1. 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?
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?
flow control2.
encapsulation
encoding
multicasting
access method
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.3. Which two statements concerning networking standards are true? (Choose two.)
H1 sends a unicast message to H2, and the hub forwards it directly to H2.
H1 sends a broadcast message to H2, and the hub forwards it to all devices.
H1 sends a multicast message to H2, and the hub forwards it directly to H2.
adds complexity to networks4. What does the 100 mean when referencing the 100BASE-T Ethernet standard?
encourages vendors to create proprietary protocols
provides consistent interconnections across networks
ensures that communications work best in a single-vendor environment
simplifies new product development
type of cable used5. Which address does an NIC use when deciding whether to accept a frame?
type of data transmission
speed of transmission
type of connector required
maximum length of cable allowed
source IP address6. Which type of address is used in an Ethernet frame header?
source MAC address
destination IP address
destination MAC address
source Ethernet address
logical addresses only7. What is the function of the FCS field in an Ethernet frame?
IP addresses only
MAC addresses only
broadcast addresses only
detects transmission errors8. What is the purpose of logical addresses in an IP network?
provides timing for transmission
contains the start of frame delimiter
indicates which protocol will receive the frame
They identify a specific NIC on a host device.9. Which device accepts a message on one port and always forwards the message to all other ports?
They are used to determine which host device accepts the frame.
They provide vendor-specific information about the host.
They are used to determine the network that the host is located on.
They are used by switches to make forwarding decisions.
modem10. Which two networking devices are used to connect hosts to the access layer? (Choose two.)
switch
router
hub
router11. 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?
hub
switch
server
computer
ARP12. A switch receives a frame with a destination MAC address that is currently not in the MAC table. What action does the switch perform?
DHCP
DNS
WINS
It drops the frame.13. What is a benefit of having a router within the distribution layer?
It sends out an ARP request looking for the MAC address.
It floods the frame out of all active ports, except the origination port.
It returns the frame to the sender.
prevents collisions on a local network14.
keeps broadcasts contained within a local network
controls which hosts have access to the network
controls host-to-host traffic within a single local network
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 sends the data packet as it was received.15. Which table does a router use to make decisions about the interface through which a data packet is to be sent?
It reassembles the frame with different MAC addresses than the original frame.
It reassembles the data packet with different IP addresses than the original data packet.
It reassembles both the packet and the frame with different destination IP and MAC addresses.
ARP table16. If the default gateway is configured incorrectly on the host, what is the impact on communications?
routing table
network table
forwarding table
The host is unable to communicate on the local network.17. What device is typically used as the default gateway for a computer?
The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks.
The host can communicate with other hosts on remote networks, but is unable to communicate with hosts on the local network.
There is no impact on communications.
a server hosted by the ISP18. What type of route allows a router to forward packets even though its routing table contains no specific route to the destination network?
the router interface closest to the computer
a server managed by a central IT department
the switch interface that connects to the computer
dynamic route19. Which two items are included in a network logical map? (Choose two.)
default route
destination route
generic route
naming scheme20. An integrated router can normally perform the functions of which two other network devices? (Choose two.)
IP addressing scheme
length of cable runs
physical location of networking devices
specific layout of interconnections between networking devices and hosts
NIC21. What is a reason for disabling simple file sharing?
switch
e-mail server
application server
wireless access point
It enables the user to map a remote resource with a local drive.
It enables the user to share all files with all users and groups.
It enables the user to share printers.
It enables the user to set more specific security access levels.
