Question 3

Question 4

Question 5 (same as Q.2 of https://www.certprepare.com/port-security but answers are different)

Explanation

Port security can be enabled on both access and static trunk ports. An example of configuring port security on a static trunk port is shown below:

Switch(config)# interface fastethernet 0/1
Switch(config-if)# switchport
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport port-security

For more information about configuring port-security on trunk port please visit this link: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst4500/12-2/25sg/configuration/guide/conf/port_sec.pdf

We cannot configure port security on a dynamic interface. For example we will see an error when try it:

Switch(config)# interface fastethernet 0/1
Switch(config-if)# switchport
Switch(config-if)# switchport mode dynamic desirable
Switch(config-if)# switchport port-security
Command rejected: FastEthernet0/1 is a dynamic port.
