Your Answer
- 53
- 135

Correct Answer
3389
This answer is correct.
Incorrect - Port 53 is used by DNS for name resolution, which is not directly related to the Remote Desktop client.
Incorrect – Port 135 is used by the Microsoft Endpoint Mapper, also known as the DCE/RPC Locator service, which helps in assigning dynamic ports to services and is not directly related to the Remote Desktop client.
Incorrect – Port 3268 is used by the global catalog in Active Directory, which is not directly related to the Remote Desktop client.
Correct - Port 3389 is the default port for RDP, which is used by the Remote Desktop client to connect to a remote machine.
