A client downloads a malicious file from the internet. The Palo Alto firewall has a valid
WildFire subscription. The Security policy rule shown above matches the client HTTP session:
Which three actions take place when the firewall's Content-ID engine detects a virus in the file
and the decoder action is set to "block"? (Choose three.) - CORRECT ANSWER - A threat

A company has a pair of PA-3050s running PAN-OS 6.0.4. Antivirus, Threat Prevention, and
URL Filtering Profiles are in place and properly configured on both inbound and outbound
policies. A Security Operation Center (SOC) engineer starts his shift and faces the traffic logs
presented in the screenshot shown above. He notices that the traffic is being allowed outbound.
Which actions should the SOC engineer take to safely allow known but not yet qualified
applications, without disrupting the remaining traffic policies? - CORRECT ANSWER -
Create Application Override policies after a packet capture to identify the applications that are
triggering the "unknown-tcp". Then create new custom applications for those policies, and add
these new policies above the current policy that allows the traffic.
A company has a Palo Alto Networks firewall configured with the following three zones:
Internet DMZ Inside. All users are located on the Inside zone and are using public DNS servers
for name resolution. The company hosts a publicly accessible web application on a server in the
DMZ zone. Which NAT rule configuration will allow users on the Inside zone to access the web
application using its public IP address? - CORRECT ANSWER - Three zone U-turn NAT
A company has a Palo Alto Networks firewall configured with the following three zones:
Untrust-L3 DMZ Trust-L3. The company hosts a publicly accessible web application on a server
that resides in the Trust-L3 zone. The web server is associated with the following IP addresses:
Web Server Public IP: 2.2.2.1/24 , Web Server Private IP: 192.168.1.10/24 . The security
administrator configures the following two-zone U-Turn NAT rule to allow users using
10.10.1.0/24 on the "Trust-L3" zone to access the web server using its public IP address in the
, Untrust-L3 zone: Which statement is true in this situation? - CORRECT ANSWER - The
traffic will be considered intra-zone based on the translated destination zone.
A company is deploying a pair of PA-5060 firewalls in an environment requiring support for
asymmetric routing. Which High Availability (HA) mode best supports this design requirement?
- CORRECT ANSWER - Active-Active mode
A company policy dictates that logs must be retained in their original format for a period of time
that would exceed the space limitations of the Palo Alto Networks firewall's internal storage.
Which two options will allow the company to meet this requirement? (Choose two.) -
CORRECT ANSWER - Palo Alto Networks Log Collector
Panorama Virtual Machine with NFS storage
A company uses Active Directory and RADIUS to capture User-ID information and implement
user-based policies to control web access. Many Linux and Mac computers in the environment
that do not have IP-address-to-user mappings. What is the best way to collect user information
for those systems? - CORRECT ANSWER - Use Captive Portal to capture user
information
A company wants to run their pair of PA-200 firewalls in a High Availability active/passive
mode and will be using HA-Lite. Which capability can be used in this situation? - CORRECT
ANSWER - Configuration Sync
A Management Profile to allow SSH access has been created and applied to interface
ethernet1/1. A security rule with the action "deny" is applied to packets from "any" source zone
to "any" destination zone. What will happen when someone attempts to initiate an SSH
connection to ethernet1/1? - CORRECT ANSWER - SSH access to the interface will be
denied because intra-zone traffic is denied.
A network administrator needs to view the default action for a specific spyware signature. The
administrator follows the tabs and menus through Objects > Security Profiles > Anti-Spyware,
and selects the default Profile. What should be done next? - CORRECT ANSWER - Click
the Exceptions tab and then click Show all signatures.
