200-301 Question 141
Single answerA network administrator is tasked with isolating routing tables for different departments within the same organization on a single router. Additionally, the administrator wants to ensure minimal resource overhead while maintaining logical separation. Which virtualization technology should be implemented in this scenario?
- A
Server virtualization
- B
Containers
- C
Virtual Routing and Forwarding (VRF)
- D
Hypervisors
Show answer and explanation
Correct answer: C
Explanation
Virtual Routing and Forwarding (VRF) is the most appropriate virtualization technology for isolating routing tables on a router. VRFs enable the logical separation of network traffic and routing instances on the same physical device without needing additional hardware. This is ideal for organizations that need to segment routing domains for different departments or customers.
- A. Incorrect.
Server virtualization is used to create virtual machines on a physical server, which is not suitable for isolating routing tables. This is more focused on running multiple operating systems on one hardware device.
- B. Incorrect.
Containers are lightweight environments that share the host OS kernel and are designed for application-level isolation, not for routing table separation.
- C. Correct.
Virtual Routing and Forwarding (VRF) allows for logical separation of routing tables on the same physical router, making it the correct choice for isolating routing tables for different departments.
- D. Incorrect.
Hypervisors manage virtual machines by allocating computing resources to each VM. While they are used in server virtualization, they are not relevant for isolating routing tables.
