A. B. C. D. E.



The Cisco platform that meets the requirement of delivering WAN gateways functionality to multi-tenant, provider-hosted clouds is the Cisco CSR 1000v.

The Cisco CSR 1000v is a virtual router that can be deployed in a virtualized environment, making it an ideal platform for cloud-based deployments. It supports a wide range of features and protocols that are necessary for WAN connectivity, including VPN, MPLS, and BGP. Additionally, it has a robust security feature set, including IPsec VPN and zone-based firewall.

The Cisco ASR 1000 series and the Cisco ASR 9000 series are also routers that support WAN connectivity, but they are physical routers and not virtualized like the Cisco CSR 1000v. While they may be appropriate for some use cases, they are not the best fit for multi-tenant cloud deployments due to their physical nature.

The Cisco NX-OS is an operating system that is primarily used for data center networking switches, and it does not support WAN connectivity or routing capabilities.

The Cisco CSR series is not a specific product, but rather a series of products that includes the Cisco CSR 1000v. Therefore, it is not a valid answer for this question.

In conclusion, the correct answer to this question is A. Cisco CSR 1000v.
