Exam 200-301 topic 1 question 174 discussion

C is actually correct. Its P2P. According to Cisco Press, P2P (i.e Leased lines) have those exact advantages: https://www.ciscopress.com/articles/article.asp?p=2832405&seqNum=5

P2P? Shouldnt it be partial mesh? Since combines simplicity and availability, and is more available than hub and spoke.

1- x 2- L2 3- x 4- L3 and L2 5- L3 6- L3 But I style confused about the answer.

Hub-and-Spoke Topology: This topology consists of a central hub that connects to multiple spokes (remote sites). It provides a good balance of simplicity and availability, as it is easier to manage and requires fewer connections compared to a full mesh topology. Additionally, the hub acts as a central point for data traffic, which can enhance quality and reliability.

A is correct once availability becomes a factor , you cant choose P2P

P2P can refer to a straight connection between 2 nodes, but can also mean connection type. The article in the link is using the second meaning, comparing leased line to Dial-up and ISDN, but Dial-up and ISDN are not TOPOLOGY! And the question is asking topology.

C is correct

C is correct

The question is about WAN topology, not network topology! WAN point-to-point connections are such that remote devices seem to be on the same physical segment. It it is a clear C.

C is actually correct. Don't confuse availability with reliability. P2P is highly available because it's dedicated to only one connection, but it's not reliable, that means if the link fails the connexion goes down (because there is no redundant link acting as a backup). If the question mentioned reliability instead of availability, the answer would be A. thanks for @Alan100 for providing this link https://www.ciscopress.com/articles/article.asp?p=2832405&seqNum=5

point to point

Point-to-point

Cisco say that C is correct: "Simplicity: Point-to-point communication links require minimal expertise to install and maintain. Quality: Point-to-point communication links usually offer high service quality, if they have adequate bandwidth. The dedicated capacity removes latency or jitter between the endpoints. Availability: Constant availability is essential for some applications, such as e-commerce. Point-to-point communication links provide permanent, dedicated capacity, which is required for VoIP or Video over IP."

Point to Point is simple but not to sure about reliable but C is the best answer

IMO, answer A is correct, PARTIAL MESH. Please refer to CCNA Oficial Student Learning Guide page 217

Here's why "partial mesh" might not be the preferred option: Complexity: Partial mesh networks can become complex as the number of connections increases. Managing and maintaining the network can become challenging. Availability: While partial mesh can provide a degree of redundancy, it might not offer the same level of availability as some other topologies. If a link between critical sites fails, there might not be alternative routes. Quality: The quality of the connections might vary based on the specific links established in the partial mesh. Some connections might have higher latency or lower bandwidth than others.

C is correct
