問題文
A primary already sends redo to a nearby standby and the business now wants a third copy at a distant site without adding load to the primary. Which arrangement meets that constraint?
選択肢
- The nearby snapshot standby forwards the redo it receives to the distant member so the primary keeps a single destination to serve
- The nearby logical standby forwards the redo it receives to the distant member so the primary keeps a single destination to serve
- The nearby physical standby forwards the redo it receives on to the distant member so the primary keeps a single destination to serve
- The distant member pulls the redo it needs from the nearby standby so the primary keeps a single destination while forwarding stays unconfigured
