Refer to the exhibit. The switch and workstation are administratively configured for full duplex operation. Which of the following statements accurately reflects the operation of this link?
There will be no collisions in this type of link.
Why host an Ethernet segment that experience a collision use a random delay before attempting to transmit a frame?
.
A random delay helps prevent the stations experiencing another collision during transmission.
In the graphic, Host A has completed 50% of sending an Ethernet frame from 1 KB to Host D when Host B wishes to transmit its own frame to Host C. What must Host B?
Host B must wait until you are sure that Host A has completed sending its frame.
What layers of the OSI Model Ethernet operates? (Choose two.)
- Physical Layer
- Data Link Layer
What is the standard in the IEEE 802.2 Ethernet technologies?
Sublayer Logical Link Control
Convert the binary number 10111010 into its hexadecimal equivalent. Select the correct answer from the list below.
BA
Which of the following best describes the space between frames? (Choose two.)
- The minimum interval, measured in bit times, that any station must wait before sending another frame
- The time it is provided to slow stations to process a frame and prepare for the next frame
When a collision on a network using CSMA / CD, how do hosts to respond with data to transmit after the period has expired procrastination?
The hosts return to listening mode before transmitting.
After an Ethernet collision, when invoking the algorithm delay, what device has priority to transmit data?
The device of the collision domain whose timer expires first postponement
Which of the following is a disadvantage of the access method CSMA / CD Multiple Access (carrier sense / collision detection)?
Collisions can impair network performance.
Why host an Ethernet segment that experience a collision use a random delay before attempting to transmit a frame?
A random delay helps prevent the stations experiencing another collision during transmission.
Which of the following statements correctly describe the MAC addresses? (Choose three.)
- Is copied into RAM during system startup
- Provides a 3-byte OUI
- 6 bytes long
Refer to the exhibit. The Host_A attempts to contact the Server_B. Which of the following statements correctly describe the routing generated by the Host_A in the process? (Choose two.)
- A frame with destination MAC address of Router_A.
- A packet with destination IP Server_B.
The Host A has an IP address of 172.16.225.93 and a mask of 255.255.248.0. The Host A should contact a new host whose IP is 172.16.231.78. The Host A performs the AND operation in the destination address. What are the two things that happen? (Choose two.)
- The Host A will issue an ARP request to the destination host MAC.
- It will get a result of 172.16.224.0.
What are the two characteristics that are preferred switches to hubs in Ethernet-based networks? (Choose two.)
- Reduction of collisions to a minimum
- Increase in communication performance
What model layer TCP / IP Ethernet operates?
Network Access
What are the three functions of data link sublayer in the OSI model above? (Choose three.)
identifies the network layer protocol
establishes the connection to the upper layers
protects the network layer protocols from changes in the physical equipment
What are the three main functions provided by encapsulating the data link layer? (Choose three.)
Addressing
error detection
demarcation of plots
What are the two most common types of media currently used in Ethernet networks? (Choose two.)
UTP Copper
fiber optics
Refer to the exhibit. What choice does a successful match between the type of field plot and content frame field includes?
field data - layer packet network
What is the primary purpose of ARP?
resolve the IPv4 addresses on MAC addresses
