2V0-41.24 Question 68
Select 3An organization has deployed VMware NSX to enhance its network virtualization capabilities. During a troubleshooting session, you are tasked with examining the function of kernel modules and NSX agents installed on ESXi hosts. Which of the following statements accurately describe their roles and functionality in the NSX architecture?
- A
Kernel modules on ESXi hosts handle packet forwarding and distributed firewall enforcement for NSX.
- B
NSX agents installed on ESXi hosts are responsible for managing the distributed logical router (DLR) control plane functions.
- C
Kernel modules on ESXi hosts are used to enable communication with VMware vCenter Server only.
- D
NSX agents on ESXi hosts communicate with the NSX Manager to receive configuration updates and push state changes.
- E
NSX agents installed on ESXi hosts are responsible for managing hardware offloading for physical NICs.
Show answer and explanation
Correct answers: A, B, D
Explanation
In the NSX architecture, kernel modules and NSX agents on ESXi hosts play distinct but complementary roles. Kernel modules operate at the data plane level, handling functions like packet forwarding and firewall enforcement. NSX agents, on the other hand, are part of the control plane and are responsible for tasks such as DLR management and communication with the NSX Manager to apply configuration updates. Understanding these roles is crucial when troubleshooting or designing NSX deployments.
- A. Correct.
Correct. Kernel modules on ESXi are responsible for critical data plane functions like packet forwarding and distributed firewall enforcement.
- B. Correct.
Correct. NSX agents are responsible for enabling control plane functions such as managing the DLR on the ESXi hosts.
- C. Incorrect.
Incorrect. Kernel modules on ESXi hosts are not solely used for communication with vCenter Server; they play a critical role in NSX's data plane operations.
- D. Correct.
Correct. NSX agents on ESXi hosts maintain communication with NSX Manager to receive configuration changes and synchronize state information.
- E. Incorrect.
Incorrect. NSX agents do not manage hardware offloading for physical NICs; this is typically handled by other VMware technologies like vSphere Distributed Switch (VDS) or hardware acceleration features.
