issue with .cer certificate

I have generated a ValidationCertification.cer file. I now want to upload it and verify the certificate, without going to the Azure Portal.

az iot dps certificate verify only has and example for a .pem file. Can I not use this command with the .cer file?

Nb: tried that and got:

PS C:\temp> azsphere tenant download-validation-certificate --output ValidationCertification139.cer --verificationcode CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC

Saving the validation certificate to 'C:\temp\ValidationCertification139.cer'.
Saved the validation certificate to 'ValidationCertification139.cer'.

PS C:\temps> az iot dps certificate verify --dps-name $DPSName --resource-group $GroupName --name MyCertificate137 --path ValidationCertification139.cer --etag AAAAAALTXUo=

Invalid ETag supplied. If you contact a support representative please include this correlation identifier: 48ab965d-7916-46e9-9856-61745accce7a, timestamp: 2020-04-21 05:39:59Z, errorcode: IH412001.

The etag used was from the earlier az iot dps certificate create command and used in the az iot dps certificate generate-verification-code command.

{
  "etag": "AAAAAALTXUo=",
  "id": "/s
