A potential customer requires an NGFW solution that enables high-throughput, low-latency network security and also inspects the application. Which aspect of the Palo Alto Networks NGFW capabilities…

Options

• Asingle-pass architecture (SPA)
• Bthreat prevention
• CGlobalProtect
• DElastic Load Balancing (ELB)

• B

• C

• D

Explanation

Single-Pass Architecture (SPA) is the correct answer because it is Palo Alto Networks' core design that processes network traffic exactly once through all security functions - firewall policy, application identification, threat inspection, and URL filtering - simultaneously rather than sequentially. This parallel processing is what enables high throughput and low latency without sacrificing deep application-layer inspection, directly satisfying both requirements in the question.

Why the distractors are wrong:

• B. Threat Prevention is a feature set (IPS, antivirus, anti-spyware) that runs on top of the NGFW - it doesn't describe the architectural mechanism that achieves performance efficiency.
• C. GlobalProtect is Palo Alto's VPN/remote access client solution - it extends security policies to remote users but has nothing to do with throughput or latency in the core firewall.
• D. Elastic Load Balancing (ELB) is an AWS service for distributing traffic across compute resources - it is not a Palo Alto Networks product or NGFW concept at all.

Memory tip: Think of SPA as a "one-stop checkpoint" - instead of sending your bag through multiple separate scanners (slowing you down), SPA runs all inspections simultaneously in a single pass, like one super-scanner. The keyword pairing to burn in: SPA = performance + application visibility together.
