QuestionQ1

VerifiedPAN-OS Networking Configuration

In an active/active high-availability (HA) deployment using two PA-Series firewalls, how is the HA3 interface used by the firewalls?

Explanation

In active/active HA, the HA3 link enables a firewall to forward packets to its HA peer for session setup and for processing asymmetrically routed traffic, including Layer 7 inspection. HA1 is the control link, HA2 carries state synchronization, and HA4 is used for session-cache synchronization among cluster members.

QuestionQ2

VerifiedPAN-OS Networking Configuration

While upgrading routing infrastructure in a customer environment, a network administrator plans to implement the Advanced Routing Engine (ARE) on a Palo Alto Networks firewall.

Which firewall models support this configuration?

Choose three
Explanation

The Advanced Routing Engine is supported on PA-7000, PA-5400, PA-5200, PA-3200, PA-1400, and PA-400 Series firewalls, as well as VM-Series and CN-Series firewalls. Accordingly, the model groups in A, B, and D are supported. PA-850 is not included in the supported-platform list, so C is not valid.

QuestionQ3

VerifiedPAN-OS Networking Configuration

An organization is deploying VM-Series firewalls in Microsoft Azure to protect its VNets. A key requirement is for the security infrastructure to withstand the failure of an entire Azure Availability Zone.

What is the recommended approach to meet this objective?

Explanation

Deploying independent VM-Series firewalls in separate Availability Zones behind an Azure Load Balancer provides resilience to an Availability Zone outage. The load balancer health-checks the instances and distributes traffic only to healthy firewalls, so loss of one zone does not eliminate the security path.

QuestionQ4

VerifiedPAN-OS Networking Configuration

When configuring a Zone Protection profile, under which section (protection type) would an NGFW engineer set options to defend against activities such as spoofed IP addresses and split-handshake session-establishment attempts?

Explanation

Packet-Based Attack Protection includes IP Drop settings for spoofed IP addresses and TCP Drop settings for Split Handshake, which enforces the standard TCP three-way handshake.

QuestionQ5

VerifiedPAN-OS Networking Configuration

Which feature can be enabled on a Layer 3 interface but is unavailable on Layer 2 interfaces?

Explanation

A DHCP client is configured on a Layer 3 interface to obtain a dynamically assigned IPv4 address. Layer 2 interfaces do not provide this Layer 3 IP-addressing function. NetFlow and LLDP can be used with Layer 2 interfaces as well.
