Palo Alto Networks Network Security Analyst Sample Questions (Q103-Q108):

NEW QUESTION # 103
A critical server application relies on a set of custom web services running on non-standard ports. The security team needs to ensure that these specific web services are protected by comprehensive threat prevention, including WildFire analysis, but without impacting the performance of other high-volume, less critical HTTP/S traffic. The firewall must distinguish between these custom services and standard HTTP/S. Which approach offers the most efficient and secure configuration?

A. Configure the existing 'web-browsing' application to include the custom non-standard ports within the service object. Create a security policy rule for this modified 'web-browsing' application, allowing it to the critical server. Apply a comprehensive Security Profile Group (with WildFire) to this rule, and then create a separate, less restrictive policy for general HTTP/S traffic.
B. Create a custom application for each specific web service using a signature-based approach or by specifying the application name (e.g., 'web-browsing') with custom ports. Then, create a single security policy rule for all web traffic (HTTP/S and custom services), and apply a comprehensive Security Profile Group (including WildFire) to this rule.
C. Utilize policy-based forwarding (PBF) to direct all traffic destined for the critical server through a dedicated Vwire interface. On this Vwire, apply a zone protection profile and a comprehensive Security Profile Group including WildFire. For other HTTP/S traffic, apply standard security policies.
D. Create a service object for each custom port. Define a security policy rule allowing these service objects to the critical server. Apply a Security Profile Group containing Antivirus, Anti-Spyware, Vulnerability Protection, and a WildFire Analysis profile. For standard HTTP/S traffic, apply a separate security policy with a less CPU-intensive Security Profile Group.
E. Define a custom application for each non-standard web service, explicitly identifying its port and application type. Create a dedicated security policy rule for these custom applications, allowing traffic from relevant sources to the critical server. To this rule, attach a Security Profile Group containing Antivirus, Anti-Spyware, Vulnerability Protection, URL Filtering (tuned for web services), File Blocking, and a WildFire Analysis profile configured for all file types.

Answer: E

Explanation:
Option B is the most efficient and secure approach. By defining custom applications for the non-standard web services, the firewall can accurately identify and classify this specific traffic, even on non-standard ports. This allows for the creation of a dedicated security policy rule with granular source/destination/user matching. Applying a comprehensive Security Profile Group (including WildFire) to this specific rule ensures that only the critical web services receive intensive inspection, without impacting general HTTP/S traffic. This granular application of profiles is key to balancing security and performance. Option A is inefficient as it applies comprehensive inspection to all web traffic. Option C modifies a built-in app, which is generally not recommended for such specific requirements and can lead to unintended consequences. Option D involves network topology changes (PBF, Vwire) which are unnecessary for this security profile requirement. Option E uses service objects but doesn't leverage App-ID's ability to classify the application itself, leading to less accurate and potentially less secure identification.

NEW QUESTION # 104
An analyst is investigating why an App-ID for a custom application is showing as "unknown-tcp" in the Traffic logs. The application is running on port 8080. What is the most likely cause of this identification failure?

A. The Security policy is set to "application-default."
B. The URL category is "private-ip-addresses."
C. The firewall does not have a signature for the proprietary application.
D. The traffic is being decrypted by an SSL Forward Proxy.

Answer: C

Explanation:
When traffic is logged as unknown-tcp or unknown-udp, it indicates that the App-ID engine has inspected the traffic but could not find a matching signature in its database. For proprietary or internal applications, this is the expected behavior unless the analyst has created a Custom Application Signature.
To resolve this, the analyst must capture the packet flow and identify a unique data pattern (signature) within the payload that identifies the application. Once the custom App-ID is created and committed, the firewall will correctly categorize the traffic, allowing the analyst to apply granular security profiles and reporting. Identifying and remediating "unknown" traffic is a key monitoring objective, as it helps eliminate visibility gaps and prevents malicious traffic from
"hiding" behind unidentified protocols.

NEW QUESTION # 105
Which security profile is specifically designed to protect against "Domain Generation Algorithms" (DGA) and DNS tunneling?

A. Anti-Spyware Profile
B. URL Filtering Profile
C. DNS Security Profile
D. Vulnerability Protection Profile

Answer: C

Explanation:
The DNS Security Profile (often part of the Advanced Threat Prevention subscription) is the specialized engine for detecting sophisticated DNS-based attacks. Unlike traditional static lists, it uses real-time, cloud-based AI and machine learning to identify DGA domains and DNS tunneling attempts used by malware for Command and Control (C2).
By attaching this profile to a security rule, the firewall can intercept DNS queries and perform an
"inline" check against the DNS Security cloud. If a query is identified as part of a tunneling attempt or a malicious DGA-generated domain, the firewall can sinkhole the request or block it immediately. This is a critical objective for an analyst, as DNS is a frequently overlooked vector that attackers use to bypass traditional perimeter security. Implementing DNS Security ensures that the organization is protected against modern, evasive threats that rely on the foundational protocols of the internet.

NEW QUESTION # 106
What is the most granular method for ensuring that traffic to a firewall's public IP address on the public interface is translated to the private IP address of the web server?

A. Create one NAT policy, set the source address to the public IP address and destination address to the private IP address, and ensure Bi-directional is checked.
B. Create two static NAT policies, ensure one policy has original packet destination IP as the public IP address and translated packet destination IP as the private IP address, ensure the other policy has original packet source IP as the private IP address and the translated packet source IP as the public IP address.
C. Create one NAT policy, ensure the policy has original packet source IP as the private IP address and the translated packet source IP as the public IP address, and mark Bi-directional as "Yes."
D. Create one NAT policy, ensure the policy has original packet destination IP as the public IP address and translated packet destination IP as the private IP address, and mark Bi-directional as "Yes."

Answer: C

Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From Palo Alto Networks Network Security Analyst Knowledge:
In Palo Alto Networks PAN-OS, the most efficient and granular way to configure a 1-to-1 static NAT (Network Address Translation) for a server-such as a web server-is to use a Bi-directional NAT statement. The specific logic required by the firewall is to define the rule from the perspective of the outbound traffic (Source NAT) while enabling the "Bi-directional" checkbox.
When you create a NAT policy where the Original Packet source is the private IP address of the web server and the Translated Packet source is the public IP address, checking the Bi-directional box causes the firewall to automatically create an implicit "twin" rule. This hidden rule handles the inbound (Destination NAT) traffic, mapping the public IP back to the private IP for incoming requests.
Option D is correct because it correctly identifies the required "Original Source" as the private IP. Option A is incorrect because Bi-directional NAT cannot be enabled on a rule where the translation type is Destination NAT. Option C is technically functional but is not the most "granular" or efficient method, as it requires manual management of two separate rules, increasing the risk of configuration drift. By using the Bi- directional setting on the source-based rule, the analyst ensures that the server can both initiate outbound connections (like updates) and receive inbound traffic (like web requests) using a single, consistent mapping.

NEW QUESTION # 107
How is the hit count reset on a rule?

A. select a security policy rule, right click Hit Count > Reset
B. Device > Setup > Logging and Reporting Settings > Reset Hit Count
C. with a dataplane reboot
D. in the CLI, type command reset hitcount <POLICY-NAME>

Answer: A
