1. Which two statements concerning networking standards are true? (Choose two.)
>provides consistent interconnections across networks
>simplifies new product development


2. Which two items are included in a network logical map? (Choose two.)
>naming scheme
>IP addressing scheme

3. What is a reason for disabling simple file sharing?
>It enables the user to set more specific security access levels.


4. Which address does an NIC use when deciding whether to accept a frame?
>destination MAC address
  
5. If the default gateway is configured incorrectly on the host, what is the impact on communications?
>The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.
  
6. 
   
Refer to the graphic. What does the router do after it determines that a data packet from Network 1 should be forwarded to Network 2?
>It reassembles the frame with different MAC addresses than the original frame.
  
7. What is the function of the FCS field in an Ethernet frame?
>detects transmission errors
  
8. Host A needs to learn the MAC address of Host B, which is on the same LAN segment. A message has been sent to all the hosts on the segment asking for the MAC address of Host B. Host B responds with its MAC address and all other hosts disregard the request. What protocol was used in this scenario?
>ARP
  
9. What is a benefit of having a router within the distribution layer?
>keeps broadcasts contained within a local network
  
10. Which term is used to describe the process of placing one message format into another format so that the message can be delivered across the appropriate medium?
>encapsulation
  
11. Which table does a router use to make decisions about the interface through which a data packet is to be sent?
>routing table
  
12. Which two networking devices are used to connect hosts to the access layer? (Choose two.)
>hub
>switch
  
13. What does the 100 mean when referencing the 100BASE-T Ethernet standard?
>speed of transmission
  
14. What device is typically used as the default gateway for a computer?
>the router interface closest to the computer
  
15. 
     
Refer to the graphic. Five PCs are connected through a hub. If host H1 wants to reply to a message from host H2, which statement is true?
>H1 sends a unicast message to H2, but the hub forwards it to all devices.


16. Which type of address is used in an Ethernet frame header?
>MAC addresses only
  
17. A switch receives a frame with a destination MAC address that is currently not in the MAC table. What action does the switch perform?
>It floods the frame out of all active ports, except the origination port.
  
18. Which device accepts a message on one port and always forwards the message to all other ports?
>hub


19. What type of route allows a router to forward packets even though its routing table contains no specific >default route
  
20. An integrated router can normally perform the functions of which two other network devices? (Choose two.)
>switch
>wireless access point


21. What is the purpose of logical addresses in an IP network?
>They are used to determine which host device accepts the frame.
