100-150 Question 174
Single answerYou are tasked with connecting a new network switch to an existing fiber backbone in your organization. The switch has both Ethernet ports, SFP slots, and a USB port for configuration. Which port(s) should you use to connect the switch to the fiber backbone and why?
- A
Ethernet port, because it supports high-speed data transfer.
- B
SFP slot, as it is designed for fiber optic connections.
- C
USB port, as it is used to transfer configuration files.
- D
PoE-enabled Ethernet port, as it can power other devices while transferring data.
Show answer and explanation
Correct answer: B
Explanation
To connect the switch to a fiber backbone, the correct choice is the SFP slot because it is specifically designed to support fiber optic transceivers. Neither Ethernet ports nor PoE-enabled Ethernet ports can directly connect to fiber optic cables, and USB ports are not used for network connectivity.
- A. Incorrect.
Ethernet ports are used for standard copper-based connections and not typically compatible with fiber optic cables.
- B. Correct.
SFP (Small Form-Factor Pluggable) slots are designed to support modular transceivers for fiber optic connections, which makes them the correct choice for connecting to a fiber backbone.
- C. Incorrect.
USB ports are typically used for administrative purposes, such as loading configuration files onto the device, and not for network connectivity.
- D. Incorrect.
PoE-enabled Ethernet ports are used to power connected devices like IP phones or cameras, but they are not typically used for fiber optic connections.
