Question 9hardmultiple choice

You are a network security engineer for a multinational corporation with users in different regions. The company uses GlobalProtect for remote access and requires multi-factor authentication (MFA) using a mobile app for all users. Recently, users in the Asia-Pacific region have reported intermittent failures when authenticating via GlobalProtect. The symptoms include: after entering credentials on the GlobalProtect portal, the authentication challenge from the MFA provider times out after 30 seconds, and the user is disconnected. Users in other regions do not experience this issue. The GlobalProtect gateways and portals are configured with Authentication Profile that uses an LDAP server for primary authentication and an MFA vendor as authentication sequence. The MFA provider sends push notifications to users' mobile devices. The firewall logs show no errors related to LDAP or MFA, but the GlobalProtect logs indicate authentication timeouts. The firewall is located in the central data center, and the MFA provider's servers are in the United States. What should you do to resolve this issue?

An organization wants to enforce multi-factor authentication (MFA) for administrative access to the Palo Alto Networks firewall. Which TWO authentication methods are supported for local administrator accounts?

Question 11hardmultiple choice

Refer to the exhibit. A firewall administrator created a local user group named 'Engineering' and added two users. However, when applying a security policy that uses this group as the source user, only one user (asmith) is matched correctly. What is the most likely cause of this issue?

Exhibit

Refer to the exhibit.

admin@PA-220> show user group name Engineering

Question 12mediummultiple choice
Read the full Securing Users and Applications with Authentication explanation →

A company uses a Palo Alto Networks firewall with Authentication Policy to enforce MFA for external users accessing a web application via GlobalProtect. The authentication sequence is set to 'PingID, LDAP'. Recently, users report that after entering their LDAP credentials, they are not prompted for PingID MFA and are allowed access immediately. The firewall logs show that the authentication policy is hit and the authentication method used is 'LDAP' only. The PingID service is reachable from the firewall. The administrator checks the Authentication Profile and sees that PingID is configured correctly. What is the most likely cause of this issue?
