PSE-SWFW-Pro-24 Exam Dumps : Palo Alto Networks Systems Engineer Professional - Software Firewall

Advanced CDSS subscriptions offer enhanced threat prevention capabilities:

A. To improve firewall throughput by inspecting hashes of advanced packet headers: While some security features use hashing, this is not the primary advantage of advanced CDSS.

B. To download and install new threat-related signature databases in real-time: Both standard and advanced CDSS subscriptions receive regular threat updates.

C. To use cloud-scale machine learning inline for detection of highly evasive and zero-day threats: This is a key differentiator of advanced CDSS. It leverages cloud-based machine learning to detect sophisticated threats that traditional signature-based methods might miss.

D. To use external dynamic lists for blocking known malicious threat sources and destinations: Both standard and advanced CDSS can use external dynamic lists.

Information about the specific features of advanced CDSS, such as inline machine learning, can be found on the Palo Alto Networks website and in datasheets comparing different CDSS subscription levels.

Comprehensive and Detailed In-Depth Step-by-Step Explanation:Palo Alto Networks uses a credit-based flexible licensing model (NGFW credits) for software firewalls, managed through deployment profiles in the Customer Support Portal. The Palo Alto Networks Systems Engineer Professional - Software Firewall documentation describes the characteristics of flex credit profiles within a credit pool.

Each VM-Series firewall deployment profile can be either fixed or flexible until defined and saved (Option A): In the Customer Support Portal, deployment profiles for VM-Series firewalls can start as undefined (neither fixed nor flexible) and are configured as either fixed (specific license allocation) or flexible (using NGFW credits) before saving. This flexibility allows customers to adjust profiles based on needs, a feature highlighted in the documentation for managing software firewalls efficiently.

Allocate credits for use with Cloud NGFW for AWS and Azure (Option D): NGFW credits from a credit pool can be allocated to deploy and manage Cloud NGFW instances in AWS and Azure, in addition to VM-Series and CN-Series. The documentation notes that flex credit profiles enable customers to dynamically allocate credits across different firewall types, including cloud-native firewalls, ensuring scalability and cost efficiency in public cloud environments.

Options B (All firewalls activated to a deployment profile will have the same subscriptions) and C (The number of licensed cores must match the number of provisioned CPU cores per instance) are incorrect. Firewalls in a deployment profile can have different subscriptions based on specific needs, not necessarily the same, making Option B inaccurate. For flexible licensing, the number of licensed cores (vCPUs) does not need to match provisioned CPU cores exactly; licensing tiers are based on performance levels (e.g., Tier 1, Tier 2), not a one-to-one match, so Option C is not a characteristic of flex credit profiles.

Palo Alto Networks provides various reference architectures for deploying VM-Series firewalls in different cloud environments. Let's examine the options:

A. Cloud NGFW for AWS: Combined Model: While Cloud NGFW is an offering, the term "Combined Model" isn't a standard, documented reference architecture name. Cloud NGFW for AWS focuses on simplified deployment and management but doesn't use this specific terminology for its deployment models.

B. AWS VM-Series: Isolated Transit Gateway: This is a VALID deployment model. It involves deploying VM-Series firewalls in an isolated VPC connected to AWS Transit Gateway. This provides centralized security inspection for traffic flowing between different VPCs and on-premises networks connected to the Transit Gateway.
