Your hard disk was partitioned in such a way that each cluster is 32KB. There was originally a file on the system that occupied seven clusters, but it was erased. The OS has now reclaimed one of those clusters with a 610 byte file. How would you best describe that particular cluster now? (For the purposes of this question, ignore binary calculations.)

The cluster would have 610 bytes of data and 31,390 bytes in the slack space

Explanation:

A cluster in a hard disk is the smallest possible unit of storage on a hard disk forming a group of sectors within a disk for allocation of files and directories. Each cluster in a hard disk is unique having its own ID.  Storing small files on a hard disk with large clusters will therefore waste disk space. This wasted disk space is called slack space.

Since each cluster has 32 KB space = 32 × 1000 bytes = 32000 bytes.

A 610 byte file is the stored in a cluster, Therefore since each cluster has a space of 32000 bytes they would be a wasted space of (32000 - 610 = 31390 bytes).  The cluster would have 610 bytes of data and 31,390 bytes in the slack space
