What are two physical components of the Cisco UCS B-Series server? (Choose two.)

Mezzanine slots are physical expansion interfaces integrated into the UCS B-Series blade form factor, designed to accept optional adapters such as the Cisco Virtual Interface Card. These slots allow blades to gain additional networking or storage connectivity without requiring a separate PCIe expansion chassis.

UCS B-Series blades do not have their own power supplies; power is delivered centrally by the power supply units housed in the UCS 5100 Series chassis.

Blade servers do not have lockable front doors; they slide into chassis bays and are secured by a single blade release lever on the faceplate.

Fans and thermal management are the responsibility of the chassis fan modules, not individual blade hardware.

CPU sockets are fundamental physical components present on every UCS B-Series blade, accepting standard Intel Xeon processors. The blade's compute capability is determined by the CPUs installed in these sockets, making them a core blade-resident hardware element.
