問題文
A site wants to distribute one prepared software directory to many hosts and patch it centrally. Which statement describes what a read-only software home changes for that plan?
選択肢
- The files that describe the local configuration are held inside the software directory but are marked as writable, so the directory can still be copied to another host without any change to those files.
- The files that describe the local configuration are removed after the installation, so each host rebuilds them from the parameter file of its own database when the instance is started.
- The files that describe the local configuration are copied into the recovery area, so the software directory can be replaced at any time and the configuration is read back from there.
- The files that describe the local configuration and the files that record the local activity are held outside the software directory, so the directory itself holds nothing that differs from one host to another.
