質問 # 12
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. tcp dump snaplen 53 filter "tcp 53"
- B. tcpdump snaplen 0 filter "port 53"
- C. tcpdump snaplen 53 filter "port 53"
- D. tcp dump snap-en 0 filter "app dns"
正解：B
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 # 15
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. debug log-sender statistics
- B. logging status
- C. debug log-receiver statistics
- D. show log traffic
正解：C
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.

質問 # 28
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：B
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

正解：A
解説：
If a firewall that was previously connected to a User-ID agent server now shows disconnected, the likely cause is:
D:The firewall was upgraded to a PAN-OS version that is not compatible with the agent version When a firewall is upgraded to a new version of PAN-OS, there can be compatibility issues with the existing User-ID agent if it is not updated accordingly. This can result in the firewall being unable to communicate with the User-ID agent, showing it as disconnected.
