Question No. 1

Which offering can gain visibility and prevent an attack by a malicious actor attempting to exploit a known web server vulnerability using encrypted communication?

AOCSP

BSecure Sockets Layer (SSL) Inbound Inspection

CAdvanced URL Filtering (AURLF)

DWildFire

Show Answer

Correct Answer: B

Secure Sockets Layer (SSL) Inbound Inspection is the offering that can gain visibility and prevent an attack by a malicious actor attempting to exploit a known web server vulnerability using encrypted communication. SSL Inbound Inspection is a feature that allows the firewall to decrypt and inspect inbound SSL/TLS traffic from external clients to internal servers. SSL Inbound Inspection can gain visibility and prevent an attack by a malicious actor attempting to exploit a known web server vulnerability using encrypted communication 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. OCSP, Advanced URL Filtering (AURLF), and WildFire are not offerings that can gain visibility and prevent an attack by a malicious actor attempting to exploit a known web server vulnerability using encrypted communication, but they are related solutions that can enhance security and visibility.

Question No. 2

Which two statements apply to the VM-Series plugin? (Choose two.)

AIt can manage capabilities common to both VM-Series firewalls and hardware firewalls.

BIt can be upgraded independently of PAN-OS.

CIt enables management of cloud-specific interactions between VM-Series firewalls and supported public cloud platforms.

DIt can manage Panorama plugins.

Show Answer

Correct Answer: B, C

The two statements that apply to the VM-Series plugin are:

It can be upgraded independently of PAN-OS.

It enables management of cloud-specific interactions between VM-Series firewalls and supported public cloud platforms.

The VM-Series plugin is a software component that extends the functionality of the PAN-OS operating system to support cloud-specific features and APIs. The VM-Series plugin can be upgraded independently of PAN-OS to provide faster access to new cloud capabilities and integrations. The VM-Series plugin enables management of cloud-specific interactions between VM-Series firewalls and supported public cloud platforms, such as AWS, Azure, GCP, Alibaba Cloud, and Oracle Cloud. These interactions include bootstrapping, licensing, scaling, high availability, load balancing, and tagging. The VM-Series plugin cannot manage capabilities common to both VM-Series firewalls and hardware firewalls, as those are handled by PAN-OS. The VM-Series plugin cannot manage Panorama plugins, as those are separate software components that extend the functionality of the Panorama management server to support cloud-specific features and APIs.

Question No. 3

Which offering inspects encrypted outbound traffic?

AWildFire

BTLS decryption

CContent-ID

DAdvanced URL Filtering (AURLF)

Show Answer

Correct Answer: 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.

Question No. 4

Which component can provide application-based segmentation and prevent lateral threat movement?

ADNS Security

BNAT

CURL Filtering

DApp-ID

Show Answer

Correct Answer: D

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.

Question No. 5

Which two features of CN-Series firewalls protect east-west traffic between pods in different trust zones? (Choose two.)

AIntrusion prevention system

BCommunication with Panorama

CExternal load balancer

DLayer 7 visibility

Show Answer

Correct Answer: 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.
