Which of the following topologies is designed to fully support applications hosted in on-premises data centers, public or private clouds, and SaaS services?
Correct Answer: A
* SDWAN (Software-Defined Wide Area Network) is a topology that uses software to dynamically route traffic across multiple WAN links, such as broadband, LTE, or MPLS12. SDWAN can optimize the performance, security, and reliability of applications hosted in different locations, such as on-premises data centers, public or private clouds, and SaaS services3 .
* MAN (Metropolitan Area Network) is a topology that connects multiple LANs within a geographic area, such as a city or a campus . MAN is not designed to support applications hosted in different clouds or SaaS services, as it is limited by the physical distance and bandwidth of the WAN links.
* PAN (Personal Area Network) is a topology that connects devices within a short range, such as Bluetooth, infrared, or NFC . PAN is not designed to support applications hosted in different clouds or SaaS services, as it is limited by the wireless technology and the device capabilities.
* MPLS (Multiprotocol Label Switching) is a technology that uses labels to forward packets across a WAN, without relying on IP routing . MPLS can improve the performance and quality of service of applications hosted in different locations, but it is not a topology by itself, and it requires dedicated WAN links that are expensive and inflexible .
