Network traffic coining from an organization's CEO must never be denied. Which access control policy configuration option should be used if the deployment engineer is not permitted to create a rule…

The correct answer is C. Configure a trust policy for the CEO. To ensure a CEO's network traffic is never denied without creating an 'allow all' rule, a trust policy specifically for the CEO's traffic should be configured.

Why each option

To ensure a CEO's network traffic is never denied without creating an 'allow all' rule, a trust policy specifically for the CEO's traffic should be configured.

AConfigure firewall bypass.

Configuring a complete firewall bypass typically means traffic doesn't even hit the firewall, which might not be an available or desirable option and may lack visibility. A trust rule is a specific configuration within the firewall.

BChange the intrusion policy from security to balance.

Changing an intrusion policy from security to balance would loosen security checks, but does not guarantee traffic will never be denied, as other rules or conditions could still block it.

CConfigure a trust policy for the CEO.Correct

A trust policy in an Access Control Policy explicitly tells the Firepower Threat Defense (FTD) device to allow traffic matching that rule without further inspection, including intrusion prevention and file policies. This ensures the traffic is always permitted, bypassing security checks that might otherwise deny it.

DCreate a NAT policy just for the CEO.

Creating a NAT policy is for network address translation and has no bearing on whether traffic is denied by security policies.
