Palo Alto Networks System Engineer – Strata — Question 17

What is the key benefit of Palo Alto Networks single-pass architecture (SPA) design?

Answer options

• A. It requires only one processor to complete all the functions within the box.
• B. It allows the addition of new functions to existing hardware without affecting performance.
• C. It allows the addition of new devices to existing hardware without affecting performance.
• D. It decodes each network flow multiple times, therefore reducing throughput.

Correct answer: B

Explanation

The correct answer, B, highlights that Palo Alto Networks' SPA allows for the enhancement of capabilities without compromising performance. Option A is incorrect because SPA does not limit its operations to a single processor for all functions. Options C and D also misrepresent the architecture's capabilities, as C discusses device addition, which is not the focus, and D incorrectly states that multiple decodings reduce throughput rather than enhance efficiency.
