問題 #65
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?
答案：C
解題說明：
A scalable Azure design for VM-Series uses load balancers with multiple active firewall instances rather than a fixed active/passive pair. Palo Alto Networks documents high-resiliency Azure deployments that use load balancers to distribute traffic across concurrent firewall instances, and Azure routing to the VM-Series relies on User-Defined Routes to steer traffic through the inspection path. That makes a load balancer-based autoscaling firewall cluster the correct architecture for increased cloud migration traffic and scalable inspection.
問題 #66
An organization is in the process of building a network infrastructure that is cloud first. Part of the revised architecture includes Prisma Access as demonstrated in the diagram below. The organization has selected Strata Cloud Manager (SCM) as the management method for Prisma Access and NGFWs deployed at the data center and in public cloud environments. There are 150 NGFWs in place that are used to terminate service connections and segment networks as well as to secure the data center and public cloud resources.
One of the resilience requirements is to provide highly available directory services and authentication for the NGFW and Prisma Access deployment.
The organization wants to be able to track Prisma Access users on the on-premises firewalls and remote networks.
Which configuration meets the design and organization requirements?
答案：D
解題說明：
Panorama distributes user-to-IP mapping information to on-premises firewalls through User-ID redistribution, while Prisma Access remote networks obtain user context from the Cloud Identity Engine. This combination ensures consistent and highly available user visibility across both on- premises NGFWs and Prisma Access environments.
問題 #67
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?
答案：A
解題說明：
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.
問題 #68
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.
In which two ways should the organization architect for isolation of IoT with groupings based on the device types? (Choose two.)
答案：B,C
解題說明：
Device-ID enables identification and classification of IoT devices based on attributes such as device type, allowing policy enforcement specific to those device categories. Dynamic address groups allow automatic grouping of devices based on tags or attributes, enabling scalable segmentation and isolation aligned with device type and function without manual updates.
問題 #69
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?
答案：A
解題說明：
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.
