A tide-pool classroom app only needs Last-Modified and the module metadata before deciding whether to fetch a 2 GB clip. Which Blob SDK call should it make first?
Select an answer to reveal the explanation.
Short Explanation
Do not haul a 2 GB film reel across town just to read the label. Call Get Properties for Last-Modified and metadata first, then download only if needed. Properties retrieval is not a data download.
Full Explanation
The Blob SDK separates metadata and property retrieval from downloading blob content. Get Properties returns system properties such as Last-Modified along with user metadata without transferring the payload. Full downloads, leases, or recreating the blob are unnecessary when the app only needs headers and metadata to decide whether to fetch.
