Play an AI-generated podcast conversation about this lesson

What action does the Block Rule take?

Drops matching traffic (correct)

Rate-limits traffic

Bypasses DV inspection

Allows matching traffic

When is the Trust rule used?

When traffic needs to be rate-limited

When traffic is from external users

When performance optimization is needed (correct)

When traffic is inspected against DV filters

In what scenario would the Allow Rule be applied?

When traffic is inspected against DV filters (correct)

When the traffic needs to be rate-limited

When no further inspection is required once matched

When external users attempt to access web servers
