CV0-003 Question #327: Real Exam Question with Answer & Explanation
The correct answer is A: Implement Coordinated Universal Time on all workloads. Time drift on cloud VMs that was absent on-premises is resolved by standardizing all workloads to Coordinated Universal Time, ensuring a consistent and universal time reference across all distributed instances.
Troubleshooting
Question
A company has moved all on-premises workloads into a public cloud. After some time, the cloud engineer starts noticing time drifts on the VMs and suspects an NTP issue. Time drifts were not an issue when all the workloads were on-premises. Which of the following describes how the cloud engineer should resolve the issue?
Options
- AImplement Coordinated Universal Time on all workloads
- BPoint all workloads back to an on-premises NTP server
- CPoint all workloads to a stratum 2 within the public cloud provider
- DConfigure all of the VMs as NTP servers within the public cloud provider
Explanation
Time drift on cloud VMs that was absent on-premises is resolved by standardizing all workloads to Coordinated Universal Time, ensuring a consistent and universal time reference across all distributed instances.
Common mistakes.
- B. Routing cloud VM time synchronization through an on-premises NTP server introduces network latency, creates a dependency on the corporate WAN, and establishes a single point of failure for all cloud workload time synchronization.
- C. Pointing workloads to a cloud provider stratum 2 server addresses the NTP source but does not resolve drift caused by inconsistent time zone or time standard configurations across the VMs themselves.
- D. Configuring VMs as NTP servers is unreliable because VM clocks are themselves subject to drift and virtualization clock skew, making them unsuitable as authoritative time sources for other workloads.
