PCNSA Device Management and Services Practice Question
A company has two PA-220 firewalls in active/passive HA. They want to ensure that if the active firewall loses internet connectivity but its management interface remains up, a failover occurs. Which monitoring method should be configured?
⚠ Common exam trap
A common mix-up: candidates confuse 'link monitoring' (which only checks local interface status) with 'path monitoring' (which checks end-to-end connectivity to a remote target), leading them to select link monitoring when the question explicitly requires detection of internet connectivity loss beyond the first hop.
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
✓
Path monitoring.
Path monitoring is the correct method because it monitors the dataplane connectivity to specific destination IP addresses (e.g., the internet gateway) and triggers a failover when those paths become unreachable, even if the management interface remains up. This ensures that the active firewall fails over based on actual data traffic path health, not just link or management status.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Path monitoring.
Why this is correct
Correct: Path monitoring verifies reachability to a target IP and triggers failover if unreachable.
- ✗
Heartbeat backup.
Why it's wrong here
Incorrect: Heartbeat backup is for management plane redundancy, not failover triggering.
- ✗
Session replication.
Why it's wrong here
Incorrect: Session replication preserves state but does not trigger failover.
- ✗
Link monitoring on all interfaces.
Why it's wrong here
Incorrect: Link monitoring only detects physical link failure, not loss of connectivity beyond the firewall.
