This LPIC-2 practice question tests your understanding of file sharing and samba. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO parameters in the [global] section are REQUIRED for a Samba server to act as a standalone server (not a member of a domain)?
server string
Why wrong: Incorrect; purely descriptive.
workgroup
Correct; must be set to define the workgroup.
security = user
Correct; necessary for standalone authentication.
netbios name
Why wrong: Incorrect; optional, defaults to hostname.
passdb backend = tdbsam
Why wrong: Incorrect; default is tdbsam, so not required to be explicitly set.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
workgroup
For a Samba standalone server, the `workgroup` parameter defines the NetBIOS workgroup name that the server will appear in, which is essential for browsing and identification on the local network. The `security = user` parameter is required because it sets the server to authenticate users locally against its own passdb backend, rather than relying on an external domain controller. Without these two, the server cannot function as a standalone unit.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that candidates often think `passdb backend` must be explicitly set (like `tdbsam`) or that `netbios name` is mandatory, but Samba's defaults handle these, while `workgroup` and `security = user` are the true non-negotiable parameters for standalone operation.
Detailed technical explanation
Under the hood, `security = user` forces Samba to use its own authentication stack (via `smbd`) to validate credentials against the local passdb, which is essential for standalone servers that do not contact a domain controller. The `workgroup` parameter sets the NetBIOS scope ID for browsing; without it, the server would default to 'WORKGROUP' but explicitly defining it ensures correct visibility in network neighborhood lists. In real-world scenarios, misconfiguring `workgroup` can cause clients to fail to discover the server, even if authentication works.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the LPIC-2 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
