NEW QUESTION # 87
An engineer is configuring a Protection profile to defend specific endpoints and resources against malicious activity.
The profile is configured to provide granular defense against targeted flood attacks for specific critical systems that are accessed by users from the internet.
Which profile is the engineer configuring?
- A. Vulnerability Protection
- B. Packet Buffer Protection
- C. DoS Protection
- D. Zone Protection
Answer: C
Explanation:
Explanation
The engineer is configuring a DoS Protection profile to defend specific endpoints and resources against malicious activity. A DoS Protection profile is a feature that enables the firewall to detect and prevent denial-of-service (DoS) attacks that attempt to overwhelm network resources or disrupt services. A DoS Protection profile can provide granular defense against targeted flood attacks for specific critical systems that are accessed by users from the internet, such as web servers, DNS servers, or VPN gateways. A DoS Protection profile can be applied to a security policy rule that matches the traffic to and from the protected systems, and can specify the thresholds and actions for different types of flood attacks, such as SYN, UDP, ICMP, or other IP floods12.

NEW QUESTION # 90
A company CISO updates the business Security policy to identify vulnerable assets and services and deploy protection for quantum-related attacks. As a part of this update, the firewall team is reviewing the cryptography used by any devices they manage. The firewall architect is reviewing the Palo Alto Networks NGFWs for their VPN tunnel configurations. It is noted in the review that the NGFWs are running PAN-OS
11.2. Which two NGFW settings could the firewall architect recommend to deploy protections per the new policy? (Choose two)
- A. IPsec with Hybrid ID exchange
- B. IKEv1 only to deactivate the use of public key encryption
- C. IKEv2 with Post-Quantum Pre-shared Keys
- D. IKEv2 with Hybrid Key exchange
Answer: C,D
Explanation:
Quantum-related attack protection requires cryptography resistant to quantum computing, such as post- quantum algorithms. In PAN-OS 11.2, IKEv2 with Hybrid Key Exchange (Option B) combines classical and quantum-resistant algorithms for key exchange, enhancing VPN security. IKEv2 with Post-Quantum Pre- shared Keys (PPK) (Option C) uses pre-shared keys designed to resist quantum attacks, supported in IKEv2 configurations.
Option A (IKEv1 only) weakens security by avoiding PFS and modern cryptography. Option D (IPsec with Hybrid ID exchange) is not a valid PAN-OS feature. Documentation confirms IKEv2 enhancements for quantum resistance.
Reference: PAN-OS 11.2 Administrator's Guide, "VPNs" section - IKEv2 and Quantum-Resistant Cryptography.
NEW QUESTION # 91
Which three authentication services can administrator use to authenticate admins into the Palo Alto Networks NGFW without defining a corresponding admin account on the local firewall? (Choose three.)
- A. Kerberos
- B. SAML
- C. PAP
- D. TACACS+
- E. LDAP
- F. RADIUS
Answer: A,B,E
Explanation:
https://docs.paloaltonetworks.com/pan-os/8-0/pan-os-admin/firewall-administration/manage-firewall-administrators/administrative-authentication
The administrative accounts are defined on an external SAML, TACACS+, or RADIUS server. The server performs both authentication and authorization. For authorization, you define Vendor-Specific Attributes (VSAs) on the TACACS+ or RADIUS server, or SAML attributes on the SAML server. PAN-OS maps the attributes to administrator roles, access domains, user groups, and virtual systems that you define on the firewall. For details, see:
Configure SAML Authentication Configure TACACS+ Authentication Configure RADIUS Authentication

NEW QUESTION # 95
A network administrator is troubleshooting an issue with Phase 2 of an IPSec VPN tunnel. The administrator determines that the lifetime needs to be changed to match the peer.
Where should this change be made?
- A. IKE Gateway profile
- B. IKE Crypto profile
- C. IPSec Crypto profile
- D. IPSec Tunnel settings
Answer: C
Explanation:
The **IKE crypto profile** is used to set up the encryption and authentication algorithms used for the key exchange process in IKE Phase 1, and lifetime of the keys, which specifies how long the keys are valid. To invoke the profile, you must attach it to the IKE Gateway configuration. The **IPSec crypto profile** is invoked in IKE Phase 2. It specifies how the data is secured within the tunnel when Auto Key IKE is used to automatically generate keys for the IKE SAs.
NEW QUESTION # 96
Which DoS protection mechanism detects and prevents session exhaustion attacks?
- A. Resource Protection
- B. Packet Based Attack Protection
- C. Flood Protection
- D. TCP Port Scan Protection
Answer: A
Explanation:
Reference:
In addition to setting IP flood thresholds, you can also use DoS Protection profiles to detect and prevent session exhaustion attacks in which a large number of hosts (bots) establish as many sessions as possible to consume a target's resources. On the profile's Resources Protection tab, you can set the maximum number of concurrent sessions that the device(s) defined in the DoS Protection policy rule to which you apply the profile can receive. When the number of concurrent sessions reaches its maximum limit, new sessions are dropped.

NEW QUESTION # 98
An administrator is using Panorama and multiple Palo Alto Networks NGFWs. After upgrading all devices to the latest PAN-OS?software, the administrator enables log forwarding from the firewalls to Panorama. Pre-existing logs from the firewalls are not appearing in Panorama.
Which action would enable the firewalls to send their pre-existing logs to Panorama?
- A. Use the import option to pull logs into Panorama.
- B. The log database will need to exported form the firewalls and manually imported into Panorama.
- C. A CLI command will forward the pre-existing logs to Panorama.
- D. Use the ACC to consolidate pre-existing logs.
Answer: C
Explanation:
After you upgrade to a Panorama 8.0 or later release, Panorama Log Collectors use a new log storage format.
Because Panorama cannot generate reports or ACC data from logs in the pre-8.0-release log format after you upgrade, you must migrate the existing logs as soon as you upgrade Panorama and its Log Collectors from a PAN-OS 7.1 or earlier release to a PAN-OS 8.0 or later release and you must do this before you upgrade your managed firewalls. Panorama will continue to collect logs from managed devices during the log migration but will store the incoming logs in the new log format after you upgrade to a PAN-OS 8.0 or later release. For this reason, you will see only partial data in the ACC and in Reports until Panorama completes the log migration process.

An administrator is configuring a Panorama device group
Which two objects are configurable? (Choose two )
- A. SSL/TLS roles
- B. DNS Proxy
- C. Address groups
- D. URL Filtering profiles
Answer: C,D
Explanation:
Explanation
URL filtering is a feature in Palo Alto Networks firewalls that allows administrators to block access to specific URLs[1]. This feature can be configured via four different objects: Custom URL categories in URL Filtering profiles, PAN-DB URL categories in URL Filtering profiles, External Dynamic Lists (EDL) in URL Filtering profiles, and Custom URL categories in Security policy rules. The evaluation order for URL filtering is:
Custom URL categories in URL Filtering profile, PAN-DB URL categories in URL Filtering profile, EDL in URL Filtering profile, and Custom URL category in Security policy rule.
