問題文
A team wants to record the identifier that their incident management tool uses for a service, so that a plugin can link to the right schedule. Which part of metadata is intended for references into external systems?
選択肢
- annotations, whose purpose is mainly to reference external systems.
- links, which point at web pages for humans and at the systems that own them.
- labels, because they are key and value pairs and are therefore the place for any structured identifier that another system needs to look the entity up by.
- tags, which are single-valued strings.
