It monitors the media for presence of a data signal.
After detecting a collision, hosts can resume transmission after a random timer has expired.
A jam signal is used to ensure that all hosts are aware that a collision has occurred.
Devices can be configured with a higher transmission priority.
Data is transmitted only when the data signal is present.

The gateway addresses are broadcast addresses.
Host Y is assigned a multicast address.
Host X and host Y belong to different networks.
Host X is assigned a network address.
The interface is configured as a DCE device.

TCP and UDP manage communication between multiple applications.
TCP retransmits the packets for which the acknowledgment is not received.
UDP exchanges frames between the nodes of the network.
UDP exchanges frames between the nodes of the network.
UDP uses windowing and sequencing to provide reliable transfer of data.

• ring
• point-to-point
• multi-access
It affects the operation of the device immediately when modified.
It is stored in NVRAM.
It should be deleted using the erase running-config command.
It is automatically saved when the router reboots.
Hosts A and B are not on the same subnet as host C.
The IP addresses on the router serial interfaces are wrong.
The subnet mask on host C is improperly configured.
The FastEthernet interface fa0/0 of router 1 is wrongly configured.
It uses error control mechanisms.
It uses a connectionless protocol only for multiple simultaneous transmissions.
It uses multiple Layer 2 source addresses.

Configure the description at interface serial 0/0/0.
Configure an IP address on interface serial 0/0/0.
Remove the no shutdown command at interface serial 0/0/0
Reboot the router.
The initial window size is determined via the two-way handshake.
The window size for the TCP session that is represented is initially set to 3000 bytes.
Acknowledgment number 3001 indicates that host A will send the next segment with sequence number 3001.
Host B expects that the next received segment number will be 3000.
No more acknowledgments will be exchanged.

It segments and reorders the data.
It exchanges data between programs that are running on the source and destination hosts.
It controls how data is placed onto the media.
It generates signals to represent the bits in each frame.
It encapsulates each packet with a header and a trailer to transfer it across the local media

The table will remain unaffected.
The switch will remove the MAC address at Fa0/19 immediately.
The switch will retain the MAC address until host B is powered on again.
The switch will rebuild the MAC table by assigning the FFFF.FFFF.FFFF address to port Fa0/19.
The cable that is used is an Ethernet crossover cable.
The transmit pin of the cable is terminated to the receive pin.
The maximum distance between the switch and the PC can be 100 m.
The maximum supported bandwidth is 1000 Mb/s.
The Category 6 cable simulates a point-to-point WAN link and is unusable for this type of connection.
