A. B. C. D.C
When using SFP (Small Form-Factor Pluggable) modules, there are some similarities between copper and fiber interfaces, which are as follows:
C. They provide minimal interruption to services by being hot-swappable: Both copper and fiber SFP modules are hot-swappable, meaning that they can be inserted or removed from a device while it's still powered on without causing any significant interruption to the services. This feature is useful for network administrators who need to replace or upgrade modules without disrupting network connectivity.
B. They accommodate single-mode and multi-mode in a single module: Both copper and fiber SFP modules can accommodate both single-mode and multi-mode fiber cables in a single module. This feature provides flexibility to network administrators to choose the appropriate fiber cable for their specific application without needing to purchase a different module.
A. They support an inline optical attenuator to enhance signal strength: This statement is incorrect. An inline optical attenuator is a device used to decrease the signal strength of a fiber optic link, and it is not used to enhance the signal strength. Therefore, this option is not the same for both copper and fiber interfaces when using SFP modules.
D. They offer reliable bandwidth up to 100 Mbps in half duplex mode: This statement is incorrect as well. SFP modules do not limit the bandwidth of the interface; rather, the bandwidth is determined by the device's capabilities and the network topology. Therefore, this option is not the same for both copper and fiber interfaces when using SFP modules.
In summary, the correct answer is C, as both copper and fiber SFP modules provide minimal interruption to services by being hot-swappable.
