Also Microsoft says : you need not know .Net for this certification and proceed to ask questions deep in the dark corners of .Net libraries

The requirement says "Receipt data must always be encrypted at rest." That might make a person think do not use client side encryption. But then proceeds to make the person guess from the answer choices that it is client side encryption. Why does this organization think this is a good way to ask questions?

"Consider using service-side encryption features instead of client-side encryption. For more information about service-side encryption features, see Azure Storage encryption for data at rest."

To be honest, if you are an experienced programmer you can guess the right answer to this question by pure logic, no .Net code or even Azure knowledge is needed.

Exactly! Did it from 1st try, but originally was very confused with plenty of optins, LOL. So, 2nd and 3rd steps are easy to connect. And in 2nd step you should use "key" from Step1, but it only occurs in options 3 and 4. Since, 4 is about deletion policy, which doesn't make sense - then go with 3 which is Encryption Policy. And Encryption Policy is 1:1 mapping to last step 3 :)

BlobEncryptionPolicy accept "Ikey" on constructor => https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.storage.blob.blobencryptionpolicy.-ctor?view=azure-dotnet-legacy#Microsoft_Azure_Storage_Blob_BlobEncryptionPolicy__ctor_Microsoft_Azure_KeyVault_Core_IKey_Microsoft_Azure_KeyVault_Core_IKeyResolver_ (keyBundle.Key return a Microsoft.Azure.KeyVault.WebKey.JsonWebKey). The answer is correct !

1. var key = keyBundle.Key; 2. var x = new BlobEncryptionPolicy(key, resolver); 3. cloudBlobClient.DefaultRequestOptions.EncryptionPolicy = x; But I'm afraid I've wasted my time. As you can see in the links, it's all legacy code. https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.keyvault.keyvaultclientextensions.getkeyasync?view=azure-dotnet-legacy&viewFallbackFrom=azure-dotnet https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.storage.blob.blobencryptionpolicy.-ctor?view=azure-dotnet-legacy#Microsoft_Azure_Storage_Blob_BlobEncryptionPolicy__ctor_Microsoft_Azure_KeyVault_Core_IKey_Microsoft_Azure_KeyVault_Core_IKeyResolver_ https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.storage.blob.blobrequestoptions.encryptionpolicy?view=azure-dotnet-legacy#Microsoft_Azure_Storage_Blob_BlobRequestOptions_EncryptionPolicy

This is NOT correct, keyBundle.Key() is correct, it is a method, not a property, so no correct

No, it's a property. Read documenation. https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.keyvault.models.keybundle.key?view=azure-dotnet-legacy#Microsoft_Azure_KeyVault_Models_KeyBundle_Key
