A. B. C. D.Answer - C.
This is given in the AWS documentation.
If users will access their WorkSpaces through a virtual private network (VPN), the connection must support a maximum transmission unit (MTU) of at least 1200 bytes.
For more information on AWS Workspaces networking requirements, please refer to the below URL:
http://docs.aws.amazon.com/workspaces/latest/adminguide/workspaces-network-requirements.htmlThe correct answer is D. 1500.
MTU (Maximum Transmission Unit) refers to the maximum size of an IP packet that can be transmitted over a network. It includes the IP header, the TCP or UDP header, and the data payload.
When a VPN connection exists between an on-premise facility and AWS, it is important to ensure that the MTU is properly configured to prevent packet fragmentation, which can result in reduced network performance.
Workspaces are a cloud-based virtual desktop service provided by AWS. When a Workspace is launched, it establishes a VPN connection to the customer's VPC (Virtual Private Cloud) using the AWS Client VPN service.
The recommended MTU size for AWS VPN connections is 1500 bytes. This is the default MTU size for Ethernet networks and is compatible with most on-premise networks. In some cases, a smaller MTU size may be necessary to avoid packet fragmentation, but this is not recommended as it can reduce network performance.
In summary, the minimum amount of MTU which should be supported by the connection between an on-premise facility and AWS when using Workspaces is 1500 bytes (Option D).
