In which posture operational mode is the client notified of failure results and given the option to continue to bypass the posture assessment policy?

The correct choice highlights the Optional posture operational mode, where clients are informed of any failures in the posture assessment policy but are also given the choice to bypass these failures. This mode allows users to continue with network access even if they do not meet all security requirements.

In an Optional mode scenario, the user can make an informed decision about whether to comply with the security policies or to proceed despite failing the assessment. This approach offers flexibility for users who may not have the ability to meet all posture requirements immediately but still need network access for legitimate reasons, such as performing critical work.

In contrast, other operational modes implement stricter policies. For instance, Mandatory mode does not allow users to bypass posture checks, making access contingent upon full compliance. Audit mode focuses on monitoring compliance without enforcing restrictions or actions based on assessment results, while Passive mode quietly monitors and assesses posture without actively helping or hindering user experience regarding access. Thus, each mode serves different purposes in managing network security and user access, with Optional mode specifically designed to provide users with a choice in the event of failure.
