I would say 7 collision domains, 2 broadcast domains. One broadcast domain per subnet and there ar 2 subnets: one per router-interface and one collision domain per used switchport 6 used switchports on the switch connected to e1 of the router and one collision domain for the HUB connected to e0 of the router.
I agree with Juergen Ilse 7 collosion domains and 2 braodcast domains. Router has 2 broadcast domain e0 Sales and e1 Production. Router will not allow broadcasts from one of its connected network segment to cross the router and reach another network segment. The primary function of a Router is to segment divide a big broadcast domain in to multiple smaller broadcast domains.
Hub connected to E0 interface of the router Sales First Broadcast domain. Hub is considered as a single collosion domain.. First Collosion domain. Switch connected to E1 interface of the router Production Second Broadcast domain. Usually switches are used to segment divide a big Collision domain to many small collision domains.
Each port of an Ethernet Switch is operating in a separate Collision domain. I will say this is a bit more complicated than first meets the eyes. For example, two networks separated by a router are in two separate broadcast domains. Answer is B. The switch creates 12 collision domains and 1 broadcast domain.
A switch creates a single broadcast domain, not separate broadcast domains so any answer with 12 broadcast domains is incorrect. A switch creates separate collision domains for each port, not a single collision domain for the entire switch.

Network Segments and Domains With a basic understanding of how switches and routers work, you can add three additional network terms: segment, broadcast domain, and collision domain. Network segment.
A portion of a network that is separate from other portions of a network. In many instances, it is a single cable, such as a between a computer and a switch. On a shared, electrical bus such as 10BASE5 or 10BASE2, collisions can be detected by comparing transmitted data with received data or by recognizing a higher than normal signal amplitude on the bus.
On all other media, a carrier sensed on the receive channel while transmitting triggers a collision event. One of the simpler forms of collision detection is between two rectangles that are axis aligned — meaning no rotation. The algorithm works by ensuring there is no gap between any of the 4 sides of the rectangles. Any gap means a collision does not exist.
It is said that a Switch breaks up Collision domains because each port on it is its own collision domain, as apposed to a Hub, for example, where all of its ports belong to the same Collision domain.
Bridge: Expands Broadcast domains and breaks up Collision Domains. When you create VLANs, you are given the ability to create smaller broadcast domains within a layer-2 switched internetwork by assigning different ports on the switch to different subnetworks.
Which of the following devices is used to break up a broadcast domain? Answer — B — A router is used to break up broadcast domains. Key Takeaway: A broadcast domain is a logical division of a computer network in which all nodes can reach each other by broadcast at the data link layer. Explanation: A router defines a broadcast boundary, so every link between two routers is a broadcast domain. In the exhibit, 4 links between routers make 4 broadcast domains. A router can reduce the size of the broadcast domain because routers create a smaller network, thus creating a smaller broadcast domain.

How many collision domains exist on a 24 port hub? Answer Description Because there are 24 ports, there are 24 broadcast and 24 collision domains.
