Docker is generally configured to use TCP port . . . . . . . . while executing unencrypted traffic

3306
53378
2375
2376

The correct answer is: C. 2375

Docker is generally configured to use TCP port 2375 while executing unencrypted traffic. This is the default port for the Docker daemon, which is the process that manages Docker containers.

Option A, 3306, is the default port for the MySQL database server. Option B, 53378, is the default port for the DNS server. Option D, 2376, is the default port for the Docker API.

The Docker API is a RESTful API that allows you to interact with Docker containers and images. It is not used for executing unencrypted traffic.
