2V0-21.23 Question 273
Select 2An administrator is tasked with configuring time synchronization for a vSphere environment. The environment includes several ESXi hosts and a vCenter Server. The administrator wants to ensure that all ESXi hosts are using the same time source and are synchronized. Which steps should the administrator take to accomplish this?
- A
Configure an NTP server on the vCenter Server and enable time synchronization for all ESXi hosts via vSphere Client.
- B
Manually configure each ESXi host to use an external NTP server and enable periodic synchronization.
- C
Enable host time synchronization with vCenter Server on all ESXi hosts.
- D
Synchronize the vCenter Server’s time with an external NTP server.
- E
Manually adjust the time on each ESXi host to match the current time of the vCenter Server.
Show answer and explanation
Correct answers: A, D
Explanation
To ensure consistent and accurate time synchronization across a vSphere environment, the vCenter Server should be configured to synchronize with an external NTP server. Additionally, ESXi hosts should be configured to synchronize their time with the vCenter Server or a central NTP server. This approach simplifies management and reduces the risk of time drift across the environment.
- A. Correct.
Correct: Configuring an NTP server on the vCenter Server and enabling time synchronization for ESXi hosts ensures that all hosts receive time updates from a central source.
- B. Incorrect.
Incorrect: Manually configuring each ESXi host to use an external NTP server is error-prone and does not ensure centralized management. This approach is not best practice.
- C. Incorrect.
Incorrect: Enabling host time synchronization with vCenter Server is not recommended because vCenter Server itself needs to rely on a reliable time source like an NTP server.
- D. Correct.
Correct: Synchronizing the vCenter Server’s time with an external NTP server ensures that the vCenter Server has an accurate and consistent time source.
- E. Incorrect.
Incorrect: Manually adjusting the time on ESXi hosts is not scalable or reliable and can lead to inconsistencies over time.
