A vSphere environment is configured with 1 Gigabit Ethernet for vSphere vMotion.
The application team is complaining that when they try to migrate a powered-on virtual machine, the progress is slow and unsuccessful the majority of the time.
Which two recommendations should the administrator make to improve vSphere vMotion performance? (Choose two.)

The current configuration of the vSphere environment with only 1 Gigabit Ethernet for vSphere vMotion is causing performance issues during the migration of powered-on virtual machines. To improve vSphere vMotion performance, the administrator should consider the following recommendations:
Use at least two port groups: Using multiple port groups will enable the vSphere vMotion traffic to be load-balanced across the available network interfaces, resulting in better performance. When multiple port groups are used, vSphere vMotion selects the port group with the least amount of traffic, reducing the chances of network congestion.
Use 10 Gigabit Ethernet or above: Upgrading the network to 10 Gigabit Ethernet or higher will provide a significant boost in performance as it will increase the available bandwidth. This will allow for faster and more efficient vSphere vMotion operations, resulting in less downtime and a better user experience.
Other possible recommendations that could improve vSphere vMotion performance but were not listed in the answers include:
Enabling jumbo frames: Jumbo frames increase the maximum transmission unit (MTU) size of network packets, which can reduce the overhead associated with vSphere vMotion traffic and improve performance.
Adjusting the vSphere vMotion TCP/IP settings: Changing the TCP/IP settings for vSphere vMotion, such as increasing the maximum segment size (MSS) or adjusting the window size, can also help improve performance.
Using a dedicated network for vSphere vMotion: By using a separate network specifically for vSphere vMotion traffic, the administrator can reduce the chances of congestion and interference from other network traffic, resulting in improved performance.
Using hardware acceleration: Some network adapters and switches support hardware acceleration for vSphere vMotion traffic, which can significantly improve performance.
In summary, using multiple port groups and upgrading the network to 10 Gigabit Ethernet or above are two key recommendations that can improve vSphere vMotion performance in a scenario where the application team is experiencing slow and unsuccessful migrations.
