NEW QUESTION # 31
How does a CN-Series firewall prevent exfiltration?
- A. It inspects outbound traffic content and blocks suspicious activity.
- B. It distributes incoming virtual private cloud (VPC) traffic across the pool of VM-Series firewalls.
- C. It provides a license deactivation API key.
- D. It employs custom-built signatures based on hash
Answer: A
Explanation:
CN-Series firewall prevents exfiltration by inspecting outbound traffic content and blocking suspicious activity. Exfiltration is a technique used by attackers to steal sensitive data or assets from a compromised network or system, usually by sending them to an external destination, such as a command and control server, a drop zone, or an email address. CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. CN-Series firewall prevents exfiltration by inspecting outbound traffic content and blocking suspicious activity using threat prevention technologies, such as antivirus, anti-spyware, vulnerability protection, URL filtering, file blocking, data filtering, and WildFire analysis. CN-Series firewall does not prevent exfiltration by employing custom-built signatures based on hash, distributing incoming virtual private cloud (VPC) traffic across the pool of VM-Series firewalls, or providing a license deactivation API key, as those are not valid or relevant methods for exfiltration prevention.

NEW QUESTION # 32
Which element protects and hides an internal network in an outbound flow?
- A. DNS sinkholing
- B. NAT
- C. User-ID
- D. App-ID
Answer: B
Explanation:
NAT is the element that protects and hides an internal network in an outbound flow. NAT is a feature that translates the source or destination IP address or port of a packet as it passes through the firewall. NAT can protect and hide an internal network in an outbound flow by replacing the private IP addresses of the internal hosts with a public IP address of the firewall or another device, making them appear as a single entity to the external network. This prevents external hosts from directly accessing or identifying the internal hosts, and also conserves the public IP address space. DNS sinkholing, User-ID, and App-ID are not elements that protect and hide an internal network in an outbound flow, but they are related features that can enhance security and visibility. Reference: Palo Alto Networks Certified Software Firewall Engineer (PCSFE), [NAT Overview], [DNS Sinkholing Overview], [User-ID Overview], [App-ID Overview]
NEW QUESTION # 33
Which two features of CN-Series firewalls protect east-west traffic between pods in different trust zones? (Choose two.)
- A. Layer 7 visibility
- B. External load balancer
- C. Intrusion prevention system
- D. Communication with Panorama
Answer: A,C
Explanation:
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.

NEW QUESTION # 34
Which two mechanisms could trigger a high availability (HA) failover event? (Choose two.)
- A. Heartbeat polling
- B. Ping monitoring
- C. Session polling
- D. Link monitoring
Answer: A,D
Explanation:
Heartbeat polling and link monitoring are two mechanisms that can trigger an HA failover event. Heartbeat polling is a method of verifying the health of the peer firewall by sending periodic heartbeat messages. If the heartbeat messages are not received within a specified interval, the firewall assumes that the peer is down and initiates a failover. Link monitoring is a method of verifying the connectivity of the interfaces on the firewall by sending link state packets. If the link state packets are not received on a specified number of interfaces, the firewall assumes that the network is down and initiates a failover. Ping monitoring and session polling are not HA mechanisms, but they are used for path monitoring and session synchronization respectively. Reference: Palo Alto Networks Certified Software Firewall Engineer (PCSFE), [High Availability Overview], [Configure HA Link Monitoring], [Configure HA Path Monitoring], [Configure Session Synchronization]
NEW QUESTION # 35
Why are containers uniquely suitable for runtime security based on allow lists?
- A. Developers define the processes used in containers within the Dockerfile.
- B. Containers have only a few defined processes that should ever be executed.
- C. Operations teams know which processes are used within a container.
- D. Docker has a built-in runtime analysis capability to aid in allow listing.
Answer: B
Explanation:
Containers are uniquely suitable for runtime security based on allow lists because containers have only a few defined processes that should ever be executed. Developers can specify the processes that are allowed to run in a container using a Dockerfile, but this does not guarantee that only those processes will run at runtime. Therefore, using an allow list approach can prevent any unauthorized or malicious processes from running in a container2. Reference: Container Security
NEW QUESTION # 36
Which component can provide application-based segmentation and prevent lateral threat movement?
- A. NAT
- B. URL Filtering
- C. DNS Security
- D. App-ID
Answer: D
Explanation:
App-ID is the component that can provide application-based segmentation and prevent lateral threat movement. Application-based segmentation is a method of dividing the network into smaller segments or zones based on application or workload characteristics, such as function, dependency, owner, or security posture. Lateral threat movement is a technique used by attackers to move across the network from one compromised host to another, looking for sensitive data or assets. App-ID is a feature that identifies and classifies applications and protocols based on their content and characteristics, regardless of port, encryption, or evasion techniques. App-ID can provide application-based segmentation and prevent lateral threat movement by applying granular security policies based on application information to each segment or connection, blocking unauthorized access or data exfiltration. DNS Security, NAT, and URL Filtering are not components that can provide application-based segmentation and prevent lateral threat movement, but they are related features that can enhance security and visibility. Reference: Palo Alto Networks Certified Software Firewall Engineer (PCSFE), [App-ID Overview], [Microsegmentation with Palo Alto Networks], [Lateral Movement]

- A. Dynamic address group
- B. Content-ID
- C. External dynamic list
- D. App-ID
Answer: A
Explanation:
Dynamic address group is the component that allows the flexibility to add network resources but does not require making changes to existing policies and rules. Dynamic address group is an object that represents a group of IP addresses based on criteria such as tags, regions, interfaces, or user-defined attributes. Dynamic address group allows Security policies to adapt dynamically to changes in the network topology or workload characteristics without requiring manual updates. Content-ID, External dynamic list, and App-ID are not components that allow the flexibility to add network resources but do not require making changes to existing policies and rules, but they are related features that can enhance security and visibility.
