2V0-41.24 Question 77
Single answerAn organization has deployed NSX-T Data Center and configured logical switches to segment their application workloads. A virtual machine (VM) on Segment A needs to communicate with another VM on Segment B. Both segments are connected to the same Tier-1 Gateway. Which component is responsible for ensuring the packet forwarding between these two segments?
- A
The Tier-1 Gateway's distributed router component
- B
The Edge Node's centralized service router (SR)
- C
The NSX Manager
- D
The physical network switch
Show answer and explanation
Correct answer: A
Explanation
In NSX-T Data Center, logical switching and routing are handled at the virtualized layer. When packets need to traverse between two segments connected to the same Tier-1 Gateway, the Tier-1 Gateway's distributed router (DR) component forwards the packets locally on the hypervisor, ensuring optimal east-west traffic performance without involving the physical network or centralized components like the SR.
- A. Correct.
The Tier-1 Gateway's distributed router component handles east-west traffic within the same Tier-1 Gateway efficiently by forwarding packets locally on the hypervisor.
- B. Incorrect.
The Edge Node's centralized service router (SR) is used for north-south traffic or when stateful services like NAT are required. It is not responsible for east-west traffic between segments on the same Tier-1 Gateway.
- C. Incorrect.
The NSX Manager is a management component and does not participate in data plane forwarding.
- D. Incorrect.
The physical network switch is not involved in logical switching within the NSX-T overlay network; it only facilitates the underlay network.
