When a switch configuration includes a user-defined error threshold on a per-port basis, to
which switching method will the switch revert when the error threshold is reached?
cut-through
store-and-forward
fast-forward
fragment-free - ANS store-and-forward
Which two statements are correct about MAC and IP addresses during data transmission if NAT
is not involved? (Choose two.)
Destination IP addresses in a packet header remain constant along the entire path to a target
host.
Destination MAC addresses will never change in a frame that goes across seven routers.
Every time a frame is encapsulated with a new destination MAC address, a new destination IP
address is needed.
Destination and source MAC addresses have local significance and change every time a frame
goes from one LAN to another.

A packet that has crossed four routers has changed the destination IP address four times. -
ANS Destination IP addresses in a packet header remain constant along the entire path to a
target host.
Destination and source MAC addresses have local significance and change every time a frame
goes from one LAN to another.
What is one main characteristic of the data link layer?
It generates the electrical or optical signals that represent the 1 and 0 on the media.
It converts a stream of data bits into a predefined code.
It shields the upper layer protocol from being aware of the physical medium to be used in the
communication.
It accepts Layer 3 packets and decides the path by which to forward the packet to a remote
network. - ANS It shields the upper layer protocol from being aware of the physical medium
to be used in the communication.
What are three characteristics of the CSMA/CD process? (Choose three.)
The device with the electronic token is the only one that can transmit after a collision.
A device listens and waits until the media is not busy before transmitting.
After detecting a collision, hosts can attempt to resume transmission after a random time delay
has expired.
All of the devices on a segment see data that passes on the network medium.
A jam signal indicates that the collision has cleared and the media is not busy.
Devices can be configured with a higher transmission priority. - ANS A device listens and
waits until the media is not busy before transmitting.
After detecting a collision, hosts can attempt to resume transmission after a random time delay
has expired.
All of the devices on a segment see data that passes on the network medium.
What are two primary responsibilities of the Ethernet MAC sublayer? (Choose two.)
error detection
