SY0-301 · Question #231

A system administrator is responding to a legal order to turn over all logs from all company servers. The system administrator records the system time of all servers to ensure that:

The correct answer is D. time offset can be calculated. When collecting server logs for legal proceedings, recording each server's local system time allows investigators to calculate the time offset from a reference standard, enabling accurate correlation of events across multiple systems.

Question

A system administrator is responding to a legal order to turn over all logs from all company servers. The system administrator records the system time of all servers to ensure that:

Options

  • AHDD hashes are accurate.
  • Bthe NTP server works properly.
  • Cchain of custody is preserved.
  • Dtime offset can be calculated.

Why each option

When collecting server logs for legal proceedings, recording each server's local system time allows investigators to calculate the time offset from a reference standard, enabling accurate correlation of events across multiple systems.

AHDD hashes are accurate.

HDD hashes verify the integrity of disk images and are unrelated to recording system time.

Bthe NTP server works properly.

Verifying NTP server functionality is a network maintenance concern, not the purpose of recording system time during evidence collection.

Cchain of custody is preserved.

Chain of custody refers to the documented handling and transfer of evidence, not to the act of recording server system times.

Dtime offset can be calculated.Correct

Different servers may have their clocks set incorrectly or drifted from standard time. By documenting each server's system time at the moment of collection, investigators can calculate the offset from a reference time (such as UTC or an NTP source) and accurately reconstruct the true sequence of events across all collected logs.
