Why each option
This question tests knowledge of the specific optics standard used by the 12-port 100 GE Cisco Nexus 7700 F3 Series I/O module.
The 12-port 100 GE F3 Series I/O module uses CPAK optics, which is Cisco's proprietary 100 Gigabit Ethernet optical transceiver format. CPAK modules are compact compared to CFP and were specifically adopted by Cisco for high-density 100GbE line cards in the Nexus 7700 platform.
QSFP+ is a 40 GbE transceiver standard and is not used for 100 GbE ports on the F3 I/O module.
SFP and SFP+ support 1 GbE and 10 GbE respectively and cannot provide the 100 GbE speeds this module requires.
CFP is a 100 GbE optics standard but is larger and is not used in the Nexus 7700 F3 12-port 100 GE module.
