2V0-41.24 Question 69
Select 3An administrator is troubleshooting an issue in an NSX-T deployment where ESXi hosts are not forwarding traffic to logical switches. Upon investigation, the administrator notices that the NSX kernel modules are not functioning correctly on the ESXi hosts. Which of the following statements describe the role of NSX kernel modules and NSX agents installed on ESXi in this scenario?
- A
NSX kernel modules enable distributed routing and switching functionality on ESXi hosts.
- B
NSX agents are responsible for communication between the ESXi host and the NSX Manager.
- C
NSX kernel modules are only required for physical NIC management and do not impact logical switch traffic.
- D
NSX agents handle the management of distributed firewall rules on ESXi hosts.
- E
NSX kernel modules are responsible for applying overlay encapsulation and decapsulation.
Show answer and explanation
Correct answers: A, B, E
Explanation
NSX kernel modules and agents are critical components on ESXi hosts in an NSX-T environment. The kernel modules provide distributed networking capabilities, such as switching, routing, and overlay encapsulation/decapsulation. The NSX agents facilitate communication between the ESXi hosts and NSX Manager, ensuring proper configuration and control. Understanding these components' roles is crucial for diagnosing and resolving network virtualization issues.
- A. Correct.
Correct. NSX kernel modules are essential for enabling distributed networking features, such as routing and switching, on the ESXi hosts.
- B. Correct.
Correct. NSX agents manage the communication between ESXi hosts and the NSX Manager, ensuring proper configuration and operation.
- C. Incorrect.
Incorrect. NSX kernel modules are not limited to physical NIC management; they are vital for logical network operations like distributed switching and encapsulation.
- D. Incorrect.
Incorrect. While NSX agents assist with certain management tasks, distributed firewall rules are primarily managed by other components within NSX.
- E. Correct.
Correct. NSX kernel modules perform critical functions like overlay encapsulation and decapsulation, which enable VXLAN/GENEVE-based networking.
