NEW QUESTION # 10
An administrator plans to upgrade a pair of active/passive firewalls to a new PAN-OS release. The environment is highly sensitive, and downtime must be minimized.
What is the recommended upgrade process for minimal disruption in this high availability (HA) scenario?
- A. Suspend the active firewall to trigger a failover to the passive firewall. With traffic now running on the former passive unit, upgrade the suspended (now passive) firewall and confirm proper operation. Then fail traffic back and upgrade the remaining firewall.
- B. Push the new PAN-OS version simultaneously to both firewalls, having them upgrade and reboot in parallel. Rely on automated HA reconvergence to restore normal operations without manually failing over traffic.
- C. Shut down the currently active firewall and upgrade it offline, allowing the passive firewall to handle all traffic. Once the active firewall finishes upgrading, bring it back online and rejoin the HA cluster. Finally, upgrade the passive firewall while the newly upgraded unit remains active.
- D. Isolate both firewalls from the production environment and upgrade them in a separate, offline setup. Reconnect them only after validating the new software version, resuming HA functionality once both units are fully upgraded and tested.
Answer: A
Explanation:
In an active/passive HA setup, the recommended process for upgrading involves minimizing downtime and ensuring traffic continuity by using the failover process:
Suspend the active firewall: This triggers a failover to the passive unit, making it the active unit.
Upgrade the former passive (now active) unit: With traffic now running on the previously passive unit, upgrade the suspended unit while the active unit continues handling traffic.
Confirm proper operation: Once the upgrade is complete, verify that the upgraded unit is functioning properly.
Fail traffic back: Once the upgraded firewall is confirmed to be working, fail the traffic back to the original active unit and upgrade the remaining firewall.
NEW QUESTION # 11
A multinational organization wants to use the Cloud Identity Engine (CIE) to aggregate identity data from multiple sources (on premises AD, Azure AD, Okta) while enforcing strict data isolation for different regional business units. Each region's firewalls, managed via Panorama, must only receive the user and group information relevant to that region. The organization aims to minimize administrative overhead while meeting data sovereignty requirements.
Which approach achieves this segmentation of identity data?
- A. Create one CIE tenant, aggregate all identity data into a single view, and redistribute the full dataset to all firewalls. Rely on per-firewall Security policies to restrict access to out-of-scope user and group information.
- B. Deploy a single CIE tenant that collects all identity data, then configure segments within the tenant to filter and redistribute only the relevant user/group sets to each regional firewall group.
- C. Disable redistribution of identity data entirely. Instead, configure each regional firewall to pull user and group details directly from its local identity providers (IdPs).
- D. Establish separate CIE tenants for each business unit, integrating each tenant with the relevant identity sources. Redistribute user and group data from each tenant only to the region's firewalls, maintaining a strict one-to-one mapping of tenant to business unit.
Answer: D
Explanation:
To meet the requirement of data isolation for different regional business units while minimizing administrative overhead, the best approach is to establish separate Cloud Identity Engine (CIE) tenants for each business unit. Each tenant would be integrated with the relevant identity sources (such as on-premises AD, Azure AD, and Okta) for that specific region. This ensures that the identity data for each region is kept isolated and only relevant user and group data is distributed to the respective regional firewalls.
By maintaining a strict one-to-one mapping between CIE tenants and business units, the organization ensures that each region's firewall only receives the user and group data relevant to that region, thus meeting data sovereignty requirements and minimizing administrative complexity.
NEW QUESTION # 12
Which CLI command is used to configure the management interface as a DHCP client?
- A. set deviceconfig system type dhcp-client
- B. set network dhcp interface management
- C. set deviceconfig management type dhcp-client
- D. set network dhcp type management-interface
Answer: C
Explanation:
To configure the management interface as a DHCP client on a Palo Alto Networks NGFW, the correct CLI command is set deviceconfig management type dhcp-client.
This command configures the management interface to obtain an IP address dynamically using DHCP.
NEW QUESTION # 13
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. Check that IPSec is enabled in the management profile on the external interface.
- C. Ensure that an active static or dynamic route exists for the VPN peer with next hop as the tunnel interface.
- D. Configure the Proxy IDs to match the Cisco ASA configuration.
Answer: D
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 # 14
What must be configured before a firewall administrator can define policy rules based on users and groups?
- A. User Mapping profile
- B. Group mapping settings
- C. Authentication profile
- D. LDAP Server profile
Answer: B
Explanation:
Before a firewall administrator can define policy rules based on users and groups, the Group Mapping settings must be configured. These settings enable the firewall to map users to their respective Active Directory (AD) groups. This mapping allows the firewall to use user and group information to create policy rules based on group membership.
NEW QUESTION # 15
How does a Palo Alto Networks firewall choose the best route when it receives routes for the same destination from different routing protocols?
- A. It compares the administrative distance and chooses the one with the lowest value.
- B. It will attempt to load balance the traffic across all routes.
- C. It compares the administrative distance and chooses the one with the highest value.
- D. The route that was received first will be entered into the forwarding table, and all subsequent routes will be rejected.
Answer: A
Explanation:
When a Palo Alto Networks firewall receives routes for the same destination from different routing protocols, it uses the administrative distance (AD) to determine the best route. The administrative distance is a measure of the trustworthiness of a route, with a lower value indicating higher preference. The firewall will choose the route with the lowest administrative distance to populate its forwarding table.
NEW QUESTION # 16
What is a result of enabling split tunneling in the GlobalProtect portal configuration with the "Both Network Traffic and DNS" option?
- A. It allows users to access internal resources when connected locally and external resources when connected remotely using the same FQDN.
- B. It specifies when the secondary DNS server is used for resolution to allow access to specific domains that are not managed by the VPN.
- C. lt allows devices on a local network to access blocked websites by changing which DNS server resolves certain domain names.
- D. It specifies which domains are resolved by the VPN-assigned DNS servers and which domains are resolved by the local DNS servers.
Answer: D
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 # 17
Which forwarding methods can be used on the Objects tab when configuring the Log Forwarding profile?
- A. Syslog, HTTP, NetFlow
- B. Panorama, syslog, email
- C. Panorama, ADEM, syslog
- D. SNMP, HTTP, RADIUS
Answer: B
Explanation:
When configuring the Log Forwarding profile on a Palo Alto Networks firewall, the forwarding methods available include:
Panorama: For forwarding logs to a Panorama management system.
Syslog: For forwarding logs to a syslog server.
Email: For sending logs via email.
NEW QUESTION # 18
By default, which type of traffic is configured by service route configuration to use the management interface?
- A. Security zone
- B. Virtual system (VSYS)
- 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 # 19
Which two statements apply to configuring required security rules when setting up an IPSec tunnel between a Palo Alto Networks firewall and a third- party gateway? (Choose two.)
- A. For incoming and outgoing traffic through the tunnel, separate rules must be created for each direction.
- B. For incoming and outgoing traffic through the tunnel, creating separate rules for each direction is optional.
- C. The IKE negotiation and IPSec/ESP packets are allowed by default via the intrazone default allow policy.
- D. The IKE negotiation and IPSec/ESP packets are denied by default via the interzone default deny policy.
Answer: A,D
Explanation:
Separate rules must be created for each direction: Palo Alto Networks firewalls enforce security policies based on traffic direction. To allow bidirectional communication through the IPSec tunnel, two separate rules are required - one for incoming and one for outgoing traffic.
IKE negotiation and IPSec/ESP packets are denied by default: Palo Alto Networks firewalls use an interzone default deny policy, meaning that unless an explicit policy allows IKE (UDP 500/4500) and ESP (protocol 50) traffic, the firewall will block these packets, preventing tunnel establishment. Therefore, administrators must create explicit rules permitting IKE and IPSec/ESP traffic to the firewall's external interface.
NEW QUESTION # 20
Which PAN-OS method of mapping users to IP addresses is the most reliable?
- A. Syslog
- B. Server monitoring
- C. Port mapping
- D. GlobalProtect
Answer: B
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 # 21
According to dynamic updates best practices, what is the recommended threshold value for content updates in a mission- critical network?
- A. 48 hours
- B. 8 hours
- C. 16 hours
- D. 32 hours
Answer: B
Explanation:
For a mission-critical network, it is recommended to configure the content update threshold to 8 hours. This ensures that the network is protected with the latest threat intelligence, updates to signatures, and other critical content, minimizing the exposure to newly discovered vulnerabilities and threats.
Regular content updates are crucial in mission-critical environments to ensure the firewall is up-to-date with the latest protections. 8 hours is considered an optimal balance between timely updates and network performance.
NEW QUESTION # 22
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. Modification of pre-security rules, modification of a virtual router, modification of an IKE Gateway Network Profile
- C. Modification of local security rules, modification of a Layer 3 interface, modification of the firewall device hostname
- D. Restarting the local firewall, running a packet capture, accessing the firewall CLI
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 # 23
An engineer at a managed services provider is updating an application that allows its customers to request firewall changes to also manage SD-WAN. The application will be able to make any approved changes directly to devices via API.
What is a requirement for the application to create SD-WAN interfaces?
- A. XML API's "InterfaceProfiles/sdwan" parameter on a firewall device
- B. XML API's "sdwanprofiles/interfaces" parameter on a Panorama device
- C. REST API's "sdwanInterfaces" parameter on a firewall device
- D. REST API's "sdwanInterfaceprofiles" parameter on a Panorama device
Answer: C
Explanation:
To create SD-WAN interfaces through an API, the correct approach is to use the REST API's "sdwanInterfaces" parameter on a firewall device. This parameter allows you to configure SD-WAN interfaces directly on the firewall devices via API, ensuring that the required interfaces are set up and managed for SD-WAN functionality.
NEW QUESTION # 24
Which configuration step is required when implementing a new self-signed root certificate authority (CA) certificate for SSL decryption on a Palo Alto Networks firewall?
- A. Import the new subordinate CA certificate into the trust stores of all client devices.
- B. Disable all existing SSL decryption rules until the new certificate is fully propagated.
- C. Configure the subordinate CA to issue certificates with indefinite validity periods.
- D. Set the subordinate CA certificate as the default routing certificate for all network traffic.
Answer: A
Explanation:
When implementing a new self-signed root certificate authority (CA) for SSL decryption on a Palo Alto Networks firewall, the subordinate CA certificate (which is generated by the firewall) must be imported into the trust stores of all client devices. This ensures that client devices trust the firewall as a valid certificate authority, enabling the firewall to decrypt and re-encrypt SSL traffic.
Importing the subordinate CA certificate into the client devices' trust stores is necessary for those devices to trust the new self-signed root CA and properly handle SSL decryption traffic.
NEW QUESTION # 25
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 Next-Generation Firewalls as normal and install the User-ID agent.
- C. Deploy the Advanced URL Filtering license and captive portal.
- D. Deploy the transparent proxy with Web Cache Communications Protocol (WCCP).
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.
