A regional office reports persistent throttling of a critical SaaS application during business hours.

Option D directly corrects both configuration problems shown by the evidence: the critical SaaS application has an overly restrictive class maximum, and lower-priority streaming traffic has excessive allocation. ZIA Bandwidth Control uses bandwidth classes and policy rules to allocate or limit traffic, so the administrator should revise the relevant class values and ensure that rule order produces the intended match. Zscaler’s Bandwidth Control overview and bandwidth-rule configuration guidance support managing allocations through classes and ordered rules. Firewall Insights can then confirm application usage and policy effects. A duplicate rule cannot bypass the existing class cap. A global increase wastes capacity and may worsen contention elsewhere. Sending logs to a SIEM may aid investigation, but delaying an evidence-supported correction leaves the known throttling condition unresolved.
