Translate Forescout to ISE language and answer 16 scenario interview questions.

## The ticket

 “Show me Live Logs.” There are none. You open Asset Inventory and the host policy tab. That is the right Forescout answer.

  Quick interview answer

 Forescout is visibility-first NAC. ISE is RADIUS-first NAC. I use Forescout to see agentless devices and ISE to authenticate users. I never scan OT blind and I never give two products the same port.

## Weak vs strong

   Weak  Strong

  NAC means 802.1X everywhere  Users 802.1X, OT passive
  Block Unknown  Notify Unknown
  Scan to be sure  Better SPAN

## Practice

 Speak Q2, Q3, Q5 in 90 seconds with 10.20.30.80 and 10.50.1.10.

## Traps

 Menus move between 8.x and 9.x. Confirm Channels / Policy Manager names on your train.
