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

0A

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

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

Broadcast

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

CRC in the trailer

Which two functions or operations are performed by the MAC sublayer? (Choose two.)

It adds a header and trailer to form an OSI Layer 2 PDU. It is responsible for Media Access Control.

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

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

an address that reaches a specific group of hosts

What is the primary purpose of ARP?

resolve IPv4 addresses to MAC addresses

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 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
