Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
When evaluating a security policy, Junos checks zone-specific address books associated with the source zone before checking the global address book.
Why this is correct
Local zone address books have precedence for matching traffic from that zone.
- ✗
Address book evaluation order requires manual priority numbering in the CLI.
Why it's wrong here
Evaluation order is determined automatically by Junos based on scope (zone vs global).
- ✗
Zone-specific address books can only contain IPv4 addresses, while global address books contain IPv6 addresses.
Why it's wrong here
Both address book types support IPv4 and IPv6.
- ✗
Global address books always override zone-specific address books regardless of traffic direction.
Why it's wrong here
Zone-specific address books override global entries for their respective zones.
- ✓
If an address name is defined uniquely in the global address book, it is available to all security zones.
Why this is correct
Global address books provide universal availability across all zones.
