A degree-1 node is a node that only has one direction, and it is therefore a terminal node. This means that the node only has one input and one output port. It does not have any other ports to connect to other nodes or fibers. This is a common feature of some optical transport networks, such as ring networks, where a degree-1 node serves as the endpoint of the ring.

Sounds like it's used for In-Line-Amplifiers too.

I thought degree-1 nodes had two sides, not just one!

A degree-1 node has one direction, right?

I believe it has to do with directional properties, but I can't remember if it’s specifically east and west or just one direction overall.

I thought degree-1 meant it only had one express channel, but now I'm confused about the two sides part.

I remember practicing a question about nodes, and I feel like degree-1 might refer to something like an In-Line-Amplifier, but I can't recall the details.

I think a degree-1 node is related to having just one direction, but I'm not sure if it's specifically for terminal nodes.
NO

I'm not too confident on this one. The options seem a bit confusing, but I'll give it my best shot and hope for the best.

Okay, I think I've got this. A degree-1 node is a node with only one direction, so it must be a terminal node. I'll go with option A.

Hmm, I'm a bit unsure about this one. I'll need to review my notes on graph theory to make sure I understand the concept of a degree-1 node.

This looks like a straightforward question about graph theory. I'll think through the options carefully and try to eliminate the incorrect ones.

Okay, I've got this. The requirement is to track the shoe designs by product, and make sure they can't be deleted. So I think the best approach is option A - adding a custom master-detail field for the shoe designs on the Product object. That way they're linked to the product but still have their own records that can't be deleted.

I'm just gonna choose C and hope the grader has a sense of humor. A node with east and west sides, but no north or south? Sounds like my love life.

Wait, is this a trick question? What if the answer is none of the above and it's actually a degree-1 node that can only communicate with pigeons?

D) A node with one direction only and therefore used as In-Line-Amplifier (ILA)

Oh man, this is a tough one. I'm torn between A and D, but I'll go with A just to be safe. Fingers crossed!

I think it's A, a terminal node.

Hmm, that makes sense too. It could be D) after all.
RO

I disagree, I believe a degree-1 node is D) A node with one direction only and therefore used as In-Line-Amplifier (ILA).

B is the winner here. A node with only one express channel and two sides, that's what a degree-1 node is all about.
LO

I'm going with D. A node with one direction is used as an In-Line-Amplifier (ILA), that's gotta be the right answer.

Option A sounds right to me. A node with only one direction is a terminal node, makes sense.

I think it's A too. It's like a dead end in terms of directions.
