LFCS Question #616: Real Exam Question with Answer & Explanation

Question

Which command typed on a Samba 3 server will print out the local SID?

Options

• Anet get sid localhost
• Bnet getlocalsid
• Cnet getsid
• Dnet rpc get localsid

Explanation

On a Samba 3 server, the net getlocalsid command is used to display the Security Identifier (SID) assigned to the local Samba domain.

Common mistakes.

• A. While net get sid is a valid command, it typically requires an argument to specify the target (e.g., a domain or user SID), and localhost might not explicitly yield the domain SID without further context, unlike the direct getlocalsid.
• C. net getsid is an incomplete command and lacks the necessary arguments or context to specify that it should retrieve the local domain SID.
• D. net rpc get localsid is not the correct syntax for retrieving the local SID; the rpc subcommand is generally used for remote procedure calls, not direct local SID retrieval.

Concept tested. Samba local SID retrieval
