質問 # 29
TAC has requested a PCAP on your Panorama lo see why the DNS app is having intermittent issues resolving FODN What is the appropriate CLI command1*
- A. tcpdump snaplen 53 filter "port 53"
- B. tcp dump snaplen 53 filter "tcp 53"
- C. tcp dump snap-en 0 filter "app dns"
- D. tcpdump snaplen 0 filter "port 53"
正解：D
解説：
To capture a PCAP on your Panorama to troubleshoot DNS resolution issues, the appropriate CLI command is:
B:tcpdump snaplen 0 filter "port 53"
This command captures packets with no size limit (snaplen 0) and filters the traffic for port 53, which is used by DNS. This is the most straightforward and comprehensive way to capture all DNS traffic for analysis.

質問 # 30
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 you want to immediately benefit from the latest threat prevention
- B. when an organization operates a mission-critical network and has zero tolerance for downtime
- C. when disabling facebook-base to disable all other Facebook App-IDs
- D. when planning to enable the App-IDs immediately
正解：A、B
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.

質問 # 31
In preparation for a cutover event, what two processes or procedures should be verified? (Choose two)
- A. change management requirements
- B. auditing
- C. logging and reporting
- D. roles and responsibilities
正解：A、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.

- C. The three-way TCP handshake was observed, but the application could not be identified.
- D. The traffic is coming across UDP, and the application could not be identified.
正解：A
質問 # 34
Match the App-ID adoption task with its order in the process.
正解：
解説：
Explanation:
To match the App-ID adoption task with its order in the process, follow these steps:
* Perform a like-for-like (Layer 3/4) migration from the legacy firewall to the Palo Alto Networks NGFW.
* This is the initial step to ensure that the Palo Alto Networks NGFW is in place and functioning with the existing security policies.
* Capture, retain, and verify that all traffic has been logged for a period of time.
* This step involves enabling logging and monitoring traffic to understand the application usage and to ensure that all traffic is being logged.
* Clone the legacy rules and add application information to the intended application-based rules.
* This step involves creating copies of the existing rules and enhancing them with application-specific information using App-ID.
* Verify that no traffic is hitting the legacy rules.
* After creating application-based rules, ensure that traffic is now hitting these new rules instead of the legacy rules. This indicates that the transition to App-ID based policies is successful.
* Remove the legacy rules.
* Once it is confirmed that no traffic is hitting the legacy rules and the new App-ID based rules are effectively managing the traffic, the legacy rules can be safely removed.
Order in Process:
* Perform a like-for-like (Layer 3/4) migration from the legacy firewall to the Palo Alto Networks NGFW.
* Capture, retain, and verify that all traffic has been logged for a period of time.
* Clone the legacy rules and add application information to the intended application-based rules.
* Verify that no traffic is hitting the legacy rules.
* Remove the legacy rules.

質問 # 40
Which firewall interface type allows you to non-disruptively monitor traffic coming from a port operating in promiscuous mode?
- A. Layer
- B. Layer 3
- C. V-Wire
- D. TAP
正解：D
解説：
To non-disruptively monitor traffic coming from a port operating in promiscuous mode, the appropriate firewall interface type is:
D:TAP
A TAP (Test Access Point) interface allows the firewall to passively monitor network traffic without interfering with the actual flow of traffic. It is used to capture and analyze traffic for inspection, logging, and threat detection.
