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?
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.
What are two valid zone types that can be selected from the zone configuration menu, per Palo Alto Networks best practices? (Choose two answers)
In the Palo Alto Networks PAN-OS environment, a Security Zone is a logical grouping of interfaces that allows for the application of security policies based on the network's topology and security requirements. When navigating to the zone configuration menu, an administrator must define the Type of the zone, which dictates how the firewall processes traffic and which types of interfaces can be associated with it.
The primary valid zone types available in the configuration menu include Layer 3, Layer 2, Virtual Wire, Tap, and Tunnel.
Layer 3 (Option A): This is the most common zone type. It is used when the firewall acts as a routing hop. Interfaces in a Layer 3 zone have IP addresses assigned and participate in routing tables.
Layer 2 (Option B): This type is used when the firewall is integrated into a switched environment where it performs inspection without acting as a router. Traffic is switched between interfaces within the same Layer 2 zone based on MAC addresses.
It is important to note that while Management and DMZ are common terms in networking, they are not technical 'types' in the zone configuration menu. 'Management' refers to a dedicated physical port for administrative access (which typically does not belong to a security zone for transit traffic), and 'DMZ' is a functional role or name given to a zone (usually of the Layer 3 type) rather than a selectable architectural type.
Which type of firewall resource can be assigned when configuring a new firewall virtual system (VSYS)?
When configuring a new firewall virtual system (VSYS) on a Palo Alto Networks firewall, one of the resources that can be assigned is the sessions limit. This setting allows the administrator to control the number of active sessions that can be handled by the VSYS, ensuring that each virtual system has an appropriate allocation of resources based on its needs.
Which statement applies to Log Collector Groups?
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.
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?
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.
