What happes to Host Profiles if the IP address of the workstation changes due to DHCP?

Lets take this scenario:

A workstation gets IP via DHCP, say 10.1.1.1.

A host profile is built for this workstation.

Now this user disconnects his workstation from the network.

Another user gets this same IP 10.1.1.1 via DHCP

What will happen to the host profile built earlier for that IP?

The new workstation might be running different OS and different set of applications

How will FMC handle this situation? Will it delete the old Host Profile and create a new one for this host? Or will it continue to update the same Host Profile? If so, won't the host profile be inaccurate due to information mixed from both hosts?

Thanks in Advance.

Not sure the whole of your network Picture.

since user get same IP address does not mean he has all the access as previous user.

depends and your polcies the user get right access thats all (in high level).

Thank you, Balaji. I am a trainer and this question came up in one of the classes. I was unsure of how host profiles will change, if another user gets the same IP due to DHCP. Will FMC delete the old profile and create new one?
