A moss-garden festival ticket scan must persist booth=north and day=sat on an image blob without changing the image bytes. Which Blob SDK action should the developer take?
Select an answer to reveal the explanation.
Short Explanation
Stick booth and day on the blob like luggage tags—metadata—without rewriting the photo. That is set/retrieve user metadata, not a Cosmos detour and not “metadata cannot do custom keys.”
Full Explanation
User-defined metadata lets applications attach name-value pairs to a blob without modifying the blob’s data stream. Overwriting bytes to embed labels is unnecessary. Cosmos items and blob index tags are different storage/filter surfaces; this skill targets set and retrieve of blob metadata.
