What is correct about the Resource Advisor (RAD) service on the Security Gateways?
A.
RAD is not a separate module, it is an integrated function of the ‘fw’ kernel module and does all operations in the kernel space
B.
RAD functions completely in user space. The Pattern Matter (PM) module of the CMI looks up for URLs in the cache and if not found, contact the RAD process in user space to do online categorization
C.
RAD is completely loaded as a kernel module that looks up URL in cache and if not found connects online for categorization. There is no user space involvement in this process
D.
RAD has a kernel module that looks up the kernel cache, notifies client about hits and misses and forwards a-sync requests to RAD user space module which is responsible for online categorization
The Resource Advisor (RAD) is not entirely a kernel module nor entirely in user space. It works in a hybrid manner where a kernel module handles cached URLs, and if the URL is not found in the cache, it forwards the request to a user-space process for online categorization. This setup ensures efficient caching and offloads the categorization process to the user space when necessary.
