FDB table for 500 entries, will there be flooding, forwarding or filtering when 600 subscribers are connected?

Question

System administration

On a certain switch, the size of the FDB table is 500 entries. If you connect 600 clients to it in one broadcast domain, then with all clients enabled, when transmitting data on the network ...
- only flooding
will occur - flooding and forwarding
will occur - flooding, forwarding and filtering will occur

Answer 1

You propose to guess the behavior of an unknown switch in an abstract situation:

• you will drop out of the university without passing the exam
  
• you will not pass the offsite interview
  
• you will drop out of the university and fail the interview.
  

Answer 2

flooding

Yes, when sending a frame with a destination MAC address that does not fit in the FDB (there are about 100 of them in total), the frame will be copied to all ports (except the one it originally came to).

forwarding

Yes, when a frame is sent with the destination MAC address in the FDB, the frame will only be forwarded to the appropriate port.

filtering

Not sure what exactly is meant by this term. If there is some kind of ACL filtering, then it has nowhere to appear in this context. On the other hand, the switch is sometimes called a filtering bridge (FDB, by the way, is a filtering database), but in this sense I see no reason for filtering (i.e. no special filtering entry in the FDB, nor receiving a frame with a MAC address destination A to the port with which this address is associated).
In any case, you'd better consult the study materials.
