350-401 Question 77
Select 2An enterprise network engineer is tasked with implementing a virtualization solution that allows the creation of multiple logical devices on the same physical network device, ensuring secure traffic separation between them. Which of the following device virtualization technologies should the engineer consider?
- A
Virtual Routing and Forwarding (VRF)
- B
Cisco DNA Center
- C
Virtual Port Channel (vPC)
- D
Hypervisor-based virtual machines (VMs)
- E
Container-based virtualization
Show answer and explanation
Correct answers: A, E
Explanation
Device virtualization technologies like VRF and container-based virtualization allow the division of a physical network device into multiple logical devices or environments. VRF achieves this by maintaining separate routing tables, while containers provide isolated runtime environments. These technologies are widely used to ensure secure traffic separation and resource segmentation.
- A. Correct.
Virtual Routing and Forwarding (VRF) allows the creation of multiple routing tables on the same physical router or switch, enabling secure traffic separation for different tenants or services. This is a device virtualization technology.
- B. Incorrect.
Cisco DNA Center is a network management and automation tool, not a device virtualization technology. It does not create logical devices on physical hardware.
- C. Incorrect.
Virtual Port Channel (vPC) is a technology used for link aggregation and redundancy, not device virtualization. It does not create multiple logical devices.
- D. Incorrect.
Hypervisor-based virtual machines (VMs) are a form of server virtualization rather than a device virtualization technology specific to network devices.
- E. Correct.
Container-based virtualization, such as Docker containers, can be used to create isolated environments on a device. This is relevant to device virtualization in certain network contexts.
