問題 #59
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 PAN-OS feature will meet the CISO's need for north-south traffic inspection?
答案：C
解題說明：
Dedicated hardware crypto engines on the PA-5450 offload SSL/TLS decryption and IPSec processing from the main CPU, enabling high-performance inspection of encrypted north-south traffic. This ensures the firewall can meet strict SLAs while handling heavy TLS 1.3 and IPSec workloads efficiently.
問題 #60
You must protect against command-and-control traffic using DNS tunneling. Which feature helps MOST?
答案：D
解題說明：
DNS Security detects malicious DNS patterns, including tunneling and C2 communication. It provides advanced analytics beyond simple URL filtering.
問題 #61
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.
Which traffic flow is valid for administrators connecting network equipment over SSH hosted in the data center?
答案：C
解題說明：
SSH is not an HTTP/HTTPS application, so it does not use the explicit proxy path. For administrators connecting from Prisma Browser to network equipment hosted in the data center, the valid flow is through the mobile user path into Prisma Access, then across the service connection to the data center, and finally to the target device. This matches the IPSec/SSL connectivity shown for Prisma Browser-based user access to private applications.
問題 #62
An architect is designing a security solution for a large AWS environment with numerous application virtual private clouds (VPCs). These applications have diverse and sometimes conflicting inbound security requirements, making a single, unified ruleset challenging to create and maintain. The solution must secure inbound traffic for different application groups while also centrally securing all outbound and east-west traffic via an AWS Transit Gateway. Which design model recommendation will simplify rule complexity for inbound traffic while meeting all security requirements?
答案：B
解題說明：
A combined model is designed for environments where inbound requirements differ across application groups. It uses dedicated inbound firewalls for those logical application groups, which keeps inbound policy sets simpler and easier to manage, while a central NGFW tied to the Transit Gateway secures outbound and east-west traffic centrally. Palo Alto Networks documents this combined deployment pattern specifically as using inbound security at the application VPC side and the transit gateway as the hub for east-west and outbound security.
問題 #63
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：D
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.
