Paloalto Networks PSE-Strata-Pro-24 Exam With Confidence Using Practice Dumps

The customer is seeking centralized policy management to reduce human error while maintaining compliance with their contractual obligations to AWS and Azure. Here's the evaluation of each option:

Option A: Cloud NGFWs at both CSPs; provide the customer a license for a Panorama virtual appliance from their CSP's marketplace of choice to centrally manage the systems

Cloud NGFW is a fully managed Next-Generation Firewall service by Palo Alto Networks, offered in AWS and Azure marketplaces. It integrates natively with the CSP infrastructure, making it a good fit for customers with existing CSP agreements.

Panorama, Palo Alto Networks' centralized management solution, can be deployed as a virtual appliance in the CSP marketplace of choice, enabling centralized policy management across all NGFWs.

This option addresses the customer's need for centralized management while leveraging their existing contracts with AWS and Azure.

This option is appropriate.

Option B: Cloud NGFWs in AWS and VM-Series firewall in Azure; the customer selects a PAYG licensing Panorama deployment in their CSP of choice

This option suggests using Cloud NGFW in AWS but VM-Series firewalls in Azure. While VM-Series is a flexible virtual firewall solution, it may not align with the customer’s stated preference for CSP-managed services like Cloud NGFW.

This option introduces a mix of solutions that could complicate centralized management and reduce operational efficiency.

This option is less appropriate.

Option C: VM-Series firewalls in both CSPs; manually built Panorama in the CSP of choice on a host of either type: Palo Alto Networks provides a license

VM-Series firewalls are well-suited for cloud deployments but require more manual configuration compared to Cloud NGFW.

Building a Panorama instance manually on a host increases operational overhead and does not leverage the customer’s existing CSP marketplaces.

This option is less aligned with the customer's needs.

Option D: VM-Series firewall and CN-Series firewall in both CSPs; provide the customer a private-offer Panorama virtual appliance from their CSP’s marketplace of choice to centrally manage the systems

This option introduces both VM-Series and CN-Series firewalls in both CSPs. While CN-Series firewalls are designed for Kubernetes environments, they may not be relevant if the customer does not specifically require container-level security.

Adding CN-Series firewalls may introduce unnecessary complexity and costs.

This option is not appropriate.

When planning a firewall deployment with SSL/TLS decryption enabled, it is crucial to consider the additional processing overhead introduced by decrypting and inspecting encrypted traffic. Here are the details for each statement:

Why "SSL decryption traffic amounts vary from network to network" (Correct Answer A)?SSL decryption traffic varies depending on the organization’s specific network environment, user behavior, and applications. For example, networks with heavy web traffic, cloud applications, or encrypted VoIP traffic will have more SSL/TLS decryption processing requirements. This variability means each deployment must be properly assessed and sized accordingly.

Why "Perfect Forward Secrecy (PFS) ephemeral key exchange algorithms such as Diffie-Hellman Ephemeral (DHE) and Elliptic-Curve Diffie-Hellman Exchange (ECDHE) consume more processing resources than Rivest-Shamir-Adleman (RSA) algorithms" (Correct Answer C)?PFS algorithms like DHE and ECDHE generate unique session keys for each connection, ensuring better security but requiring significantly more processing power compared to RSA key exchange. When decryption is enabled, firewalls must handle these computationally expensive operations for every encrypted session, impacting performance and sizing requirements.

Why not "Large average transaction sizes consume more processing power to decrypt" (Option B)?While large transaction sizes can consume additional resources, SSL/TLS decryption is more dependent on the number of sessions and the complexity of the encryption algorithms used, rather than the size of the transactions. Hence, this is not a primary best practice consideration.

Why not "Rivest-Shamir-Adleman (RSA) certificate authentication method consumes more resources than Elliptic Curve Digital Signature Algorithm (ECDSA), but ECDSA is more secure" (Option D)?This statement discusses certificate authentication methods, not SSL/TLS decryption performance. While ECDSA is more efficient and secure than RSA, it is not directly relevant to sizing considerations for firewall deployments with decryption enabled.

Advanced DNS Security on Palo Alto Networks firewalls is designed to identify and prevent a wide range of DNS-based attacks. Among the listed options, "High entropy DNS domains" is a specific example of a DNS attack that Advanced DNS Security can detect and block.

Why "High entropy DNS domains" (Correct Answer A)?High entropy DNS domains are often used in attacks where randomly generated domain names (e.g., gfh34ksdu.com) are utilized by malware or bots to evade detection. This is a hallmark of Domain Generation Algorithms (DGA)-based attacks. Palo Alto Networks firewalls with Advanced DNS Security use machine learning to detect such domains by analyzing the entropy (randomness) of DNS queries. High entropy values indicate the likelihood of a dynamically generated or malicious domain.

Why not "Polymorphic DNS" (Option B)?While polymorphic DNS refers to techniques that dynamically change DNS records to avoid detection, it is not specifically identified as an attack type mitigated by Advanced DNS Security in Palo Alto Networks documentation. The firewall focuses more on the behavior of DNS queries, such as detecting DGA domains or anomalous DNS traffic patterns.

Why not "CNAME cloaking" (Option C)?CNAME cloaking involves using CNAME records to redirect DNS queries to malicious or hidden domains. Although Palo Alto firewalls may detect and block malicious DNS redirections, the focus of Advanced DNS Security is primarily on identifying patterns of DNS abuse like DGA domains, tunneling, or high entropy queries.

Why not "DNS domain rebranding" (Option D)?DNS domain rebranding involves changing the domain names associated with malicious activity to evade detection. This is typically a tactic used for persistence but is not an example of a DNS attack type specifically addressed by Advanced DNS Security.

Advanced DNS Security focuses on dynamic, real-time identification of suspicious DNS patterns, such as high entropy domains, DNS tunneling, or protocol violations. High entropy DNS domains are directly tied to attack mechanisms like DGAs, making this the correct answer.
