350-401 Question 74
Single answerAn organization is planning to deploy network functions virtualization (NFV) to reduce hardware dependency and improve scalability. They intend to virtualize multiple network functions, including firewalls and routers, using Cisco's virtualization technologies. Which Cisco solution provides the capability to virtualize these network functions on x86 servers?
- A
Cisco DNA Center
- B
Cisco NFVIS (Network Function Virtualization Infrastructure Software)
- C
Cisco ACI (Application Centric Infrastructure)
- D
Cisco SD-WAN
Show answer and explanation
Correct answer: B
Explanation
Cisco NFVIS is a key component of Cisco's virtualization portfolio, designed to enable the deployment of virtualized network functions on x86 servers. It supports hosting virtualized network appliances such as firewalls, routers, and other services, making it the correct choice for this scenario. Other options, such as Cisco DNA Center and Cisco ACI, focus on different areas of enterprise networking and do not provide the NFV capability required in this scenario.
- A. Incorrect.
Cisco DNA Center is a network management platform focused on automation, analytics, and policy creation for enterprise networks, but it does not provide network function virtualization.
- B. Correct.
Cisco NFVIS is specifically designed for virtualizing network functions on x86 servers, enabling the deployment of virtualized network services such as routers, firewalls, and WAN accelerators.
- C. Incorrect.
Cisco ACI is a data center solution that provides software-defined networking (SDN) capabilities and application-centric policy management, but it is not focused on virtualizing network functions.
- D. Incorrect.
Cisco SD-WAN is a solution for managing wide-area networks using software-defined principles, but it is not responsible for virtualizing network functions.
