Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Verify that the source NAT rule is active and correctly applied to the traffic zone
Why this is correct
Correct. NAT rule matching is the first requirement for successful translation.
- ✓
Ensure security policies permit traffic from the source zone to the destination zone
Why this is correct
Correct. Security policies evaluate traffic before NAT processing occurs.
- ✗
Check IKE Phase 1 authentication keys
Why it's wrong here
IKE keys relate to IPsec VPNs, not source NAT.
- ✓
Check source NAT pool utilization to ensure addresses are not exhausted
Why this is correct
Correct. Pool exhaustion prevents new NAT allocations.
- ✗
Verify that static routing table metrics are set to preferred values
Why it's wrong here
NAT does not rely on routing metric values for translation mapping.
