(Choose three.) -Answer- A threat log entry is generated. The file download is terminated. The client receives a block page. 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? -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? -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? -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? -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.) -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? -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? -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? -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? -Answer- Click the Exceptions tab and then click Show all signatures.
