問題文
A company has chosen Tableau Cloud. Several of its databases sit inside a private network that the site cannot reach, and the extracts built on them must refresh on a schedule. Which component makes those scheduled refreshes possible?
選択肢
- An external gateway, which is installed inside the private network and forwards the site requests so the databases stay closed.
- Tableau Bridge, which is installed inside the private network and polls the site for refresh work so the databases never need an inbound opening.
- An unlicensed node, which is installed inside the private network and runs the refresh work for the site.
- A coordination ensemble, which is installed inside the private network and keeps the site state so the refreshes can be scheduled.
