✍️ Sample PCNSE Questions & Answers

1. Which Palo Alto Networks feature enables the firewall to identify users even when they authenticate through a proxy or Citrix environment?

✓ Terminal Services Agent (TSA)

The Terminal Services Agent maps individual user traffic on shared-IP environments like Citrix or RDS by tracking port ranges assigned to each user.

2. Which zone type on a Palo Alto Networks firewall is used to inspect traffic that originates and terminates on the firewall itself?

✓ Loopback zone

The loopback zone handles traffic that originates or terminates on the firewall itself, such as management services hosted on the device.

3. What happens when a firewall running WildFire receives a 'Phishing' verdict for a submitted URL?

✓ A phishing signature is generated and distributed to WildFire subscribers

A Phishing verdict causes WildFire to generate and distribute a new anti-phishing signature to all WildFire-subscribed firewalls.

4. Which Palo Alto Networks feature provides Layer 2 segmentation by forwarding traffic based on MAC addresses without routing?

✓ Layer 2 deployment mode

Layer 2 deployment mode enables the firewall to act as a transparent bridge, forwarding traffic based on MAC addresses within the same broadcast domain.

5. What is the function of the Palo Alto Networks 'Decryption Broker' feature?

✓ It decrypts traffic and forwards plaintext copies to third-party security tools

Decryption Broker allows the firewall to decrypt SSL/TLS traffic and forward the plaintext to third-party inline security appliances for additional inspection.

6. A firewall is deployed in tap mode. Which Threat Prevention actions will be enforced on matched traffic?

✓ Only 'Alert' and 'Allow' — tap mode cannot block traffic

In tap mode, the firewall receives a copy of traffic and cannot inject packets to block or reset connections, so only passive actions like alerting are effective.
