2V0-21.23 Question 61
Select 3An organization is planning to deploy a new vSphere Distributed Switch (VDS) across multiple ESXi hosts to standardize network configurations. After creating the VDS, the administrator needs to migrate virtual machine (VM) networking from the current Standard Switches (VSS) to the VDS with minimal downtime. Which steps should the administrator take to achieve this?
- A
Ensure the VDS and port groups are properly configured before starting the migration.
- B
Migrate the management network of the ESXi hosts to the VDS first to verify connectivity.
- C
Use the 'Add and Manage Hosts' wizard to migrate VM network adapters to the VDS.
- D
Create a backup of the current network configuration before starting the migration process.
- E
Manually reconfigure each VM to use the VDS port groups after the migration is complete.
Show answer and explanation
Correct answers: A, C, D
Explanation
To migrate VM networking from Standard Switches (VSS) to a vSphere Distributed Switch (VDS) with minimal downtime, administrators must first configure the VDS and port groups correctly, ensuring they match the existing network configuration. Using the 'Add and Manage Hosts' wizard provides a streamlined way to migrate VM network adapters. Additionally, creating a backup of the network configuration ensures that the administrator can restore the previous state if issues arise. Avoid migrating the management network first and manual reconfigurations, as these steps can introduce unnecessary risks and effort.
- A. Correct.
Ensuring the VDS and port groups are properly configured before migration is critical to avoid misconfigurations and ensure a seamless transition.
- B. Incorrect.
Migrating the management network first could lead to a loss of connectivity if there are configuration errors. This step is not recommended as the first action.
- C. Correct.
Using the 'Add and Manage Hosts' wizard is the recommended approach for migrating VM network adapters to the VDS as it simplifies and automates the process.
- D. Correct.
Creating a backup of the current network configuration is a best practice to ensure recovery options in case of any issues during the migration.
- E. Incorrect.
Manually reconfiguring each VM is not necessary as the migration process can automatically map the VMs' network adapters to the VDS port groups.
