2V0-41.24 Question 67
Single answerAn administrator is troubleshooting network connectivity issues in an NSX-T Data Center environment. During the investigation, they check the ESXi host and observe that certain NSX kernel modules are not loaded. What is the primary role of these kernel modules and NSX agents installed on ESXi hosts in the NSX-T environment?
- A
To provide distributed network and security functionality at the hypervisor level.
- B
To manage the physical network uplinks connected to the virtual machines.
- C
To act as the control plane for all NSX-T components in the environment.
- D
To enable communication between the NSX Manager and the ESXi host for configuration and state synchronization.
Show answer and explanation
Correct answer: A
Explanation
NSX kernel modules installed on ESXi hosts are critical components that enable distributed network and security functionality, such as distributed routing and firewalling, at the hypervisor level. NSX agents complement these kernel modules by facilitating communication between the NSX Manager and the ESXi hosts for configuration and operational tasks. However, the primary purpose of kernel modules is to provide the foundational networking and security services that are essential to NSX-T functionality.
- A. Correct.
This is correct. NSX kernel modules are responsible for implementing distributed networking and security services, such as distributed firewall, distributed routing, and switching, directly at the hypervisor level.
- B. Incorrect.
This is incorrect. Managing physical uplinks is typically handled by the ESXi networking stack and not specifically by NSX kernel modules or agents.
- C. Incorrect.
This is incorrect. The NSX-T control plane is managed by NSX Manager and Central Control Plane (CCP) components, not by kernel modules or NSX agents on the ESXi host.
- D. Incorrect.
This is incorrect. While NSX agents do facilitate communication between NSX Manager and ESXi hosts, their primary role is not limited to configuration and state synchronization but extends to enabling distributed data plane services.
