CompTIA Linux+ XK0-006 (V8) Practice Question

During performance tuning of an ext4 data partition on a busy read-heavy application server, you discover that read operations still cause small writes because the filesystem updates each inode's last access time (atime). You remount the partition with the noatime option to remove this overhead. Which statement correctly describes what will happen after the option is applied?

  • Access-time updates are kept only in memory and flushed to disk during sync or fsync operations.

  • Inode access times for both files and directories will no longer be written when the files are read, eliminating those read-triggered writes.

  • Only directory inodes stop recording access times; regular file atime updates still occur.

  • Access times continue to be written, but only if they are older than the file's modification/change time or more than 24 hours old.
