Introduction to Palo Alto Networks Certified Network Security Engineer PCNSE Exam

Palo Alto firewalls are Next Generation firewalls built from the ground up to address legacy firewalls issues. PCNSE exam dumps are a great way to start the Palo Alto Networks Certified Network Security Engineer (PCNSE PAN-OS) preparation by properly following and understanding each topic in the exam topics. PCNSE practice exams follows the syllabus in the Palo Alto and describe each topic to pass the exam the first time you take it. Also, the PCNSE practice test concentrates on the “learn by doing”, therefore, it is an exam with a lot of labs and configuration. Not just boring Power Points presentations. This guide is an instrument to get you on the same page with Palo Alto and understand the nature of the Palo Alto PCNSE exam.

The PCNSE exam should be taken by anyone who wishes to demonstrate a deep understanding of Palo Alto Networks technologies, including customers who use Palo Alto Networks products, value-added resellers, pre-sales system engineers, system integrators, and support staff.

QUESTION 20
Which three authentication services can administrator use to authenticate admins into the Palo Alto Networks NGFW without defining a corresponding admin account on the local firewall? (Choose three.)

 Kerberos

 PAP

 SAML

 TACACS+

 RADIUS

 LDAP

https://docs.paloaltonetworks.com/pan-os/8-0/pan-os-admin/firewall-administration/manage-firewall-administrators/administrative-authentication The administrative accounts are defined on an external SAML, TACACS+, or RADIUS server. The server performs both authentication and authorization. For authorization, you define Vendor-Specific Attributes (VSAs) on the TACACS+ or RADIUS server, or SAML attributes on the SAML server. PAN-OS maps the attributes to administrator roles, access domains, user groups, and virtual systems that you define on the firewall. For details, see:
Configure SAML Authentication Configure TACACS+ Authentication Configure RADIUS Authentication

QUESTION 21
An engineer is planning an SSL decryption implementation.
Which of the following statements is a best practice for SSL decryption?

 Obtain an enterprise CA-signed certificate for the Forward Trust certificate

 Obtain a certificate from a publicly trusted root CA for the Forward Trust certificate

 Use an enterprise CA-signed certificate for the Forward Untrust certificate

 Use the same Forward Trust certificate on all firewalls in the network

Enterprise CA-signed Certificates-An enterprise CA can issue a signing certificate that the firewall can use to sign the certificates for sites which require SSL decryption. When the firewall trusts the CA that signed the certificate of the destination server, the firewall can send a copy of the destination server certificate to the client, signed by the enterprise CA. This is a best practice because usually all network devices already trust the Enterprise CA (it is usually already installed in the devices’ CA Trust storage), so you don’t need to deploy the certificate on the endpoints, so the rollout process is smoother.

QUESTION 22
Which is not a valid reason for receiving a decrypt-cert-validation error?

 Unsupported HSM

 Unknown certificate status

 Client authentication

 Untrusted issuer

Explanation
Per the link
https://docs.paloaltonetworks.com/pan-os/7-1/pan-os-new-features/networking-features/ssl-ssh-session-end-reaso
, receiving the decrypt-cert-validation error is valid for the following conditions: expired, untrusted issuer, unknown status, or status verification time-out. “Unsupported HSM” is not a valid reason for receiving a decrypt-cert-validation error.

QUESTION 23
A network Administrator needs to view the default action for a specific spyware signature. The administrator follows the tabs and menus through Objects> Security Profiles> Anti-Spyware and select default profile.
What should be done next?

 Click the simple-critical rule and then click the

 Click the Exceptions tab and then click

 View the default actions displayed in the Action column.

QUESTION 24
Which data flow describes redistribution of user mappings?

 User-ID agent to firewall

 Domain Controller to User-ID agent

 User-ID agent to Panorama

 firewall to firewall

QUESTION 25
Which User-ID method maps IP addresses to usernames for users connecting through an 802.1x-enabled wireless network device that has no native integration with PAN-OS® software?

 XML API

 Port Mapping

 Client Probing

 Server Monitoring

Explanation/Reference:
Explanation:
Captive Portal and the other standard user mapping methods might not work for certain types of user access. For example, the standard methods cannot add mappings of users connecting from a third-party VPN solution or users connecting to a 802.1x-enabled wireless network. For such cases, you can use the PAN-OS XML API to capture login events and send them to the PAN-OS integrated User-ID agent Reference: https://www.paloaltonetworks.com/documentation/71/pan-os/pan-os/user-id/user-id-concepts

QUESTION 26
What are two prerequisites for configuring a pair of Palo Alto Networks firewalls in an active/passive High Availability (HA) pair? (Choose two.)

 The management interfaces must be on the same network.

 The firewalls must have the same set of licenses.

 The peer HA1 IP address must be the same on both firewalls.

 HA1 should be connected to HA1, either directly or with an intermediate Layer 2 device.

To set up high availability on your Palo Alto Networks firewalls, you need a pair of firewalls that meet the following requirements:
The same set of licenses –Licenses are unique to each firewall and cannot be shared between the firewalls. Therefore, you must license both firewalls identically. If both firewalls do not have an identical set of licenses, they cannot synchronize configuration information and maintain parity for a seamless failover.
The same type of interfaces –Dedicated HA links, or a combination of the management port and in-band ports that are set to interface type HA.
Determine the IP address for the HA1 (control) connection between the HA peers. The HA1 IP address for both peers must be on the same subnet if they are directly connected or are connected to the same switch.
Etc.

QUESTION 27
A company hosts a publicly accessible web server behind a Palo Alto Networks next- generation firewall with the following configuration information:
* Users outside the company are in the “Untrust-L3” zone.
* The web server physically resides in the “Trust-L3” zone.
* Web server public IP address: 23.54.6.10
* Web server private IP address: 192.168.1.10
Which two items must the NAT policy contain to allow users in the Untrust-L3 zone to access the web server? (Choose two.)

 Destination IPof 23.54.6.10

 UntrustL3 for both Source and Destination Zone

 Destination IP of 192.168.1.10

 UntrustL3 for Source Zone and Trust-L3 for Destination Zone

QUESTION 28
How can packet butter protection be configured?

 at me device level (globally to protect firewall resources and ingress zones, but not at the zone level

 at the device level (globally) and it enabled globally, at the zone level

 at the interlace level to protect firewall resources

 at zone level to protect firewall resources and ingress zones but not at the device level

QUESTION 29
A critical US-CERT notification is published regarding a newly discovered botnet. The malware is very evasive and is not reliably detected by endpoint antivirus software. Furthermore, SSL is used to tunnel malicious traffic to command-and-control servers on the internet and SSL Forward Proxy Decryption is not enabled.
Which component once enabled on a perimeter firewall will allow the identification of existing infected hosts in an environment?

 Anti-Spyware profiles applied outbound security policies with DNS Query action set to sinkhole

 File Blocking profiles applied to outbound security policies with action set to alert

 Vulnerability Protection profiles applied to outbound security policies with action set to block

 Antivirus profiles applied to outbound security policies with action set to alert

Starting with PAN-OS 6.0, DNS sinkhole is an action that can be enabled in Anti-Spyware profiles. A DNS sinkhole can be used to identify infected hosts on a protected network using DNS traffic in environments where the firewall can see the DNS query to a malicious URL.
The DNS sinkhole enables the Palo Alto Networks device to forge a response to a DNS query for a known malicious domain/URL and causes the malicious domain name to resolve to a definable IP address (fake IP) that is given to the client. If the client attempts to access the fake IP address and there is a security rule in place that blocks traffic to this IP, the information is recorded in the logs.
