Refer to the exhibit. If host A sends an IP packet to host B, what will the
destination address be in the frame when it leaves host A?
DD:DD:DD:DD:DD:DD
172.168.10.99

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?
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. - CORRECT ANSWER : 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. - CORRECT ANSWER : 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.
