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.

Can't really get simpler than p2p. https://www.ciscopress.com/articles/article.asp?p=2832405&seqNum=5

The topology that best combines simplicity, quality, and availability is A. Partial mesh. It offers a practical compromise, providing redundant paths for availability and quality while being less complex than a full mesh.

Partial Mesh provides a balance of simplicity, quality, and availability by connecting only some critical nodes while reducing redundancy and cost compared to a Full Mesh.

Only partial mesh topology provides balance between simplicity, quality and availability. P2P cannot consider if availability is a factor.

I agree on it. As we are talking about WAN topology and not technology, partial mesh is the best fit. Since, A. Also Chat GPT suggested it.

Partial Mesh offers the best combination of simplicity, quality, and availability, making it the optimal choice for many WAN designs.

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
