Question 1

An administrator creates a new security policy rule to allow HTTPS traffic from the trust zone to the untrust zone. The rule is placed at the bottom of the rule base, below an existing deny-all rule. Users report they cannot browse the internet. What is the cause?

  1. The HTTPS service must be explicitly defined in the service configuration before traffic can be allowed
  2. The trust zone interface binding is incorrectly configured for outbound traffic
  3. The deny-all rule above matches the traffic first, so the new allow rule is never evaluated
  4. The application signature for HTTPS traffic requires manual installation from the content update
Show answer & explanation

Correct answer: C - The deny-all rule above matches the traffic first, so the new allow rule is never evaluated

Question 2

An administrator configures SSL Forward Proxy decryption, but users report certificate warning messages when accessing HTTPS websites. What is the MOST likely cause?

  1. The firewall's Forward Trust CA certificate is not installed in the users' trusted certificate store
  2. The firewall's Forward Trust CA certificate has expired and needs to be renewed
  3. The firewall's Forward Trust CA certificate is using an unsupported encryption algorithm
  4. The firewall's Forward Trust CA certificate chain is incomplete or corrupted
Show answer & explanation

Correct answer: A - The firewall's Forward Trust CA certificate is not installed in the users' trusted certificate store

Question 3

A malware author creates a file that appears benign during static analysis by obfuscating its code. The malicious payload only decrypts and executes in memory at runtime. Which WildFire analysis method is specifically designed to catch this type of evasion?

  1. Static Analysis
  2. Dynamic Behavioral Analysis
  3. Runtime Memory Analysis
  4. Signature-based Detection
Show answer & explanation

Correct answer: C - Runtime Memory Analysis

Question 4

An administrator enables DNS sinkholing. An infected workstation queries DNS for a known C2 domain. What is the sequence of events?

  1. The workstation is automatically quarantined from the network
  2. The DNS query is blocked and the workstation gets no response
  3. The DNS query is forwarded to the real C2 server
  4. The firewall returns a sinkhole IP and logs the connection attempt
Show answer & explanation

Correct answer: D - The firewall returns a sinkhole IP and logs the connection attempt

Question 5

An ION device monitors three WAN links: MPLS, broadband, and LTE. The MPLS link's latency exceeds the SLA threshold for a voice application. What happens?

  1. The voice traffic is load-balanced across all three links to distribute the latency impact
  2. The ION device steers the voice traffic to the next best-performing link that meets the application SLA
  3. The ION device marks the voice packets with higher QoS priority and retries the MPLS link
  4. The voice traffic is buffered temporarily while the ION device attempts to renegotiate the MPLS SLA
Show answer & explanation

Correct answer: B - The ION device steers the voice traffic to the next best-performing link that meets the application SLA

Question 6

Panorama is running PAN-OS 11.0. An administrator wants to upgrade a managed firewall to PAN-OS 11.1. What must be done FIRST?

  1. Upgrade Panorama to PAN-OS 11.1 or newer first
  2. Upgrade the managed firewall directly
  3. Downgrade the managed firewall to 10.2 first
  4. Disconnect the firewall from Panorama before upgrading
Show answer & explanation

Correct answer: A - Upgrade Panorama to PAN-OS 11.1 or newer first

Question 7

An administrator deploys a new security rule to block a specific application. After committing, the application is still accessible for existing sessions. Why?

  1. The commit failed silently and needs to be retried
  2. The application is exempted from security policy enforcement
  3. The firewall needs a reboot to enforce new security rules
  4. Existing sessions continue under the original policy until timeout or reset
Show answer & explanation

Correct answer: D - Existing sessions continue under the original policy until timeout or reset

Question 8

The complete policy evaluation order on a Panorama-managed firewall is:

  1. Pre-Rules → Post-Rules → Local Rules → Default Rules
  2. Pre-Rules → Local Rules → Post-Rules → Default Rules
  3. Local Rules → Pre-Rules → Post-Rules → Default Rules
  4. Default Rules → Local Rules → Pre-Rules → Post-Rules
Show answer & explanation

Correct answer: B - Pre-Rules → Local Rules → Post-Rules → Default Rules

Question 9

A site-to-site VPN completes Phase 1 successfully, but Phase 2 fails. What is the MOST likely cause?

  1. The VPN license has expired on one of the peers during tunnel establishment
  2. Pre-shared key mismatch between the two peers causing authentication failure
  3. Proxy ID mismatch between the two peers, or mismatched Phase 2 encryption/hash proposals
  4. Incorrect management IP address configuration on the remote peer device
Show answer & explanation

Correct answer: C - Proxy ID mismatch between the two peers, or mismatched Phase 2 encryption/hash proposals

Question 10

An administrator creates a HIP object that checks if 'Disk Encryption is enabled.' This HIP object is added to a HIP profile, which is referenced in a security policy. A user connects via GlobalProtect with disk encryption disabled. What happens?

  1. The security policy using the HIP profile does not match the user's traffic
  2. The user connects normally with full access
  3. The user's disk is automatically encrypted by the firewall
  4. The user receives limited network access with restricted applications
Show answer & explanation

Correct answer: A - The security policy using the HIP profile does not match the user's traffic
