An administrator logs into the VMware NSX Manager UI and discovers a time sync issue that has been reported in the VMWare Cloud Foundation (VCF) installer.
The administrator performs the following steps:
1. Validates that the NTP server IP addresses are present in the NTP configuration on the VCF Installer.
2. Validates that the DNS records are correctly set for the FQDN and IP address of the two NTP servers.
3. Validates that the NTP servers can be pinged by name and IP address from the VCF Installer.
4. Validates that the time between the NTP servers and the VCF Installer is synchronized successfully.
What additional step should the administrator perform to help identify the cause of the error?

• A.Confirm that the ESX hosts have been configured to use host time synchronization.
• B.Confirm that the NTP service has an allowed rule in the iptables on the VCF Installer.
• C.Confirm that the time on the ESX hosts allocated for the management domain is synchronized with the same NTP servers as the VCF Installer.
• D.Confirm that the NTP server details have been specified in the deployment parameter workbook using the required FQDN format.

An administrator is troubleshooting network connectivity issues on a VMware ESX host configured with a dedicated VMware vSAN vSphere Distributed Switch (vDS) port group. The VMware vSAN vDS port group has two physical adapters and two uplinks assigned. After a failure of the active physical adapter, the vSAN vDS connection over the vSAN network was lost.
What is the cause of the issue?

• A.VLAN tagging is not correctly configured on the vDS.
• B.The vDS failover policy does not allow fallback.
• C.The vSAN storage policies are misconfigured.
• D.A physical adapter is set to "Not Used" in the vDS configuration.

An administrator attempts to update the VMware vCenter root account password through VMware Cloud Foundation (VCF) Operations. The attempt fails with the following error message, "Failed to authenticate with the guest operating system using the supplied credentials." What is the cause of the failure?

• A.The password does not meet policy requirements.
• B.The password was previously updated on the vCenter directly.
• C.vCenter is down.
• D.The SSH service is not running.

An administrator creates a tag for a virtual machine (VM) in VMware Cloud Foundation (VCF) Operations.
When assigning the tag to the virtual machine In vCenter, the tag was not found.
What is the cause of this error?

• A.VM Tools is not installed.
• B.The tag was not pushed to the vCenter instance.
• C.The tag was not pushed to Custom Groups.
• D.The vCenter version is incorrect.

An administrator discovers that a VMware Cloud Foundation (VCF) workload domain four-node vSAN cluster is experiencing a network partition. The workload domain vCenter displays a "vSAN duster partition" warning. The performance across the cluster is degraded and the objects are showing as non-compliant.
What could be causing the network partition?

• A.Jumbo frames are configured on the vSphere distributed switch (VDS).
• B.IGMP snooping is disabled on the multicast group.
• C.The vSAN Witness service was added to the vMotion network.
• D.The VLAN was changed on the physical switch port.
