質問 # 55
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?
- A. Ensure that each ESXi host is configured to use a Network Time Protocol (NTP) source.
- B. Ensure that each ESXi host is configured to use a Precision Time Protocol (PTP) source.
- C. Ensure that each vCenter Server Appliance is configured to use a Network Time Protocol (NTP) source.
- D. Ensure that each vCenter Server Appliance is configured to use a Precision Time Protocol (PTP) source.
正解：B
解説：
Explanation
To comply with the policy of synchronizing time with an external source that is accurate to the microsecond, the administrator needs to ensure that each ESXi host is configured to use a PTP source, which provides higher accuracy than NTP.

質問 # 68
Which feature would allow for the non-disruptive migration of a virtual machine between two clusters in a single VMware vCenter instance?
- A. Cross vCenter Migration
- B. vSphere Fault Tolerance
- C. vSphere Storage vMotion
- D. vSphere vMotion
正解：D
解説：
vSphere vMotion allows for the non-disruptive migration of a virtual machine between two clusters in a single vCenter instance, as long as there is shared storage and network connectivity between the clusters.
Reference:
vMotion is used to move the VM to a different cluster within the same vCenter. This only works if both clusters share the same storage. If they don't you also need to perform a Storage vMotion. Cross vCenter Migration is only used to migrate to a different vCenter.
質問 # 69
During the staging of a patch on a vCenter Server Appliance, an error was encountered and the process stopped. An administrator resolved the root cause and is ready to continue with the staging of the patch.

- B. Use the Resume option to resume the staging.
- C. Use the Stage and Install option to resume the staging.
- D. Use the Stage Only option to restart the staging.
正解：C
解説：
Explanation
Option A is correct because it allows the administrator to resume the staging of the patch using the Stage and Install option in the vCenter Management Interface, which will continue the process from the point at which the error occurred. Option B is incorrect because there is no Resume option in the vCenter Management Interface. Option C is incorrect because it will unstage the patch and restart the staging from the beginning.
Option D is incorrect because it will restart the staging from the beginning and not install the patch.

An administrator plans to update the Supervisor cluster and has noticed some of the Tanzu Kubemetes Grid clusters are running an incompatible version.
Which action must the administrator take before proceeding with the Supervisor cluster update?
- A. No action is needed - Tanzu Kubernetes Grid clusters will be updated automatically as part of the update process.
- B. Update incompatible Tanzu Kubernetes Grid clusters prior to the Supervisor cluster update.
- C. No action is needed - Incompatible Tanzu Kubernetes Grid clusters can be manually updated after the Supervisor cluster update.
- D. Update all Tanzu Kubernetes Grid clusters to the latest version prior to the Supervisor cluster update.
正解：B
解説：
Explanation
Option D is correct because it indicates that the administrator must update incompatible Tanzu Kubernetes Grid clusters prior to the Supervisor cluster update, as this will ensure that there are no compatibility issues or disruptions during or after the update process. Option A is incorrect because it is not necessary to update all Tanzu Kubernetes Grid clusters to the latest version prior to the Supervisor cluster update, as some clusters may already be compatible with the new version. Option B is incorrect because Tanzu Kubernetes Grid clusters will not be updated automatically as part of the update process, as they require manual intervention from the administrator. Option C is incorrect because incompatible Tanzu Kubernetes Grid clusters cannot be manually updated after the Supervisor cluster update, as they may become inaccessible or unstable due to compatibility issues.

A VMkernel port is labelled PROD01 and uses the default TCP/IP stack. Currently, this VMkernel port is configured for supporting live virtual machine (VM) migrations.
Which configuration change should the administrator make to isolate live VM migration traffic from other network traffic?
- A. Modify PROD01 by changing the TCP/IP stack to vSphere vMotion.
- B. Create a new VMkernel port and set the TCP/IP stack to provisioning.
- C. Remove PROD01 and create a new VMkernel port with the TCP/IP stack set to provisioning.
- D. Remove PROD01 and create a new VMkernel port and set the TCP/IP stack to vSphere vMotion.
正解：A
解説：
Explanation
The configuration change that should be made to isolate live VM migration traffic from other network traffic is to modify PROD01 by changing the TCP/IP stack to vSphere vMotion, which allows dedicating a separate stack for vMotion traffic and disabling it from the default TCP/IP stack.
