Questions # 21:

An engineer is creating an automation workflow. The first step is to deploy a new VM-Series firewall into a VMware vSphere environment, including its virtual machine (VM) configuration and network interfaces. The second step is to connect to the firewall and configure a complex set of Security policies and objects. The team uses both Terraform and Ansible.

For which part of this workflow would Terraform typically be used?

Options:

A.

Pushing threat intelligence updates to the new firewall

B.

Deploying the VM and associated network interfaces

C.

Storing the credentials needed to access the vSphere environment

D.

Applying the detailed Security policies and objects

Questions # 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?

Options:

A.

Restarting the local firewall, running a packet capture, accessing the firewall CLI

B.

Modification of local security rules, modification of a Layer 3 interface, modification of the firewall device hostname

C.

Modification of pre-security rules, modification of a virtual router, modification of an IKE Gateway Network Profile

D.

Modification of post NAT rules, creation of new views on the local firewall ACC tab, creation of local custom reports

Questions # 23:

A network architect is planning the deployment of a new IPSec VPN tunnel to connect a local data center to a cloud environment. The plan must include all necessary Security policy configurations for both tunnel negotiation and data transit.

Which two Security policy requirements must be included in the implementation plan? (Choose two answers)

Options:

A.

The default interzone-default security policy is sufficient to allow the tunnel negotiation traffic between the firewall and the remote peer.

B.

A pair of policies is required to control the flow of data traffic into and out of the security zone assigned to the tunnel interface.

C.

A policy must explicitly permit only the IKE application between the external-facing zone and local zone.

D.

A policy must explicitly permit the IPSec container application between the external-facing zone and local zone.

Questions # 24:

Which networking technology can be configured on Layer 3 interfaces but not on Layer 2 interfaces?

Options:

A.

DDNS

B.

Link Duplex

C.

NetFlow

D.

LLDP

Questions # 25:

An engineer configures a PA-440 firewall to act as a switch by creating several Layer 2 interfaces and assigning them all to VLAN 20. A file server is connected to interface ethernet1/1, and client workstations are connected to interfaces ethernet1/2 and ethemet1/3. All devices are in VLAN 20. The clients are unable to access the file server.

Which configuration step to allow this communication by default is missing?

Options:

A.

Create an Aggregate Ethernet (AE) group that includes all three interfaces.

B.

Place ethernet1/1, ethernet1/2, and ethernet1/3 into the same Layer 2 zone.

C.

Create an "allow" Security policy with the source and destination VLAN set to "VLAN 20".

D.

Create a Layer 3 subinterface for VLAN 20 to enable routing.

Questions # 26:

An administrator is configuring a site-to-site IPSec VPN and assigns an IP address to the tunnel interface.

Which two abilities are enabled by this specific configuration step? (Choose two.)

Options:

A.

Configuring tunnel monitoring to verify the liveliness of the connection.

B.

Firewall performing NAT traversal.

C.

Running a dynamic routing protocol like OSPF over the tunnel.

D.

Firewall encrypting and decrypting packet payloads.

Questions # 27:

An engineer is troubleshooting a failed inter-VSYS communication path between a DMZ-VSYS and an Internal-VSYS. The configuration includes separate virtual routers with next-vr static routes and appropriate Security policies within each VSYS allowing traffic to and from their external zones.

Given that all routing and policy configurations within each individual VSYS are correct, what is the probable cause of the failure?

Options:

A.

The intrazone-default policy is blocking the traffic because the two external zones are logically connected.

B.

A tunnel interface is required to connect the two virtual routers instead of using the next-vr option.

C.

The administrator did not configure Visible Virtual System.

D.

The external zones were not assigned the External zone type, preventing them from connecting.

Questions # 28:

A network administrator is establishing a site-to-site VPN between a Palo Alto Networks firewall and a partner's Check Point Security Gateway. The partner has provided a specific list of local and remote IP address subnets that are permitted through the tunnel. The initial tunnel configuration on the PAN-OS firewall fails during the IKE Phase 2 exchange.

Which configuration step is essential to ensure compatibility with the policy-based Check Point gateway?

Options:

A.

Define the local and remote subnets provided by the partner in the Proxy ID settings.

B.

Create individual Security policies for each pair of local and remote subnets.

C.

Assign a specific IP address to the tunnel interface to match the Check Point gateway.

D.

Enable Dead Peer Detection (DPD) in the IKE Gateway configuration.

Questions # 29:

A Managed Security Service Provider (MSSP) is creating a new VSYS for a customer.

To prevent this customer’s traffic from overwhelming the firewall’s state table, which resource limit should the MSSP configure for the new VSYS?

Options:

A.

Max security profiles

B.

Max bandwidth

C.

Max sessions

D.

Max Log Forwarding profiles

Questions # 30:

An administrator is troubleshooting a newly configured site-to-site VPN between a PAN-OS firewall and a third-party policy-based VPN gateway. The tunnel allows traffic between the first pair of configured subnets, but traffic to a newly added remote subnet is failing. The administrator has confirmed that routing and Security policies are correct.

What is the most likely cause of this issue?

Options:

A.

A static route for the new subnet pointing to the tunnel interface is missing.

B.

The Security policy for the new subnet must be placed above the existing VPN policy.

C.

The new local and remote subnets are missing from the Proxy ID configuration.

D.

The tunnel's maximum transmission unit (MTU) size must be increased to accommodate the new traffic.
