Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Define class maps to match existing DSCP values
The correct order for DSCP re-marking at the WAN edge begins with configuring a trust boundary on access ports to ensure that DSCP values are trusted from trusted sources. Next, define class maps to match existing DSCP values. Then create a policy map with set dscp commands to re-mark the DSCP values. Apply the service policy to the WAN edge interface. Finally, verify the re-marking using the show policy-map interface command.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Define class maps to match existing DSCP values
Why this is correct
This step should come after configuring the trust boundary because class maps need to match the already trusted DSCP values.
- ✓
Create policy map with set dscp commands
Why this is correct
This step comes after defining class maps because the policy map uses the class maps to apply set dscp actions.
- ✓
Apply service policy to WAN edge interface
Why this is correct
This step comes after creating the policy map; the policy must be applied to the interface to take effect.
- ✓
Configure trust boundary on access ports
Why this is correct
This is the first step; trust boundary must be configured on access ports to decide which DSCP values to trust before any classification or marking.
- ✓
Verify re-marking with show policy-map interface
Why this is correct
This is the final step to verify the applied policy.
