Explanation / Answer

Answer:

8) port 20 & 21 : port 20 is used for data and 21 is used for control plane.

9)True : we dont see any source in packet capture.

10) you have to craete cisco type 5 password which is encrypted and can not be viewed in config file.

11) Answer is sticky secure mac address:

Static secure MAC address:Static secure MAC addresses—These are manually configured by using the switchport port-security.

Sticky secure MAC addresses—These can be dynamically learned or manually configured, stored in the address table, and added to the running configuration. If these addresses are saved in the configuration file, the interface does not need to dynamically relearn them when the switch restarts. Although sticky secure addresses can be manually configured, we do not recommend it.
