Question 4. There are intermittent connectivity issues between two internal zones on a PA-Series firewall. Although the Security policies appear correctly configured, traffic between the zones is experiencing unexpected drops. Which troubleshooting step will isolate the root cause of this behavior?
A. Use PAN-OS dataplane packet diagnostics (debug dataplane packet-diag) to filter traffic by source and destination IP addresses, capture packets at the receive, firewall, drop, and transmit stages, and analyze packet-drop counters to isolate the cause of intermittent connectivity failures
B. Use the CLI command show system info to monitor CPU and memory usage, ensuring that resource constraints are not causing interfaces to drop packets between zones.
C. Use the PAN-OS GUI Troubleshooting tool to review interface status, verify zone assignments, and confirm that all links are operational.
D. Use the CLI command show system state filter sys.sl.* | match Error to find interface errors across all the interfaces.
