Which statements are true about offloading antivirus inspection to a Security Processor (SP)?

The correct answer highlights that a replacement message cannot be presented to users when a virus has been detected. This is significant because, during antivirus inspection, if a virus is detected, the Security Processor (SP) executes the appropriate action specified in the firewall settings, such as blocking or quarantining the file. However, in this specific scenario regarding offloading to an SP, the capability of displaying a replacement message is not supported. This limitation stems from the way the SP processes traffic, often without being able to engage the standard user notification mechanisms that might be available in different modes of inspection.

To provide context, when an antivirus feature operates in a flow-based mode, it generally does not support the same level of user interaction as proxy-based inspection. Proxy-based modes are typically more interactive and capable of providing feedback, like replacement messages, but face performance limitations since they process traffic in a way that introduces latency. As a result, when offloading to an SP, the focus is on efficiency and CPU resource optimization, and notification features may be compromised for the sake of performance.

The other statements touch on various functionalities related to SP roles in handling antivirus inspection. For example, stating that both proxy-based and flow-based inspection are supported is incorrect because SPs usually excel at
