Answer(s): D



SSL Forward Proxy decryption is configured, but the firewall uses Untrusted-CA to sign the website https://www.important-website.com certificate. End-users are receiving the "security certificate is not trusted" warning. Without SSL decryption, the web browser shows that the website certificate is trusted and signed by a well-known certificate chain: Well-Known-Intermediate and Well-Known-Root-CA.
The network security administrator who represents the customer requires the following two behaviors when SSL Forward Proxy is enabled:

1. End-users must not get the warning for the https://www.very-important-website.com/ website
2. End-users should get the warning for any other untrusted website

Which approach meets the two customer requirements?

  1. Clear the Forward Untrust Certificate check box on the Untrusted-CA certificate and commit the configuration
  2. Install the Well-Known-Intermediate-CA and Well-Known-Root-CA certificates on all end-user systems in the user and local computer stores
  3. Navigate to Device > Certificate Management > Certificates > Device Certificates, import Well-Known-Intermediate-CA and Well-Known-Root-CA, select the Trusted Root CA check box, and commit the configuration
  4. Navigate to Device > Certificate Management > Certificates > Default Trusted Certificate Authorities, import Well-Known-Intermediate-CA and Well-Known-Root-CA, select the Trusted Root CA check box, and commit the configuration

Answer(s): C



An administrator needs to evaluate a recent policy change that was committed and pushed to a firewall device group. How should the administrator identify the configuration changes?

  1. review the configuration logs on the Monitor tab
  2. use Test Policy Match to review the policies in Panorama
  3. context-switch to the affected firewall and use the configuration audit tool
  4. click Preview Changes under Push Scope

Answer(s): A



The administrator for a small company has recently enabled decryption on their Palo Alto Networks firewall using a self-signed root certificate. They have also created a Forward Trust and Forward Untrust certificate and set them as such.

The admin has not yet installed the root certificate onto client systems.
What effect would this have on decryption functionality?

  1. Decryption will not function because self-signed root certificates are not supported
  2. Decryption will function, but users will see certificate warnings for each SSL site they visit
  3. Decryption will not function until the certificate is installed on client systems
  4. Decryption will function, and there will be no effect to end users

Answer(s): B



A network administrator plans a Prisma Access deployment with three service connections, each with a BGP peering to a CPE. The administrator needs to minimize the BGP configuration and management overhead on on-prem network devices.

  2. summarized BGP routes before advertising
  3. default routing
  4. target service connection for traffic steering
