A group of new virtual machines have been deployed using thin-provisioned disks due to the limited storage space available in an environment. The storage team has expressed concern about extensive use of this type of provisioning.
An administrator is tasked with creating a custom alarm to notify the storage team when thin provisioning reaches a certain capacity threshold.
Where must the administrator define this alarm?
To create an alarm for thin provisioning reaching a certain capacity threshold, the administrator must define the alarm at the Datastore level. This is where specific metrics related to datastore usage and capacity can be closely monitored. Defining the alarm at the datastore level ensures that the storage team's concerns are directly addressed by monitoring the actual storage unit where thin provisioning occurs.
A datastore cluster is not mentioned, so it should be creating the alarm on the datastore. Answer A
Datastore Cluster IS mentioned. Option "C"
where ?! Read the question again

I logged on to my vCenter and tried if I can created a disk provisioned alarm on datacenter object, but there is no such alarm on DC object. So the correct answer here is A: Datastore
tricky. But as the question do not mention a specific datastore we can consider that this alarm should work for all storage in the organisation. So I bet for answer B
I would choose B - Data center The description does not mention that all thin provisioned disks are located on the same datastore. Configuring it on the data center would cover all datastores in this datacenter.
buy why would the storage team be concerned about alerts on the data store? The ques mentions the alert is for storage team.
Why they would be concerned, is it's a storage team.. and they can expand a volume if need be.. also the question says a custom alarm to alert that team.. data center is the only method with email to do so?

The most effective way is setting one alarm on the DataCenter, covering for all Datastores
Question is not worded properly but will pick A. Datastore as it is documented. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-monitoring-performance/GUID-82933270-1D72-4CF3-A1AF-E5A1343F62DE.html#:~:text=Datastore%20usage%20on%20disk
Since no datastores are menthioned, the answer shoulb be "DATACENTER" cause all the DS will be monitored. Otherwise you should set the alarm manually for all DS.
You can create an alarm definition for "Datastore Disk Usage" under datacenter, datastore cluster and datastore and spread what you have triggered under a relevent target type which will be an appropriate child objects (for example "All datastore", "All datastore cluster" and the other type of objects because you will not find it the "Datastore Disk Usage" ). So i think the purpose of the question is not "where is it possible to configure" but how should it be configured. But if you choose "Datastore Cluster" it will monitor the aggregation of all the datastore and it will not be relevent because you can have the threshold triggered on datastore but it will not trigger the alarm defined under the datastore cluster. => "Datastore" Option A
Does that alert notify the "storage team" they may not have vsphere access.?
They do not need access, the alarm can be configured to send mails.

Alarm should be set on datastore.
You can't create "Datastore usage on disk" alert at Datacenter object level.
Yes, you are right. I tried it on my vCenter and found once you select DC object to create an alarm, the only 2 option for storage are rename type and not disk usage or datastore usage. So the answer is A: Datastore
You need to think about where you are creating the alarm and also the target type from drop-down. Create the alarm at the Datacenter level and select a target type of datastore. So for me, option B.
B is correct since it will cover all datastores.
In vSphere, custom alarms related to storage capacity are defined at the datastore level.
In vSphere, custom alarms related to storage capacity are defined at the datastore level.
There is a DataStore pre-build alarm named "Thin-provisioned volume capacity threshold exceeded". It is global. So it is more suitable for this case. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-monitoring-performance/GUID-82933270-1D72-4CF3-A1AF-E5A1343F62DE.html
B - for all DS in this DC A - yes but only for single DS
Answer A is correct. specifical location/object(Where) B is an method of 3 methods how to enable/disable A option We can set alarm to minitor datastore usage by using vSphere Web Client(Data center)/vSphere Client/vSphere PowerCLI https://kb.vmware.com/s/article/2076157#:~:text=Using%20the%20vSphere%20Web%20Client%3A%201%20Navigate%20to,Edit.%208%20Select%20the%20Enable%20this%20alarm%20option.
A is correct
Did it on my lab to verify the comments of others here and found that you 'Can' configure the alarm at the datacenter level, select Datastore as the target type, on the IF statement you can select Datastore disk usage as the operator and the percentage amount %, and set it to trigger either a warning or a critical alarm and then select either email, snmp trap or run a script.
