2.1.1 Key Elements of Ethernet/802.3 Networks
Assessment Item:
When a collision occurs in a network using CSMA/CD, how do hosts with data to transmit respond after the backoff
period has expired?
The hosts return to a listen-before-transmit mode.
The hosts creating the collision have priority to send data.
The hosts creating the collision retransmit the last 16 frames.
The hosts extend their delay period to allow for rapid transmission.

Assessment Item:
Refer to the exhibit. What action does SW1 take on a frame sent from PC_A to PC_C if the MAC address table of SW1
is empty?
SW1 drops the frame.
SW1 floods the frame on all ports on SW1, except port Fa0/1.
SW1 floods the frame on all ports on the switch, except Fa0/23 and Fa0/1.
SW1 uses the CDP protocol to synchronize the MAC tables on both switches and then forwards the frame to all ports
on SW2.

2.1.1 Key Elements of Ethernet/802.3 Networks
Assessment Item:
When a switch receives a frame and the source MAC address is not found in the switching table, what action will be
taken by the switch to process the incoming frame?
The switch will request that the sending node resend the frame.
The switch will issue an ARP request to confirm that the source exists.
The switch will map the source MAC address to the port on which it was received.
The switch ends an acknowledgement frame to the source MAC of this incoming frame.

Assessment Item:
Which two statements are true about EXEC mode passwords? (Choose two.)
The enable secret password command stores the configured password in plain text.
The enable secret password command provides better security than the enable password.
The enable password and enable secret password protect access to privileged EXEC mode.
The service password-encryption command is required to encrypt the enable secret password.
Best practices require both the enable password and enable secret password to be configured and used
simultaneously.

Assessment Item:
Which two statements are true regarding switch port security? (Choose two.)
The three configurable violation modes all log violations via SNMP.
Dynamically learned secure MAC addresses are lost when the switch reboots.
The three configurable violation modes all require user intervention to re-enable ports.
After entering the sticky parameter, only MAC addresses subsequently learned are converted to secure MAC
addresses.
If fewer than the maximum number of MAC addresses for a port are configured statically, dynamically learned
addresses are added to CAM until the maximum number is reached.
