https://www.cisco.com/c/en/us/products/interfaces-modules/40-gigabit-modules/index.html#:~:text=The%20Cisco%20QSFP%20BiDi%The type of transceiver module used for 40 Gigabit Ethernet connectivity is C. QSFP+ (Quad Small Form-factor Pluggable Plus).
QSFP+ transceiver modules are designed to support 40 Gigabit Ethernet and other high-speed connections, such as Infiniband and Fibre Channel. These modules are capable of transmitting data over a variety of media types, including single-mode and multi-mode fiber optics, as well as copper cables.
Compared to other transceiver modules, QSFP+ offers higher port density, allowing more connections in a smaller space. It also offers higher throughput and lower power consumption, making it an ideal choice for high-speed data center applications.
In contrast, SFP+ (Small Form-factor Pluggable Plus) is used for 10 Gigabit Ethernet connectivity, GBIC (Gigabit Interface Converter) is an older technology that is no longer commonly used, and XFP (10 Gigabit Small Form-factor Pluggable) is also used for 10 Gigabit Ethernet connectivity.
Therefore, in this case, the correct answer is C. QSFP+.
