SLA Class - strict - AAR

I have a question.

If configuring an AAR policy, and you set the SLA Class to strict with a preferred colour, does that render the SLA class performance moot, as even if the SLA is breached, it will still only use the "strict" colour?

Thanks!

If the Preferred route not available, then if other SLA matches it uses that path - again it all depends how this was configured on the policy - better look below example : (for understanding)
