PSE-Strata-Pro-24 Exam Dumps : Palo Alto Networks Systems Engineer Professional - Hardware Firewall

To address the MSSP’s requirement for logically separated BGP peering setups while efficiently managing standard routing rules and updates, Palo Alto Networks offers the Advanced Routing Engine introduced in PAN-OS 11.0. The Advanced Routing Engine enhances routing capabilities, including support for logical routers, which is critical in this scenario.

Why A is Correct

Logical routers enable the MSSP to create isolated BGP peering configurations for each customer.

The Advanced Routing Engine allows the MSSP to share standard routing profiles (such as filters, policies, or maps) across logical routers, simplifying the deployment and maintenance of routing configurations.

This approach ensures scalability, as each logical router can handle the unique needs of a customer while leveraging shared routing rules.

Why Other Options Are Incorrect

B: While using APIs to automate deployment is beneficial, it does not solve the need for logically separated BGP peering setups. Logical routers provide this separation natively.

C: While virtual routers in PAN-OS can separate BGP peering setups, they do not support the efficient sharing of standard routing rules and profiles across multiple routers.

D: Virtual systems (vsys) are used to segregate administrative domains, not routing configurations. Vsys is not the appropriate solution for managing BGP peering setups across multiple customers.

Key Takeaways:

PAN-OS Advanced Routing Engine with logical routers simplifies BGP peering management for MSSPs.

Logical routers provide the separation required for customer environments while enabling shared configuration profiles.

A perimeter firewall is traditionally deployed at the boundary of a network to protect it from external threats. It provides a variety of protections, including blocking unauthorized access, inspecting traffic flows, and safeguarding sensitive resources. Here is how the options apply:

Option A (Correct): Perimeter firewalls provide network layer protection by filtering and inspecting traffic entering or leaving the network at the outer edge. This is one of their primary roles.

Option B: Power utilization is not a functional or architectural aspect of a firewall and is irrelevant when describing the purpose of a perimeter firewall.

Option C: Securing east-west traffic is more aligned with data center firewalls, which monitor lateral (east-west) movement of traffic within a virtualized or segmented environment. A perimeter firewall focuses on north-south traffic instead.

Option D (Correct): A perimeter firewall primarily secures north-south traffic, which refers to traffic entering and leaving the network. It ensures that inbound and outbound traffic adheres to security policies.

Option E (Correct): Perimeter firewalls play a critical role in guarding against external attacks, such as DDoS attacks, malicious IP traffic, and other unauthorized access attempts.

When configuring Advanced URL Filtering on a Palo Alto Networks firewall, the "Ransomware" category should be explicitly blocked to protect customers from URLs associated with ransomware activities. Ransomware URLs typically host malicious code or scripts designed to encrypt user data and demand a ransom. By blocking the "Ransomware" category, systems engineers can proactively prevent users from accessing such URLs.

Why "Ransomware" (Correct Answer A)?The "Ransomware" category is specifically curated by Palo Alto Networks to include URLs known to deliver ransomware or support ransomware operations. Blocking this category ensures that any URL categorized as part of this list will be inaccessible to end-users, significantly reducing the risk of ransomware attacks.

Why not "High Risk" (Option B)?While the "High Risk" category includes potentially malicious sites, it is broader and less targeted. It may not always block ransomware-specific URLs. "High Risk" includes a range of websites that are flagged based on factors like bad reputation or hosting malicious content in general. It is less focused than the "Ransomware" category.

Why not "Scanning Activity" (Option C)?The "Scanning Activity" category focuses on URLs used in vulnerability scans, automated probing, or reconnaissance by attackers. Although such activity could be a precursor to ransomware attacks, it does not directly block ransomware URLs.

Why not "Command and Control" (Option D)?The "Command and Control" category is designed to block URLs used by malware or compromised systems to communicate with their operators. While some ransomware may utilize command-and-control (C2) servers, blocking C2 URLs alone does not directly target ransomware URLs themselves.

By using the Advanced URL Filtering profile and blocking the "Ransomware" category, the firewall applies targeted controls to mitigate ransomware-specific threats.
