PCNSE Network Segmentation and Zone Security 2

Question 1

What is the purpose of a Virtual Wire (vwire) deployment mode in Palo Alto Networks?

Accepted Answer

To insert the firewall transparently into an existing network segment without IP addressing changes

Answer

Virtual Wire mode inserts the firewall transparently between two network points without requiring IP address changes, making it easy to deploy inline without network redesign.

Question 2

Which Palo Alto Networks feature uses tags to dynamically update security policy membership based on VM or workload attributes?

Accepted Answer

Dynamic Address Groups (DAG)

Answer

Dynamic Address Groups automatically update their membership based on tags registered by VM monitoring or the XML API, enabling policy that follows workloads in dynamic cloud environments.

Question 3

In a multi-vsys Palo Alto firewall, what is the function of a Virtual System (vsys)?

Accepted Answer

To create separate, isolated firewall instances on a single physical device

Answer

Virtual Systems allow a single Palo Alto firewall to operate as multiple independent logical firewalls, each with its own zones, policies, and administrators.

Question 4

What is the primary security benefit of micro-segmentation in a data center environment?

Accepted Answer

It limits lateral movement by isolating workloads and applying policy between them

Answer

Micro-segmentation prevents attackers from moving laterally between workloads by enforcing security policies on east-west traffic between individual servers or VMs.

Question 5

Which Palo Alto Networks feature provides packet buffer protection against single-session flood attacks that bypass rate limiting?

Accepted Answer

Zone Protection Profile - Packet Buffer Protection

Answer

Packet Buffer Protection in Zone Protection Profiles detects and mitigates attacks that consume firewall packet buffer resources, even from a single session, protecting against buffer exhaustion.
