In dense server environments, which component is commonly used to enable compute acceleration via PCIe or mezz hardware?

• A. Mezzanine card.
• B. KVM module.
• C. Cable labeling.
• D. POST.

Answer: (A)

The capability being tested is how to add compute acceleration in dense servers without sacrificing space. Mezzanine cards provide a compact, high-bandwidth PCIe expansion by plugging into dedicated mezzanine slots on a server blade or motherboard. This arrangement lets accelerators like GPUs, FPGAs, or fast NICs sit right next to the CPU with direct PCIe lanes, delivering strong performance while preserving chassis density and simplifying cabling. Some servers even support hot-swapping these cards, which helps keep dense configurations flexible and maintainable. In contrast, a KVM module is for keyboard/video/mouse control, not acceleration; cable labeling is just organization; POST is a boot-time self-test, not an acceleration path.
