As you can see above, how do we know Fastethernet 0/5 has statically assigned MAC address?

Hi,
It seems that there is no address static from the command of "show mac-address-table".
If it is original, "Static Address (User-defined) Count:" will increase.

Thanks for the reply.
According to this question:
A. A hub is connected directly to FastEthernet 0/5
B. FastEthernet0/1 is connected to a host with multiple network interface cards.
C. Interface FastEthernet 0/2 has been disabled.
D. Multiple devices are connected directly to FastEthernet0/1.
E. FastEthernet0/1 is configured as a trunk link.
F: Fast Ethernet0/5 has statically assigned MAC addresses.
My answer: A E.
Correct answer is E F
Do you think the answer suggested is wrong?

"0010.7b00" -- since this is the MAC Address of Cisco, it is considered to be also Static.
Therefore, aren't E and F considered, either?

Is this a fact that ""0010.7b00" is a static MAC address of Cisco?
Are there are any other static MAC address for Cisco routers or switch?
