SG0-001 · Question #147

Multiple SAN-attached LUNs are allocated to a host. The LUNs are then mapped to the operating system as a single disk by which of the following?

The correct answer is D. Logical Volume Manager. A Logical Volume Manager (LVM) is used to combine multiple SAN-attached LUNs into a volume group, from which logical volumes can be created and presented to the operating system as a single disk.

Why each option

A Logical Volume Manager (LVM) is used to combine multiple SAN-attached LUNs into a volume group, from which logical volumes can be created and presented to the operating system as a single disk.

AMount Point

A mount point is a directory where a file system is attached; it does not combine multiple underlying LUNs into a single logical disk.

BFile System

A file system organizes data on a single logical volume or partition; it does not consolidate multiple LUNs into one.

CVolume Group

A volume group is a component of LVM that aggregates physical volumes, but the overall system responsible for mapping these to the OS as a single disk is the Logical Volume Manager itself.

DLogical Volume ManagerCorrect

A Logical Volume Manager (LVM) allows for the aggregation of multiple physical volumes, such as SAN-attached LUNs, into volume groups, from which logical volumes can be created and presented to the operating system as a single, flexible storage entity.
