Final answer:
Administrative share names on Windows operating systems are indicated by the dollar sign symbol ($), marking them as hidden shares accessible only by administrators. So, the correct answer is B. $.
Step-by-step explanation:
Administrative share names on Windows operating systems are most commonly designated by which of the following symbols?
The correct answer is B. $.
Administrative shares are special shares that are created automatically by the Windows operating system.
These shares are not visible in the network browsing tools but can be accessed by those who have administrative permissions and know the share exists.
For example, if a computer has a hard drive with the letter C, the administrative share for the root of the C drive would be shared as C$.
Similarly, the administrative shares for printers would be designated with a $ after the share name, such as PRINTER$.
The dollar sign at the end of the share name is what signifies it as an administrative, or 'hidden', share and not a standard network share that is openly advertised for users to connect to.
So, the correct answer is B. $.
