220-802 Question #507: Real Exam Question with Answer & Explanation

The correct answer is A: Defragmentation. When a large number of files (like photos) are added to a traditional spinning hard drive (HDD), the file system often writes them in non-contiguous fragments scattered across the disk. This fragmentation forces the read/write head to physically travel greater distances to reasse

Question

A user reports slow performance on their PC after importing some photos. Which of the following maintenance tasks should a technician recommend in order to increase performance?

Options

ADefragmentation
BInstall new camera drivers
CUpdate anti-virus definitions
DRun CHKDSK

Explanation

When a large number of files (like photos) are added to a traditional spinning hard drive (HDD), the file system often writes them in non-contiguous fragments scattered across the disk. This fragmentation forces the read/write head to physically travel greater distances to reassemble files, slowing performance. Defragmentation reorganizes these fragmented files into contiguous blocks, reducing seek time and improving speed. Installing camera drivers (B) affects device communication, not storage speed. Updating antivirus definitions (C) improves threat detection, not performance. CHKDSK (D) repairs file system errors but does not optimize file layout or improve read performance.
