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

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?

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

will be denied because intra-zone traffic is denied.

Which option will ensure that no single administrator's changes are interrupted or
undone by another administrator while still allowing all administrators to complete their
changes prior to issuing a commit? Correct answer- Each administrator sets a
configuration and commit lock for the vsys to which they are making changes.
A Palo Alto Networks firewall is being targeted by a DoS attack from the Internet that is
creating a flood of bogus TCP connections to internal servers behind the firewall. This
