A firewall is experiencing high CPU usage, and the administrator suspects a specific security policy is causing excessive logging. The administrator wants to confirm the cause before making changes. Which systematic approach should the administrator use?

Check the system log for 'high CPU' alerts and ignore the traffic log

Immediately disable the suspected policy and monitor CPU usage

Review the traffic log for the affected policy, then use the 'show session info' command to check session counts

Reboot the firewall to clear the high CPU usage

A firewall in a branch office is intermittently dropping traffic on a specific interface. The administrator checks the system log and finds repeated 'ipsec negotiation failed' messages, but the phase 1 and phase 2 settings appear correct when compared to the head office configuration. Which action should the administrator take FIRST to isolate the runtime issue?

Verify that the management interface has a valid route to the head office

Delete and recreate the tunnel interface to force a fresh negotiation

Reboot the firewall to clear any temporary session table corruption

Check the crypto profile and IKE gateway configuration for mismatched encryption algorithms or lifetimes

An administrator is committing a configuration that includes a new NAT rule. The commit fails with the error 'NAT rule is invalid: source zone and destination zone are the same.' The administrator intended to allow traffic between two different zones. What is the MOST likely cause of this error?

The source and destination zones were both set to the same zone by mistake

The NAT rule was created in the wrong rulebase (pre-NAT instead of post-NAT)

The NAT rule references an address object that does not exist

The NAT rule is missing a translation destination

A firewall is experiencing intermittent connectivity issues to a critical application server. The administrator reviews the system log and finds no obvious errors, but the traffic log shows that some sessions are being reset. Which log should the administrator examine NEXT to trace the root cause of the session resets?

The system log for 'high availability' (HA) failover events

The user-ID log to verify that the user is authenticated correctly

The threat log to check for intrusion prevention system (IPS) signatures that may be blocking the traffic

The configuration log to see if any recent changes were made to the application server's zone

A firewall is dropping traffic on a specific interface, and the administrator sees 'No route to host' errors in the system log. The interface is up, and the IP address is configured correctly. What is the MOST likely cause of this runtime error?

The interface is administratively down

The security policy is blocking the traffic

A missing or incorrect static route for the destination network
