All in all, the PCNSE exam topics are highlighted as the following:

• Configuration Troubleshooting (18%)

  This section evaluates the students’ ability to identify operation and traffic problems utilizing the CLI devices and web interface, give a session production, recognize the configuration elements used to implement packet capture, and identify problems by the certificate chain of trust. They should know how to observe GlobalProtect troubleshooting information, resolve when an SD-WAN path has failed, and sort out SSL decoding failures. Furthermore, they need to know how to solve and configure interface elements, determine traffic routing concerns, and identify ACC chart activities.

• Core Concepts (23%)

  This is the last objective of the exam that measures your expertise in identifying the exact position of policy measuring according to the packet flow architecture as well as identifying the major functions staying on the management level and data level of Palo Alto Networks Firewall. It is required to identify the proper PaloAlto Networks threat preventive element to stop or decrease the attack and recognize the proper Palo Alto Networks threat interception component to stop or decrease the attack with the help of a given scenario toward firewall resources.

  The candidates need to express their ability to identify the methods for classifying users, dependencies for completing MFA, and techniques for simplifying the configuration of a firewall. They have to know how to define the policies and relevant objects, forward traffic, and control bandwidth utilization on a per-application basis with a given scenario. Also, their skills in defining the pros & cons of using distributed networking with SD-WAN and identifying how the Panorama commit recovery feature functions are tested as well.

• Plan (16%)

  The questions from this domain validate the students’ ability to identify the notions, such as how the Palo Alto Networks products operate mutually to recognize and stop threats and how to utilize template stacks & design group hierarchy for operating Palo Alto Networks firewalls as a scalable resolution with the help of Panorama. In addition, they have to distinguish the relevant interface model and arrangement for specified system positioning as well as approaches for maintaining logs utilizing Distributed Log Collection. Planning considerations unusual to extending Palo Alto Networks firewalls in hybrid, public, and private Clouds is another ability that they should possess.

  The test takers should ascertain opinions for authorization, device administration, and authentication, as well as methods of authentication production on the firewall. It is important to have knowledge of the alternatives eligible in the firewall to maintain progressive routing, decryption deployment strategies, ways of the User-ID redistribution, and advantages of adopting dynamic user groups in policy rules. It is advisable to recognize the items for which you must plan when deploying SD-WAN, VM-Series bootstrap components and their function, and the influence of utilization override to the general functions of the firewall.

• Operate (20%)

  The topic requires that the learners have the skills in identifying problems for defining visible log forwarding as well as interpreting reports, log files, and graphs to manage exchange and threat trends. Being able to identify situations that have a profit from utilizing custom signatures and the manner to update a Palo Alto Networks system to the newest version of software is also essential for an individual.

  You have to know how arrangement management procedures are applied to assure aspired operational state of stability & continuity and how to develop the firewall to mix with AutoFocus & confirm its functions. Additionally, this part validates one’s understanding of the correlation within Panorama and tools as concerning active updates versions and system implementation and/or HA equals, the roots of information that pertain to HA functionality, as well as the settings related to critical HA functions.

• Deploy and Configure (23%)

  This subject area measures the applicants’ knowledge of identifying the application purposes in Traffic log, connection within URL filtering and certification theft prevention, and production of safety rules to perform App-ID without depending on port-based practices. A potential candidate has to know about the expected settings and actions essential to deploy and plan a next-generation firewall and various techniques for authorization, authentication, and device management in PAN-OS software for relating to the firewall.

  Moreover, the examinees have to know how to design a virtual router, interface as a DHCP relay agent, frames for site-to-site VPN & GlobalProtect, characteristics of NAT system rules, VM-Series firewalls for implementation, and firewalls to utilize tags and filtered log sending for combination by system automation. Besides that, it is important to configure and maintain the certificates to verify the firewall features, identify the peculiarities that support IPv6, as well as implement and maintain the App-ID adoption, among others.

Conclusion

There’s no arguing that the PCNSE exam and certification will be great for you and your career in IT. Choose your learning materials wisely to ensure your success in the official test, particularly if you’re a beginner. Reading sub-par learning materials is going to prove to be a giant waste of time.

E: For firewalls without dedicated HA ports, select two data interfaces for the HA2 link and the backup HA1 link. Then, use an Ethernet cable to connect these in-band HA interfaces across both firewalls.
Use the management port for the HA1 link and ensure that the management ports can connect to each other across your network.

1. In Device > High Availability > General, edit the Control Link (HA1) section.
2. Select the interface that you have cabled for use as the HA1 link in the Port drop down menu.
Set the IP address and netmask. Enter a Gateway IP address only if the HA1 interfaces are on separate subnets. Do not add a gateway if the devices are directly connected.

NO.210 How is the Forward Untrust Certificate used?

 It issues certificates encountered on the Untrust security zone when clients attempt to connect to a site that has be decrypted/

 It is used when web servers request a client certificate.

 It is presented to clients when the server they are connecting to is signed by a certificate authority that is not trusted by firewall.

 It is used for Captive Portal to identify unknown users.

Though a single certificate can be used for both Forward Trust and Forward Untrust, creating a separate certificate specifically for Untrust (which must be generated as a CA) allows for easy differentiation of a valid certificate/trust error as the Palo Alto Networks device proxies the secure session.
Verify the CA to be blocked, keeping in mind that doing so blocks access to all sites issued by this CA.
