AWS WorkSpaces is a managed, secure cloud-based virtual desktop infrastructure (VDI) service that enables end-users to access the documents, applications, and resources they need from any supported device.

To ensure that AWS WorkSpaces functions properly, the following port numbers need to be open:

A. Port 443 - HTTPS (Hypertext Transfer Protocol Secure) port is used to provide secure communication over the internet between the client device and the AWS WorkSpaces infrastructure. This port must be open to enable access to the WorkSpaces management console and the WorkSpaces client software.

B. Port 22 - Secure Shell (SSH) port is used to provide secure remote access to the WorkSpaces instance. This port is used to manage WorkSpaces through an SSH client.

C. Port 53 - Domain Name System (DNS) port is used to resolve domain names to IP addresses. AWS WorkSpaces uses DNS to locate resources in the VPC (Virtual Private Cloud) environment, including the WorkSpaces directory service.

D. Port 80 - HTTP port is not required for AWS WorkSpaces to function properly. This port is used for unencrypted communication over the internet and is not recommended for use with WorkSpaces.

Therefore, the correct answers are A, B, and C.
