Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A class-map can match multiple criteria using 'match-all' or 'match-any'.
Why this is correct
match-all requires all criteria; match-any requires any.
- ✗
A policy-map can be applied globally to all interfaces.
Why it's wrong here
Policy-maps are applied per interface or subinterface.
- ✓
A policy-map can contain a 'class class-default' for unclassified traffic.
Why this is correct
class-default handles traffic not matching other classes.
- ✗
The 'service-policy' command is used in global configuration mode.
Why it's wrong here
It is applied under interface configuration.
- ✗
WRED can only be configured within a policy-map class.
Why it's wrong here
