2V0-41.24 Question 142
Single answerA virtual machine (VM) in Segment A needs to communicate with another VM in Segment B within the same single-tier NSX-T logical routing environment. Which of the following steps best describes the datapath of the packet when logical routing occurs?
- A
The packet is sent to the Tier-0 Gateway for routing before being forwarded to Segment B.
- B
The packet is routed locally within the hypervisor by the Tier-1 Gateway and forwarded to Segment B.
- C
The packet is encapsulated in a GENEVE tunnel and sent to the physical network for routing.
- D
The packet is sent to the Edge Node for routing and forwarded to Segment B.
Show answer and explanation
Correct answer: B
Explanation
In a single-tier NSX-T logical routing environment, the Tier-1 Gateway is responsible for routing packets between segments. Since both VMs reside in segments connected to the same Tier-1 Gateway, routing occurs locally within the hypervisor. This eliminates the need for packets to traverse the physical network or involve Edge Nodes, ensuring efficient communication.
- A. Incorrect.
Incorrect. In a single-tier routing setup, routing happens at the Tier-1 Gateway level, not Tier-0.
- B. Correct.
Correct. In a single-tier routing environment, the Tier-1 Gateway performs routing locally within the hypervisor, ensuring efficient packet delivery between segments.
- C. Incorrect.
Incorrect. While GENEVE encapsulation is used in NSX-T, it is not required for routing between segments within the same Tier-1 Gateway in a single-tier setup.
- D. Incorrect.
Incorrect. The Edge Node is not involved in single-tier routing unless services like NAT or load balancing are configured, which is not mentioned in this scenario.
