NEW QUESTION # 27
An administrator would like to override the default deny action for a given application and instead would like to block the traffic and send the ICMP code "communication with the destination is administratively prohibited" Which security policy action causes this?
- A. Drop, send ICMP Unreachable
- B. Drop
- C. Reset both
- D. Reset server
Answer: A
NEW QUESTION # 28
What is the default action for the SYN Flood option within the DoS Protection profile?
- A. Random Early Drop
- B. Alert
- C. Sinkhole
- D. Reset-client
Answer: A
Explanation:
Random Early Drop -The firewall uses an algorithm to progressively start dropping that type of packet. If the attack continues, the higher the incoming cps rate (above the Activate Rate) gets, the more packets the firewall drops. ..

NEW QUESTION # 34
A Palo Alto Networks firewall is configured for User-ID, integrating with an Active Directory domain controller. Users report that their security policies are not being correctly applied, and investigation reveals that User-ID mappings are frequently incorrect or missing for certain users, despite them being logged into the domain. The User-ID agent on the DC reports 'RPC Server is unavailable' when attempting to connect to some workstations. Which of the following is the MOST LIKELY underlying issue causing the inaccurate User-ID mappings and what is the primary diagnostic step on the firewall?
- A. The User-ID agent is configured to use 'Server Monitoring' instead of 'Event Log' monitoring, and the domain controller's security logs are not being successfully parsed. Change the User-ID agent configuration.
- B. The User-ID agent's service account lacks the necessary permissions to query WMI on the workstations. Verify service account permissions on the domain controller.
- C. Port 445 (SMB) or Port 135 (RPC Endpoint Mapper) is blocked between the User-ID agent and the affected workstations by Windows Firewall or an intermediate network device. Test connectivity using telnet <workstation-ip> 445 and telnet <workstation-ip> 135 from the User-ID agent server.
- D. The Palo Alto Networks firewall itself is unable to communicate with the User-ID agent or the domain controller. Verify connectivity from the firewall to the User-ID agent IP and DC IP on relevant ports (e.g., TCP 5007 for User-ID agent).
- E. DNS resolution issues are preventing the User-ID agent from resolving workstation hostnames to IP addresses. Verify DNS configuration on the User-ID agent server and perform nslookup for problematic workstations.
Answer: C
Explanation:
The specific error 'RPC Server is unavailable' when the User-ID agent tries to connect to workstations is a strong indicator of network connectivity issues (firewall, routing, or local Windows Firewall) blocking the necessary RPC/SMB ports (135 and 445) used by the User-ID agent to query user information from the workstations (e.g., via WMI or for probing). Option B directly addresses this by suggesting connectivity tests for these crucial ports. Option A (permissions) is plausible if RPC communication works but data isn't retrieved. Option C refers to the User-ID collection method, which isn't directly implied by 'RPC Server is unavailable' to workstations . Option D focuses on firewall-to- agent/DC, not agent-to-workstation communication. Option E (DNS) could cause issues, but 'RPC Server is unavailable' usually points to port blockage or service not running, not just name resolution.
NEW QUESTION # 35
A Palo Alto Networks Network Security Analyst is tasked with optimizing security posture by decommissioning legacy, unused firewall rules. The challenge is identifying rules that genuinely have no active sessions or hit counts over an extended period (e.g., 6 months), distinguishing them from rules that might be critical but rarely triggered (e.g., a failover rule). Additionally, the analyst needs to propose a phased deprecation process to minimize risk. Which approach, integrating Command Center, Activity Insights, and Policy Optimizer, is most robust?
- A. 1. In Policy Optimizer, specifically target 'any-any' rules with low hit counts. 2. For these rules, change action to 'Alert Only' and review Command Center daily for a week. 3. If no alerts, proceed with deletion.
- B. 1. In Activity Insights, generate a report of all 'Application Usage' and 'User Activity' over 6 months to understand baseline traffic. 2. In Policy Optimizer, use the 'Security Policy Rule Optimization' dashboard to filter for rules with low hit counts over the last 6 months. 3. For these rules, change the action to 'Deny with Logging' and observe Command Center for new 'deny' logs. 4. If no legitimate denies, decommission the rule.
- C. 1. Utilize Command Center to view real-time session information for all active rules. 2. Identify rules with no active sessions. 3. Use Activity Insights to confirm these rules haven't had recent activity. 4. Delete the confirmed unused rules.
- D. Use Policy Optimizer's 'Rule Usage' to identify rules with zero hit count over 6 months. 2. Delete these rules. 3. Monitor Command Center for any service disruptions.
- E. 1. In Policy Optimizer, use the 'Security Policy Rule Optimization' dashboard to identify rules with 'Low Usage'. 2. For rules identified as 'Low Usage' and having an 'any' source, destination, or service, change the rule's action to 'No Action' (or a similar audit mode if available) with logging enabled. 3. Monitor Command Center and Activity Insights over 3-6 months for any unintended traffic disruptions or legitimate session attempts hitting the 'No Action' rule. 4. If no issues, transition the rule to 'Deny' and then eventually delete after another grace period.
Answer: E
Explanation:
This is a comprehensive, risk-averse approach. Policy Optimizer's 'Security Policy Rule Optimization' is the core tool for identifying 'Low Usage' rules. The key differentiator here is the proposed phased deprecation: changing the rule to an 'audit mode' (like 'No Action' or setting an action that logs but doesn't block) first, and monitoring Command Center for real-time impact and Activity Insights for long-term trends. This allows for validation that the rule is truly unused without immediately causing an outage, especially for rarely-triggered but critical rules (like failover). Only after a prolonged monitoring period and confirmation of no impact should the rule be moved to 'Deny' and then finally deleted, minimizing risk.
NEW QUESTION # 36
At which point in the app-ID update process can you determine if an existing policy rule is affected by an app-ID update?
- A. after connecting the firewall configuration
- B. after downloading the update
- C. after installing the update
- D. after clicking Check New in the Dynamic Update window
Answer: D
NEW QUESTION # 37
What is a recommended consideration when deploying content updates to the firewall from Panorama?
- A. Content updates for firewall A/P HA pairs can only be pushed to the active firewall.
- B. Content updates for firewall A/A HA pairs need a defined master device.
- C. Before deploying content updates, always check content release version compatibility.
- D. After deploying content updates, perform a commit and push to Panorama.
Answer: C
NEW QUESTION # 38
Where does a user assign a tag group to a policy rule in the policy creation window?
- A. General tab
- B. Actions tab
- C. Application tab
- D. Usage tab
Answer: A
Explanation:
A user can assign a tag group to a policy rule in the policy creation window by selecting the General tab. A tag group is a collection of tags that can be used to identify and filter policy rules based on different criteria, such as function, location, or priority. A user can create a tag group on Panorama and assign it to a policy rule to apply the same set of tags to multiple firewalls or device groups1. To assign a tag group to a policy rule, the user needs to:
Select the General tab in the policy creation window.
Click the Tag Group drop-down menu and select the tag group that the user wants to assign to the policy rule.
Click OK to save the changes. The policy rule will inherit the tags from the tag group and display them in the Tag column.
NEW QUESTION # 39
A Security Administrator is implementing a new policy on a Palo Alto Networks firewall. The requirement is to allow specific internal users access to Salesforce, but only for the 'Sales Cloud' application, and block all other Salesforce functionalities. The organization also wants to enforce strict file transfer restrictions within this allowed Salesforce access. Which combination of Security Policy elements and profiles would be most effective and precise in achieving this goal?
- A. Source Zone: Trust, Source User: sales_team_group, Destination Zone: Untrust, Application: salesforce-base, Service: application-default, Actions: allow, Profile: File Blocking Profile (block all files).
- B. Source Zone: Trust, Source User: any, Destination Zone: Untrust, Application: salesforce-base, Service: tcp/443, Actions: allow, Profile: Data Filtering Profile (block sensitive data).
- C. Source Zone: Trust, Source User: sales_team_group, Destination Zone: Untrust, Application: any, Service: application-default, Actions: allow, Profile: URL Filtering Profile (allow salesforce.com), File Blocking Profile (block all files).
- D. Source Zone: Trust, Source IJser: sales_team_group, Destination Zone: Untrust, Application: salesforce-salescloud, Service: application-default, Actions: allow, Profile: File Blocking Profile (block executable & archives), WildFire Analysis Profile.
- E. Source Zone: Trust, Source User: sales_team_group, Destination Zone: Untrust, Application: salesforce-salescloud, Service: application-default, Actions: allow, Profile: File Blocking Profile (block executable & archives), Data Filtering Profile (block PII), Antivirus Profile, Vulnerability Protection Profile.
Answer: E
Explanation:
Option E is the most effective and precise. It utilizes App-ID (salesforce-salescloud) for granular application control, User-ID (sales_team_group) for user-specific access, and Content-ID profiles (File Blocking for specific file types, Data Filtering for sensitive data, Antivirus, and Vulnerability Protection) for comprehensive threat prevention and data loss prevention within the allowed application. Option B is good but E is more comprehensive in security profiles. Option A uses 'salesforce-base' which is too broad. Option C uses 'any' user and lacks App-ID granularity. Option D uses 'any' application and relies on URL filtering, which is less effective than App-ID for controlling application sub- functions.
NEW QUESTION # 40
An IoT smart building system uses BACnet/IP for HVAC control. The security team discovers a device sending unauthorized 'Write Property' requests to BACnet objects that control critical ventilation fans, potentially disrupting air quality. They have identified the rogue device's MAC address and IP address, but its type (vendor/model) is not yet fully classified by Device-ID. How can the Palo Alto Networks NGFW be configured, leveraging IoT security concepts, to immediately block these specific 'Write Property' requests from this rogue device, while allowing legitimate BACnet traffic from authorized devices?
- A. Create a new 'Security Policy' rule with the rogue device's IP address as 'Source', the HVAC PLC's IP as 'Destination', 'Application: bacnet-ip', and a 'Service' of 'any', with an 'Action: Deny'. Place this rule highest in the rulebase.
- B. Configure an 'IP-MAC Binding' entry for the rogue device, then create a 'Threat Prevention' custom signature to detect the 'Write Property' request payload and block it.
- C. Create a new 'IoT Security Profile' specifically for the rogue device's IP address, enable 'Application Function Filtering' for BACnet/IP to block 'Write Property', and create a 'Security Policy' rule matching only this rogue device to apply this profile.
- D. Leverage a combination of 'IoT Device Group' for authorized BACnet devices, and an explicit 'Deny' rule that uses 'Application Function Filtering' for BACnet/Lp to block 'Write Property' requests, with 'Source: Any' and 'Destination: HVAC PLCs', placed higher than the allow rule.
- E. Within an existing 'IoT Security Profile' applied to BACnet traffic, configure 'Application Function Filtering' for BACnet/IP to block 'Write Property' function codes. Apply this profile to all relevant IoT policy rules.
Answer: C
Explanation:
Option C is the most precise and immediate solution given the constraint. While option B is generally good for all unauthorized 'Write Property' requests, it might impact legitimate devices if their 'Write Property' functions are also needed. Option C allows for surgical enforcement: it targets only the rogue device's traffic and applies the granular 'Application Function Filtering' (blocking 'Write Property') specifically to it. This ensures legitimate BACnet traffic from other devices continues unimpeded. Option A is too broad; it blocks all BACnet from the rogue device. Option D's 'Threat Prevention' custom signature is a more complex and potentially slower reaction than direct policy. Option E would block Write Property' from ALL devices, not just the rogue one, which contradicts the requirement to allow legitimate traffic.
NEW QUESTION # 41
Consider a large enterprise with multiple regional data centers and branch offices. They are deploying SD-WAN with Palo Alto Networks firewalls. The security team mandates that all Internet-bound traffic from branch offices must first be inspected by a centralized security stack (e.g., NGFW cluster, SWG) located in Region A Data Center, before exiting to the Internet. However, internal branch-to-branch communication should be routed directly over the optimal SD-WAN path without hair-pinning through a data center. All traffic types have their own application-specific SLA requirements. Which of the following policy constructs are essential and correctly ordered to satisfy these requirements?
- A. 1. PBF Rule: Match branch-to-branch traffic (source branch networks, destination branch networks) and specify 'no-forward' to SD-WAN. 2. SD-WAN Policy for Internet-bound traffic: Match all other traffic, apply application-specific SLAs, and configure 'Data Center Access' to Region A DC for Internet egress. 3. Security Policies: Allow/deny traffic as needed.
- B. 1. Policy-Based Forwarding (PBF) Rule: Match internet-bound traffic (destination 'Any', egress interface 'Intemet') and set next-hop to the tunnel interface leading to Region A DC. Set a PBF tag. 2. SD-WAN Policy: Create application-specific policies for branch-to-branch traffic with 'Dynamic Path Selection'. 3. Security Policy: Define security rules for all traffic types.
- C. 1. SD-WAN Policy for Internet-bound traffic: Define destination as 'Any' and egress interface as the tunnel to Region A DC. 2. PBF Rule: Match Internet-bound traffic and explicitly forward to the Region A DC tunnel. 3. SD-WAN Policy for Branch-to-Branch: Define specific internal network destinations and apply application-specific SLAs.
- D. 1. SD-WAN Policy for Internet-bound traffic: Match destination 'Any', configure 'Egress Interface' to the tunnel to Region A DC, and apply application-specific SLAs. 2. SD-WAN Policy for Branch-to-Branch traffic: Match internal destinations, and apply application-specific SLAs for direct path selection. 3. PBF Rule: Define a PBF rule with higher priority than SD-WAN policies to enforce Internet-bound traffic to the Region A D
- E. 1. SD-WAN Policy for Branch-to-Branch: Define internal destinations and apply appropriate application SLAs for direct routing. 2. SD-WAN Policy for Internet- bound traffic: Match destination 'Any', configure 'Data Center Access' pointing to Region A DC as the preferred egress for internet traffic, allowing SD-WAN to select the optimal tunnel based on DC availability and performance. 3. Security Policies: Ensure proper access controls.
Answer: B
Explanation:
Option D represents the most robust and Palo Alto Networks-centric solution. PBF rules are processed before SD-WAN policies and security policies. By creating a PBF rule for all Internet-bound traffic and forcing it to the Region A DC tunnel, the 'Internet hairpin' requirement is met. The PBF tag can optionally be used for further granular control or logging. Subsequently, SD-WAN policies can then intelligently handle branch-to-branch traffic based on application-specific SLAs, as they are not subject to the higher-priority PBF rule for Internet- bound traffic. Security policies then control what traffic is allowed/denied regardless of the path.
NEW QUESTION # 42
An organization is deploying a new custom application that runs over QUIC (Quick UDP Internet Connections) protocol, primarily for performance reasons. The firewall team needs to create a security policy to allow this application while ensuring it adheres to content inspection requirements, including SSL decryption. Currently, the firewall's default settings block unknown UDP traffic. Which configuration steps are necessary for the Palo Alto Networks firewall to successfully identify, decrypt, and apply content-ID to this QUIC application?
- A. QUIC is UDP-based; therefore, SSL decryption is not applicable. Create a Custom Application for QUIC traffic specifying UDP port. Create a Security Policy rule allowing this custom application. Apply relevant Content-ID profiles without SSL decryption.
- B. QUIC traffic, by its nature, integrates encryption directly at the transport layer. While a custom App-ID can identify it (if supported by signatures or application override), standard SSL decryption profiles designed for TCP-based SSL/TLS will not function directly on QUIC. A Security Policy rule allowing the custom App-Ld (or the 'quic' App-ID if recognized by the firewall) with appropriate Content-ID profiles (Antivirus, Anti-Spyware, WildFire) is required, but explicit SSL Decryption is generally not applied in the same manner as TCP.
- C. Create a Custom Application for QUIC traffic specifying UDP port. Create a Security Policy rule allowing this custom application. Configure an SSL Decryption Policy for this traffic. Apply relevant Content-ID profiles.
- D. Upgrade the PAN-OS to the latest version which has native support for QUIC decryption. Then, create a Security Policy rule allowing the 'quic' application and apply an SSL Decryption Profile along with Content-ID profiles. If the application is custom, a Custom App-ID might still be required.
- E. QUIC traffic uses a different handshaking mechanism than traditional SSL/TLS over TCP, making direct SSL decryption challenging for the firewall's standard SSL Proxy. The best approach is to use an Application Override for the QUIC traffic to identify it, then apply a specific Content-ID profile that bypasses SSL decryption but focuses on other threat prevention aspects. A Security Policy rule allowing this traffic is also needed.
Answer: B
Explanation:
Option D correctly identifies the challenge with QUIC. QUIC (HTTP/3) integrates TLS 1.3 directly into the UDP transport layer, making it fundamentally different from how traditional SSL/TLS (over TCP) is decrypted by firewalls. Standard SSL decryption profiles are designed for TCP sessions and will not directly decrypt QUIC. While Palo Alto Networks continues to enhance its App-ID and threat prevention for QUIC, explicit SSL decryption as applied to TCP-based traffic is not typically done in the same manner. The firewall will primarily rely on App-Ld for identification and then apply other Content-ID profiles like Antivirus, Anti-Spyware, and WildFire based on the identified application. Option E implies a direct native decryption feature which, while evolving, isn't the standard approach for custom QUIC apps in the same way as TCP SSL. Options A and C are incorrect in assuming standard SSL decryption or application override for decryption functionality will work directly. Option B is partially correct in stating SSL decryption is not applicable, but then implies standard content-ID would just work without acknowledging the encryption.
NEW QUESTION # 43
Review the Screenshot:
Given the network diagram, traffic must be permitted for SSH and MYSQL from the DMZ to the SERVER zones, crossing two firewalls. In addition, traffic should be permitted from the SERVER zone to the DMZ on SSH only.
Which rule group enables the required traffic?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Option B enables the required traffic by allowing SSL and web-browsing from UNTRUST to DMZ, denying SSH from UNTRUST to DMZ, allowing MYSQL from DMZ to SERVER, and allowing SSH from SERVER to DMZ. Option A allows SSH from UNTRUST to DMZ, which is not required. Option C denies all the required traffic. Option D denies all traffic from UNTRUST to TRUST, which is irrelevant to the question

NEW QUESTION # 44
Consider a scenario where your internal development team frequently uses a custom SFTP service running on TCP/2222 for secure file transfers, but Palo Alto Networks App-ID consistently identifies this traffic as 'unknown-tcp' due to variations in the SFTP handshake. You want to ensure that all traffic to and from the internal SFTP server on port 2222 is correctly identified as 'sftp' for accurate logging, threat prevention, and policy enforcement. Which of the following configuration steps would be most effective?
- A. Create an Application Override policy for source zone 'internal-dev', destination zone 'internal-sftp-server', service 'tcp/2222', and set the application to 'sftp'.
- B. Disable Deep Packet Inspection for TCP/2222 traffic to the SFTP server.
- C. Configure a Service Object for TCP/2222 and add it to the security policy, then enable App-ID on that policy.
- D. Create a custom application signature matching the SFTP handshake and apply it to a security policy.
- E. Modify the existing security policy to allow 'any' application on port 2222 and rely on threat prevention profiles.
Answer: A
Explanation:
An Application Override policy is designed for scenarios where App-ID might misidentify a known application, especially when it runs on a non-standard port or has subtle protocol variations. By creating an override, you force the firewall to classify the traffic as 'sftp' based on the specified criteria (source, destination, port), ensuring correct policy application and logging. Option A is feasible but more complex than an override for this specific use case. Options C, D, and E do not address the core problem of misidentification by App-ID.
