問題文
How do the dashboard, the command line client and the service interfaces relate to each other?
選択肢
- The dashboard writes directly to the databases of each service while the command line client goes through the service interfaces, which is why a change made in one of them can take a considerable time to become visible in the other and may need a refresh of the underlying records before it appears.
- The command line client is the only way to reach some services, because the dashboard has no access to them, so a change made from a terminal could stay hidden from the web pages.
- All of them are clients of the same service interfaces, so an action taken in one is visible from the others.
- The dashboard replaces the service interfaces once it is installed, which leaves a script with nothing to call as soon as an operator deployed the web pages.
