NEW QUESTION # 55
Which technique is an example of a DNS attack that Advanced DNS Security can detect and prevent?

A. Polymorphic DNS
B. High entropy DNS domains
C. CNAME cloaking
D. DNS domain rebranding

Answer: B

Explanation:
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.

NEW QUESTION # 56
A customer has acquired 10 new branch offices, each with fewer than 50 users and no existing firewall.
The systems engineer wants to recommend a PA-Series NGFW with Advanced Threat Prevention at each branch location. Which NGFW series is the most cost-efficient at securing internet traffic?

A. PA-500
B. PA-400
C. PA-600
D. PA-200

Answer: B

Explanation:
ThePA-400 Seriesis the most cost-efficient Palo Alto Networks NGFW for small branch offices. Let's analyze the options:
PA-400 Series (Recommended Option)
* The PA-400 Series (PA-410, PA-415, etc.) is specifically designed for small to medium-sized branch offices with fewer than 50 users.
* It provides all the necessary security features, including Advanced Threat Prevention, at a lower price point compared to higher-tier models.
* It supports PAN-OS and Cloud-Delivered Security Services (CDSS), making it suitable for securing internet traffic at branch locations.
Why Other Options Are Incorrect
* PA-200:The PA-200 is an older model and is no longer available. It lacks the performanceand features needed for modern branch office security.
* PA-500:The PA-500 is also an older model that is not as cost-efficient as the PA-400 Series.
* PA-600:The PA-600 Series does not exist.
Key Takeaways:
* For branch offices with fewer than 50 users, the PA-400 Series offers the best balance of cost and performance.

NEW QUESTION # 57
A customer asks a systems engineer (SE) how Palo Alto Networks can claim it does not lose throughput performance as more Cloud-Delivered Security Services (CDSS) subscriptions are enabled on the firewall.
Which two concepts should the SE explain to address the customer's concern? (Choose two.)

A. Single Pass Architecture
B. Management Data Plane Separation
C. Parallel Processing
D. Advanced Routing Engine

Answer: A,C

Explanation:
The customer's question focuses on how Palo Alto Networks Strata Hardware Firewalls maintain throughput performance as more Cloud-Delivered Security Services (CDSS) subscriptions-such as Threat Prevention, URL Filtering, WildFire, DNS Security, and others-are enabled. Unlike traditional firewalls where enabling additional security features often degrades performance, Palo Alto Networks leverages its unique architecture to minimize this impact. The systems engineer (SE) should explain two key concepts-Parallel Processing and Single Pass Architecture-which are foundational to the firewall's ability to sustain throughput. Below is a detailed explanation, verified against Palo Alto Networks documentation.
Step 1: Understanding Cloud-Delivered Security Services (CDSS) and Performance Concerns CDSS subscriptions enhance the Strata Hardware Firewall's capabilities by integrating cloud-based threat intelligence and advanced security features into PAN-OS. Examples include:
* Threat Prevention: Blocks exploits, malware, and command-and-control traffic.
* WildFire: Analyzes unknown files in the cloud for malware detection.
* URL Filtering: Categorizes and controls web traffic.
Traditionally, enabling such services on other firewalls increases processing overhead, as each feature requires separate packet scans or additional hardware resources, leading to latency and throughput loss. Palo Alto Networks claims consistent performance due to its innovative design, rooted in the Single Pass Parallel Processing (SP3) architecture.
Reference: Palo Alto Networks Cloud-Delivered Security Services Overview
"CDSS subscriptions integrate with NGFWs to deliver prevention-oriented security without compromising performance, leveraging the SP3 architecture." Step 2: Explaining the Relevant Concepts The SE should focus on A. Parallel Processing and C. Single Pass Architecture, as these directly address how throughput is maintained when CDSS subscriptions are enabled.
Concept A: Parallel Processing
Definition: Parallel Processing refers to the hardware architecture in Palo Alto Networks NGFWs, where specialized processors handle distinct functions (e.g., networking, security, decryption) simultaneously. This is achieved through a separation of duties across dedicated hardware components, such as the Network Processor, Security Processor, and Signature Matching Processor, all working in parallel.
How It Addresses the Concern: When CDSS subscriptions are enabled, tasks like threat signature matching (Threat Prevention), URL categorization (URL Filtering), or file analysis forwarding (WildFire) are offloaded to specific processors. These operate concurrently rather than sequentially, preventing bottlenecks. The parallel execution ensures that adding more security services doesn't linearly increase processing time or reduce throughput.
Technical Detail:
Network Processor: Handles routing, NAT, and flow lookup.
Security Processor: Manages encryption/decryption and policy enforcement.
Signature Matching Processor: Performs content inspection for threats and CDSS features.
High-speed buses (e.g., 1Gbps in high-end models) connect these processors, enabling rapid data transfer.
Outcome: Throughput remains high because the workload is distributed across parallel hardware resources, not stacked on a single CPU.
Reference: PAN-OS Administrator's Guide (11.1) - Hardware Architecture
"Parallel Processing hardware ensures that function-specific tasks are executed concurrently, maintaining performance as security services scale." Concept C: Single Pass Architecture Definition: Single Pass Architecture is the software approach in PAN-OS where a packet is processed once, with all necessary functions-networking, policy lookup, App-ID, User-ID, decryption, and content inspection (including CDSS features)-performed in a single pass. This contrasts with multi-pass architectures, where packets are scanned repeatedly for each enabled feature.
How It Addresses the Concern: When CDSS subscriptions are activated, their inspection tasks (e.g., threat signatures, URL checks) are integrated into the single-pass process. The packet isn't reprocessed for each service; instead, a stream-based, uniform signature-matching engine applies all relevant checks in one go.
This minimizes latency and preserves throughput, as the overhead of additional services is marginal.
Technical Detail:
A packet enters the firewall and is classified by App-ID.
Decryption (if needed) occurs, exposing content.
A single Content-ID engine scans the stream for threats, URLs, and other CDSS-related patterns simultaneously.
Policy enforcement and logging occur without additional passes.
Outcome: Enabling more CDSS subscriptions adds rules to the existing scan, not new processing cycles, ensuring consistent performance.
Reference: Palo Alto Networks Single Pass Architecture Whitepaper
"Single Pass software performs all security functions in one pass, eliminating redundant processing and maintaining high throughput even with multiple services enabled." Step 3: Evaluating the Other Options To confirm A and C are correct, let's examine why B and D don't directly address the throughput concern:
B). Advanced Routing Engine:
Analysis: The Advanced Routing Engine in PAN-OS enhances routing capabilities (e.g., BGP, OSPF) and supports features like path monitoring. While important for network performance, it doesn't directly influence the processing of CDSS subscriptions, which occur at the security and content inspection layers, not the routing layer.
Conclusion: Not relevant to the question.
Reference: PAN-OS Administrator's Guide (11.1) - Routing Overview - "The Advanced Routing Engine optimizes network paths but is separate from security processing." D). Management Data Plane Separation:
Analysis: This refers to the separation of the control plane (management tasks like configuration and logging) and data plane (packet processing). It ensures management tasks don't impact traffic processing but doesn't directly address how CDSS subscriptions affect throughput within the data plane itself.
Conclusion: Indirectly supportive but not a primary explanation.
Reference: PAN-OS Administrator's Guide (11.1) - Hardware Architecture - "Control and data plane separation prevents management load from affecting throughput." Step 4: Tying It Together for the Customer The SE should explain:
Parallel Processing: "Our firewalls use dedicated hardware processors working in parallel for networking, security, and threat inspection. When you enable more CDSS subscriptions, the workload is spread across these processors, so throughput doesn't drop." Single Pass Architecture: "Our software processes each packet once, applying all security checks-including CDSS features-in a single scan. This avoids the performance hit you'd see with other firewalls that reprocess packets for each new service." This dual approach-hardware parallelism and software efficiency-ensures the firewall scales security without sacrificing speed.
