NEW QUESTION # 123
An engineer is monitoring an active/active high availability (HA) firewall pair.
Which HA firewall state describes the firewall that is experiencing a failure of a monitored path?
- A. Active-secondary
- B. Initial
- C. Passive
- D. Tentative
Answer: D
Explanation:
In an active/active high availability (HA) firewall pair, when a firewall experiences a failure of a monitored path, it enters the "Tentative" state1. This state indicates that the firewall is synchronizing sessions and configurations from its peer due to a failure or a change in monitored objects such as a link or path. The firewall in this state is not fully functional but is working towards resuming normal operations by syncing with its peer. Therefore, the correct answer is B. Tentative.
NEW QUESTION # 124

Enable Packet Buffer Protection per ingress zone. - C. Enable per-vsys Session Threshold alerts and triggers for Packet Buffer Limits.

NEW QUESTION # 126
What happens, by default, when the GlobalProtect app fails to establish an IPSec tunnel to the GlobalProtect gateway?
- A. It stops the tunnel-establishment processing to the GlobalProtect gateway immediately.
- B. It tries to establish a tunnel to the GlobalProtect gateway using SSL/TLS.
- C. It tries to establish a tunnel to the GlobalProtect portal using SSL/TLS.
- D. It keeps trying to establish an IPSec tunnel to the GlobalProtect gateway.
Answer: B
Explanation:
The GlobalProtect VPN solution by Palo Alto Networks is designed to provide secure remote access to users. It primarily attempts to establish a VPN tunnel using the IPSec protocol for optimal security and performance. However, in cases where IPSec cannot be used due to network restrictions or other issues, GlobalProtect has a fallback mechanism.
C . It tries to establish a tunnel to the GlobalProtect gateway using SSL/TLS:
If the GlobalProtect app fails to establish an IPSec tunnel with the GlobalProtect gateway, the default behavior is to fallback to SSL/TLS for tunnel establishment. This ensures that the VPN connection can still be established, maintaining secure remote access for the user even in environments where IPSec is not feasible. SSL/TLS provides a secure tunnel, albeit generally with slightly less efficiency than IPSec.
This fallback mechanism is part of the GlobalProtect app's design to ensure reliability and continuous secure access for remote users under various network conditions.

NEW QUESTION # 128
What is the best description of the Cluster Synchronization Timeout (min)?
- A. The maximum interval between hello packets that are sent to verify that the HA functionality on the other firewall is operational
- B. The time that a passive or active-secondary firewall will wait before taking over as the active or active-primary firewall
- C. The maximum time that the local firewall waits before going to Active state when another cluster member is preventing the cluster from fully synchronizing
- D. The timeframe within which the firewall must receive keepalives from a cluster member to know that the cluster member is functional
Answer: C
Explanation:
The best description of the Cluster Synchronization Timeout (min) is the maximum time that the local firewall waits before going to Active state when another cluster member is preventing the cluster from fully synchronizing. This is a parameter that can be configured in an HA cluster, which is a group of firewalls that share session state and provide high availability and scalability. The Cluster Synchronization Timeout (min) determines how long the local firewall will wait for the cluster to reach a stable state before it decides to become Active and process traffic. A stable state means that all cluster members are either Active or Passive, and have synchronized their sessions with each other. If there is another cluster member that is in an unknown or unstable state, such as Initializing, Non-functional, or Suspended, then it may prevent the cluster from fully synchronizing and cause a delay in traffic processing. The Cluster Synchronization Timeout (min) can be set to a value between 0 and 30 minutes, with a default of 0. If it is set to 0, then the local firewall will not wait for any other cluster member and will immediately go to Active state. If it is set to a positive value, then the local firewall will wait for that amount of time before going to Active state, unless the cluster reaches a stable state earlier12.

NEW QUESTION # 130

NEW QUESTION # 132
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. 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.
- B. The virtual router that routes the traffic that the Decryption Broker security chain inspects.
- C. A virtual router that is configured with at least one dynamic routing protocol and has at least one entry in the RIB
- D. The default virtual router. If there is no default virtual router , the engineer must create one during setup.
Answer: B
Explanation:
Explanation
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 destination2. 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 them2. 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
NEW QUESTION # 133
When you configure a Layer 3 interface what is one mandatory step?
- A. Configure Interface Management profiles which need to be attached to each Layer 3 interface
- B. Configure service routes to route the traffic for each Layer 3 interface
- C. Configure virtual routers to route the traffic for each Layer 3 interface
- D. Configure Security profiles, which need to be attached to each Layer 3 interface
Answer: C
Explanation:
In a Layer 3 deployment, the firewall routes traffic between multiple ports. Before you can Configure Layer 3 Interfaces, you must configure the Virtual Routers that you want the firewall to use to route the traffic for each Layer 3 interface.

NEW QUESTION # 137
View the GlobalProtect configuration screen capture.
What is the purpose of this configuration?
- A. It enables a client to perform a reverse DNS lookup on 192.168.10.1 to detect that it is an internal client.
- B. It forces an internal client to connect to an internal gateway at IP address 192.168.10.1.
- C. It forces the firewall to perform a dynamic DNS update, which adds the internal gateway's hostname and IP address to the DNS server.
- D. It configures the tunnel address of all internal clients to an IP address range starting at 192.168.10.1.
Answer: A
Explanation:
Reference:
https://www.paloaltonetworks.com/documentation/80/globalprotect/globalprotect-admin-guide/globalprotect-portals/define- the-globalprotect-client-authentication-configurations/define-the-globalprotect-agent-configurations
"Select this option to allow the GlobalProtect agent to determine if it is inside the enterprise network. This option applies only to endpoints that are configured to communicate with internal gateways.
When the user attempts to log in, the agent does a reverse DNS lookup of an internal host using the specified Hostname to the specified IP Address. The host serves as a reference point that is reachable if the endpoint is inside the enterprise network. If the agent finds the host, the endpoint is inside the network and the agent connects to an internal gateway; if the agent fails to find the internal host, the endpoint is outside the network and the agent establishes a tunnel to one of the external gateways"
