On a routine monitoring of the data files and transaction log, you notice that the transaction log is extremely close to being full. What will happen if the log fills? What steps can you take to avoid running out of transaction log space?

If the transaction log fills, you are unable to modify the data in the database until the log is archived or expanded. To avoid a full transaction log, you can monitor the log space regularly, expand the log whenever necessary, set the log to grow automatically, and create an alert to notify you when the available log space falls below a specified level (alerts are not covered in this training kit). Scheduling or performing frequent transaction log dumps is the best way to reclaim available space in the transaction log.
