Question: Show 
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. Also, each LAN that is connected to a router is a broadcast domain. The 4 LANs in the exhibit result in 4 more broadcast domains, so there are 8 broadcast domains in all. More Questions: Modules 1 – 4: Switching Concepts, VLANs,
and InterVLAN Routing Exam Answers , 2 Broadcast Domain and 5 Collision Domain : Broadcast Domain : As R1 has two ports so 2 broadcast domains because router has per-port broadcast domain. Collision Domain : As routers and switches has per-port collision domain. so there are total 5 collision . See Diagram : Collision Domain with Blue Color and Broadcast Domain with Red Color
D is the right answer. Router : has Per-port broadcast domain & per-port collision domain. So, There are 2 broadcast domains & 5 Collision domains.
I think the Answer is B Routers Provides A separate Broadcast Domain for each interface. Switch Creates separate collision domains with a single broadcast , therefore it's 2 broadcast and 3 collisions as i see the diagram

A. tracert address Answer: A Explanation To check the connectivity between a host and a destination (through some networks) we can use both “tracert” and “ping” commands. But the difference between these 2 commands is the “tracert” command can display a list of near-side router interfaces in the path between the source and the destination. Therefore the best answer in this case is A – tracert address. Note: “traceroute” command has the same function of the “tracert” command but it is used on Cisco routers only, not on a PC. Question 7 Refer to the exhibit. A network engineer is troubleshooting an internet connectivity problem on the computer. What causing the problem? A. wrong DNS server Answer: C Explanation The IP address of the PC (192.168.11.2/24) is not on the same network with its gateway 192.168.1.1 -> C is correct. Question 8 How many broadcast domains are shown in the graphic assuming only the default vlan is configured on the switches? A. one Answer: A Explanation Only router can break up broadcast domains but in this exhibit no router is used so there is only 1 broadcast domain. For your information, there are 7 collision domains in this exhibit (6 collision domains between hubs & switches + 1 collision between the two switches). Question 9 Refer to the exhibit. PC> tracert 10.16.176.23 1 31 ms 31 ms 32ms 172.16.182.1 Trace complete. Host A has tested connectivity to a remote network. What is the default gateway for host A? A.
172.16.182.1 Answer: A Explanation It will list all the routers (from nearest to farthest) it passes through until it reaches its destination so the first hop is its nearest IP. If we ping from a PC, it is also the default gateway for that PC -> A is correct. Question 10 What functions do routers perform in a network? (Choose two) A. packet switching Answer: A C Question 1 What are some of the advantages of using a router to segment the network? (Choose two) A. Filtering can occur based on Layer 3 information. Answer: A D Question 2 Which of the following statements describe the network shown in the graphic? (Choose two) A. There are two broadcast domains in the network. Answer: A F Explanation Only router can break up broadcast domains so in the exhibit there are 2 broadcast domains: from e0 interface to the left is a broadcast domain and from e1 interface to the right is another broadcast domain -> A is correct. Both router and switch can break up collision domains so there is only 1 collision domain on the left of the router (because hub doesn’t break up collision domain) and there are 6 collision domains on the right of the router (1 collision domain from e1 interface to the switch + 5 collision domains for 5 PCs in Production) -> F is correct. Question 3 Refer to the exhibit. The two connected ports on the switch are not turning orange or green. What would be the most effective steps to troubleshoot this physical layer problem? (Choose three) A. Ensure that the Ethernet encapsulations match on the interconnected router and switch ports. Answer: B D F Explanation The ports on the switch are not up indicating it is a layer 1 (physical) problem so we should check cable type, power and how they are plugged in. Question 4 For what two purposes does the Ethernet protocol use physical addresses? (Choose two) A. to uniquely identify devices at Layer 2 Answer: A E Explanation Physical addresses or MAC addresses are used to identify devices at layer 2 -> A is correct. MAC addresses are only used to communicate on the same network. To communicate on different network we have to use Layer 3 addresses (IP addresses) -> B is not correct; E is correct. Layer 2 frame and Layer 3 packet can be recognized via headers. Layer 3 packet also contains physical address -> C is not correct. On Ethernet, each frame has the same priority to transmit by default -> D is not correct. All devices need a physical address to identify itself. If not, they can not communicate -> F is not correct. Question 5 Refer to the exhibit. Two buildings on the San Jose campus of a small company must be connected to use Ethernet with a bandwidth of at least 100 Mbps. The company is concerned about possible problems from voltage potential difference between the two buildings. Which media type should be used for the connection? A. UTP cable Answer: D Explanation Because the company has problem about voltage potential difference between the two buildings so they should connect via fiber optic cable which uses light pulses to transmit information instead of using electronic pulses. How many broadcast domains are on a LAN?Eventually, the frame goes to every connected device in the LAN. Therefore all devices are in one broadcast domain. This logic applies to LANs with many switches.
How many broadcast domains are in a router with 8 interfaces?But in the switch case switch treats every port as its own collision domain.so if you have 8 port switch that means you will have 8 collision domains.
How do you broadcast a domain?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. A broadcast domain can be within the same LAN segment or it can be bridged to other LAN segments.
