46. Frage
A multinational organization has a large worldwide remote user base. This user base consists of several persona types with distinct requirements and concerns regarding the adoption of a Zero Trust Network Access (ZTNA) solution.
- Developers have a requirement to temporarily bypass security controls for business purposes, but the security team sees this as a potential risk. The developers commonly access development servers onsite in private data centers and public cloud. These development applications use web (HTTP/HTTPS), API, RPC, and SMB-based applications.
- Sales staff travel regularly and connect to the network via many different types of connections, but they are generally limited to SaaS-based web applications. They often complain about performance when any agent is installed and want the ability to temporarily disable these agents.
Data exfiltration and insider risk have been identified as the primary threats for this class of user.
- Executives have concerns about being high-value targets. Security must be consistent across the multiple endpoint types, including mobile and desktop devices. The executive team members have indicated that their primary objective is to ensure that the solution is responsive and easy to troubleshoot.
Which two parameters should the architect take into account regarding GlobalProtect gateway selection? (Choose two.)
Antwort: B,C
47. Frage
An architect is reviewing a use case with the following requirements:
- Visibility on the health of an end user's path for the five most
critical applications
- Metrics on the impact of endpoint health for application
- Centralized call quality analytics from Zoom video conferencing
solution
- Insights into the supporting protocols, such as DNS
- Support 600 users on Windows desktops in a single sales office
Which solution should be recommended to meet these requirements?
Antwort: B
Begründung:
ADEM with a remote network and an ION device is the best fit for a single office deployment because it provides end-to-end visibility for branch users and applications, including path monitoring for critical apps and insight into supporting services such as DNS. Palo Alto Networks also states that ADEM for remote sites is supported on Prisma SD-WAN remote sites with ION platforms, and ADEM's Zoom integration delivers centralized meeting quality analytics correlated with network and endpoint factors. This aligns with the requirement to monitor user experience for a 600-user Windows-based sales office from a centralized view.
48. Frage
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?
Antwort: A
Begründung:
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.
49. Frage
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 architectural component ensures the IoT storage, integrity, and non-repudiation of this granular risk data for auditing purposes?
Antwort: A
Begründung:
Strata Logging Service provides centralized, cloud-based log storage with integrity and non- repudiation guarantees, ensuring that IoT telemetry and security logs are preserved for auditing.
It scales to handle high throughput environments and supports long-term retention and analysis, which is required for tracking devices with critical CVE scores across large, distributed deployments.
50. Frage
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.
While using the VM-Series to build the NFV environment, which configuration should the architect use?
Antwort: A
Begründung:
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.
