On the HP Z620 Workstation, how many PCI slots is Gen 3x16(electrically and mechanically)?
The correct answer is A. 2. Option A (2) is correct because the HP Z620 Workstation has exactly two PCIe slots that are Gen 3 x16 in both the physical (mechanical) slot size and the electrical bandwidth - meaning both carry the full x16 lane count at Gen 3 speeds, not just a larger physical connector…

Explanation
Option A (2) is correct because the HP Z620 Workstation has exactly two PCIe slots that are Gen 3 x16 in both the physical (mechanical) slot size and the electrical bandwidth - meaning both carry the full x16 lane count at Gen 3 speeds, not just a larger physical connector wired with fewer lanes.
Options B (3), C (4), and D (5) are incorrect because the Z620's other expansion slots either operate at a lower PCIe generation, use fewer electrical lanes (e.g., x8 or x4 electrical in a larger mechanical housing), or are entirely different slot types (PCIe x1, PCI standard). Counting those would inflate the number.
Memory tip: Think "Z620 = dual x16 Gen 3" - the "6" in Z620 hints at the six-core Xeon support, and just as dual-socket workstations come in pairs, so do its top-tier PCIe slots. If you remember it's a two-socket platform built for paired, high-bandwidth cards, the answer "2" becomes intuitive.
