NEW QUESTION # 108
An enterprise network security team is deploying VM-Series firewalls in a multi-cloud environment. Some firewalls are deployed in VMware NSX-V, while others are in AWS, and all are centrally managed using Panorama with the appropriate plugins installed. The team wants to streamline policy management by organizing the firewalls into device groups in which the AWS-based firewalls act as a parent device group, while the NSX-V firewalls are configured as a child device group to inherit Security policies. However, after configuring the device group hierarchy and attempting to push configurations, the team receives errors, and policy inheritance is not functioning as expected. What is the most likely cause of this issue?
- A. Panorama must use the same plugin version numbers for both AWS and NSX-V environments before device group inheritance can function properly
- B. Panorama does not support policy inheritance across device groups containing firewalls deployed in different hypervisors when using multiple plugins
- C. Panorama requires the objects to be overridden in the child device group before firewalls in different hypervisors can inherit Security policies
- D. Panorama by default does not allow different hypervisors in parent/child device groups, but this can be overridden with the command "set device-group allow-multi-hypervisor enable"
Answer: B
Explanation:
Panorama's device group hierarchy supports policy inheritance, but it does not support inheritance across groups with firewalls on different hypervisors (e.g., AWS and NSX-V) when managed by multiple plugins (Option D). AWS and NSX-V firewalls use distinct plugins (e.g., AWS Plugin, NSX Plugin), and Panorama restricts cross-hypervisor inheritance due to differing configurations and contexts, causing errors when pushing policies.

NEW QUESTION # 111
What would allow a network security administrator to authenticate and identify a user with a new BYOD-type device that is not joined to the corporate domain?
- A. an Authentication policy with 'unknown' selected in the Source User field
- B. a Security policy with 'unknown' selected in the Source User field
- C. a Security policy with 'known-user' selected in the Source User field
- D. an Authentication policy with 'known-user' selected in the Source User field
Answer: A
Explanation:
For a network security administrator to authenticate and identify a user with a new BYOD-type device that is not joined to the corporate domain, the most effective method is to use an Authentication policy targeting users not yet identified by the system.
A: an Authentication policy with 'unknown' selected in the Source User field:
* An Authentication policy allows the firewall to challenge unidentified users for credentials. By selecting
'unknown' in the Source User field, the policy targets users who have not yet been identified by the firewall, which would include users on new BYOD devices not joined to the domain.
* Once the user provides valid credentials, the firewall can authenticate the user and map their identity to subsequent sessions, enabling the application of user-based policy rules and monitoring.
This approach ensures that new and unknown devices can be properly authenticated and identified without compromising security or requiring the device to be part of the corporate domain.
