問題文
A DBA adds a second private network interface to every node so that the interconnect survives the loss of one interface. Which statement describes what the clusterware does with the additional interface?
選択肢
- It bonds the two interfaces into one logical interface at the operating system level, so the clusterware sees a single address and the failure of one interface is invisible to it.
- It creates highly available addresses on the interfaces that carry the private role, and moves an address to a remaining interface when one fails.
- It uses the additional interface solely for the traffic of the storage layer, and the database instances keep using the first one throughout.
- It records the additional interface in the registry, but leaves it idle until an administrator changes the parameter that names the interconnect of each instance.
