Pearson PCNSE New Attempt

The engineer is configuring a DoS Protection profile to defend specific endpoints and resources against malicious activity. A DoS Protection profile is a feature that enables the firewall to detect and prevent denial-of-service (DoS) attacks that attempt to overwhelm network resources or disrupt services. A DoS Protection profile can provide granular defense against targeted flood attacks for specific critical systems that are accessed by users from the internet, such as web servers, DNS servers, or VPN gateways. A DoS Protection profile can be applied to a security policy rule that matches the traffic to and from the protected systems, and can specify the thresholds and actions for different types of flood attacks, such as SYN, UDP, ICMP, or other IP floods12. References: DoS Protection, PCNSE Study Guide (page 58)

In Palo Alto Networks firewalls, the order of rule evaluation is critical for traffic enforcement. To ensure high priority evaluation, rules should be configured at the top of the rulebase so they are matched before others. The Security Pre-Rules are designed for shared policies across multiple device groups in Panorama, and by placing the block action rules at the top of the Pre-Rules, it guarantees that these rules are evaluated first, before any device-specific or post-rules.For verification, please refer to the Palo Alto Networks "PAN-OS® Administrator’s Guide" or the official configuration documentation for Panorama and device group rules.

D is the correct answer because the threat log type would provide information about traffic blocked by a Zone Protection profile. This is because Zone Protection profiles are used to protect the network from attacks, including common flood, reconnaissance attacks, and other packet-based attacks1. These attacks are classified as threats by the firewall and are logged in the threat log2. The threat log displays information such as the source and destination IP addresses, ports, zones, applications, threat types, actions, and severity of the threats2.
