NEW QUESTION # 15
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.
To optimize throughput and minimize latency, what is recommended to configure the vCPUs and NUMA for this deployment?
Answer: C
Explanation:
To optimize throughput and minimize latency, the VM-Series data plane vCPUs should stay within a single physical NUMA node. Palo Alto Networks performance guidance specifically recommends isolating CPU resources in one NUMA node to avoid cross-node memory access penalties and reduce scheduling overhead, which is especially important for high-throughput ESXi deployments.
NEW QUESTION # 16
An organization plans to deploy a full SASE architecture consisting of Prisma SD-WAN IONs at branches and data centers alongside Prisma Access remote networks, service connections, and mobile users. The business office team requires that traffic from global remote offices to public cloud is of highest criticality, and this traffic should have the greatest service-level agreement (SLA) and QoS priority while still maintaining a balance of threat inspection. Which recommendation should the architect make to provide the lowest latency, highest throughput, and greatest resilience for the applications?
Answer: D
Explanation:
Deploying Prisma SD-WAN IONs in the public cloud gives remote offices the most direct path to cloud-hosted applications, which is the best fit for lowest latency and highest throughput. Prisma SD-WAN is built around application-aware path selection, QoS, and performance policy so traffic can be prioritized by business criticality and moved to a better path when SLA metrics such as latency, loss, or jitter are violated. Palo Alto Networks also supports BGP on branch and data center ION devices, including public-cloud deployments through its cloud integrations, which provides resilient routing to cloud application environments.
NEW QUESTION # 17
A global manufacturing organization has a strategic plan for rapid growth through mergers and acquisitions Several components the organization has purchased are deemed large deployments with existing IP address schemas and allocations that conflict with the parent organization. The manufacturing organization needs access to the resources before a re-IP initiative can be completed.
All of the deployments include a variety of IoT devices Leadership requires protection of vulnerable assets and identification of any known CVEs associated with the IoT devices. The governance, risk and compliance (GRC) team requires comprehensive non-repudiable logs to identify all IoT devices reporting "Critical (9 0+) CVE scores" for mandatory remediation.
Throughput needs to exceed the current 1 Gbps trending rate, and with expected growth will soon scale to 5 Gbps.
Segmentation is a mandatory requirement with enclaves based on region, device type, and function.
Which off-ramp should an architect recommend to meet the requirements of the organization?
Answer: B
Explanation:
Colo-Connect provides high-throughput, private connectivity between Prisma Access and on- premises or data center environments, supporting multi-gigabit requirements (scaling beyond 1 Gbps toward 5 Gbps). It is designed for large-scale, high-performance environments and supports segmentation and secure access without requiring immediate re-IP, making it the best fit for this scenario.
NEW QUESTION # 18
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.
Which solution will improve resilience and reduce operational overhead in this scenario?
Answer: D
Explanation:
Cloud NGFW integrated into the existing VNet design improves resilience and reduces operational overhead because it delivers managed, cloud-native firewall protection directly for Azure VNet traffic without the customer having to operate and scale VM-based firewall infrastructure. Palo Alto Networks documents Cloud NGFW for Azure as protecting Azure Virtual Network traffic through centrally managed rulestacks, which aligns with the need for simpler operations while supporting a growing cloud-first environment

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.
While using the VM-Series to build the NFV environment, which configuration should the architect use?
Answer: B
Explanation:
For a high-performance NFV deployment on KVM, the VM-Series should use SR-IOV-enabled interfaces together with DPDK. Palo Alto Networks documents DPDK as improving packet- processing speed by bypassing the Linux kernel, and its KVM guidance explicitly calls out enabling both DPDK and SR-IOV for maximum VM-Series performance. This combination best fits the requirement to maximize throughput and minimize latency in an NFV environment.
