An organization wants to migrate to an SSE model using Prisma Access for hybrid workforce connectivity. Following bandwidth analysis, network engineers have identified high-bandwidth requirements (>2 Gbps) sustained throughput to the data center for privately hosted applications (e.g., three tier applications active FTP and SMB file servers, EDR toolsets).Business continuity for the organization requires the ability to use multiple cloud providers for private-application connectivity, ensuring no single cloud provider outage can disrupt operations. The network operations team has expressed concerns about migrating to SSE with legacy routing technical debt noting multiple redistribution protocols in place across the environment.Which two network connectivity methods will meet the business requirements to access private applications from Prisma Access? (Choose two.)

A global organization has fully adopted Prisma Access to provide security for its mobile workforce and remote offices, and user identity is managed in Okta. The security team wants to create consistent Security policies that grant access to specific SaaS applications based on a users' departments, regardless of whether they work from home or a from branch office connected via an SD-WAN deviceWhich architecture ensures that consistent user-to-group mapping is available to Prisma Access for policy enforcement in this use case?

A global organization is modernizing its data center and private cloud infrastructure. The environment consists of:- A Nutanix AHV cluster hosting critical east-west application workloads- A VMware ESXi cluster with multi-socket hosts, supporting high-throughput workloads (>10 Gbps)- A new pair of PA-5450 firewalls to secure the perimeter and handle encrypted traffic inspection at scale- Strict performance service-level agreements (SLAs) for both north-south and east-west flows, with heavy reliance on TLS 1.3 and IPSec- A Network Functions Virtualization (NFV) environment on KVM to provide high-performance security services to maximize packet throughput and minimize latency The chief architect is tasked with ensuring that the firewall design avoids hypervisor contention optimizes non-uniform memory access (NUMA) and uses hardware features for encrypted traffic.VM-Series on Nutanix AHV - Resource Allocation- Because the Nutanix cluster is already heavily used, the architect's main concern is preventing performance degradation of the virtual firewall. Thin provisioning or ballooning could introduce latency and unpredictability which is unacceptable for a security-sensitive workload.VM-Series on VMware ESXi - NUMA and vCPU Placement- In the VMware ESXi environment, the architect is deploying VM-Series for workloads pushing >10 Gbps. Assigning vCPUs across NUMA nodes or oversubscribing cores would create latency due to cross-socket memory access and scheduling delays. Similarly, dedicating logical hypethreads does not provide the deterministic data plane performance required.Operational Integration and High Availability- With performance guaranteed by correct hypervisor and hardware provisioning, the architect also considers high availability (HA). VM-Series pairs are deployed in active/passive HA across Nutanix and VMware clusters, while PA-5450s form the data center's north-south secure perimeter deployment. This ensures resilience without introducing unnecessary east-west inspection bottlenecks.- The recommendation must be a scalable, high-performance firewall deployment aligned with enterprise SLAs and the CISO's encrypted traffic concerns.Which PAN-OS feature will meet the CISO's need for north-south traffic inspection?

A large organization is building a hybrid AI environment. The plan is to develop proprietary machine learning (ML) models on-premises in a VMware NSX environment and create separate, cloud-native AI applications in a Google Kubernetes Engine (GKE) cluster environment. The CISO has requested a single solution that can offer runtime protection and visibility for the two environments. Which Prisma AIRS component or form factor should a security architect recommend to this customer?

A global organization is in the process of securing critical applications during a cloud-based migration while migrating to a cloud-first design, and it is currently performing a brownfield migration of its most critical applications - such as CRM and product intellectual property / design systems - into Azure Cloud. The organization already has an active/passive high availability (HA) NGFW deployed at its data center with multiple zones and has replicated that design into its existing Azure HA deployment.The organization recognizes the need to modernize its security posture as critical workloads move out of the data center and users connect from anywhere. Its security model is defined by a traditional "hard shell, soft center" approach:Zero Trust Gaps- Current network segmentation is perimeter-based. The organization wants to expand Zero Trust principles across cloud and on-premises environments.- The network relies heavily on VLANs and IP address-based Access Control Lists (ACLs) segmented primarily by office location and broad departmental groups.- Once employees are on the corporate network (i.e., inside the "perimeter"), they have relatively wide access.- If attackers compromise a single endpoint (e.g., via a phishing email), they can easily move laterally and scan for high-value targets.Cloud Blind Spots- The organization uses Azure for its production environments and hosts applications that contain sensitive customer data.- Security controls in the cloud are often managed independently of the on-premises network.Access is frequently granted with overly permissive identity and access management (IAM) roles and keys based on the resource rather than the user's real-time context or application health.Remote User Access- Many remote users are still hairpinning into the corporate data center just to reach internet or SaaS resources, creating latency and inefficiency.- Traditional VPN is used for remote employees.- The VPN grants access to the entire internal network segment making the remote endpoint the new, weaker perimeter. There is no continuous check on the user's device health after the initial connection.Visibility and Logging- Logs are primarily stored on-premises, then forwarded to a local Security Information and Event Management (SIEM) solution. As applications move to Azure, visibility into cloud traffic and user behavior becomes fragmented.Data Security Concern- Sensitive data, including product design files, will now live in SaaS and cloud environments. The organization needs data security to prevent leakage and enforce compliance.Ingress Security- Third-party partners and suppliers require access into the data center and cloud applications, introducing risk at ingress points.The current Microsoft Azure NGFW architecture will not support the increased traffic with the new applications being migrated.Which architectural solution will provide scalable inspection?

An organization has selected Prisma SD-WAN ION devices for use at branch offices and is working to build a low-level design for its sites. A typical branch site has a 10 Mbps MPLS with fiber LC-SR, and an RJ-45 Ethernet 50 Mbps DIA internet circuit.There are 75 workstations and a stacked core switch that supports LACP, M-LAG, BGP, and OSPF will be used. The core switch is the default gateway for all local VLANs. The final design will determine the selection of the appropriate model and accessories for the site.Which statement applies to the Prisma SD-WAN architecture in this use case?
