NEW QUESTION # 160
A firewall architect is attempting to install a new Palo Alto Networks NGFW. The company has previously had issues moving all administrative functions onto a data plane interface to meet the design limitations of the environment. The architect is able to access the device for HTTPS and SSH; however, the NGFW can neither validate licensing nor get updates. Which action taken by the architect will resolve this issue?
- A. Validate that all upstream devices will allow and properly route the outbound traffic to the external destinations needed
- B. Enable OCSP for the data plane interface so the firewall will create a certificate with the data plane interface's IP
- C. Create a service route that sets the source interface to the data plane interface in question
- D. Create a loopback from the management interface to the data plane interface, then make a service route from the management interface to the data plane interface
Answer: A
Explanation:
When administrative functions (e.g., licensing, updates) are moved to a data plane interface, the firewall uses that interface for outbound communication to Palo Alto Networks servers (e.g., licensing and update servers).
If HTTPS/SSH work but licensing/updates fail, the issue is likely upstream connectivity. Option B ensures that upstream devices (routers, firewalls) allow and route traffic to required destinations (e.g., updates.
paloaltonetworks.com) over ports like 443.
Option A (service route) assumes the interface is already set but doesn't address external routing. Option C (loopback) is unnecessary and complex. Option D (OCSP) relates to certificate validation, not licensing
/updates. Documentation emphasizes validating external connectivity.

NEW QUESTION # 162
An engineer is designing a deployment of multi-vsys firewalls.
What must be taken into consideration when designing the device group structure?
- A. Multiple vsys and firewalls can be assigned to a device group, and a multi-vsys firewall can have each vsys in a different device group.
- B. Only one vsys or one firewall can be assigned to a device group, except for a multi-vsys firewall, which must have all its vsys in a single device group.
- C. Only one vsys or one firewall can be assigned to a device group, and a multi-vsys firewall can have each vsys in a different device group.
- D. Multiple vsys and firewalls can be assigned to a device group, and a multi-vsys firewall must have all its vsys in a single device group.
Answer: A
Explanation:
Explanation
https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClETCA0 A device group is a logical grouping of firewalls that share the same security policy rules. A device group can contain multiple vsys and firewalls, including multi-vsys firewalls. A multi-vsys firewall can have each vsys in a different device group, depending on the desired security policy for each vsys. This allows for granular control and flexibility in managing multi-vsys firewalls with Panorama1.

NEW QUESTION # 166
An organization is interested in migrating from their existing web proxy architecture to the Web Proxy feature of their PAN-OS 11.0 firewalls. Currently. HTTP and SSL requests contain the c IP address of the web server and the client browser is redirected to the proxy Which PAN-OS proxy method should be configured to maintain this type of traffic flow?
- A. DNS proxy
- B. SSL forward proxy
- C. Explicit proxy
- D. Transparent proxy
Answer: D
Explanation:
Explanation
A transparent proxy is a type of web proxy that intercepts and redirects HTTP and HTTPS requests without requiring any configuration on the client browser1. The firewall acts as a gateway between the client and the web server, and performs security checks on the traffic.
A transparent proxy can be configured on PAN-OS 11.0 firewalls by performing the following steps1:
Enable Web Proxy under Device > Setup > Services
Select Transparent Proxy as the Proxy Type
Configure a Service Route for Web Proxy
Configure SSL/TLS Service Profile for Web Proxy
Configure Security Policy Rules for Web Proxy Traffic
By configuring a transparent proxy on PAN-OS 11.0 firewalls, an organization can migrate from their existing web proxy architecture without changing their network topology or client settings2. The firewall will maintain the same type of traffic flow as before, where HTTP and HTTPS requests contain the IP address of the web server and the client browser is redirected to the proxy1.
Answer A is not correct because DNS proxy is a type of web proxy that intercepts DNS queries from clients and resolves them using an external DNS server3. This type of proxy does not redirect HTTP or HTTPS requests to the firewall.

NEW QUESTION # 170
Which log type would provide information about traffic blocked by a Zone Protection profile?
- A. Traffic
- B. Threat
- C. Data Filtering
- D. IP-Tag
Answer: B
Explanation:
https://knowledgebase.paloaltonetworks.com/KCSArticleDetail?id=kA10g000000ClhzCAC
* D is the correct answer because the threat log type would provide information about traffic blocked by a Zone Protection profile. This is because Zone Protection profiles are used to protect the network from attacks, including common flood, reconnaissance attacks, and other packet-based attacks1. These attacks are classified as threats by the firewall and are logged in the threat log2. The threat log displays information such as the source and destination IP addresses, ports, zones, applications, threat types, actions, and severity of the threats2.

NEW QUESTION # 173
A company wants to install a NGFW firewall between two core switches on a VLAN trunk link. They need to assign each VLAN to its own zone and to assign untagged (native) traffic to its own zone.
Which option differentiates multiple VLANs into separate zones?
- A. Create V-Wire objects with two V-Wire subinterfaces and assign only a single VLAN ID to the "Tag Allowed" field of the V-Wire object. Repeat for every additional VLAN and use a VLAN ID of 0 for untagged traffic. Assign each interface/subinterface to a unique zone.
- B. Create VLAN objects for each VLAN and assign VLAN interfaces matching each VLAN ID. Repeat for every additional VLAN and use a VLAN ID of 0 for untagged traffic. Assign each interface/subinterface to a unique zone.
- C. Create Layer 3 subinterfaces that are each assigned to a single VLAN ID and a common virtual router. The physical Layer 3 interface would handle untagged traffic. Assign each interface/subinterface to a unique zone. Do not assign any interface an IP address.
- D. Create V-Wire objects with two V-Wire interfaces and define a range of "0-4096" in the "Tag Allowed" field of the V-Wire object.
Answer: C

NEW QUESTION # 176
When configuring explicit proxy on a firewall, which interface should be selected under the Listening interface option?
- A. ingress for the outgoing traffic to the internet
- B. Loopback for the proxy
- C. Firewall management
- D. ingress for the client traffic
Answer: B
Explanation:
When configuring an explicit proxy on a firewall, the Loopback interface is typically selected under the Listening interface option. The loopback interface is used because it allows the firewall to listen for proxy traffic independently of any specific physical interface. This is ideal for situations where the proxy should listen for connections from clients, regardless of which interface they come from.
While interfaces like Ingress (client-side) and Egress (internet-side) may handle the traffic flow, the loopback interface ensures that the proxy can handle requests from any source without being tied to a specific physical interface.
