Master Palo Alto Networks PCSFE Exam with Reliable Practice Questions

Correct : B

CN-Series firewall is the Palo Alto Networks firewall that provides network security when deploying a microservices-based application. A microservices-based application is an application that consists of multiple independent and loosely coupled services that communicate with each other through APIs. A microservices-based application requires network security that can protect the inter-service communication from cyberattacks and enforce granular security policies based on application or workload characteristics. CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. CN-Series firewall can provide network security when deploying a microservices-based application by inspecting and enforcing security policies on traffic between containers within a pod, across pods, or across namespaces in a Kubernetes cluster. PA-Series, VM-Series, and HA-Series are not Palo Alto Networks firewalls that provide network security when deploying a microservices-based application, but they are related solutions that can be deployed on different platforms or environments.

Correct : A

The appropriate file format for Kubernetes applications is .yaml. YAML is a human-readable data serialization language that is commonly used for configuration files. Kubernetes applications are defined and deployed using YAML files that specify the desired state and configuration of the application components, such as pods, services, deployments, or ingresses. YAML files for Kubernetes applications follow a specific syntax and structure that adhere to the Kubernetes API specifications. .exe, .json, and .xml are not appropriate file formats for Kubernetes applications, but they are related formats that can be used for other purposes.

Correct : B

TLS decryption is the offering that inspects encrypted outbound traffic. TLS decryption is a feature that allows the firewall to decrypt and inspect outbound SSL/TLS traffic from internal clients to external servers. TLS decryption can inspect encrypted outbound traffic by applying threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis, to the decrypted traffic and blocking any malicious content or activity. WildFire, Content-ID, and Advanced URL Filtering (AURLF) are not offerings that inspect encrypted outbound traffic, but they are related solutions that can enhance security and visibility.

Correct : A, D

The two features of CN-Series firewalls that protect east-west traffic between pods in different trust zones are:

Intrusion prevention system

Layer 7 visibility

East-west traffic is the traffic that flows between applications or workloads within a network or a cloud environment. Pods are the smallest units of deployment in Kubernetes, consisting of one or more containers that share resources and network space. Trust zones are segments of the network or the cloud environment that have different levels of security requirements or policies based on data sensitivity, user identity, device type, or application function. CN-Series firewalls are containerized firewalls that integrate with Kubernetes and provide visibility and control over container traffic. Intrusion prevention system is a feature of CN-Series firewalls that protects east-west traffic between pods in different trust zones by detecting and blocking known exploits and vulnerabilities using signature-based and behavior-based methods. Layer 7 visibility is a feature of CN-Series firewalls that protects east-west traffic between pods in different trust zones by identifying and classifying applications and protocols based on their content and characteristics, regardless of port, encryption, or evasion techniques. Communication with Panorama and external load balancer are not features of CN-Series firewalls that protect east-west traffic between pods in different trust zones, but they are related features that can enhance management and performance.

Correct : A

CN-Series firewalls are licensed by data-plane vCPU. Data-plane vCPU is the number of virtual CPUs assigned to the data plane of the CN-Series firewall instance. The data plane is the part of the CN-Series firewall that processes network traffic and applies security policies. CN-Series firewalls are licensed by data-plane vCPU, which determines the performance and capacity of the CN-Series firewall instance, such as throughput, sessions, policies, rules, and features. CN-Series firewalls are not licensed by service-plane vCPU, management-plane vCPU, or control-plane vCPU, as those are not factors that affect the licensing cost or consumption of CN-Series firewalls.
