Which actions are allowed for URL filtering on a FortiGate unit?

URL filtering on a FortiGate unit is designed to manage web traffic and establishes rules for how specific URLs should be handled. The actions that can be implemented include Allow, Block, Monitor, and Exempt.

The option Allow is used to permit access to specific URLs, enabling users to visit sites that are deemed appropriate. The Block action is utilized to deny access to certain URLs, preventing users from reaching sites that might contain harmful content or are otherwise inappropriate.

The Monitor action provides the capability to log access attempts to URLs, whether they are allowed or blocked. This is crucial for auditing and tracking user activity without necessarily enforcing restrictions. The Exempt action allows traffic to bypass the filtering rules, which can be useful in scenarios where certain users or applications need uninterrupted access to specific URLs despite general filtering policies.

Together, these four actions allow administrators to create a flexible and comprehensive URL filtering strategy that addresses varying security and accessibility needs. This explains why the selection that includes all four actions is the correct choice, as it encompasses the full range of functionalities available for URL filtering on a FortiGate unit.
