You want to enable resumable space allocation at the instance level. Which two actions would enable resumable space allocation at the instance level? (Choose two.)
A. issuing the ALTER SYSTEM ENABLE RESUMABLE; statement
B. issuing the ALTER SESSION ENABLE RESUMABLE; statement
C. modifying the RESUMABLE_TIMEOUT initialization parameter to a nonzero value
D. issuing the ALTER SYSTEM SET RESUMABLE_TIMEOUT=<nonzero value>; statement

RESUMABLE_TIMEOUT设为非零，避免空间不够的原因导致session failed，设置RESUMABLE_TIMEOUT为非零时会等待分配新的空间继续工作。
