This is a CCNA lan chapter 9 review quiz. It is designed for all of you who are preparing to take the exam but are having a hard time when it comes to reviewing all you know about the local area network. If that is, you just press the start button and begin your journey in understanding the chapter a little better.
The device involved in the collision with the lowest MAC address
The device involved in the collision with the lowest IP address
Any device in the collision domain whose backoff timer expires first
Those that began transmitting at the same time
Network layer
Transport layer
Physical layer
Application layer
Data-link layer
The minimum interval, measured in bit-times, that any station must wait before sending another frame.
The maximum interval, measured in bit-times, that any station must wait before sending another frame.
the 96-bit payload padding inserted into a frame to achieve a legal frame size
The 96-bit frame padding transmitted between frames to achieve proper synchronization
The time allowed for slow stations to process a frame and prepare for the next frame.
Addressing
Error detection
Frame delimiting
Port identification
Path determination
The hosts return to a listen-before-transmit mode.
The hosts creating the collision have priority to send data.
The hosts creating the collision retransmit the last 16 frames.
The hosts extend their delay period to allow for rapid transmission.
Recognizes streams of bits
Identifies the network layer protocol.
makes the connection with the upper layers.
Identifies the source and destination applications
Insulates network layer protocols from changes in physical equipment.
MAC sublayer
Physical layer
Logical Link Control sublayer
Network layer
A random delay is used to ensure a collision-free link.
A random delay value for each device is assigned by the manufacturer.
A standard delay value could not be agreed upon among networking device vendors.
A random delay helps prevent the stations from experiencing another collision during the transmission.
Header field - preamble and stop frame
Data field - network layer packet
Data field - physical addressing
Trailer field - FCS and SoF
Host A will change the destination IP to the IP of the nearest router and forward the packet.
Host A will broadcast an ARP request for the MAC of its default gateway.
A result of 172.16.225.0 will be obtained
Host A will broadcast an ARP request for the MAC of the destination host.
A result of 172.16.225.255 will be obtained.
Collisions can decrease network performance.
It is more complex than non-deterministic protocols.
Deterministic media access protocols slow network performance.
CSMA/CD LAN technologies are only available at slower speeds than other LAN technologies.
