Exam ZDTA Topic 1 Question 14 Discussion

The feature that allows Zscaler to apply URL filtering even when a Cloud App control policy explicitly permits a transaction is calledAllow Cascading. This feature ensures that even if a cloud application is permitted by the Cloud App control policy, the URL filtering policy can still be enforced. This is useful in cases where granular URL control is needed on top of cloud app permissions, providing layered security controls.
The study guide clearly explains that Allow Cascading enables URL filtering policies to cascade or take precedence and thus still inspect and potentially block URLs even if the cloud app is allowed by policy. This allows administrators to fine-tune access and ensure additional inspection layers on web traffic .
