Virtual Wire: Used when you have a transparent mode firewall deployment, where the firewall operates at Layer 2 to monitor traffic between two network segments.
Layer 2: Also used in transparent mode, where the firewall operates as a Layer 2 device and can be configured for link monitoring.
Layer 3: Used in routed mode, where the firewall is involved in routing traffic and can also be configured to monitor links.
NEW QUESTION # 18
What is the purpose of assigning an Admin Role Profile to a user in a Palo Alto Networks NGFW?
- A. Restrict access to sensitive report data.
- B. Enable multi-factor authentication (MFA) for administrator access.
- C. Allow access to all resources without restrictions.
- D. Define granular permissions for management tasks.
Answer: D
Explanation:
Assigning an Admin Role Profile to a user in a Palo Alto Networks NGFW is used to define granular permissions for management tasks. This allows administrators to control what actions a user can perform on the firewall, such as configuration changes, monitoring, and logging. By assigning different admin roles, you can ensure that users have access only to the areas and tasks they need, enforcing the principle of least privilege.
NEW QUESTION # 19
Which statement applies to Log Collector Groups?
- A. Enabling redundancy increases the log processing traffic in a Collector Group by 50%.
- B. The maximum number of Log Collectors in a Log Collector Group is 18 plus two hot spares.
- C. In any single Collector Group, all the Log Collectors must run on the same Panorama model.
- D. Log redundancy is available only if each Log Collector has the same amount of total disk storage.
Answer: B
Explanation:
The maximum number of Log Collectors that can be added to a Log Collector Group is 18 plus 2 hot spares, ensuring redundancy and availability in case of failure. This allows for a total of up to 20 Log Collectors in a group, providing sufficient scalability and reliability for log collection.
NEW QUESTION # 20
By default, which type of traffic is configured by service route configuration to use the management interface?
- A. Virtual system (VSYS)
- B. Security zone
- C. Autonomous Digital Experience Manager (ADEM)
- D. IPSec tunnel
Answer: C
Explanation:
By default, the Autonomous Digital Experience Manager (ADEM) traffic is configured to use the management interface in a Palo Alto Networks firewall. The management interface is typically used for management-related traffic, such as monitoring and logging, and it is configured to handle ADEM-related traffic for the optimal performance of digital experience monitoring features.
This default configuration helps ensure that ADEM traffic does not interfere with regular traffic that may traverse other interfaces, such as traffic from security zones or IPSec tunnels.
NEW QUESTION # 21
After an engineer configures an IPSec tunnel with a Cisco ASA, the Palo Alto Networks firewall generates system messages reporting the tunnel is failing to establish.
Which of the following actions will resolve this issue?
- A. Validate the tunnel interface VLAN against the peer's configuration.
- B. Configure the Proxy IDs to match the Cisco ASA configuration.
- C. Ensure that an active static or dynamic route exists for the VPN peer with next hop as the tunnel interface.
- D. Check that IPSec is enabled in the management profile on the external interface.
Answer: B
Explanation:
The Proxy IDs (or Traffic Selectors) define the local and remote subnets that are allowed to communicate over the IPSec tunnel. If the Proxy IDs on the Palo Alto Networks firewall do not match the configuration on the Cisco ASA, the tunnel will fail to establish because the firewalls won't agree on which traffic to encrypt. Ensuring that the Proxy IDs match between the Palo Alto Networks firewall and the Cisco ASA will resolve the issue.
NEW QUESTION # 22
Which two zone types are valid when configuring a new security zone? (Choose two.)
- A. Intrazone
- B. Internal
- C. Virtual Wire
- D. Tunnel
Answer: C,D
Explanation:
When configuring a new security zone on a Palo Alto Networks firewall, the two valid zone types are:
Tunnel: A Tunnel zone is used for traffic that is associated with a VPN tunnel, such as IPSec tunnels. Traffic passing through a tunnel interface is classified into this zone.
Virtual Wire: A Virtual Wire zone is used when a firewall operates in transparent mode (also known as Layer 2 mode). In this configuration, the firewall can inspect traffic without modifying the IP address structure of the network.
NEW QUESTION # 23
Which statement describes the role of Terraform in deploying Palo Alto Networks NGFWs?
- A. It provides Infrastructure-as-Code (IaC) to automate NGFW deployment.
- B. It orchestrates real-time traffic inspection for network segments.
- C. It manages threat intelligence data synchronization with NGFWs.
- D. It acts as a logging service for NGFW performance metrics.
Answer: A
Explanation:
Terraform is an Infrastructure-as-Code (IaC) tool that automates the provisioning and management of infrastructure resources, including Palo Alto Networks Next-Generation Firewalls (NGFWs). By using Terraform configuration files, administrators can define and deploy NGFW instances across cloud environments (such as AWS, Azure, and GCP) efficiently and consistently.
Terraform enables:
Automated firewall deployment in cloud environments.
Configuration of security policies and networking settings in a declarative manner.
Scalability and repeatability, reducing manual intervention in firewall provisioning.
NEW QUESTION # 24
An NGFW engineer is configuring multiple Layer 2 interfaces on a Palo Alto Networks firewall, and all interfaces must be assigned to the same VLAN. During initial testing, it is reported that clients located behind the various interfaces cannot communicate with each other.
Which action taken by the engineer will resolve this issue?
- A. Configure each interface to belong to the same Layer 2 zone and enable IP routing between them.
- B. Assign each interface to the appropriate Layer 2 zone and configure Security policies for interfaces not assigned to the same zone.
- C. Enable IP routing between the interfaces and configure a Security policy to allow traffic between interfaces within the VLAN.
- D. Assign each interface to the appropriate Layer 2 zone and configure a policy that allows traffic within the VLAN.
Answer: D
Explanation:
In a Layer 2 configuration, interfaces are typically grouped into the same Layer 2 zone. When the interfaces are assigned to the same VLAN, the firewall will treat them as part of the same broadcast domain.
In a Layer 2 setup, interfaces must be in the same Layer 2 zone to allow the traffic within the same VLAN to pass. Additionally, a security policy must be configured to allow traffic within this VLAN or zone. This will resolve the issue by ensuring that traffic is permitted between clients behind different interfaces assigned to the same VLAN.
NEW QUESTION # 25
Which two statements describe an external zone in the context of virtual systems (VSYS) on a Palo Alto Networks firewall? (Choose two.)
- A. It is not associated with an interface; it is associated with a VSYS itself.
- B. It is associated with an interface within a VSYS of a firewall.
- C. It is a security object associated with a specific VSYS.
- D. It is a security object associated with a specific virtual router of a VSYS.
Answer: B,C
Explanation:
In the context of virtual systems (VSYS) on a Palo Alto Networks firewall, the external zone is typically associated with specific interfaces within a VSYS. Zones are fundamental security objects used to define traffic flow between interfaces, and the external zone would be used for interfaces that connect to external networks.
An external zone is associated with an interface within a VSYS of the firewall. This ensures that traffic from specific interfaces can be classified as belonging to the external zone, allowing the firewall to apply appropriate security policies.
The external zone is indeed a security object that is specific to a given VSYS, as each VSYS can have its own set of zones that are isolated from others.
NEW QUESTION # 26
What is a result of enabling split tunneling in the GlobalProtect portal configuration with the "Both Network Traffic and DNS" option?
- A. lt allows devices on a local network to access blocked websites by changing which DNS server resolves certain domain names.
- B. It specifies which domains are resolved by the VPN-assigned DNS servers and which domains are resolved by the local DNS servers.
- C. It specifies when the secondary DNS server is used for resolution to allow access to specific domains that are not managed by the VPN.
- D. It allows users to access internal resources when connected locally and external resources when connected remotely using the same FQDN.
Answer: B
Explanation:
When split tunneling is enabled with the "Both Network Traffic and DNS" option in the GlobalProtect portal configuration, it allows the firewall to control which traffic is sent over the VPN tunnel and which is not. Specifically, it determines which domains are resolved by the VPN-assigned DNS servers (for domains requiring VPN access) and which are resolved by local DNS servers (for domains that can be accessed without the VPN tunnel).
NEW QUESTION # 27
A PA-Series firewall with all licensable features is being installed. The customer's Security policy requires that users do not directly access websites. Instead, a security device must create the connection, and there must be authentication back to the Active Directory servers for all sessions.
Which action meets the requirements in this scenario?
- A. Deploy the explicit proxy with Kerberos authentication scheme.
- B. Deploy the Advanced URL Filtering license and captive portal.
- C. Deploy the transparent proxy with Web Cache Communications Protocol (WCCP).
- D. Deploy the Next-Generation Firewalls as normal and install the User-ID agent.
Answer: A
Explanation:
In this scenario, the customer requires that users do not directly access websites and that a security device (the firewall) manages the connection, while also ensuring that there is authentication back to the Active Directory (AD) servers for all sessions. The explicit proxy with Kerberos authentication is the best solution because:
The explicit proxy allows the firewall to intercept user web traffic and manage the connections on behalf of users.
Kerberos authentication ensures that the user's identity is validated against the Active Directory servers before the session is allowed, fulfilling the authentication requirement.
NEW QUESTION # 28
Which PAN-OS method of mapping users to IP addresses is the most reliable?
- A. Server monitoring
- B. GlobalProtect
- C. Port mapping
- D. Syslog
Answer: A
Explanation:
Server monitoring is the most reliable method for mapping users to IP addresses in PAN-OS. This method allows the firewall to monitor specific servers, such as Microsoft Active Directory (AD) or LDAP servers, to dynamically retrieve and update user-to-IP mappings. It provides a more accurate and up-to-date mapping of users to their associated IP addresses, as it directly queries user databases in real time.
NEW QUESTION # 29
Which configuration in the LACP tab will enable pre-negotiation for an Aggregate Ethernet (AE) interface on a Palo Alto Networks high availability (HA) active/passive pair?
- A. Set "Enable in HA Passive State."
- B. Set LACP mode to "Active."
- C. Set passive link state to "Auto."
- D. Set Transmission Rate to "fast."
Answer: A
Explanation:
In a High Availability (HA) active/passive pair configuration, when setting up an Aggregate Ethernet (AE) interface, enabling the "Enable in HA Passive State" option allows the interface to participate in LACP (Link Aggregation Control Protocol) even when the system is in the passive state. This ensures that the pre-negotiation of the LACP link occurs, allowing the link aggregation to be ready as soon as the firewall becomes active.
NEW QUESTION # 30
Without performing a context switch, which set of operations can be performed that will affect the operation of a connected firewall on the Panorama GUI?
- A. Modification of post NAT rules, creation of new views on the local firewall ACC tab, creation of local custom reports
- B. Restarting the local firewall, running a packet capture, accessing the firewall CLI
- C. Modification of local security rules, modification of a Layer 3 interface, modification of the firewall device hostname
- D. Modification of pre-security rules, modification of a virtual router, modification of an IKE Gateway Network Profile
Answer: C
Explanation:
In Panorama, without performing a context switch, the administrator can perform local configuration tasks directly on the connected firewall. The following operations can be done:
Modification of local security rules: Security rules can be modified directly on the connected firewall from the Panorama GUI.
Modification of a Layer 3 interface: Changes to the Layer 3 interfaces on the connected firewall can be done from Panorama, without needing to switch to the firewall's local interface.
Modification of the firewall device hostname: The firewall's hostname can be changed via Panorama.
NEW QUESTION # 31
Which two actions in the IKE Gateways will allow implementation of post-quantum cryptography when building VPNs between multiple Palo Alto Networks NGFWs? (Choose two.)
- A. Select IKE v2, enable the Advanced Options * PQ KEM, then create an IKE Crypto Profile with Advanced Options adding one or more "Rounds."
- B. Select IKE v2 Preferred, enable the Advanced Options * PQ KEM, then add one or more "Rounds."
- C. Ensure Authentication is set to "certificate," then import a post-quantum derived certificate.
- D. Select IKE v2, enable the Advanced Options * PQ PPK, then set a 64+ character string for the post-quantum pre shared key.
Answer: A,B
Explanation:
To implement post-quantum cryptography (PQC) in VPNs between Palo Alto Networks NGFWs, you would enable the PQ KEM (Post-Quantum Key Encapsulation Mechanism) in the IKE gateway configuration. This enables the firewall to use quantum-resistant encryption for key exchange, which is an essential part of securing communications against the potential future threats posed by quantum computing.
By selecting IKE v2 Preferred and enabling the PQ KEM option under Advanced Options, you can add specific Rounds for the post-quantum cryptography process, which will help in implementing quantum-resistant key exchange methods.
This option similarly selects IKE v2 and enables PQ KEM while also creating a dedicated IKE Crypto Profile with the necessary Rounds configured for post-quantum cryptography.
NEW QUESTION # 32
Which statement applies to the relationship between Panorama-pushed Security policy and local firewall Security policy?
- A. The order of policy evaluation can be configured differently in different device groups.
- B. When a policy match is found in a local firewall policy, if any Panorama shared post-rule is configured, it will still be evaluated.
- C. Panorama post-rules can be configured to be evaluated before local firewall policy for the purpose of troubleshooting.
- D. Local firewall rules are evaluated after Panorama pre-rules and before Panorama post-rules.
Answer: D
Explanation:
Local firewall rules are evaluated after Panorama pre-rules (those applied before the firewall's local policies) and before Panorama post-rules (those applied after the firewall's local policies). This ensures that the local firewall rules do not override the central Panorama policy and are only applied in the appropriate order within the policy evaluation sequence.
