Question 40

How does the URL Filtering Categorization occur in the kernel?

1. RAD provides the status of the search to the client.

2. The a-sync request is forwarded to the RAD User space via the RAD kernel for online categorization.

3. The online detection service responds with categories and the kernel cache is updated.

4. The kernel cache notifies the RAD kernel of hits and misses.

5. URL lookup initiated by the client.

6. URL lookup occurs in the kernel cache.

7. The client sends an a-sync request back to RAD If the URL was not found.

Correct Answer: C

The URL Filtering Categorization process begins with the URL lookup initiated by the client, followed by the lookup occurring in the kernel cache. The kernel cache then notifies the RAD kernel of hits and misses. RAD provides the status of the search to the client. If the URL was not found, the client sends an a-sync request back to RAD. The a-sync request is forwarded to the RAD User space via the RAD kernel for online categorization. Finally, the online detection service responds with categories and the kernel cache is updated. Therefore, the correct sequence is 5, 6, 4, 1, 7, 2, 3.
