2V0-41.24 Question 79
Select 2A network administrator is troubleshooting a packet forwarding issue in a VMware NSX-T Data Center environment. They suspect that the packet is not being routed correctly and want to verify the role of different tables used in the forwarding process. Which tables are directly involved in determining the next-hop information for the packet?
- A
Forwarding Table
- B
MAC Table
- C
Routing Table
- D
ARP Table
- E
Firewall Table
Show answer and explanation
Correct answers: A, C
Explanation
In VMware NSX-T Data Center, the Forwarding Table and Routing Table are directly involved in determining the next-hop information for packet forwarding. The Forwarding Table maps destinations to specific ports or tunnels, while the Routing Table identifies the next-hop based on destination IP addresses. Other tables, such as the MAC Table and ARP Table, support the forwarding process but are not directly responsible for next-hop determination.
- A. Correct.
The Forwarding Table is used to determine the next-hop information and is critical in the packet forwarding process. It contains details mapping destinations to specific ports or tunnels.
- B. Incorrect.
The MAC Table is used for Layer 2 switching and maps MAC addresses to ports, but it is not directly involved in determining next-hop information for routing.
- C. Correct.
The Routing Table plays a key role in determining the next-hop for IP packets based on their destination IP addresses.
- D. Incorrect.
The ARP Table resolves IP addresses to MAC addresses but does not determine next-hop information directly. It supports the forwarding process indirectly by enabling Layer 2 communication.
- E. Incorrect.
The Firewall Table is used for enforcing security rules and does not participate in determining next-hop information for packet routing.
