Definitely B) RJ45. It's the standard for networking.

NFC is cool, but not for connecting to switches!

Wait, are people really using DVI for this? That seems off.

RJ45 all the way! Can't believe anyone would pick anything else.

I thought USB-A was more common for devices?

Definitely RJ45, it's the standard for Ethernet.

I feel like NFC is more for mobile devices, so it can't be the right choice here. RJ45 seems like the best bet.

I’m a bit confused. I thought USB-A could connect devices, but maybe that's not for switches?

I practiced a similar question last week, and I believe RJ45 was the answer then too.

I think it's RJ45, but I’m not entirely sure. I remember it being used for Ethernet connections.
