Question 610
During a controlled ZIA, ZPA, or ZDX administration check, engineers discover: An IOC feed marks an IP address used by a shared hosting platform, and the security team plans to block the entire provider network without checking specific domains. Which configuration or architecture dependency accounts for the failure?
Explanation
Correct Answer
The underlying principle is: An IP reputation hit may represent shared infrastructure, so blanket network blocking can affect unrelated legitimate services. Address it by: Correlate the specific malicious domain, URL and connection evidence, then apply the narrow supported threat control. The confirmation is: The identified malicious service is denied while unrelated approved services at the shared provider remain reachable.
Incorrect Answers
Cloud App Control and URL filtering can have interacting order and cascading options; the final result depends on configured policy precedence. “Review supported cascade and filtering behavior and align both policy layers with the required application action” would remedy that alternative situation, but it would not correct the present issue: an IP reputation hit may represent shared infrastructure, so blanket network blocking can affect unrelated legitimate services.
“Scope the threat or bot-detection policy to the intended unmanaged cohort and add only justified monitored exceptions” is the supported response when group and location conditions control which clients receive threat actions; overbroad matching can treat approved automation as abuse. Here the decisive response is “Correlate the specific malicious domain, URL and connection evidence, then apply the narrow supported threat control”, so that different intervention does not meet the stated requirement.
Absence of a signature verdict is not evidence that an unknown file is safe; sandbox policy may require separate analysis or quarantine. “Configure the supported cloud sandbox submission and action appropriate for unknown high-risk file types and affected user groups” applies to that other condition. The reported evidence is an IOC feed marks an IP address used by a shared hosting platform, and the security team plans to block the entire provider network without checking specific domains; this alternative would address the wrong dependency.
