Example Questions

What does administrative distance refer to? Which transport layer protocol provides best-effort delivery service with no acknowledgment receipt required? How does TCP differ from UDP? (Choose two) A workstation has just resolved a browser URL to the IP address of a server. What protocol will the workstation now use to determine the destination MAC address to be placed into frames directed toward the server?

How can you ensure that only the MAC address of a server is allowed by switch port Fa0/1? Which command enables IPv6 forwarding on a cisco router? What two things does a router do when it forwards a packet? (Choose two.) A switch has 48 ports and 4 VLANs. How many collision and broadcast domains exist on the switch (collision, broadcast)? Which two commands will display the current IP address and basic Layer 1 and 2 status of an interface? (Choose two) What happens when computers on a private network attempt to connect to the Internet through a Cisco router running PAT? The ip helper-address command does what? What are two common TCP applications? (Choose two.) Which two characteristics describe the access layer of the hierarchical network design model? (Choose two.) Which three statements are true about the operation of a full-duplex Ethernet network? (Choose three.) An administrator has connected devices to a switch and for security reasons, wants the dynamically learned MAC addresses from the address table added to the running configuration. What must be done to accomplish this? A receiving host has failed to receive all of the segments that it should acknowledge. What can the host do to improve the reliability of this communication session? Which two options will help to solve the problem of a network that is suffering a broadcast storm? (Choose two) The following commands are entered on the router: Burbank(config)# enable secret fortress Burbank(config)# line con 0 Burbank(config-line)# login Burbank(config-line)# password n0way1n Burbank(config-line)# exit Burbank(config)# service password-encryption What is the purpose of the last command entered? Which two commands will display the current IP address and basic Layer 1 and 2 status of an interface? (Choose two.) Why would a network administrator configure port security on a switch?
