You have a server named Server1 that runs Windows Server 2016. You install the Docker daemon
on Server1. You need to configure the Docker daemon to accept connections only on TCP port
64500. What should you do?

A.
Run the New-NetFirewallRule cmdlet

B.
Run the Set-ServiceWindows PowerShell cmdlet

C.
Edit the daemon.json file

D.
Edit the configuration.json file

Explanation:
Configure Docker with Configuration File. The preferred method for configuring the Docker Engine
on Windows is using a configuration file. The configuration file can be found at
‘c:\\ProgramData\\docker\\config\\daemon.json’. Only the desired configuration changes need to be
added to the configuration file. For example, this sample configures the Docker Engine to accept
incoming connections on port 64500. All other configuration options will use default values.

“hosts”: [“tcp://0.0.0.0:64500”]
