Exam 220-1101 topic 1 question 37 discussion

Get used to this. A Router separates Broadcast Domain while a Switch separate Collision Domain. Answer (C) takes the money here

The answer is Router. Routers and other higher-layer devices form boundaries between broadcast domains.

Router separates Broadcast domains.

C. Router

Router separates broadcast domain

Unlike the switch that increases broadcast domains and divides collison domains, The router divides out the broadcast domain. Which is the OSI Layer 2 funtion of the router.

Router or Layer-3 switch.

Router is used to separate broadcast domains. A router operates at the Network layer (OSI Layer 3) and acts as a boundary between different networks. It uses routing tables to determine the best path for data to travel from one network to another. Routers also use network address translation (NAT) to translate private IP addresses to public IP addresses, allowing multiple devices on a private network to access the internet using a single public IP address. Additionally, routers are used to separate broadcast domains, which means that broadcasts sent by one device on the network are not forwarded to other devices on the same network, effectively limiting the size of the broadcast domain and reducing network congestion.
