第4题:
Sometimes performance is more important than availability (e.g., in cases where the data can be easily re-created). Which of the following is the appropriate disk configuration for an application that requires faster writes over availability?()
第5题:
Full Atomicity, Consistency, Isolation, Durability (ACID) compliance is a necessity for a new application, which heavily reads and writes data. This requires the following config file options: Sync_binlog=1 Innodb_flush_log_at_trx_commit=1 Innodb_doublewrite=1 However, this configuration is expected to introduce disk I/O overhead. What three changes will reduce disk I/O overheads?()

Disk fragmentation
Performance results analysis
Capacity forecasting and planning
Resource contention and availability
第7题:
Use of soft links for database directories on the same physical disk
Use of delay_key_write=ON for batch index update
Allocation of RAM to the buffer pool such that more of the data can fit in RAM
Placement of InnoDB log files and datadir on separate physical disks
Use of separate directories on the same physical disk for log files and data files
