PSE-SWFW-Pro-24 Leak Questions

Dynamic Address Groups (DAGs) use tags to dynamically populate their membership.  

Why A, B, and C are correct:

A. Static tags are part of the configuration on the firewall, while dynamic tags are part of the runtime configuration:Static tags are configured directly on objects. Dynamic tags are applied based on runtime conditions (e.g., by the VMMonitoring agent or User-ID agent).  

B. Dynamic Address Groups that are referenced in Security policies must be committed on the firewall:Like any configuration change that affects security policy, changes to DAGs (including tag associations) must be committed to take effect.

C. To dynamically register tags, use either the XML API or the VM Monitoring agent on the firewall or on the User-ID agent:These are the mechanisms for dynamically applying tags based on events or conditions.

Why D and E are incorrect:

D. IP-Tag registrations to Dynamic Address Groups must be committed on the firewall after each change:While changes to theconfigurationof a DAG (like adding a new tag filter) require a commit, theregistrationof IP addresses with tags does not. The DAG membership updates dynamically as tags are applied and removed.

E. Dynamic Address Groups use tags as filtering criteria to determine their members, and filters do not use logical operators:DAG filtersdosupport logical operators (AND, OR) to create more complex membership criteria.

Palo Alto Networks References:

PAN-OS Administrator's Guide:The section on Dynamic Address Groups provides details on how they work, including the use of tags as filters and the mechanisms for dynamic tag registration.  

VM Monitoring and User-ID Agent Documentation:These documents explain how these components can be used to dynamically apply tags.

The documentation confirms the correct statements regarding static vs. dynamic tags, the need to commit DAG changes, and the methods for dynamic tag registration. It also clarifies that DAG filtersdouse logical operators and that IP-tag registrations themselves don't require commits.

The question asks about a capability common to VM-Series deployments across Azure, GCP, and AWS, as described in the "Securing Applications" design guides.

C. Horizontal scalability through cloud-native load balancers:This is the correct answer. A core concept in cloud deployments, and emphasized in the "Securing Applications" guides, is using cloud-native load balancers (like Azure Load Balancer, Google Cloud Load Balancing, and AWS Elastic Load Balancing) to distribute traffic across multiple VM-Series firewall instances. This provides horizontal scalability, high availability, and fault tolerance. This is common across all three major cloud providers.  

Why other options are incorrect:

A. BGP dynamic routing to peer with cloud and on-premises routers:While BGP is supported by VM-Series and can be used for dynamic routing in cloud environments, it is not explicitly highlighted as acommoncapability across all three clouds in the "SecuringApplications" guides. The guides focus more on the application security aspects and horizontal scaling. Also, the specific BGP configurations and integrations can differ slightly between cloud providers.

B. GlobalProtect portal and gateway services:While GlobalProtect can be used with VM-Series in cloud environments, the "Securing Applications" guides primarily focus on securing application trafficwithinthe cloud environment, not remote access. GlobalProtect is more relevant for remote user access or site-to-site VPNs, which are not the primary focus of these guides.

D. Site-to-site VPN:While VM-Series firewalls support site-to-site VPNs in all three clouds, this is not the core focus or common capability highlighted in the "Securing Applications" guides. These guides emphasize securing application traffic within the cloud using techniques like microsegmentation and horizontal scaling.

The key reference here is the "Securing Applications" design guides for VM-Series firewalls. These guides are available on the Palo Alto Networks support site (live.paloaltonetworks.com). Searching for "VM-Series Securing Applications" along with the name of the respective cloud provider (Azure, GCP, AWS) will usually provide the relevant guides
