Question

Options

• AUpload image file -> register image -> prepare image file -> use image to create cloud server
• BPrepare image file -> upload image file -> register image -> use image to create cloud server
• CRegister image -> upload image file -> prepare image file -> use image to create cloud server
• DPrepare image file -> register image -> upload image file -> use image to create cloud server

• A

• B

• C
  4% (1)
• D
  13% (3)

Explanation

Option B is correct because creating a system disk image from an external file follows a strict logical dependency chain: you must first prepare the image file locally (converting or formatting it to meet the platform's requirements), then upload it to cloud storage, then register it with the cloud platform so it becomes a usable image resource, and only then can you launch a cloud server from it. Option A is wrong because it places the upload step before preparation, meaning you would be uploading a file that does not yet exist or is not yet ready. Option C is wrong because it attempts to register an image before the file has even been uploaded, which is impossible since registration requires the file to already be present in cloud storage. Option D is wrong for the same reason as C - you cannot register an image before uploading it, since the registration process references the uploaded file.

Memory tip: Think of the workflow as a production line - you build the product (prepare), ship it to the warehouse (upload), log it in the inventory system (register), then sell it to the customer (create server). Each step depends on the previous one being complete.
