration of a router that uses RIP as the routing protocol. What will result from adding this command?

• The router will propagate a static default route in its RIP updates, if one is present

• The router will only forward packets that originate on directly connected networks.

• The router will be reset to the default factory information

• The router will not forward routing information that is learned from other routers

53.What layer is responsible for routing messages through an internetwork in the TCP/IP model?

• internet

• transport

• network access

• session

54.Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

• Data is sent from the internet layer to the network access layer.

• Packets are sent from the network access layer to the transport layer.

• Segments are sent from the transport layer to the internet layer.

• Frames are sent from the network access layer to the internet layer.

55.What unique address is embedded in an Ethernet NIC and used for communication on an Ethernet network?

• host address

• IP address

• MAC address

• network address

48. A small company has a web server in the office that is accessible from the Internet. The IP address 192.168.10.15 is assigned to the web server. The network administrator is configuring the router so that external clients can access the web server over the Internet. Which item is required in the NAT configuration?

• an IPv4 address pool

• an ACL to identify the local IPv4 address of the web server

• the ip nat inside source command to link the inside local and inside global addresses

• the keyword overload for the ip nat inside source command

13. Which route will a router use to forward an IPv4 packet after examining its routing table for the best match with the destination address?

• a level 1 child route

• a level 1 parent route

• a level 1 ultimate route

• a level 2 supernet route
