質問 # 205
An engineer must configure the Decryption Broker feature. To which router must the engineer assign the decryption forwarding interfaces that are used in Decryption Broker security chain?
- A. The virtual router that routes the traffic that the Decryption Broker security chain inspects.
- B. The default virtual router. If there is no default virtual router , the engineer must create one during setup.
- C. A virtual router that has no additional interfaces for passing data-type traffic and no other configured routes than those used for the security chain.
- D. A virtual router that is configured with at least one dynamic routing protocol and has at least one entry in the RIB
正解：A
解説：
Decryption Broker is a feature that allows you to use a Palo Alto Networks firewall as a decryption broker for other security devices in your network. It works by decrypting traffic on one interface and forwarding it to another interface where it can be inspected by other devices before being re- encrypted and sent to its destination. The firewall acts as a transparent bridge between the two interfaces and does not change the source or destination IP addresses of the traffic. To configure Decryption Broker, you need to assign decryption forwarding interfaces (DFIs) to the virtual router that routes the traffic that you want to inspect. The DFIs are used to forward decrypted traffic from one interface to another in a security chain. A security chain is a set of devices that perform different security functions on the same traffic flow. You can have multiple security chains for different types of traffic or different segments of your network. The reason why you need to assign DFIs to the virtual router that routes the traffic is because Decryption Broker uses routing tables to determine which DFI belongs to which security chain and how to forward traffic between them. If you assign DFIs to a different virtual router than the one that routes the traffic, Decryption Broker will not be able to find them or forward traffic correctly.
質問 # 206
A Network Administrator wants to deploy a Large Scale VPN solution. The Network Administrator has chosen a GlobalProtect Satellite solution. This configuration needs to be deployed to multiple remote offices and the Network Administrator decides to use Panorama to deploy the configurations.
How should this be accomplished?
- A. Create a Device Group with the appropriate IKE Gateway settings.
- B. Create a Template with the appropriate lKE Gateway settings.
- C. Create a Template with the appropriate lPSec tunnel settings.
- D. Create a Device Group with the appropriate lPSec tunnel settings.
正解：C
解説：
Note: The administrator of the satellite must enter the credentials when the satellite connects to the portal.
This is done on the satellite by navigating to Network > IPSec Tunnels and choosing "gateway info" and then clicking on "Enter Credentials".
質問 # 207
When overriding a template configuration locally on a firewall, what should you consider?
- A. Panorama will lose visibility into the overridden configuration
- B. The firewall template will show that it is out of sync within Panorama
- C. Only Panorama can revert the override
- D. Panorama will update the template with the overridden value
正解：A
解説：
Based on my knowledge out-of-sync message appear on Panorama only was perform a commit to Panorama but not pushed to the NGFW. https://live.paloaltonetworks.com/t5/general-topics/reason-for-out-of-sync-message-in-panorama/td-p/328292
質問 # 208

- B. Verify AutoFocus is enabled below Device Management tab.
- C. Verify AutoFocus status using CLI.
- D. Check for WildFire forwarding logs.
- E. Check the license
正解：B、E
質問 # 209
Which operation will impact the performance of the management plane?
- A. Generating a SaaS Application report
- B. Enabling DoS protection
- C. Enabling packet buffer protection
- D. Decrypting SSL sessions
正解：A
解説：
Explanation
According to the Palo Alto Networks documentation , generating a SaaS Application report can impact the performance of the management plane because it requires querying and processing a large amount of log data.
Therefore, the correct answer is B.
The other options are not related to the management plane performance:
Decrypting SSL sessions: This option affects the data plane performance, not the management plane performance. Decrypting SSL sessions consumes CPU resources on the data plane, which handles traffic processing and security enforcement Enabling DoS protection: This option also affects the data plane performance, not the management plane performance. Enabling DoS protection allows the firewall to detect and prevent denial-of-service (DoS) attacks by monitoring and limiting the rate of sessions and packets3.
Enabling packet buffer protection: This option also affects the data plane performance, not the management plane performance. Enabling packet buffer protection allows the firewall to monitor and control the packet buffer usage on each interface to prevent buffer exhaustion and packet drops4.

質問 # 210
How would an administrator configure a Bidirectional Forwarding Detection profile for BGP after enabling the Advance Routing Engine run on PAN-OS 10.2?
- A. create a BFD profile under Network > Routing > Routing Profiles > BFD and then select the BFD profile under Network > Virtual Router > BGP > General > Global BFD Profile
- B. create a BFD profile under Network > Network Profiles > BFD Profile and then select the BFD profile under Network > Virtual Router > BGP > BFD
- C. create a BFD profile under Network > Network Profiles > BFD Profile and then select the BFD profile under Network > Routing > Logical Routers > BGP > BFD
- D. create a BFD profile under Network > Routing > Routing Profiles > BFD and then select the BFD profile under Network > Routing > Logical Routers > BGP > General > Global BFD Profile
正解：D
解説：
The Advanced Routing Engine uses Logical Routers, not Virtual Routers.

質問 # 211
What is the best definition of the Heartbeat Interval?
- A. The frequency at which the HA peers check link or path availability
- B. The interval in milliseconds between hello packets
- C. The interval during which the firewall will remain active following a link monitor failure
- D. The frequency at which the HA peers exchange ping
正解：D
解説：
Explanation
"A "heartbeat-interval" CLI command was added to the election settings for HA, this interval has a 1000ms minimum for all Palo Alto Networks platforms and is an ICMP ping to the other device through the HA control link."https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClMaCAK
質問 # 212
Given the following snippet of a WildFire submission log, did the end user successfully download a file?
- A. No, because the action for the wildfire-virus is "reset-both."
- B. Yes, because the final action is set to "allow.''
- C. Yes, because both the web-browsing application and the flash file have the 'alert" action.
- D. No, because the URL generated an alert.
正解：A
解説：
* URL profile action alert.
* File Profile action alert.
* AV and Wildfire action Reset-both
* Policy Action Allow.
The firewall inspects the content as per all the security profiles attached to the original matching rule. If it results in threat detection, then the corresponding security profile action is taken.
