Exam 2V0-21.23 topic 1 question 45 discussion

A datastore cluster is not mentioned, so it should be creating the alarm on the datastore. Answer A

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

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

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.

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.

B is correct since it will cover all datastores.

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.

A is correct

The most effective way is setting one alarm on the DataCenter, covering for all Datastores

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

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't create "Datastore usage on disk" alert at Datacenter object level.

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.

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

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.

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
