Question 1
The correct answer is C. To enable log file mirroring, you simply assign the fully qualified name of the mirror log location (path) to the mirrorlogpath database configuration parameter.
Question 2
The correct answer is B. When a transaction failure occurs, all work done by partially completed transactions that have not yet been externalized to the database is lost. The database might be left in an inconsistent state (and therefore will be unusable). Crash recovery is the process used to return such a database to a consistent and usable state. To perform crash recovery, you must use information stored in the transaction log files to complete any committed transactions that were in memory (but had not yet been externalized to storage) when the transaction failure occurred, roll back any incomplete transactions, and purge any uncommitted transactions from memory...
