Basic Concept: Cloud Identity Engine can aggregate identity sources and segment identity data so only relevant users and groups are redistributed to the proper firewalls.

Why D is Correct: Segments within a single CIE tenant minimize overhead while filtering and redistributing only the identities each regional firewall group should receive.

Why A is Wrong: Create one CIE tenant, aggregate all identity data into a single view, and redistribute the full dataset to all firewalls. Rely on per-firewall Security policies to restrict access to out-of-scope user and group information. is a cloud deployment or routing approach, but it does not match the required managed insertion model, resilience pattern, or Panorama-controlled policy design in this scenario.

Why B is Wrong: Establish separate CIE tenants for each business unit, integrating each tenant with the relevant identity sources. Redistribute user and group data from each tenant only to the region’s firewalls, maintaining a strict one-to-one mapping of tenant to business unit. is a cloud deployment or routing approach, but it does not match the required managed insertion model, resilience pattern, or Panorama-controlled policy design in this scenario.

Why C is Wrong: Disable redistribution of identity data entirely. Instead, configure each regional firewall to pull user and group details directly from its local identity providers (IdPs). is a cloud deployment or routing approach, but it does not match the required managed insertion model, resilience pattern, or Panorama-controlled policy design in this scenario.
