Final answer:
The number of log archive files maintained at one time depends on the system configuration and there is no standard number. It varies based on the database or log management system and the settings chosen by the administrator.
Step-by-step explanation:
The question regarding how many log archive files are maintained at any one time does not have a universal answer, as it depends on the specific configuration of the log management system or database management system being used. In the context of database systems like Oracle, the number of log archive files is determined by the configuration set by the database administrator (DBA). This figure can be set to any number based on how much redundancy and history the DBA wants to keep for purposes such as recovery, replication, and auditing.
For systems like Oracle, there is a parameter called LOG_ARCHIVE_MAX_PROCESSES which can be used to define the number of processes allocated to perform archival operations, but the number of archive logs maintained is governed by factors such as available disk space, retention policies, and backup schedules. Without context, options A) 3, B) 5, C) 7, D) 10 are arbitrary and cannot be accurately answered. It's important to consult system documentation or a database administrator for system-specific configurations.
SUMUP of the final answer:
- The number of log archive files maintained is determined by the system's configuration.
- There is no standard number applicable to all systems; it is customized based on specific needs and settings.
- Consult system-specific documentation or a DBA for the exact number.
