NEW QUESTION # 57
The network security architect leading a Zero Trust migration has successfully completed identifying and classifying all mission-critical Data, Applications, Assets, and Services (DAAS).
The architect must now gather the necessary data to inform the technical design of the micro- perimeters and the placement of the VM-Series virtual firewalls in Azure. According to the Palo Alto Networks Zero Trust implementation methodology, what is the mandatory next step to gather the necessary data for designing the segmentation and the placement of security controls?
Answer: B
Explanation:
After identifying and classifying the protect surface (DAAS), the next mandatory step in the Zero Trust methodology is to map the transaction flows. This step captures how data, applications, assets, and services communicate, which directly informs how micro-perimeters should be designed and where VM-Series firewalls must be placed to enforce segmentation and control traffic effectively.
NEW QUESTION # 58
An organization with offices throughout the world has an SD-WAN solution in which all traffic is backhauled to a central set of data centers. Many of the offices have IoT / OT devices. Which IoT Security requirement must be taken into consideration by the security architect when determining which Zero Trust network solution will help this organization evolve its security architecture?
Answer: A
Explanation:
Accurate IoT/OT detection requires direct visibility into local network traffic where devices communicate. This is achieved when a Prisma SD-WAN ION or a Next-Generation Firewall is deployed at the site, enabling proper device identification and profiling based on observed traffic and network behavior.
NEW QUESTION # 59
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 resource allocation strategy should the architect use for the VM-Series virtual machine (VM)?
Answer: C
Explanation:
Reserving CPU and memory while pinning the VM to specific physical cores ensures deterministic performance by eliminating hypervisor contention, avoiding NUMA penalties, and guaranteeing consistent access to resources. This approach aligns with high-throughput, low- latency requirements and is essential for maintaining predictable performance in security-critical workloads handling encrypted traffic.
NEW QUESTION # 60
An organization wants to modernize its legacy branch architecture. The existing architecture is rigid, complex, and ill-suited for a cloud-first strategy, creating high operational costs and latency.
- The four core data centers are strategically located in Dallas, Toronto, London and Tokyo, and they are interconnected by a dedicated MPLS backbone providing reliable connectivity but incurring significant costs and offering limited bandwidth scalability.
- Branches rely on MPLS or site-to-site VPN to connect to the nearest geographical data center.
- All internet-bound traffic from the branches is backhauled to the data center egress firewalls.
This creates latency for SaaS applications and increases bandwidth strain on the MPLS links.
What is the primary security posture enhancement that can be achieved in this use case by offloading data center backhaul to a PAN-OS SD-WAN model with local internet breakout for SaaS traffic?
Answer: D
Explanation:
Offloading SaaS traffic from data center backhaul to PAN-OS SD-WAN with local internet breakout improves security posture primarily by enforcing visibility and granular policy control directly at the branch, where the traffic actually originates. PAN-OS SD-WAN is designed to secure direct internet access locally at branch sites instead of forcing SaaS traffic through centralized data center egress, which enables more precise application-aware inspection and control closer to users and devices.
NEW QUESTION # 61
An organization is designing the Prisma Access service connections for its data centers. Each data center has 10 Gb redundant links to the internet. Each data center will need to support a minimum of 1.5 Gbps of throughput from Prisma Access connected users and branches. Which diagram depicts a solution that meets the requirements of this use case?
Answer: A
Explanation:
This design uses ECMP across redundant ISP links with multiple active IPsec tunnels, allowing traffic to be load-balanced and aggregated. This ensures the required throughput (>1.5 Gbps) can be achieved while also providing high availability and resilience, aligning with best practices for Prisma Access service connections.
