After importing a pre-configured firewall configuration to Panorama, what step is required to ensure a commit/push is successful without duplicating local configurations?
- A. Push the Device Group first, then push Template to the newly managed firewall
- B. Push the Template first, then push Device Group to the newly managed firewal.
- C. Ensure Force Template Values is checked when pushing configuration.
- D. Perform the Export or push Device Config Bundle to the newly managed firewall.
Answer: D
Explanation:
When importing a pre-configured firewall configuration to Panorama, you need to perform the following steps12:
Add the serial number of the firewall under Panorama > Managed Devices
In Panorama, import the firewall's configuration bundle under Panorama > Setup > Operations > Import device configuration to Panorama Make changes to the imported firewall configuration within Panorama Commit the changes you made to Panorama Perform an Export or push Device Config Bundle operation under Panorama > Setup > Operations The Export or push Device Config Bundle operation allows you to push a complete configuration bundle from Panorama to a managed firewall without duplicating local configurations3. This operation ensures that any local settings on the firewall are preserved and merged with the settings from Panorama.
NEW QUESTION # 54
Which three firewall multi-factor authentication factors are supported by PAN-OS? (Choose three)
- A. One-Time Password
- B. SSH key
- C. User logon
- D. Push
- E. Short message service
Answer: A,C,D
Explanation:
Explanation
According to Palo Alto Networks documentation123, multi-factor authentication (MFA) is a method of verifying a user's identity using two or more factors, such as something they know, something they have, or something they are.
The firewall supports MFA for administrative access, GlobalProtect VPN access, and Captive Portal access.
The firewall can integrate with external MFA providers such as RSA SecurID, Duo Security, or Okta Verify.
The three firewall MFA factors that are supported by PAN-OS are:
* User logon: This is something the user knows, such as a username and password.
* One-Time Password: This is something the user has, such as a code generated by an app or sent by email or SMS.
* Push: This is something the user is, such as a biometric verification or a device approval.

NEW QUESTION # 56
Which log type will help the engineer verify whether packet buffer protection was activated?
- A. Configuration
- B. Data Filtering
- C. Traffic
- D. Threat
Answer: D
Explanation:
Explanation
The log type that will help the engineer verify whether packet buffer protection was activated is Threat Logs.
Threat Logs are logs generated by the Palo Alto Networks firewall when it detects a malicious activity on the network. These logs contain information about the source, destination, and type of threat detected. They also contain information about the packet buffer protection that was activated in response to the detected threat.
This information can help the engineer verify that packet buffer protection was activated and determine which actions were taken in response to the detected threat.
Packet buffer protection is a feature that prevents packet buffer exhaustion by dropping packets, discarding sessions, or blocking source IP addresses when the packet buffer utilization exceeds a certain threshold. The firewall records these events in the threat log with different threat IDs and names1. The system log also records an alert event when the packet buffer congestion reaches the alert threshold2. The other types of logs do not show packet buffer protection events. References:

NEW QUESTION # 58
Panorama provides which two SD-WAN functions? (Choose two.)
- A. physical network links
- B. network monitoring
- C. data plane
- D. control plane
Answer: C,D
Explanation:
How Does SD-WAN Work?
Traditional WANs rely on physical routers to connect remote or branch users to applications hosted on data centers. Each router has a [data plane], which holds the information, and a
[control plane], which tells the data where to go. Where data flows is typically determined by a network engineer or administrator who writes rules and policies, often manually, for each router on the network - a process that can be time-consuming and prone to errors.
SD-WAN separates the control and management processes from the underlying networking hardware, making them available as software that can be easily configured and deployed. A centralized control pane means network administrators can write new rules and policies, and then configure and deploy them across an entire network at once.

NEW QUESTION # 60
Which User-ID mapping method should be used in a high-security environment where all IP address-to-user mappings should always be explicitly known?
- A. GlobalProtect
- B. Windows-based User-ID agent
- C. PAN-OS integrated User-ID agent
- D. LDAP Server Profile configuration
Answer: A
Explanation:
https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-admin/user-id/user-id-concepts/user-mapping/globalprotect.html Because GlobalProtect users must authenticate to gain access to the network, the IP address-to-username mapping is explicitly known.
Because GlobalProtect users must authenticate to gain access to the network, the IP address-to-username mapping is explicitly known. This is the best solution in sensitive environments where you must be certain of who a user is in order to allow access to an application or service. https://docs.paloaltonetworks.com/pan-os/10-1/pan-os-admin/user-id/user-id-concepts/user-mapping/globalprotect.html
"On sensitive and high security networks, WMI probing increases the overall attack surface, and administrators are recommended to disable WMI probing and instead rely upon User-ID mappings obtained from more isolated and trusted sources, such as domain controllers. If you are using the User-ID Agent to parse AD security event logs, syslog messages, or the XML API to obtain User-ID mappings, then WMI probing should be disabled. Captive portal can be used as a fallback mechanism to re-authenticate users where security event log data may be stale."

NEW QUESTION # 63
A superuser is tasked with creating administrator accounts for three contractors. For compliance purposes, all three contractors will be working with different device-groups in their hierarchy to deploy policies and objects Which type of role-based access is most appropriate for this project?
- A. Create a Custom Panorama Admin
- B. Create a Dynamic Read only superuser.
- C. Create a Dynamic Admin with the Panorama Administrator role
- D. Create a Device Group and Template Admin
Answer: D
Explanation:
Custom Panorama Admin: Custom Panorama Admin roles allow you to customize the elements of Panorama that an administrator can access. You can hide tabs in the web interface, you can set specific items in Panorama to read-only, or you can limit an administrator's access to Panorama plugins. Custom Panorama Admin roles require planning and configuration, but they provide extensive flexibility because you can control what administrators can access through the web interface or the CLI. Device Group and Template Admin:
Device Group and Template Admin roles also require configuration because there are no built-in examples.
These Admin Roles allow you to define which Panorama templates or Panorama device groups an administrator can access and configure. You can hide tabs in the web interface or set specific items to read only to control what administrators can configure.
