DS0-001 Question #137: Real Exam Question with Answer & Explanation

Question

An analyst shared a database directly from a workstation. A week later, users could not access the database, but could access other shared resources. Which of the following is the most likely reason the shared database is unavailable?

Options

• AThe IP addresses for the sharing workstation changed.
• BThe DNS changed the workstation's name.
• CThe IP addresses for the users' workstations changed.
• DThe DNS permissions changed.

Explanation

When a database is shared directly from a workstation, clients connect to it using that workstation's IP address. Workstations typically receive dynamic IP addresses via DHCP, meaning the address can change - and when it does, any connection mapped to the old IP breaks, making that specific share inaccessible while other resources (on different hosts with stable addresses) continue to work fine.

Why the distractors are wrong:

• B (DNS name change): DNS name changes are rare administrative events and would disrupt name-based access broadly, not just one share - and the question specifies other resources still work.
• C (Users' IPs changed): Client IP changes don't affect the client's ability to reach a server; only the host's IP matters for incoming connections.
• D (DNS permissions changed): DNS permissions control name resolution, not share-level access, and again would affect connectivity more broadly than a single resource.

Memory tip: Think "the server must be findable." When sharing a resource, the host's address must be stable - workstations with DHCP are poor file servers precisely because their IP can vanish and reappear elsewhere. This is why dedicated servers use static IPs or DHCP reservations.
