350-401 Question 78
Select 3An organization is planning to implement device virtualization technologies to improve resource utilization and enable multiple virtual devices on a single hardware platform. Which of the following technologies would best meet their requirements?
- A
Virtual Routing and Forwarding (VRF)
- B
Hypervisor-based Virtual Machines
- C
Container-based Virtualization
- D
EtherChannel
- E
Network Address Translation (NAT)
- F
Cisco SD-WAN
Show answer and explanation
Correct answers: A, B, C
Explanation
Device virtualization technologies enable the creation of multiple logical instances or devices on a single hardware platform. VRF, Hypervisor-based Virtual Machines, and Container-based Virtualization directly address this requirement by isolating resources and enabling multiple independent operations. EtherChannel, NAT, and Cisco SD-WAN, while valuable in other contexts, do not meet the specific criteria for device virtualization in this scenario.
- A. Correct.
Virtual Routing and Forwarding (VRF) allows multiple routing tables to exist on the same router, providing isolation of network paths. This is a key device virtualization technology used in networking.
- B. Correct.
Hypervisor-based Virtual Machines enable the running of multiple operating systems on a single physical machine by virtualizing the hardware resources. This is a foundational device virtualization technology.
- C. Correct.
Container-based Virtualization uses lightweight containers to run multiple isolated instances of applications or services on a shared operating system, providing efficient device virtualization.
- D. Incorrect.
EtherChannel is a link aggregation technology that combines multiple physical links into a single logical link. While useful for increasing bandwidth and redundancy, it is not related to device virtualization.
- E. Incorrect.
Network Address Translation (NAT) translates IP addresses between private and public networks. It is a networking function and not a device virtualization technology.
- F. Incorrect.
Cisco SD-WAN is a software-defined networking solution for wide-area networks. While it provides network virtualization, it is not a direct device virtualization technology.
