Cisco CCNA Basic Switching Concepts 4

Question 1

Which frame type does a switch forward only out the single port associated with the destination MAC address?

Accepted Answer

Known unicast

Answer

When the destination MAC is found in the MAC address table (known unicast), the switch forwards the frame only to the specific port associated with that address.

Question 2

What is the collision domain boundary on a switch?

Accepted Answer

Each switch port is its own collision domain

Answer

Each port on a switch is its own collision domain because switches segment collisions at the port level.

Question 3

A Cisco switch port is configured with 'spanning-tree portfast'. What is the effect?

Accepted Answer

The port immediately transitions to Forwarding state, bypassing Listening and Learning

Answer

PortFast causes a port to skip the STP Listening and Learning states and immediately enter Forwarding, reducing connection time for end devices.

Question 4

Which type of address is FF:FF:FF:FF:FF:FF?

Accepted Answer

Broadcast MAC address

Answer

FF:FF:FF:FF:FF:FF is the Layer 2 broadcast address; frames with this destination are sent to all devices in the broadcast domain.

Question 5

What is the maximum number of MAC addresses that can be configured with port security on a single Cisco switch port by default?

Accepted Answer

1

Answer

The default maximum number of secure MAC addresses per port with port security enabled is 1.
