Moduke 3 Flashcards
(24 cards)
True or False
The LLC sublayer communicates with the transport layer
False
T/F
Audio MDIX is a feature that detects Ethernet cable types
True
LLC(logic link control sublayer) protocol is transmission media dependent
False
T/F
When a device is sending data to another device on a remote network, the Ethernet frame is sent to the MAC address of the default gateway.
True
A managed switch can only be configured via a console which is physically connected to the console port of the switch
False
Modern Ethernet networks is based on the bus tolopoly
False
What is a correct description of the switching method
Store and forward: ensures that’s the frame is free of physical and data link errors
What will a host on an Ethernet network do if it receives a frame with a unicast destination MAC address that does not match its own MAC address?
Discard the frame
What is the portion on the network where collisions occur when 2 nodes transmit data at the same time
A collision domain
What is the purpose of the preamble on am Ethernet frame
Time synchronization
MAC addresses have
A vendor assigned oui in the first 3 bytes
Within the Ethernet II frame, what signals the receiving node that data is incoming and indicates when data flow starts
The SFD
What addressing info is recorded by a switch to build its MAC address table?
the source Layer 2 address of incoming frames
By default, what is the MTU on a network
1500 bytes
What IEEE standard is used for Ethernet
802.3
Whhat statements describe features or functions of the logical link control sublayer in Ethernet standards?
Logical link control is implemented in software.
The data link layer uses LLC to communicate with the upper layers of the protocol suite.
What name does the data link layer use for its PDU
Frame
What describes the chars of a MAC address
They must be globally unique
What happens to the frames received by a switch if the frames are less than 64 bytes or greater than 1518 bytes?
It’ll be dropped
What network device can serve as a boundary to divide a layer 2 broadcast domain?
A router
What is not used to find nodes on networks other than the
local network.
A broadcast MAC address
Store and forward method
- checks the frames length before proceeding
- checks the crc before moving forward
- always stores the entire frame
Cut through
- begins forwarding once the destination address is received
- might forward runts
- has a low latency
