Chapter 5: Ethernet

Refer to the exhibit. What is the destination MAC address of the Ethernet frame as it leaves the web server if the final destination is PC1?

00-60-2F-3A-07-CC

What is the decimal equivalent of the hexadecimal value of 3F?

63

The minimum Ethernet frame size is __________ bytes. Anything smaller than that should be considered a "runt frame."

64

The binary number 0000 1010 can be expressed as ________ in hexadecimal.

A

Which destination address is used in an ARP request frame?

FFFF.FFFF.FFFF

Refer to the graphic. H2 has sent a broadcast message to all of the hosts. If host H1 wants to reply to the broadcast message, which statement is true?

H1 sends a unicast message to H2, and the switch forwards it directs to H2.

What is a characteristic of a contention-based access method?

It is a nondeterministic method.

Which action is taken by a Layer 2 switch when it receives a Layer 2 broadcast frame?

It sends the frame to all ports except the port on which it received the frame.

The Ethernet _________ sublayer is responsible for communicating directly with the physical layer.

MAC

Refer to the exhibit. PC1 issues an ARP request because it needs to send a packet to PC3. In this scenario, what will happen next?

RT1 will send an ARP reply with its own Fa0/0 MAC address.

What type of address is 01-00-5E-0A-00-02?

an address that reaches a specific group of hosts

On Ethernet networks, the hexadecimal address FF-FF-FF-FF-FF-FF represents the _________ MAC address.

broadcast

Which term defines the processing capabilities of a switch by rating how much data can be processed per second?

forwarding rate

Which interface command must be entered in a Layer 3 switch before an IPv4 address can be assigned to that interface?

no switchport

What is the primary purpose of ARP?

resolve IPv4 addresses to MAC addresses

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

runt

A Layer 2 switch is used to switch incoming frames from a 1000BASE-T port to a port connected to a 100Base-T network. Which method of memory buffering would work best for this task?

shared memory buffering

When the store-and-forward method of switching is in use, what part of the Ethernet frame is used to perform an error check?

source MAC address in the header

When a switch configuration includes a user-defined error threshold on a per-port basis, to which switching method will the switch revert when the error threshold is reached?

store-and-forward
