Which setting ensures that the Protection Module is provided by the Deep Security Agent if the Virtual Appliance is unavailable?

The choice denoted by "C" refers to the setting that allows the Protection Module to be supplied by the Deep Security Agent in situations where the Virtual Appliance is inaccessible. Under the "Appliance Preferred" setting, the system aims to utilize the Virtual Appliance for protection and security tasks when it is available. However, in circumstances where the Virtual Appliance cannot be reached, the Deep Security Agent steps in to provide the necessary protection, ensuring that security measures remain in place without interruption.

This configuration is vital for maintaining continuous security coverage. In environments where the availability of virtual resources can fluctuate, having the agent act as a fallback enhances resilience and ensures that critical security functions are not compromised. The other settings may prioritize one method over the other under specific conditions, which could lead to a lapse in protection if the preferred method is unavailable. The "Appliance Preferred" setting effectively addresses this by ensuring a seamless transition to the agent when needed, thereby safeguarding the virtual environment consistently.
