Answer choices
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

The source NAT rule must explicitly match the source zone and destination zone of the traffic, along with the source interface if specified.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable 'Address Translation' in the NAT rule.
Why it's wrong here
This would prevent the translation from occurring.
- ✗
Enable 'Proxy ARP' on the egress interface.
Why it's wrong here
Proxy ARP is for resolving IP addresses, not for NAT matching.
- ✓
Select the specific source zone and destination zone in the NAT rule.
Why this is correct
NAT rules are zone-based; you must specify the source and destination zones for the rule to trigger.
- ✗
Configure a policy-based forwarding rule instead of NAT.
Why it's wrong here
PBF controls path selection, not IP address translation.
