Palo Alto Networks PCSFE Exam Dumps

Traffic is directed to a Palo Alto Networks firewall integrated with Cisco ACI through a policy-based redirect. Cisco ACI is a software-defined network (SDN) solution that provides network automation, orchestration, and visibility. A policy-based redirect is a mechanism that allows Cisco ACI to redirect traffic from one endpoint group (EPG) to another EPG through a service device, such as a Palo Alto Networks firewall. The firewall can then inspect and enforce security policies on the redirected traffic before sending it back to Cisco ACI. Traffic is not directed to a Palo Alto Networks firewall integrated with Cisco ACI by using contracts between endpoint groups that send traffic to the firewall using a shared policy, through a virtual machine (VM) monitor domain, or by creating an access policy, as those are not valid methods for traffic redirection in Cisco ACI.

Security profiles are the components that scan for threats in allowed traffic. Security profiles are sets of rules or settings that define how the firewall will inspect and handle traffic based on various threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis. Security profiles can be applied to Security policy rules to enforce granular protection against known and unknown threats in allowed traffic. Intelligent Traffic Offload, TLS decryption, and NAT are not components that scan for threats in allowed traffic, but they are related features that can enhance security and performance.

Threat Prevention and WildFire are the two subscriptions that provide protection against malware and lateral movement in a private data center. Threat Prevention blocks known threats using antivirus, anti-spyware, and vulnerability protection. WildFire analyzes unknown files and links in a cloud-based sandbox and generates signatures for new threats. Intelligent Traffic Offload is a feature that reduces the load on the firewall by offloading traffic that does not need inspection. SD-WAN is a feature that optimizes the performance and availability of WAN connections.

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.

Kubernetes/Deployment Type/Environment is the structure of the YAML Ain't Markup Language (YAML) file repository. YAML is a human-readable data serialization language that is commonly used for configuration files. YAML file repository is a collection of YAML files that specify the resources and configuration for deploying and managing infrastructure components, such as firewalls, load balancers, networks, or servers. Kubernetes/Deployment Type/Environment is the structure of the YAML file repository that organizes the YAML files based on the following criteria:

Kubernetes: The platform that provides orchestration, automation, and management of containerized applications.

Deployment Type: The method or model of deploying and managing infrastructure components, such as Terraform, Ansible, Helm, or Kubernetes manifests.

Environment: The type or stage of the cloud or virtualization environment, such as development, testing, staging, or production. Deployment Type/Kubernetes/Environment, Kubernetes/Environment/Deployment Type, and Environment/Kubernetes/Deployment Type are not the structure of the YAML file repository, but they are related ways of organizing YAML files based on different criteria.
