Question 360
Before accepting a Zscaler configuration change, the team discovers: An emergency global block to stop one threat actor accidentally denies a shared destination needed by a production payment service and the team has no clear rollback. What is the controlling reason for these observations?
Explanation
Correct Answer
The underlying principle is: A broad blocking action against shared infrastructure can create unacceptable collateral impact when indicator scope and recovery controls are missing. Address it by: Validate the actual malicious domain or URL, narrow the rule and apply the approved rollback while preserving verified incident protection. The confirmation is: The payment service recovers and test traffic to the verified malicious indicator remains blocked and logged.
Incorrect Answers
Bandwidth policy class selection and location capacity can restrict legitimate application throughput regardless of access permission. “Check actual traffic classification, per-location limits and bandwidth-control hierarchy before rebalancing the approved classes” would remedy that alternative situation, but it would not correct the present issue: a broad blocking action against shared infrastructure can create unacceptable collateral impact when indicator scope and recovery controls are missing.
“Inspect ZDX application and endpoint metrics alongside ZPA connector and target service health for the affected users” is the supported response when authorization success proves access permission, not successful or fast application transactions through the entire endpoint-to-app path. Here the decisive response is “Validate the actual malicious domain or URL, narrow the rule and apply the approved rollback while preserving verified incident protection”, so that different intervention does not meet the stated requirement.
An endpoint-specific performance problem can arise from local CPU, memory, DNS or Wi-Fi driver behavior even when the shared upstream path is healthy. “Compare ZDX device health and app probes for affected and unaffected peers before changing shared network routing” applies to that other condition. The reported evidence is an emergency global block to stop one threat actor accidentally denies a shared destination needed by a production payment service and the team has no clear rollback; this alternative would address the wrong dependency.
