MCQeasy

An architect is configuring an application override policy to handle a proprietary internal application whose traffic is misidentified by App-ID. What is a critical architectural caveat of using Application Override?

A.Application Override bypasses App-ID deep packet inspection and all CDSS security profile inspections for the matched traffic.
B.Application Override automatically converts all UDP packets into reliable TCP streams.
C.Application Override requires a valid WildFire subscription to function on the dataplane.
D.Application Override automatically forces SSL decryption on all matched traffic regardless of decryption policy.

An enterprise architect is designing a Zero Trust Network Access (ZTNA) architecture using GlobalProtect and Prisma Access / NGFW integration. The design requires continuous trust verification where user device posture (e.g., disk encryption status, OS patch level) is reassessed periodically. How does the architecture enforce this?

A.Cortex Data Lake runs a port scan against every remote client IP address over the VPN tunnel.
B.The Active Directory domain controller forces a password change every 15 minutes for all remote workers.
C.Host Information Profile (HIP) checks collect endpoint security posture data periodically and feed HIP matches into Security Policy rules.
D.The firewall terminates the IPsec tunnel every 60 seconds, forcing a complete Layer-2 re-authentication handshake.
AnswerC

HIP profiles assess endpoint posture and allow security policies to dynamically enforce trust based on compliance.

Why this answer

GlobalProtect works with Cortex XDR and Host Information Profile (HIP) checks to evaluate device posture periodically and update dynamic security policy enforcement via HIP matches.

An architect is designing a high-performance network where multiple virtual routers and virtual systems (vsys) are configured on a PA-7000 series firewall. The security design requires inter-vsys traffic to undergo full CDSS threat inspection (WildFire, Vulnerability Protection, URL Filtering). How should this traffic flow be architected?

A.Configure a Dynamic NAT pool mapping vsys 1 private IP addresses directly to vsys 2 management IP addresses.
B.Route inter-vsys traffic through shared security zones using virtual routers or virtual wires with security profiles explicitly applied to the inter-vsys rules.
C.Configure a direct cross-connect cable between physical interface ports on the front panel to bridge the virtual systems at Layer 1.
D.Disable stateful inspection globally so that packets pass freely between virtual systems without session table creation.
AnswerB

Routing traffic through security zones with attached security profiles ensures full inspection between virtual systems.

Why this answer

Inter-vsys communication requires forwarding traffic between virtual systems using virtual wires (vswires) or via shared internal zones where security rules and CDSS profiles are explicitly applied between the vsys boundaries.

A security architect is configuring an Anti-Spyware profile on a Palo Alto Networks NGFW. The team wants to ensure that hosts infected with malware attempt-to-communicate with known Command-and-Control (C2) servers are automatically isolated. Which feature in the Anti-Spyware profile should be configured to achieve this redirection?

A.WildFire file forwarding
B.DNS Sinkhole
C.Packet Capture (Pcap)
D.URL filtering category override
AnswerB

DNS Sinkhole intercepts malicious DNS lookups and redirects the traffic to a designated sinkhole IP address for host identification.

Why this answer

DNS Sinkholing allows the firewall to intercept DNS requests to malicious domains and redirect the infected client to a sinkhole IP address, identifying compromised internal hosts.

An organization's security architecture requires that any file downloaded over web browsing or email must be blocked if its WildFire verdict is malicious, but files with unknown verdicts should be allowed to download while analysis occurs in the cloud. Which WildFire architectural profile setting achieves this?

A.Disable WildFire forwarding and configure a static EDL blocking all file extensions (.exe, .pdf, .zip).
B.Set the WildFire analysis profile action to 'Reset-Both' for all unknown file types, effectively blocking all file downloads.
C.Configure a Decryption Profile to drop all sessions containing binary file headers.
D.Configure the WildFire Analysis profile forwarding rule with 'forward' for unknown files and a Security Rule action of 'allow', while enabling Threat Prevention to block known malicious hashes.
AnswerD

Forwarding unknowns for analysis while allowing the stream (or using inline ML to block) fulfills the requirement to permit unknowns while blocking malicious.

Why this answer

WildFire inline analysis and forward profiles support 'download-after-verdict' or allowing unknown files while holding execution on endpoints, or allowing the download while the cloud analyzes the file in real time depending on the exact forwarding rule configuration. For inline blocking of unknowns, 'block session' can be selected; to allow unknown files while analyzing, the action is set to allow with forwarding.

An enterprise security architect is designing an intrusion prevention and threat intelligence architecture. Which TWO of the following statements accurately describe the behavior and capabilities of Palo Alto Networks Threat Prevention and CDSS integration? (Choose two)

Select 2 answers
A.Threat intelligence feeds can automatically integrate dynamic threat indicators via External Dynamic Lists (EDLs) without requiring firewall reboots or commits.
B.Threat Prevention inspects both inbound and outbound traffic flows for vulnerability exploit signatures across all supported protocols.
C.Vulnerability Protection signatures require manual administrator intervention every hour to compile raw C code on the firewall dataplane.
D.DNS Security profiles can only be applied to hardware firewalls and are unsupported in virtualized firewall form factors (VM-Series).
E.WildFire cloud updates are dependent on manual file hashing performed exclusively by local administrators via CLI.
AnswersA, B

EDLs update dynamically without triggering firewall configuration commits or reboots.

Why this answer

Threat Prevention inspects traffic bi-directionally for known exploits, and cloud threat intelligence automatically synchronizes threat signatures and IOCs globally to protect against zero-days and known attacks.

An architect is troubleshooting an issue where an NGFW with Advanced Threat Prevention is failing to inspect encrypted HTTPS traffic traversing the security gateway. The security team confirms that WildFire and Vulnerbility Protection profiles are attached to the security policy. What architectural omission is causing the lack of threat inspection?

A.Outdated WildFire signature database version on the local dataplane
B.Incorrect configuration of the Zone Protection profile on the egress interface
C.Missing Decryption policy and profile to decrypt SSL/TLS sessions
D.Failure to enable User-ID mapping for the source IP addresses
AnswerC

Content-based CDSS features require decrypted traffic to inspect the application payload inside SSL/TLS tunnels.

Why this answer

Without an SSL Decryption policy and associated decryption profile, the firewall cannot inspect the payload of encrypted HTTPS sessions, rendering CDSS capabilities like Vulnerability Protection and WildFire unable to inspect layer 7 contents.

An enterprise architect is configuring WildFire inline machine learning and analysis on a PA-7050 firewall. The security requirement states that potential zero-day malware must be blocked instantly at the session layer before the complete file download finishes. Which WildFire deployment setting satisfies this inline requirement?

A.Enabling DNS Security with automated command-and-control domain block lists
B.Deploying a local WF-500 appliance in private cloud mode with a 15-minute polling interval
C.Configuring Inline ML for WildFire within the Anti-Spyware and WildFire Analysis profiles
D.Enabling WildFire Analysis on the Security Rulebase with standard public cloud forwarding
AnswerC

Inline ML for WildFire uses machine learning models running directly on the hardware or leveraged via cloud services to block zero-day files in real-time.

Why this answer

Inline ML for WildFire enables the firewall to make real-time verdict determinations on PE files and other executable formats during the session before the file transfer completes.

An architect is designing user-based security policies for a campus network where users authenticate via captive portal. Some users connect via shared workstations. Which User-ID mapping method is best suited to accurately track individual user sessions in this environment?

A.Captive Portal authentication prompting users for credentials when accessing controlled network resources.
B.Configuring static IP-to-User bindings for every workstation in the building.
C.Relying entirely on Windows Security Log polling via the User-ID Agent.
D.Using DHCP server lease logs exclusively without secondary authentication.
AnswerA

Captive portal correctly attributes traffic to the authenticated user on shared workstations rather than mapping to the machine account.

Why this answer

Captive Portal prompts users for authentication credentials when they attempt to access network resources, making it ideal for shared workstations where IP-to-user mappings from Active Directory security logs would be inaccurate or ambiguous.
