質問 # 36
In preparation for a cutover event, what two processes or procedures should be verified? (Choose two)
- A. logging and reporting
- B. auditing
- C. roles and responsibilities
- D. change management requirements
正解：C、D
解説：
For any cutover event, especially when dealing with network security infrastructure like Palo Alto Networks firewalls, it is critical to ensure that:
* Change Management Requirements (B):This involves verifying that all planned changes have been approved, documented, and communicated to all relevant stakeholders. The change management process ensures that any modifications are controlled, predictable, and include a rollback plan in case of issues.
Reference: Palo Alto Networks Best Practices for Change Management Documentation.
* Roles and Responsibilities (C):Clearly defined roles and responsibilities ensure that everyone involved knows their specific tasks during the cutover. This reduces confusion, ensures accountability, and helps in the smooth execution of the cutover plan. It includes defining who is responsible for specific tasks, who needs to be notified, and who has the authority to make decisions. Reference: Palo Alto Networks Operational Best Practices Documentation.
質問 # 37

When planning a deployment involving Firewall, Panorama, and Cortex XDR, each stakeholder plays a specific role:
* Security Engineer- This role involves defining and managing security policies, logging configurations, and reporting requirements to ensure compliance and optimal security posture. They are responsible for the overall security configuration and implementation.
質問 # 38
A client has a sensitive application server in their data center and is particularly concerned about resource exhaustion because of distributed denial-of-service attacks.
How can the Palo Alto Networks NGFW be configured to specifically protect tins server against resource exhaustion originating from multiple IP address (DDoS attack)?
- A. Add a DoS Protection Profile with defined session count.
- B. Define a custom App-ID to ensure that only legitimate application traffic reaches the server
- C. Add QoS Profiles to throttle incoming requests.

質問 # 39
Your customer believes that the Panorama appliance is being overwhelmed by the logs from deployed Palo Alto Networks Next-Generation Firewalls.What CLl command can you run to determine the number oflogs per second sent by each firewall?
- A. logging status
- B. show log traffic
- C. debug log-sender statistics
- D. debug log-receiver statistics
正解：D
解説：
To determine the number of logs per second sent by each firewall to a Panorama appliance, the appropriate CLI command to use is:
D:debug log-receiver statistics
This command provides detailed statistics about the logs being received by the Panorama, including the rate at which logs are being sent by each connected firewall. This information can help identify whether the Panorama is being overwhelmed by the volume of logs and which firewalls are contributing the most to the log traffic.

You are hosting a public-facing web server on your DMZ and access to that server is through a Palo Alto Networks firewall Both internal clients and internet clients access this web server using the FQDN public webserver acme com which resolves to the public address of 99.99 99.2 Which combination of NAT policies is necessary to enable access to the web server for both internal and internet clients?
- A.
- B.
- C.
- D.
正解：A
解説：
To enable access to a public-facing web server for both internal and internet clients using the FQDNpublic.webserver.acme.com, which resolves to the public address99.99.99.2, the necessary combination of NAT policies is:C.Option C
* Policy 11: DMZ to Untrust
* Source Zone: DMZ
* Destination Zone: Untrust
* Destination Address:Web_Server_Public_99.99.99.2
* Destination Translation:address: Web_Server_Private_172.16.1.2
* Policy 12: Untrust to Untrust
* Source Zone: Untrust
* Destination Zone: Untrust
* Destination Address:Web_Server_Public_99.99.99.2
* Destination Translation:address: Web_Server_Private_172.16.1.2
These policies ensure that traffic destined for the public IP address99.99.99.2from both the DMZ and Untrust zones is properly translated to the internal web server's private IP address172.16.1.2.

質問 # 46
A customer is adding a new site-to-site tunnel from a PaloAlto Networks NGFW to a third party with a policy based VPN peer After the initial configuration is completed and the changes are committed, phase 2 fails to establish Which two changes may be required to fix the issue? (Choose two)
- A. Verify that PFS is enabled on both ends
- B. Add proxy IDs to the iPsec tunnel configuration
- C. Verity that the certificate used tor authentication is installed.
- D. Enable the NAT Traversal advanced option.
正解：A、B
解説：
When configuring a site-to-site VPN between a Palo Alto Networks Next-Generation Firewall (NGFW) and a third-party device with a policy-based VPN peer, Phase 2 failures can often be attributed to configuration mismatches or missing parameters. Here are the two changes that may be required to fix the issue:
B:Verify that PFS is enabled on both ends: Perfect Forward Secrecy (PFS) is a method that ensures the security of cryptographic keys. Both ends of the VPN tunnel need to agree on whether PFS is used. If PFS is enabled on one side but not the other, Phase 2 will fail. Verify the PFS settings and ensure they are matched on both the Palo Alto firewall and the third-party VPN device.
D:Add proxy IDs to the IPsec tunnel configuration: Proxy IDs (or traffic selectors) define the specific local and remote IP ranges that are allowed to communicate through the VPN tunnel.They are particularly crucial when dealing with policy-based VPNs. If the proxy IDs are not correctly configured, Phase 2 negotiations will fail. Add the appropriate proxy IDs to the IPsec tunnel configuration to match the policy-based VPN settings of the third-party device.

質問 # 51
Instead of disabling App-IDs regularly, a security policy rule is going to be configured to temporarily allow new App-IDs. In which two circumstances is it valid to disable App-IDs as part of content update-?
(Choose two)
- A. when an organization operates a mission-critical network and has zero tolerance for downtime
- B. when planning to enable the App-IDs immediately
- C. when disabling facebook-base to disable all other Facebook App-IDs
- D. when you want to immediately benefit from the latest threat prevention
正解：A、D
解説：
Disabling App-IDs as part of a content update can be valid in the following circumstances:
B:When you want to immediately benefit from the latest threat prevention: Disabling certain App-IDs can help ensure that the latest threat prevention measures are applied without waiting for the App-IDs to be fully tested in a specific environment. This can be crucial in quickly addressing emerging threats.
D:When an organization operates a mission-critical network and has zero tolerance for downtime: In such environments, administrators might temporarily disable new or modified App-IDs to avoid potential disruptions caused by unverified or untested App-IDs. This ensures that the network remains stable and functional while the new App-IDs are evaluated in a controlled manner.
