Which statement best describes Network Interface (NI) modules in Alcatel switches?

• A. They are optional and rarely used.
• B. They number 10 or more and support 10/100 Ethernet and/or Gigabit Ethernet.
• C. They are limited to a single Gigabit port.
• D. They provide only console access.

Answer: (B)

Network Interface modules are the hardware that adds real Ethernet ports to a switch, expanding its ability to connect devices. They’re designed to provide multiple ports—usually ten or more—so a single module can serve many devices or uplinks, rather than just one port. The speeds they support cover both 10/100 Mbps and Gigabit Ethernet, so they can handle older and newer devices in the same environment. This combination of high port count and flexible speeds is what makes NI modules a core way to scale a switch’s connectivity.

That’s why this description fits best: NI modules aren’t just optional or rarely used; they are used to boost port density. They aren’t limited to a single Gigabit port, and they’re not only for console access, which is handled by separate management interfaces.
