Paloalto Networks Updated PSE-Strata Exam Questions and Answers by bryson

For detecting actionable events on the network and processing related threat events, the Automated Correlation Engine (ACE) in PAN-OS is highly suitable.

Automated Correlation Engine (ACE):

ACE analyzes firewall logs to detect patterns and sequences of events that may indicate a compromised host.

It automatically processes related threat events, pinpointing areas of risk and providing actionable insights.

Dynamic user groups (DUGs) provide flexibility in managing user access and security policies.

Tagging Users via Panorama or Web UI (Option B):

Administrators can manually add or remove users from DUGs using the graphical interface provided by Panorama or the firewall’s Web UI.

In the context of XYZ Corporation's legacy environment with asymmetric routing, enabling redundancy while supporting asymmetric routing can be effectively managed with Palo Alto Networks firewalls. Asymmetric routing occurs when the path the traffic takes to reach a destination is different from the path it takes to return. To handle this scenario, the following two features must be enabled:

HA Active/Active (B): High Availability (HA) in an active/active configuration allows both firewalls in the pair to process traffic simultaneously. This is essential for handling asymmetric routing as both firewalls can process and route packets independently, ensuring that the traffic can flow correctly even if it comes back via a different path.

Policy-Based Forwarding (D): Policy-Based Forwarding (PBF) enables the firewall to make routing decisions based on policies that match traffic to specific interfaces, rather than relying solely on the routing table. This is crucial for asymmetric routing because it allows the firewall to direct return traffic along a specific path, aligning with the asymmetric nature of the traffic flow.

File Blocking Profiles can help prevent drive-by downloads by blocking certain types of file downloads that are commonly associated with malware. This allows web-browsing traffic to continue but prevents potentially harmful files from being downloaded automatically, thus protecting against malicious software that could be installed without user consent.
