An organization wants to use the Cisco SD-WAN regionalized service-chaining feature to optimize cost and user experience with applications in the network, which allows branch routers to analyze and steer traffic toward the required network function. Which feature meets this requirement?
The Cisco SD-WAN regionalized service-chaining feature that allows branch routers to analyze and steer traffic toward the required network function is best met by 'VNF Service Chaining'. This feature ensures that specific services can be efficiently orchestrated and directed as needed, optimizing both cost and user experience with applications in the network. Unlike Cloud onRamp solutions which are designed for integrating with cloud services and colocation environments, VNF Service Chaining directly addresses the requirement for advanced traffic steering and service chaining.
A: ? "With the Cisco SD-WAN Cloud onRamp for Colocation solution built specifically for colocation facilities, the solution routes the traffic to the best-permissible path from branches and remote workers to where all applications are hosted" https://www.cisco.com/c/en/us/td/docs/routers/sdwan-cloud-onramp-for-colocation/solution-user-guide/cisco-sdwan-cloud-onramp-colocation-solution-guide-19_1/about-cisco-sd-wan-Cloud-OnRamp-for-Colocation-solution.html
cloud on ramp for colocation is used when you have a colocation datacenter and you want to forward traffic there. for example you have a firewall there and from the firewall you want to redirect traffic to a second service in the same colocation building.( service chaining)
VNF Service Chaining. (Virtual Network Function Service Chaining). The question asks how to provide service chaining to a network function. They practically put the answer in the question.
A is correct. Page 96 and 112 you can see the difference between Service-chaining and VNF ser ice chaining https://www.cisco.com/c/dam/en/us/solutions/collateral/enterprise-networks/sd-wan/nb-06-cisco-sd-wan-ebook-cte-en.pdf
Is correct
Service chaining ?
I think that is correct
A is correct
Cloud on-ramps are solutions designed to help organizations quickly and securely obtain cloud connectivity solutions.
Key word " regionalized" - Would say answer is A
RafaJohnston is correct, document explains it well.
