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

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

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.)

• A. Proximity to destination resources
• B. Proximity to users
• C. Gateway priority
• D. Gateway geo IP mapping
