Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
All policies, both global and zone-based, are evaluated in a single combined sequence based strictly on rule naming alphabetically.
Why it's wrong here
Incorrect. Evaluation order is determined by policy type (zone-based then global), not alphabetical naming.
- ✗
Policies are evaluated based on IP prefix length regardless of whether they are global or zone-based.
Why it's wrong here
Incorrect. Prefix length does not dictate policy evaluation order in Junos.
- ✗
Global policies are evaluated first, followed by zone-based policies.
Why it's wrong here
Incorrect. Global policies are evaluated after zone-based policies.
- ✓
Zone-based policies are evaluated first, followed by global policies.
Why this is correct
Correct. Junos evaluates zone-based policies before falling back to global policies.
