A network administrator is configuring an Aggregate Ethernet (AE) interface on an active/passive high availability (HA) pair. To reduce network downtime during a failover, the administrator wants the passive firewall's AE interface to be fully negotiated with the switch before it becomes active. Which Link Aggregation Control Protocol (LACP) setting achieves this administrator's goal?
Correct Answer: B
Basic Concept: LACP pre-negotiation on a passive HA peer lets the aggregate interface maintain negotiation with the switch before failover. Why B is Correct: Enable in HA passive state is the specific LACP setting that reduces convergence delay after failover. Why A is Wrong: LACP Mode active is an HA-related setting or behavior, but it is not the specific HA link, LACP pre-negotiation option, or upgrade sequence required here. Why C is Wrong: System Priority: 1 is an HA-related setting or behavior, but it is not the specific HA link, LACP pre-negotiation option, or upgrade sequence required here. Why D is Wrong: Transmission Rate: fast is an HA-related setting or behavior, but it is not the specific HA link, LACP pre-negotiation option, or upgrade sequence required here.
Question 37
Which two zone types are valid when configuring a new security zone? (Choose two.)
Correct Answer: A,D
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.
Question 38
An engineer is implementing a new rollout of SAML for administrator authentication across a company's Palo Alto Networks NGFWs. User authentication on company firewalls is currently performed with RADIUS, which will remain available for six months, until it is decommissioned. The company wants both authentication types to be running in parallel during the transition to SAML. Which two actions meet the criteria? (Choose two.)
Correct Answer: B,C
B). Create an authentication sequence that orders the RADIUS profile first followed by the SAML profile, allowing the firewall to attempt RADIUS authentication and fall back to SAML if needed, supporting tandem operation for administrator logins. C). Create and apply an authentication profile using the SAML Identity Provider Server Profile, which can then be sequenced alongside the existing RADIUS profile without disrupting current authentication.
Question 39
A network security engineer at a 24/7 online retailer is upgrading an active/passive high availability (HA) cluster of PAN-OS firewalls. The primary goal is to perform the upgrade with no service interruption to online transactions. The engineer has already downloaded the new software to both devices. Which sequence of actions will meet this requirement?
Correct Answer: C
Basic Concept: For active/passive HA upgrades, the safest method is to upgrade the passive firewall first, fail over to it, then upgrade the remaining peer. This preserves forwarding during most of the process. Why C is Correct: The selected sequence keeps one firewall forwarding traffic at all times and avoids simultaneous reboots. Why A is Wrong: From Panorama, create a scheduled software update job targeting both firewalls in the HA pair to run at the same time, then rely on the HA election process to manage the failover automatically. is an HA-related setting or behavior, but it is not the specific HA link, LACP pre-negotiation option, or upgrade sequence required here. Why B is Wrong: Upgrade the passive firewall first while it is still in the passive state. Once it reboots and is operational, suspend the active firewall to fail over to the newly upgraded device. Then, upgrade the remaining firewall. is an HA-related setting or behavior, but it is not the specific HA link, LACP pre- negotiation option, or upgrade sequence required here. Why D is Wrong: Disable HA synchronization on the active firewall, upgrade the passive firewall, and then re-enable synchronization. Once synchronized, repeat the process on the other firewall. is an HA-related setting or behavior, but it is not the specific HA link, LACP pre-negotiation option, or upgrade sequence required here.
Question 40
What are two valid zone types that can be selected from the zone configuration menu, per Palo Alto Networks best practices? (Choose two answers)
Correct Answer: A,B
In the Palo Alto Networks PAN-OS environment, aSecurity Zoneis 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 theTypeof 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 includeLayer 3,Layer 2,Virtual Wire,Tap , andTunnel. * 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 whileManagementandDMZare 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.
