Question #2
Refer to the exhibit.

An organization has Palo Alto Networks NGFWs that send logs to remote monitoring and security management platforms. The network team has reported excessive traffic on the corporate WAN.
How could the Palo Alto Networks NGFW administrator reduce WAN traffic while maintaining support for all the existing monitoring/security platforms?
  1. A
    Forward logs from firewalls only to Panorama and have Panorama forward logs to other external services.
  2. B
    Forward logs from external sources to Panorama for correlation, and from Panorama send them to the NGFW.
  3. C
    Configure log compression and optimization features on all remote firewalls.
  4. D
    Any configuration on an M-500 would address the insufficient bandwidth concerns.

Correct Answer:
A

Question #3
A customer wants to set up a VLAN interface for a Layer 2 Ethernet port.
Which two mandatory options are used to configure a VLAN interface? (Choose two.)
  1. A
    Virtual router
  2. B
    Security zone
  3. C
    ARP entries
  4. D
    Netflow Profile

Correct Answer:
CD
chatbot-img GPT-4o - Answer
Upon reviewing the provided user comments and options listed in the question, it's clear that the correct answer reflects a misunderstanding in the typical mandatory configurations for setting up a VLAN interface. A VLAN interface primarily functions to provide Layer 3 connectivity to a VLAN, requiring linkage to a Virtual Router and inclusion within a Security Zone for proper operation. These settings ensure the interface can participate in routing and adhere to security policies, which is central to the deployment in a network scenario. The mention of ARP entries and Netflow Profile as mandatory elements does not align with standard mandatory requirements associated with VLAN interfaces for basic functionality.

Question #4
An administrator has been asked to configure a Palo Alto Networks NGFW to provide protection against worms and trojans.
Which Security Profile type will protect against worms and trojans?
  1. A
    Anti-Spyware
  2. B
    Instruction Prevention
  3. C
    File Blocking
  4. D
    Antivirus

Correct Answer:
D

Question #5
A company needs to preconfigure firewalls to be sent to remote sites with the least amount of preconfiguration. Once deployed, each firewall must establish secure tunnels back to multiple regional data centers to include the future regional data centers.
Which VPN configuration would adapt to changes when deployed to the future site?
  1. A
    Preconfigured GlobalProtect satellite
  2. B
    Preconfigured GlobalProtect client
  3. C
    Preconfigured IPsec tunnels
  4. D
    Preconfigured PPTP Tunnels

Correct Answer:
A
chatbot-img GPT-4o - Answer
In the context of a company looking to deploy firewalls with minimal initial configuration while also planning for scalable secure connections to current and future regional data centers, Preconfigured GlobalProtect satellite emerges as the optimal choice. This configuration streamlines the setup process and is inherently designed to automatically establish the necessary secure connections, adapting as new data centers come into play. This setup fosters efficiency by minimizing upfront manual configuration and allowing the network infrastructure to dynamically scale as the organization expands its geographical footprint.

Question #6
An administrator has been asked to configure active/passive HA for a pair of Palo Alto Networks NGFWs. The administrator assigns priority 100 to the active firewall.
Which priority is correct for the passive firewall?
  1. A
    0
  2. B
    99
  3. C
    1
  4. D
    255

Correct Answer:
D

Question #7
An administrator pushes a new configuration from Panorama to a pair of firewalls that are configured as an active/passive HA pair.
Which NGFW receives the configuration from Panorama?
  1. A
    The passive firewall, which then synchronizes to the active firewall
  2. B
    The active firewall, which then synchronizes to the passive firewall
  3. C
    Both the active and passive firewalls, which then synchronize with each other
  4. D
    Both the active and passive firewalls independently, with no synchronization afterward

Correct Answer:
D
chatbot-img GPT-4o - Answer
When deploying configurations to a high availability (HA) pair of firewalls through Panorama, it's critical to understand that both the active and passive firewalls receive the updates independently. This approach prevents any reliance on internal synchronization mechanisms for policy and template distribution, ensuring each firewall is updated directly by Panorama without syncing afterward. This method maintains consistency and eliminates the risk of configuration drift between the HA pair.

Question #8
An administrator cannot see any Traffic logs from the Palo Alto Networks NGFW in Panorama reports. The configuration problem seems to be on the firewall.
Which settings, if configured incorrectly, most likely would stop only Traffic logs from being sent from the firewall to Panorama?
A.

B.

C.

D.


Correct Answer:
B

Question #9
When configuring a GlobalProtect Portal, what is the purpose of specifying an Authentication Profile?
  1. A
    To enable Gateway authentication to the Portal
  2. B
    To enable Portal authentication to the Gateway
  3. C
    To enable user authentication to the Portal
  4. D
    To enable client machine authentication to the Portal

Correct Answer:
C
The additional options of Browser and Satellite enable you to specify the authentication profile to use for specific scenarios. Select Browser to specify the authentication profile to use to authenticate a user accessing the portal from a web browser with the intent of downloading the GlobalProtect agent (Windows and
Mac). Select Satellite to specify the authentication profile to use to authenticate the satellite.

Question #10
If a template stack is assigned to a device and the stack includes three templates with overlapping settings, which settings are published to the device when the template stack is pushed?
  1. A
    The settings assigned to the template that is on top of the stack.
  2. B
    The administrator will be promoted to choose the settings for that chosen firewall.
  3. C
    All the settings configured in all templates.
  4. D
    Depending on the firewall location, Panorama decides with settings to send.

Correct Answer:
A
chatbot-img GPT-4o - Answer
When using template stacks in Palo Alto Network's Panorama, it's crucial to understand how settings are prioritized. If there are overlapping settings across templates within a stack, the settings from the template located highest in the stack order are the ones that get pushed to the device. This hierarchical arrangement ensures a clear and systematic application of configurations, avoiding conflicts and maintaining consistency across managed devices. This functionality is well-documented and aligns with ensuring efficient and error-minimized configuration deployments.
