Ethernet Flashcards Chapter 5

Which destination address is used in an ARP request frame?

Is this a characteristic of cut-through or store-and-forward? Always stores the entire frame.

Is this a characteristic of cut-through or store-and-forward? Checks the CRC before forwarding.

Is this a characteristic of cut-through or store-and-forward? Checks the frame length before forwarding.

Is this a characteristic of cut-through or store-and-forward? Does not forward broadcasts.

Is this a characteristic of cut-through or store-and-forward? Has low latency.

Is this a characteristic of cut-through or store-and-forward? May forward runt frames.

Is this a characteristic of cut-through or store-and-forward? Begins forwarding when the destination address is received.

The ARP table in a switch maps which two types of addresses together?

Which two statements describe features or functions of the logical link control sublayer in Ethernet standards? (Choose two.)

ARP ____________ is a technique that is used to send fake ARP messages to other hosts in the LAN.

What happens to runt frames received by a Cisco Ethernet switch?

What are the two sizes (minimum and maximum) of an Ethernet frame? (Choose two.)

What is auto-MDIX?

On a Cisco switch, _____________ memory buffering is used to buffer frames in queues linked to specific incoming and outgoing ports.

Which statement describes the treatment of ARP requests on the local link?

What statement describes a characteristic of MAC addresses?

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.

What are two potential network problems that can result from ARP operation? (Choose two.)

A collision fragment, also known as a _______ frame, is a frame of fewer than 64 bytes in length.

Which statement is true about MAC addresses?

What addressing information is recorded by a switch to build its MAC address table?

What statement describes Ethernet?

Which switching method uses the CRC value in a frame?

When a network device wants to communicate with another device on the same network, it sends a ____________ _____ _________.

The destination device of a broadcast ARP request containing the IP in the request, sends an ________ ______ with its MAC address.

Ethernet operates in which layer or layers?

The Ethernet protocol standards define many aspects of network communication including frame format, frame size, timing, and encoding.

The OSI model separates the data link layer functionalities of addressing, framing, and accessing the media from the physical layer standards.

Ethernet is a family of networking technologies that are defined in the IEEE 802.2 and 802.3 standards.

The Ethernet LLC sublayer handles the communication between?

LLC is implemented in __________ , and its implementation is independent of the __________.

MAC constitutes the lower sublayer of the data link layer.

Frame delimiting, addressing, and error detection are all examples of?

Control of frame placement on and off the media and media recovery are both examples of?

The Ethernet MAC sublayer has two primary responsibilities; what are they?

The data encapsulation process includes frame assembly ___________ transmission over the media.

Frame dis-assembly happens at the host or source?

The framing process provides important delimiters that are used to identify a group of bits that make up a frame. This is known as what term in data encapsulation?

The encapsulation process contains the Layer 3 PDU and also provides for data link layer addressing. This is known as what term in data encapsulation?

Each frame contains a trailer used to detect any errors in transmissions. This is known as what term in data encapsulation?

What data link sublayer is responsible for the placement of frames on the media and the removal of frames from the media?

A contention-based method means what?

The latest versions of Ethernet operate at what speed?

The preamble (7 bytes) and start frame delimiter (SFD), also called the start of frame (1 byte), fields are used for synchronization between the sending and receiving devices.

The minimum Ethernet frame size is 64 bytes and the maximum is 1518 bytes. This includes all bytes from the destination MAC address field through the frame check sequence (FCS) field.

Any frame less than 64 bytes in length is considered a collision fragment or runt frame and is automatically discarded by receiving stations.

Ethernet frame field, what is it?
