Question 570
During a Zscaler Zero Trust Exchange troubleshooting session, the team finds: Only laptops running a recent operating-system update show high CPU use and poor collaboration scores, but the network operations team plans a branch router replacement. What assurance step should be included in future changes?
Explanation
Correct Answer
This safeguard mitigates device-level performance event after laptop update: Compare device cohorts and software change windows before attributing all user-experience alarms to network infrastructure. The risk being controlled is: Endpoint health can independently degrade digital experience while network path and ZIA policy remain healthy. A safeguard for an unrelated failure would not address it.
Incorrect Answers
An access-policy evaluation, tunnel setup and completed private application transaction are distinct stages with different outcome evidence. “Define success metrics based on specific ZPA fields and avoid counting every connection attempt as completed app usage” would remedy that alternative situation, but it would not correct the present issue: endpoint health can independently degrade digital experience while network path and ZIA policy remain healthy.
“Capture representative healthy ZDX path baselines for key SaaS applications and major locations” is the supported response when a permitted security policy action does not identify which endpoint, Wi-Fi, ISP or application hop introduces delay. Here the decisive response is “Compare device cohorts and software change windows before attributing all user-experience alarms to network infrastructure”, so that different intervention does not meet the stated requirement.
Low transport latency does not exclude slow application processing or browser transaction behavior at the destination service. “Use separate network and app timing measures in incident dashboards instead of one generic slowness indicator” applies to that other condition. The reported evidence is only laptops running a recent operating-system update show high CPU use and poor collaboration scores, but the network operations team plans a branch router replacement; this alternative would address the wrong dependency.
