Question 1:

During the process of developing a decryption strategy and evaluating which websites are required for corporate users to access, several sites have been identified that cannot be decrypted due to technical reasons. In this case, the technical reason is unsupported ciphers. Traffic to these sites will therefore be blocked if decrypted.

How should the engineer proceed?

A. Allow the firewall to block the sites to improve the security posture

B. Add the sites to the SSL Decryption Exclusion list to exempt them from decryption

C. Install the unsupported cipher into the firewall to allow the sites to be decrypted

D. Create a Security policy to allow access to those sites

Correct Answer: B

https://docs.paloaltonetworks.com/pan-os/10-2/pan-os-admin/decryption/decryption-exclusions Traffic that breaks decryption for technical reasons, such as using a pinned certificate, an incomplete certificate chain, unsupported ciphers, or mutual authentication (attempting to decrypt the traffic results in blocking the traffic). Palo Alto Networks provides a predefined SSL Decryption Exclusion list (DeviceCertificate ManagementSSL Decryption Exclusion) that excludes hosts with applications and services that are known to break decryption technically from SSL Decryption by default. If you encounter sites that break decryption technically and are not on the SSL Decryption Exclusion list, you can add them to list manually by server hostname. The firewall blocks sites whose applications and services break decryption technically unless you add them to the SSL Decryption Exclusion list.


Question 2:

An administrator creates a custom application containing Layer 7 signatures. The latest application and threat dynamic update is downloaded to the same NGFW. The update contains an application that matches the same traffic signatures as the custom application.

Which application should be used to identify traffic traversing the NGFW?

A. Custom application

B. System logs show an application error and neither signature is used.

C. Downloaded application

D. Custom and downloaded application signature files are merged and both are used

Correct Answer: C


Question 3:

An enterprise has a large Palo Alto Networks footprint that includes onsite firewalls and Prisma Access for mobile users, which is managed by Panorama The enterprise already uses GlobalProtect with SAML authentication to obtain iP-touser mapping information.

However information Security wants to use this information in Prisma Access for policy enforcement based on group mapping Information Security uses on-prermses Active Directory (AD) but is uncertain about what is needed for Prisma Access to learn groups from AD.

How can portaes based on group mapping be learned and enforced in Prisma Access?

A. Configure Prisma Access to learn group mapping via SAML assertion

B. Assign a master device in Panorama through which Prisma Access learns groups

C. Set up group mapping redistribution between an onsite Palo Alto Networks firewall and Prisma Access

D. Create a group mapping configuration that references an LDAP profile that points to on- premises domain controllers

Correct Answer: B

Step 3: Allow Panorama to use group mappings in security policies by configuring one or more next-generation on-premises or VM-series firewalls as a Master Device. If you don\’t configure a Master Device with a Prisma Access User-ID deployment, use long-form distributed name (DN) entries instead. https://docs.paloaltonetworks.com/prisma/prisma-access/prisma-access-panorama- admin/configure-user-based-policies-with-prisma-access/configure-user-id-in-prismaaccess.html


Question 4:

Which two profiles should be configured when sharing tags from threat logs with a remote User-ID agent? (Choose two.)

A. Log Ingestion

B. HTTP

C. Log Forwarding

D. LDAP

Correct Answer: BC

Threat logs, create a log forwarding profile to define how you want the firewall or Panorama to handle logs. Configure an HTTP server profile to forward logs to a remote User-ID agent. Select the log forwarding profile you created then select this server profile as the HTTP server profile https://docs.paloaltonetworks.com/pan-os/11-0/pan-os-admin/policy/use-auto-tagging-to-automate-security-actions


Question 5:

A Panorama administrator configures a new zone and uses the zone in a new Security policy.

After the administrator commits the configuration to Panorama, which device-group commit push operation should the administrator use to ensure that the push is successful?

A. force template values

B. merge with candidate config

C. specify the template as a reference template

D. include device and network templates

Correct Answer: D


Question 6:

A standalone firewall with local objects and policies needs to be migrated into Panorama. What procedure should you use so Panorama is fully managing the firewall?

A. Use the “import Panorama configuration snapshot” operation, then perform a device- group commit push with “include device and network templates”

B. Use the “import device configuration to Panorama” operation, then “export or push device config bundle” to push the configuration

C. Use the “import Panorama configuration snapshot” operation, then “export or push device config bundle” to push the configuration

D. Use the “import device configuration to Panorama” operation, then perform a device- group commit push with “include device and network templates”

Correct Answer: B

Question 7:

Which CLI command enables an administrator to view details about the firewall including uptime, PAN-OS?version, and serial number?

A. debug system details

B. show session info

C. show system info

D. show system details

Correct Answer: C

Question 8:

In a template you can configure which two objects? (Choose two.)

A. SD WAN path quality profile

B. application group

C. IPsec tunnel

D. Monitor profile

Correct Answer: CD


Question 9:

An administrator is configuring SSL decryption and needs 10 ensure that all certificates for both SSL Inbound inspection and SSL Forward Proxy are installed properly on the firewall. When certificates are being imported to the firewall for these purposes, which three certificates require a private key? (Choose three.)

A. Forward Untrust certificate

B. Forward Trust certificate

C. Enterprise Root CA certificate

D. End-entity (leaf) certificate

E. Intermediate certificate(s)

Correct Answer: ABD


Question 10:

To more easily reuse templates and template slacks , you can create term plate variables in place of firewall-specific and appliance-specific IP literals in your configurations.

Which one is the correct configuration?

A. @Panorama

B. #Pancrama

C. andPanorama

D. $Panorama

Correct Answer: D

Create a template and template stack using a variable name for an object. Variable names must start with the dollar sign ( “$” ) symbol. For example, you could use $Panorama as a variable for the Panorama IP address that you want to configure on multiple managed firewalls and appliances https://docs.paloaltonetworks.com/pan-os/8-1/pan-os-new-features/panorama- features/configuration-reusability-for-templates-and-template-stacks.html


Question 11:

An administrator wants to grant read-only access to all firewall settings, except administrator accounts, to a new-hire colleague in the IT department. Which dynamic role does the administrator assign to the new-hire colleague?

A. Device administrator (read-only)

B. System administrator (read-only)

C. Firewall administrator (read-only)

D. Superuser (read-only)

Correct Answer: A


Question 12:

A. Show vpn tunnel name | match encap

B. Show vpn flow name

C. Show running tunnel flow lookup

D. Show vpn ipsec-sa tunnel

Correct Answer: B


Question 13:

If an administrator wants to decrypt SMTP traffic and possesses the server\’s certificate, which SSL decryption mode will allow the Palo Alto Networks NGFW to inspect traffic to the server?

A. TLS Bidirectional Inspection

B. SSL Inbound Inspection

C. SSH Forward Proxy

D. SMTP Inbound Decryption

Correct Answer: B

Reference: https://www.paloaltonetworks.com/documentation/71/pan-os/pan- os/decryption/configure-ssl-inbound-inspection

1.

SSL Forward Proxy – Inside to Outside (To the the internet)

2.

SSL Inbound Proxy – Outside to Inside (usually towards a hosted webserver in your net)

3.

SSH Forward Proxy – As is states, for SSH traffic. The important one to remember for this type of decryption is that no certs are required.

B. unsupported ciphers

C. certificate pinning

D. unsupported browser version
