2V0-41.24 Question 81
Single answerA network administrator is troubleshooting packet forwarding in an NSX-T Data Center environment. They observe that packets are being dropped and suspect an issue with one of the forwarding tables. Which table is responsible for determining the correct next-hop based on the destination IP address in the packet?
- A
MAC Table (MAC Forwarding Table)
- B
ARP Table
- C
Routing Table
- D
Connection Tracking Table
Show answer and explanation
Correct answer: C
Explanation
In NSX-T Data Center, the Routing Table plays a crucial role in the forwarding process at Layer 3. It determines the next-hop for packets based on their destination IP address. Understanding the purpose of each table used in packet forwarding is essential for diagnosing and resolving networking issues effectively.
- A. Incorrect.
The MAC Table is used to map MAC addresses to ports in order to forward Layer 2 traffic. It does not determine the next-hop for IP-based forwarding.
- B. Incorrect.
The ARP Table maps IP addresses to MAC addresses for Layer 2 communication. It is not responsible for determining the next-hop.
- C. Correct.
The Routing Table is responsible for determining the next-hop based on the destination IP address in the packet. It is used for Layer 3 forwarding decisions.
- D. Incorrect.
The Connection Tracking Table is used for stateful firewall operations and tracks active connections. It does not determine the next-hop for forwarding.
