NEW QUESTION # 77
An administrator needs to optimize traffic to prefer business-critical applications over non-critical applications QoS natively integrates with which feature to provide service quality?
- A. certificate revocation
- B. Content-ID
- C. App-ID
- D. port inspection
Answer: C
Explanation:
Explanation
QoS natively integrates with App-ID, which is a feature that identifies applications based on their unique characteristics and behaviors, regardless of port, protocol, encryption, or evasive tactics. By using App-ID, QoS can prioritize or limit traffic based on the application name, category, subcategory, technology, or risk level. Certificate revocation is a process of invalidating digital certificates that are no longer trusted or secure.
Content-ID is a feature that scans content and data within allowed applications for threats and sensitive data.
Port inspection is a method of identifying applications based on the TCP or UDP port numbers they use, which is not reliable or granular enough for QoS purposes. References:

NEW QUESTION # 79
A user at an external system with the IP address 65.124.57.5 queries the DNS server at 4. 2.2.2 for the IP address of the web server, www,xyz.com. The DNS server returns an address of 172.16.15.1 In order to reach Ire web server, which Security rule and NAT rule must be configured on the firewall?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Explanation
The addresses used in destination NAT rules always refer to the original IP address in the packet (that is, the pre-translated address). The destination zone in the NAT rule is determined after the route lookup of the destination IP address in the original packet (that is, the pre-NAT destination IP address). The addresses in the security policy also refer to the IP address in the original packet (that is, the pre-NAT address). However, the destination zone is the zone where the end host is physically connected. In other words, the destination zone in the security rule is determined after the route lookup of the post-NAT destination IP address.

NEW QUESTION # 80
An engineer is tasked with configuring SSL forward proxy for traffic going to external sites. Which of the following statements is consistent with SSL decryption best practices?
- A. The forward trust certificate should not be stored on an HSM.
- B. Check both the Forward Trust and Forward Untrust boxes when adding a certificate for use with SSL decryption
- C. The forward untrust certificate should be signed by a certificate authority that is trusted by the clients.
- D. The forward untrust certificate should not be signed by a Trusted Root CA
Answer: C
Explanation:
According to the PCNSE Study Guide, SSL forward proxy is a feature that allows the firewall to decrypt and inspect SSL traffic going to external sites. The firewall acts as a proxy between the client and the server, generating a certificate on the fly for each site. The best practices for configuring SSL forward proxy are:
Use a forward trust certificate that is signed by a certificate authority (CA) that is trusted by the clients. This certificate is used to sign certificates for sites that have valid certificates from trusted CAs. The clients will not see any certificate errors if they trust the forward trust certificate.
Use a forward untrust certificate that is not signed by a trusted CA. This certificate is used to sign certificates for sites that have invalid or untrusted certificates. The clients will see certificate errors if they do not trust the forward untrust certificate. This helps alert users of potential risks and prevent man-in-the-middle attacks.
Do not store the forward trust or untrust certificates on an HSM (hardware security module). The HSM does not support on-the-fly signing of certificates, which is required for SSL forward proxy.

NEW QUESTION # 83
How should an administrator enable the Advance Routing Engine on a Palo Alto Networks firewall?
- A. Enable Advanced Routing in Network > Virtual Routers > Router Settings > General, then commit and reboot.
- B. Enable Advanced Routing in Network > Virtual Routers > Redistribution Profiles and then commit.
- C. Enable Advanced Routing in General Settings of Device > Setup > Management, then commit and reboot.
- D. Enable Advanced Routing Engine in Device > Setup > Session > Session Settings, then commit and reboot.
Answer: A
Explanation:
The Advanced Routing Engine in Palo Alto Networks firewalls enhances the capabilities of routing functionalities, allowing for more complex and robust routing configurations. To enable the Advanced Routing Engine on a Palo Alto Networks firewall, an administrator needs to navigate to the Network tab, select Virtual Routers, and then access the settings for the specific virtual router they wish to configure. Within the Router Settings under the General tab, there's an option to enable Advanced Routing features. After enabling this option, the administrator must commit the changes and perform a system reboot for the changes to take effect. This process allows the firewall to utilize advanced routing protocols and features, enhancing its ability to manage and route traffic more efficiently across different network segments.
