  - Because Prisma Access egress IP addresses can change as the platform autoscales or as infrastructure upgrades occur, a customer relying on those dynamic addresses for SaaS provider IP allow-listing faces recurring operational overhead every time an address changes - and the specific concern raised in the question is about the time and effort involved in keeping those SaaS-side allow-lists current during and after onboarding. The Dedicated IP Addresses feature directly addresses this by letting the customer request and be assigned static, non-changing egress IP addresses for their tenant, which they then submit once to their SaaS providers for allow-listing, eliminating the need for ongoing IP list maintenance and the associated update lag entirely. This makes option D the correct, purpose-built answer. Dynamic IP pooling (option A) is not a real Prisma Access mitigation feature for this concern, and the very word " dynamic " runs counter to what the customer is asking to avoid. DNS-based load balancing (option B) is a general traffic-distribution technique unrelated to the stability of egress IP addresses used for SaaS allow-listing. Traffic steering (option C) is a distinct capability used to direct internet-bound traffic to specific service connections or paths based on defined criteria - it governs where traffic is routed, not the underlying stability of the egress IP address a SaaS provider would see, so it does not solve the allow-list churn problem described.
