Part of the procedure for decommissioning a database server is to wipe all local disks, as well as SAN LUNs allocated to the server, even though the SAN itself is not being decommissioned. Which of…

Question

Options

• ALUN masking will prevent the next server from accessing the LUNs.
• BThe data may be replicated to other sites that are not as secure.
• CData remnants remain on the LUN that could be read by other servers.
• DThe data is not encrypted during transport.

• A
  3% (1)
• B
  6% (2)
• C
  88% (30)
• D
  3% (1)

Explanation

When a Storage Area Network (SAN) Logical Unit Number (LUN) is released from one server and later reallocated to another, the data written by the previous server still physically exists on the storage media. LUN masking controls which servers can see which LUNs at a given time, but once a LUN is reassigned, the new server can read the leftover data remnants from the old server. Wiping the LUN before reassignment eliminates this risk. Option A is incorrect because LUN masking is a preventive control that no longer applies once the LUN is reassigned. Option B describes a replication risk that is separate from the decommissioning process. Option D relates to data-in-transit encryption, not data-at-rest remnants.
