問題文

An attempt to create a vector index fails on a database that has just been upgraded. Which configuration item has to be in place first?

選択肢

1. A separate tablespace for vectors has to be created because both index types keep their whole structure inside that tablespace.
2. A memory area for vectors inside the shared area has to be sized because the graph indexes live there and the partition indexes use it while they are built.
3. A separate service for vectors has to be registered because the index build runs through that service on a dedicated set of processes.
4. A memory area for vectors inside the program area has to be sized because the graph indexes live there and the partition indexes use it during the build.
