For each option: why learners choose it and why it is or isn't the right answer here.

Disable traffic shaping
Why it's wrong here
Disabling shaping will not fix packet markings.
- ✓
Use an ACL to match the traffic and a policy-map to re-mark it
Why this is correct
This is a standard method to correct markings for endpoints that do not mark traffic correctly.
- ✗
Change the interface speed
Why it's wrong here
Interface speed does not affect marking.
