Both Copper and Fiber Interfaces: SFP Modules Comparison

C.

The correct answer is C: They provide minimal interruption to services by being hot-swappable.

Small Form-Factor Pluggable (SFP) modules are transceivers that can be plugged into switches, routers, and other network devices to connect them to a fiber optic or copper network. These modules are designed to be hot-swappable, meaning they can be inserted or removed from a device while it's still running, without causing any disruption to the network.

SFP modules come in two types: copper and fiber. Copper SFP modules are used to connect devices to copper Ethernet cables, while fiber SFP modules are used to connect devices to fiber optic cables.

While copper and fiber interfaces have their differences, one thing that they have in common is that they both support hot-swappable SFP modules. This means that if you need to replace a faulty SFP module or upgrade to a different type of module, you can do so without having to shut down the device or the network. This feature helps minimize network downtime and ensures that services remain uninterrupted.

To summarize, when using SFP modules, both copper and fiber interfaces provide minimal interruption to services by being hot-swappable.
