2V0-41.24 Question 162
Single answerAn administrator is designing a VMware NSX environment and needs to determine whether to use routing or bridging for traffic between two segments. Segment A is configured with an IP subnet of 192.168.1.0/24, and Segment B is configured with an IP subnet of 192.168.2.0/24. The administrator also needs to ensure optimal performance and scalability for east-west traffic. Which network forwarding method should the administrator use in this scenario?
- A
Routing, as it is required to forward traffic between different IP subnets.
- B
Routing, as it minimizes east-west traffic within a single data center.
- C
Bridging, as it allows communication between segments with different IP subnets.
- D
Bridging, as it uses Layer 3 forwarding for scalability.
Show answer and explanation
Correct answer: A
Explanation
Routing is the correct choice when forwarding traffic between different IP subnets, as it operates at Layer 3 and ensures communication between distinct network segments. In this scenario, Segment A and Segment B are on separate IP subnets, making routing the appropriate method to achieve proper connectivity. Bridging, by contrast, is used to connect devices within the same Layer 2 domain and is not suitable for communication between different subnets.
- A. Correct.
Correct. Routing is required to forward traffic between different IP subnets, such as 192.168.1.0/24 and 192.168.2.0/24. NSX logical routers handle this efficiently.
- B. Incorrect.
Incorrect. Routing does not minimize east-west traffic by default; it depends on the network design and traffic patterns. However, routing is chosen here for IP subnet communication.
- C. Incorrect.
Incorrect. Bridging is used for communication within the same Layer 2 domain, not between different IP subnets.
- D. Incorrect.
Incorrect. Bridging operates at Layer 2 and does not use Layer 3 forwarding. It cannot handle communication between different IP subnets.
