Check the PSE-SoftwareFirewall Exam Topics and Check the Test Questions

Hello everyone, welcome to today's video. We are going to talk about the key concept of the PSE-SoftwareFirewall exam. The PSE-SoftwareFirewall exam mainly covers various aspects of network security and is ideal for those who want to gain an in-depth understanding of this field. We will focus on some practical applications and common exam questions.

Okay, let’s move on to today’s topic:

1. CN-Series Firewall Traffic Security

First up, what elements does the CN-Series firewall protect? It mainly secures communication between Pods, which is essential in systems like Kubernetes. Pods are the basic units that run containers, so securing their communication is crucial to preventing internal data from being exposed to external threats.

Take a look at the test questions: 

A CN-Series firewall can secure traffic between which elements?

A. Host containers

B. Containers

C. Pods

D. Source applications

Answer: C

2. Protocol Choice in AWS Environment

Next, let's talk about protocol choices in the AWS environment. For communication between VM-Series firewalls and the gateway load balancer, we use the Geneve protocol. This protocol is very flexible and supports complex network environments, making it great for multi-tenant scenarios.

Take a look at the test questions: 

Which protocol is used for communicating between VM-Series firewalls and a gateway load balancer in Amazon Web Services (AWS)?

A. Geneve

B. VRLAN

C. VMLAN

D. GRE

Answer: A

3. Application-Level Security for AWS Web Servers

Now, let's look at how to protect web servers on AWS. VM-Series firewalls provide application-level security, including deep packet inspection and advanced threat protection. They can defend against sophisticated attacks like SQL injection and cross-site scripting, which are crucial for protecting web applications.

Take a look at the test questions: 

Which of the following can provide application-level security for a web-server instance on Amazon Web Services (AWS)?

A. VM-Series firewalls

B. Hardware firewalls

C. Terraform templates

D. Security groups

Answer: A

4. Panorama Control over NSX

Speaking of Panorama, it can control many features in NSX, such as user IP mappings, traffic steering rules, and security group assignments for virtual machines. Centralized management through Panorama makes it more efficient for network administrators to manage network environments and ensure security and isolation.

Take a look at the test questions: 

Which three NSX features can be pushed from Panorama in PAN-OS? (Choose three.)

A. Multiple authorization codes

B. User IP mappings

C. Steering rules

D. Security group assignment of virtual machines (VMs)

D. Security groups

Answer: B, C, D

5. High Availability (HA) Trigger Mechanisms

High availability is a critical concept in enterprise applications. In this section, we discussed two common mechanisms for triggering HA failovers: Ping monitoring and link monitoring. They monitor the connectivity of critical devices and the status of links to ensure continuous system availability.

Take a look at the test questions: 

Which two mechanisms could trigger a high availability (HA) failover event? (Choose two.)

A. Ping monitoring

B. Link monitoring

C. Session polling

D. Heartbeat polling

Answer: A, B

6. HA Deployment Requirements for VM-Series Firewalls

Next, let's look at the requirements for deploying high availability architectures for VM-Series firewalls. First, all devices must have the same licenses and subscriptions. Second, they must be deployed on the same type of hypervisor. This ensures seamless switching to a backup device in the event of a failure.

Take a look at the test questions: 

Which two criteria are required to deploy VM-Series firewalls in high availability (HA)? (Choose two.)

A. Configuration of asymmetric routing

B. Assignment of identical licenses and subscriptions

C. Deployment on a different host

D. Deployment on same type of hypervisor

Answer: B, D

7. Deployment Steps for VM-Series Firewall in NSX

Deploying VM-Series firewalls in NSX involves several key steps. First, you need to enable communication between Panorama and NSX Manager for centralized management of firewall policies. Then, register the VM-Series firewall as a service to integrate with other services in the NSX environment.

Take a look at the test questions: 

Which two steps are involved in deployment of a VM-Series firewall on NSX? (Choose two.)

A. Create a virtual data center (vDC) and a vApp that includes the VM-Series firewall.

B. Enable communication between Panorama and the NSX Manager.

C. Register the VM-Series firewall as a service.

D. Obtain the Amazon Machine Images (AMIs) from marketplace.

Answer: B, C

8. Supported Environments for CN-Series Firewall

Lastly, let's talk about the environments supported by the CN-Series firewall. It supports container orchestration platforms like OpenShift and Native K8, which are commonly used in modern microservices architectures. CN-Series firewalls provide comprehensive security in these environments.

Take a look at the test questions: 

What are two environments supported by the CN-Series firewall? (Choose two.)

A. OpenShift

B. Positive K

C. Native K8

D. OpenStack

Answer: A, C
