Which WAN topology provides a combination of simplicity quality, and availability?
A point-to-point WAN topology involves a dedicated connection between two endpoints. It is known for its simplicity because it requires minimal expertise to install and maintain. The quality of service is usually high as these connections are dedicated, reducing latency and jitter. Moreover, it offers constant availability, essential for applications such as VoIP and video over IP, due to its dedicated capacity.
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
LOL this is Cisco test anyway. so we must follow Cisco rule.
Thanks for the link, as @StingVN said it, even if nonsense, we must follow Cisco rules.
P2P? Shouldnt it be partial mesh? Since combines simplicity and availability, and is more available than hub and spoke.
so-called broken question. yes, it should be partial mesh.
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
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.
upvoting this one for pointing out WAN
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."
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.
The main reason "point-to-point" might not have been selected as the answer in this case could be due to the phrasing of the question and the possible comparison with the other options provided. "Point-to-point" is often considered simple and straightforward, but in terms of availability, it might lack redundancy compared to a "hub-and-spoke" topology where multiple remote sites connect to a central hub, which can provide better failover options.
C is correct
point to point
Point-to-point
Point to Point is simple but not to sure about reliable but C is the best answer
C is correct
I agree with splashy "Full mesh and even more so partial mesh from an enterprise perspective is anything but simple. Simplicity is the keyword as it is something a SOHO for example would prefer. A dedicated point-to-point connection is still more available than a normal broadband connection (consumer) which most people and companies use (broadband) with VPN." and with alan100 link that shows advantages of "Simplicity: Point-to-point communication links require minimal expertise to install and maintain.", "Quality: Point-to-point communication links usually offer high service quality" and "Availability: Point-to-point communication links provide permanent, dedicated capacity, which is required for VoIP or Video over IP. https://www.ciscopress.com/articles/article.asp?p=2832405&seqNum=5#:~:text=of%20Leased%20Lines-,Advantages,-Disadvantages
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 quality service, 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.
I bet on P2P
C is correct
IMO, answer A is correct, PARTIAL MESH. Please refer to CCNA Oficial Student Learning Guide page 217
In the context of the CCNA (Cisco Certified Network Associate) certification, redundancy and availability are related concepts, but they are not exactly the same thing. Redundancy refers to the use of duplicate components or backup systems to ensure continued operation in case of a failure. Redundancy is often implemented to minimize downtime and increase fault tolerance. For example, in a redundant network design, there might be multiple switches or routers providing backup paths in case the primary ones fail. Availability, on the other hand, is a measure of how accessible and reliable a network or system is to users. It indicates the percentage of time a network or system is operational and accessible to users. High availability means that the network or system is up and running most of the time, with minimal downtime.
