최신 Palo Alto Networks Certification NetSec-Analyst 무료샘플문제 (Q178-Q183):

질문 # 178
A network security analyst is investigating erratic packet forwarding behavior on a Palo Alto Networks firewall running advanced threat prevention services. Some legitimate traffic flows are experiencing severe latency or being dropped, while others are processed normally. The firewall's data plane CPU utilization is consistently low, and traffic logs show no explicit denies, but session end reasons indicate 'aged-out' or 'session-limit'. A 'debug dataplane packet-diag' output for an affected flow shows the packet reaching the 'flow_lookup' stage but then appears to get stuck or re-evaluated endlessly without being forwarded. Which of the following is the most obscure and difficult to diagnose misconfiguration or state that could cause this behavior?

• A. An excessive number of active sessions, hitting the firewall's session limit per flow or per security zone, causing new legitimate sessions to be dropped.
• B. The firewall's Content-ID engine is stuck in a pattern matching loop due to a malicious or malformed payload, consuming excessive resources for specific flows.
• C. A subtle misconfiguration in a 'policy-based fomarding' rule, where an implicit 'any' match condition is inadvertently matching and forwarding traffic to an incorrect or non-existent next-hop, leading to blackholing or routing loops.
• D. A misconfigured custom application signature (App-ID) is causing a continuous re-evaluation loop, preventing the session from establishing or being correctly identified.
• E. A fragmented packet reassembly issue, where out-of-order or missing fragments are preventing the firewall from correctly identifying the application or threat, leading to session aging/timeout.

정답：D

설명：
The key here is 'packet reaching the 'flow_lookup' stage but then appears to get stuck or re-evaluated endlessly without being forwarded.' This symptom, combined with 'aged-out' or 'session-limit' without explicit denies and low data plane CPU, strongly points to an issue with how the firewall is classifying the session at the very early stages. A misconfigured custom App-ID signature (A) can create a scenario where the firewall keeps re-evaluating the flow against a complex or faulty pattern, never successfully classifying it. This prevents the session from moving past the initial lookup phase, leading to timeouts Caged-out') or hitting internal session limits if multiple re-evaluations create new ephemeral internal 'sessions'. Options B, C, D are common but usually have different diagnostic indicators (high resource usage, explicit drops, or different session end reasons). Option E would typically manifest as routing issues or blackholing but wouldn't typically cause the 'stuck at flow_lookup' symptom unless it somehow triggered a continuous re-evaluation of the flow table. A faulty custom App-ID is notoriously difficult to debug as it resides deep within the packet processing pipeline.

 

질문 # 179
A Palo Alto Networks firewall is configured with an Anti-Spyware profile that includes a custom signature designed to detect a specific command-and-control (C2) beacon. The signature is defined with a 'Context' of 'Server' and a 'Direction' of 'C2'. During a security incident investigation, you observe traffic from an internal compromised host initiating an outbound connection to a known C2 server, but the custom signature is not triggering. Which of the following could be potential reasons for the signature not triggering, assuming the C2 beacon itself matches the signature's pattern?

• A. The Anti-Spyware profile is not applied to the security policy allowing the outbound traffic.
• B. The C2 server is using a non-standard port, and the firewall's application identification (App-ID) is incorrectly identifying the application.
• C. The custom signature's 'Context' is 'Server', but the compromised host is acting as a 'Client' in the C2 connection.
• D. The custom signature's 'Direction' is 'C2', but the C2 traffic is flowing from the C2 server to the compromised host.
• E. The traffic is encrypted, and SSL decryption is not enabled or failing for this traffic.

정답：A,C,E

설명：
This is a multiple-response question. Let's analyze each option: A. The traffic is encrypted, and SSL decryption is not enabled or failing for this traffic. If the C2 beacon is within encrypted traffic, and SSL decryption isn't in place, the firewall cannot inspect the payload, thus the signature won't trigger. This is a very common reason for signatures to fail. B. The Anti-Spyware profile is not applied to the security policy allowing the outbound traffic. Security profiles, including Anti-Spyware, must be explicitly attached to security policies for them to be enforced. If it's missing, the signature won't be evaluated. C. The custom signature's 'Context' is 'Server', but the compromised host is acting as a 'Client' in the C2 connection. Custom signatures can be context-sensitive (Client, Server, or Both). If the signature is defined with 'Server' context, it will only inspect patterns from the server's side of the conversation. If the compromised host is initiating the C2 connection (acting as the client) and sending the beacon, a 'Server' context signature won't detect it. This is a common misconfiguration. D. The custom signature's 'Direction' is 'C2', but the C2 traffic is flowing from the C2 server to the compromised host. The 'Direction' of 'C2' means Command and Control, which typically refers to traffic initiated by the compromised host (client) to the C2 server. If the signature is for outbound C2, and the traffic observed is inbound, it might not match depending on the exact signature logic, but more critically, 'C2' direction implies outbound. The 'Client' vs. 'Server' context is usually more impactful here. E. The C2 server is using a non-standard port, and the firewall's application identification (App-ID) is incorrectly identifying the application. While App-ID can affect policy enforcement, custom signatures operate at a deeper level and can inspect traffic regardless of App-ID if the relevant security profile is applied. The signature is designed to match a pattern, not rely solely on App-ID for its detection logic. Incorrect App-ID might affect policy application, but not necessarily the signature's ability to match the byte pattern itself if the security profile is applied to the 'any' application or the correct identified application.

 

질문 # 180
A large enterprise is deploying SD-WAN across 100+ branch offices using Panorama'. Each branch has a primary internet link and a secondary LTE link. The requirement is for all mission-critical applications (e.g., SAP, Salesforce) to exclusively use the primary internet link if its path quality (latency, jitter, packet loss) meets a predefined SLA. If the primary link degrades, these applications should automatically failover to the LTE link. Non-critical traffic should be load-balanced across both links. Which SD-WAN configuration elements are MOST crucial to implement this design efficiently and scalably from Panorama, assuming consistent policy across branches?

• A. A single SD-WAN profile applied to a template stack, containing two SD-WAN policy rules: one for mission-critical apps with a 'Performance-Based' path selection referencing a 'High_SLA_ProfiIe' and prioritizing the primary link, and another rule for non-critical apps with 'Session Distribution' load balancing.
• B. Separate SD-WAN profiles for each application type (critical and non-critical), each assigned to specific virtual routers. The critical application profile would use 'Best Quality' path selection, and the non-critical would use 'Weighted Round Robin'.
• C. Create a 'PBP (Policy Based Forwarding) rule for critical applications to force them over the primary interface, and a second PBF rule for non-critical traffic to load balance across interfaces. Use an 'SLA Monitoring' profile to trigger the PBF rules.
• D. Define two 'Path Monitoring' profiles: one for the primary link with strict SLA thresholds, and another for the LTE link with looser thresholds. Then, create two SD-WAN policy rules per application (critical/non-critical) that reference these path monitoring profiles directly.
• E. Utilize 'Service Routes' to statically route critical applications over the primary link and non-critical over the LTE, then apply 'BGP Conditional Advertisements' to handle failover based on link health.

정답：A

설명：
Option A is the most efficient and scalable solution. A single SD-WAN profile within a template stack ensures consistency across all 100+ branches. Defining two specific SD-WAN policy rules within this profile one for mission-critical apps using 'Performance-Based' path selection with an SLA profile and explicit primary link preference, and another for non-critical apps using 'Session Distribution' directly addresses all requirements. This leverages the core strengths of SD-WAN profiles for dynamic path selection and application-aware routing. Option B introduces unnecessary complexity with separate profiles per application type and virtual routers. Option C incorrectly suggests two path monitoring profiles per link; path monitoring applies to links, and performance profiles are then applied to applications. Option D and E describe traditional routing or PBF mechanisms which are less dynamic and scalable than native SD-WAN for this specific use case.

 

질문 # 181
A Palo Alto Networks firewall is configured with an External Dynamic List of type 'URL' for blocking known malicious URLs. The list is extensive, containing millions of entries. The security team notices a significant increase in firewall management plane CPU utilization and occasional delays in policy commit operations after implementing this large EDL. Which two adjustments or considerations are most critical to mitigate these performance impacts without compromising security efficacy?

• A. Ensure the EDL source server is highly available and responsive to minimize timeout errors.
• B. Split the single large EDL into multiple smaller EDLs based on threat categories or geography.
• C. Consider upgrading the firewall model to one with higher management plane resources and more memory.
• D. Reduce the EDL's 'Repeat' refresh interval to a longer duration (e.g., from hourly to daily).
• E. Utilize a dedicated log collector or Panorama appliance to offload EDL processing.

정답：C,D

설명：
Handling extremely large EDLs can significantly impact firewall performance, especially the management plane. Option A (Correct): Reducing the refresh frequency is a primary mitigation. Each refresh involves downloading, parsing, and committing the EDL entries, which are CPU-intensive operations on the management plane. Fewer refreshes mean less overhead. Option E (Correct): For 'millions of entries,' the current firewall model might simply be undersized. Larger EDLs consume more memory and require more CPU cycles for processing and lookup, directly impacting management plane performance. Upgrading to a model with more resources is a direct solution. Option B is important for successful updates, but it doesn't directly address the firewall's internal processing burden once the file is downloaded. Option C might help organize but doesn't fundamentally reduce the total number of entries the firewall has to process or store. The aggregate impact remains. Option D (log collector/Panorama) is for log processing and centralized management; it does not offload the firewall's internal EDL processing.

 

질문 # 182
A large enterprise with a global presence is deploying Palo Alto Networks firewalls across hundreds of branch offices. The security team needs to ensure consistent security policies, network configurations, and software versions across all devices, while also allowing localized administrative control for specific regions without compromising central oversight. They are currently struggling with policy sprawl and inconsistent configurations due to a lack of a standardized management approach.

• A. Implement Panorama as a centralized management system, utilizing Device Groups to logically organize firewalls and manage shared policies. Then, use Administrative Roles to delegate granular access based on regions.
• B. Use a third-party SIEM solution to monitor firewall configurations and manually correct any discrepancies.
• C. Manage each firewall individually via its web interface and create custom policy sets for each branch based on regional requirements.
• D. Deploy a single, monolithic firewall and route all branch traffic through it to simplify policy management.
• E. Utilize an Ansible playbook to push configurations to all firewalls, relying solely on automation for consistency.

정답：A

설명：
Option A is the most effective solution. Panorama provides centralized management, enabling consistent policy deployment through Device Groups and shared policy objects. Administrative Roles allow for the delegation of specific management tasks and access rights to regional administrators without giving them full control, thus maintaining central oversight while enabling localized administration. Options B, C, D, and E do not address the core challenges of scalability, consistency, and controlled delegation in a large enterprise environment.
