Show Suggested Answer

Suggested Answer: A

A star topology is a network design where all devices are connected to a central hub, which acts as a central point of control and management for the network. This type of topology is commonly used in access networks, where a central node is used to aggregate traffic from multiple users or devices, and then forward it to the core network. This design allows for efficient use of resources and easy management of the network.

You know, an open eye could also mean the signal is being monitored by a very awake and alert engineer. Just sayin'.

C'mon, guys, an open eye is a textbook indicator of low noise. It's like saying the sky is blue or that my jokes are hilarious.

High jitter? Nah, that's not it. An open eye is a clear sign of high inter-symbolic interference. I'm certain of it!

I'm pretty sure an open eye means high distortion. Who needs a clear signal anyway, right?
