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 route to the destination network?
#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.
