問題 #1
An architect must design secure remote access for users. Which solution is MOST appropriate?

A. VLAN segmentation
B. NAT only
C. Static routing
D. GlobalProtect

問題 #2
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?

A. Virtio drivers and DPDK mode enabled
B. SR-IOV-enabled network interfaces and standard Linux bridge networking
C. SR-IOV-enabled network interfaces and DPDK mode enabled
D. Virtio drivers connected to an Open vSwitch (OVS) bridge

Which resource allocation strategy should the architect use for the VM-Series virtual machine (VM)?

A. Enable memory overcommitment (ballooning) on the VM to allow the hypervisor to reclaim unused memory for other workloads.
B. Use thin provisioning for the VM's virtual disks to save storage space and allow for flexible growth.
C. Implement CPU and memory reservation for the VM, pinning it to specific physical cores and reserving 100% of its allocated RAM.
D. Configure the VM with a high-priority setting in the AHV scheduler to ensure it gets preferential access to CPU cycles.

問題 #4
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.
The organization requires a proposal for a new WAN architecture for branch connectivity with the goal of improving security posture and SaaS application access as well as supporting local internet breakout for all branch devices, including IoT.
Which two implementations will achieve the goal of modernizing the branch architecture?
(Choose two.)

A. SASE with Prisma Access for remote networks and service connections
B. NGFW at each branch with Large Scale VPN (LSVPN) for data center access and Direct Internet Access (DIA)
C. SD-WAN using on-premises NGFWs for Direct Internet Access (DIA)
D. SSE with Prisma Access for mobile users and service connections

問題 #5
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 statement applies in the context of securing the developers' applications?

A. ZTNA Connector requires DNS for all applications it publishes and does not permit direct IP address-based access
B. GlobalProtect mobile users and explicit proxy users share the same configuration scope for policy configuration
C. Explicit proxy on ramps can only provide security for HTTP, HTTPS, and proxy-aware applications
D. Mobile users, remote networks, and explicit proxy all provide the same Cloud-Delivered Security Services (CDSS) capabilities.
