Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which of the following technologies or devices cannot isolate broadcast domains?

A	Router
B	VLAN
C	Hub
D	Firewall

Explanation:

Detailed explanation-1: -The Hub cannot isolate broadcast domains.

Detailed explanation-2: -VLANs and routers are used to break up broadcast domains.

Detailed explanation-3: -Routers don’t break broadcast domains. They forward unicasts between them. A router forwards packets by their destination address and how that matches its routing table. Switches forward (flood) broadcasts.

Detailed explanation-4: -Each VLAN is an individual broadcast domain because a broadcast in a given VLAN will never reach any ports in other VLANs. Normally, a port carries traffic only for the single VLAN to which it belongs. For a VLAN to span multiple switches on a single connection, a trunk is required to connect two switches.

Detailed explanation-5: -Routers and other higher-layer devices form boundaries between broadcast domains.
