2V0-21.23 Question 171
Select 3An administrator is tasked with adding multiple ESXi hosts to an existing vSphere Distributed Switch (vDS). The administrator wants to ensure minimal disruption to the network traffic during this process. Which of the following actions should the administrator take to achieve this goal?
- A
Migrate the VMkernel adapters to the distributed switch before adding the ESXi hosts.
- B
Use the Add and Manage Hosts wizard in the vSphere Client to add the ESXi hosts to the distributed switch.
- C
Ensure all physical network adapters (uplinks) on the ESXi hosts are assigned to the distributed switch.
- D
Manually configure each ESXi host's network settings before adding them to the distributed switch.
- E
Verify the distributed switch version is compatible with the ESXi host version before adding the hosts.
Show answer and explanation
Correct answers: B, C, E
Explanation
Adding ESXi hosts to a vSphere Distributed Switch requires careful planning to avoid network disruptions. The Add and Manage Hosts wizard automates and streamlines the process, while ensuring uplinks are correctly assigned guarantees physical network connectivity. Verifying version compatibility ensures the distributed switch and ESXi hosts can work together without errors. Incorrect options involve steps that are either redundant, inefficient, or not possible in the context of the task.
- A. Incorrect.
Incorrect: Migrating VMkernel adapters before adding the host is not possible because the host must first be added to the distributed switch to access its networking configuration.
- B. Correct.
Correct: The Add and Manage Hosts wizard is the recommended method to add ESXi hosts to a distributed switch, as it simplifies the process and ensures proper configuration.
- C. Correct.
Correct: Assigning uplinks (physical NICs) ensures that the hosts have physical connectivity to the distributed switch. Without this, network traffic cannot flow.
- D. Incorrect.
Incorrect: Manually configuring each ESXi host's network settings is not efficient or scalable. The distributed switch is designed to centralize and simplify network configuration management.
- E. Correct.
Correct: Ensuring compatibility between the distributed switch version and ESXi host version is critical for proper functionality and to avoid issues when adding the host to the switch.
