NEW QUESTION # 13
An organization intends to deploy a complete SASE architecture comprising Prisma SD-WAN IONs at branches and data centers, together with Prisma Access remote networks, service connections, and mobile users.
The business office team requires traffic from global remote offices to the public cloud to be of the highest criticality. This traffic must receive the highest SLA and QoS priority while retaining a balanced level of threat inspection.
Which recommendation should the architect make to deliver the lowest latency, highest throughput, and greatest resilience for the applications?
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Palo Alto Networks Network Security Architect:
For branch workloads communicating with public-cloud environments (such as AWS, Azure, or GCP), routing through intermediary hubs or hairpins introduces latency penalties and throughput bottlenecks.
Deploying Prisma SD-WAN virtual IONs (vIONs) directly within the public cloud environment (e.g., integrated into an AWS Transit Gateway or Azure Virtual WAN hub) integrates cloud-hosted applications directly into the SD-WAN fabric.
This topology enables end-to-end Application-Defined SD-WAN intelligence directly from branch physical IONs to the cloud vIONs. The vION establishes native BGP peering with the cloud provider's internal routing tables, learning workload VPC prefixes dynamically. Prisma SD-WAN's AppFabric continuously measures Layer 7 metrics (packet loss, jitter, latency) and enforces strict per-application SLA and QoS policies across multiple direct WAN transport paths. If an internet path degrades, sub-second failover redirects business- critical traffic to alternate connections without dropping TCP sessions, delivering low latency and high throughput without requiring tromboning through on-premises data centers.

NEW QUESTION # 14
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?
Answer: C
Explanation:
In this design, the MPLS circuit is being terminated by the ION. If that device loses power, the MPLS path also goes down because the branch loses the device that is physically terminating and forwarding that private WAN connection. Prisma SD-WAN does support using private WAN and internet paths actively, so the issue is not coexistence of MPLS and DIA. It also supports LAN-side BGP beyond just advertising a default route, and LAG/LACP can bundle multiple LAN interfaces rather than being limited to only two.
NEW QUESTION # 15
A company wants to reduce false positives in threat detection while maintaining strong security.
What should they do?
Answer: D
Explanation:
Tuning security profiles and creating exceptions reduces false positives while maintaining protection. Disabling profiles or allowing all traffic compromises security.
NEW QUESTION # 16
A global organization is upgrading its data center and private-cloud infrastructure. The environment includes:
A Nutanix AHV cluster that hosts critical east-west application workloads A VMware ESXi cluster with multi-socket hosts that supports high-throughput workloads ( > 10 Gbps) A new pair of PA-5450 firewalls to secure the perimeter and perform 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 that provides high-performance security services to maximize packet throughput and minimize latency The chief architect must ensure 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 utilized, the architect's primary concern is avoiding performance degradation of the virtual firewall. Thin provisioning or ballooning can 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 exceeding 10 Gbps.
Assigning vCPUs across NUMA nodes or oversubscribing cores would add latency because of cross-socket memory access and scheduling delays. Likewise, dedicating logical hypethreads does not deliver the deterministic data-plane performance required.
Operational Integration and High Availability
With performance ensured through proper 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 provide the data center's north-south secure-perimeter deployment. This provides resilience without adding unnecessary east-west inspection bottlenecks.
The recommendation must be a scalable, high-performance firewall deployment that aligns with enterprise SLAs and the CISO's encrypted-traffic concerns.
Which PAN-OS feature satisfies the CISO's requirement for north-south traffic inspection?
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Palo Alto Networks Network Security Architect:
The PA-5450 chassis is built upon a modular, distributed architecture comprising Data Processor Cards (DPC) and Networking Interface Cards (NIC) connected across a high-speed backplane. Inspecting line-rate north-south traffic containing pervasive TLS 1.3 encryption and termination of bulk IPSec tunnels places severe mathematical compute burdens on standard processor cores.
To ensure deterministic multi-gigabit throughput under full Content-ID and Threat Prevention inspection without violating latency SLAs, the PA-5450 integrates dedicated hardware-based cryptographic engines on its data processing architecture. These Application-Specific Integrated Circuits (ASICs) handle asymmetric key exchange offload (RSA/ECDSA handshake processing) and symmetric bulk cipher encryption/decryption (AES-GCM/ChaCha20-Poly1305) directly in silicon. Offloading computationally heavy cryptographic operations to dedicated hardware processors protects general data-plane CPU cores, ensuring that Single-Pass inspection, App-ID, and anti-malware filtering maintain wire-speed processing.

NEW QUESTION # 17
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: A
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.
