A firewall is experiencing high dataplane CPU usage. You suspect a specific traffic pattern is causing the issue. Which two steps should you take to confirm the cause?

Disable the dataplane and use management plane for all traffic processing.

Review the session table for high session counts and use packet capture to analyze traffic patterns.

Increase the dataplane CPU allocation to handle the load without investigating the cause.

Check the system log for error messages and reboot the firewall to clear the high CPU usage.
