An administrator has been notified that a number of hosts are not compliant with the company policy for time synchronization.
The relevant portion of the policy states:
All physical servers must synchronize time with an external time source that is accurate to the microsecond.
Which step should the administrator take to ensure compliance with the policy?
To ensure compliance with the company policy that requires all physical servers to synchronize time with an external source accurate to the microsecond, each ESXi host should be configured to use a Precision Time Protocol (PTP) source. PTP is designed to provide time synchronization with higher precision and accuracy to the microsecond level, whereas Network Time Protocol (NTP) typically provides synchronization accuracy to the millisecond level, which does not meet the policy requirements.
B - Question is asking for microsecond PTP does Microsecond NTP does Millesecond https://blogs.virtualmaestro.in/2020/04/11/timekeeping-in-vsphere-7-0-ntp-or-ptp/
Answer should be B for PTP for microsecond accuracy. NTP is not accurate to that level
for sure b
PTP is accurate to the microsecond.
B: All physical servers must synchronize time with an external time source that is accurate to the microsecond. NTP is milliseconds.
This was my answer, passed with 452
The question quotes that the TIME SOURCE should be accurate to the microsecond. It don't says that the host must follow this source with a microsecond accuracy C should match the policy.
NTP provides millisecond timing accuracy and PTP maintains microsecond timing accuracy.
Resposta: B PTP: microssegundos e NTP: milissegundos
Answer is C. Difference between NTP and PTP: NTP allows for precision within milliseconds, PTP allows for precision within nanoseconds
