Which command is used to mount a DVD-ROM to a media directory?

1. mount /media/dvd /dev/dvd

2. mount -t iso9660 /dev/dvd /media/dvd

3. mount /dev/dvd /media/dvd

4. mount /media/cdrom /dev/cdrom

The correct answer is: mount /dev/dvd /media/dvd

The command used to mount a DVD-ROM to a media directory is correctly identified as the one that specifies the device to be mounted followed by the target mount point. In this case, the command indicates that the DVD device located at `/dev/dvd` is to be mounted to the directory located at `/media/dvd`. This is the standard form for the mount command, which involves specifying the device and the mount point, allowing the operating system to access the contents of the DVD. In a typical Linux environment, `/dev/dvd` is usually a symlink to the actual device file representing the DVD drive, making it straightforward for the system to locate and mount the media. The mount point, `/media/dvd`, is a commonly used directory provided for accessing removable media. The other options include unnecessary or incorrect components. For instance, specifying the filesystem type with `-t iso9660` is not mandatory if the system can automatically identify the type of the filesystem present on the DVD. Additionally, some options involve alternative directories for mounting or a misunderstanding of the devices involved, which do not conform to the typical structure expected for mounting a DVD-ROM. Thus, the clarity and simplicity of using the direct device and media path make the chosen answer the most
