A. B. C. D.B.
Electronic vaulting refers to the transfer of backup data to an off-site location.
This is primarily a batch process of dumping backup data through communications lines to a server at an alternate location.
Electronic vaulting is accomplished by backing up system data over a network.
The backup location is usually at a separate geographical location known as the vault site.
Vaulting can be used as a mirror or a backup mechanism using the standard incremental or differential backup cycle.
Changes to the host system are sent to the vault server in real-time when the backup method is implemented as a mirror.
If vaulting updates are recorded in real-time, then it will be necessary to perform regular backups at the off-site location to provide recovery services due to inadvertent or malicious alterations to user or system data.
The following are incorrect answers: Remote journaling refers to the parallel processing of transactions to an alternate site (as opposed to a batch dump process).Journaling is a technique used by database management systems to provide redundancy for their transactions.
When a transaction is completed, the database management system duplicates the journal entry at a remote location.
The journal provides sufficient detail for the transaction to be replayed on the remote system.
This provides for database recovery in the event that the database becomes corrupted or unavailable.
Database shadowing uses the live processing of remote journaling, but creates even more redundancy by duplicating the database sets to multiple servers.
There are also additional redundancy options available within application and database software platforms.
For example, database shadowing may be used where a database management system updates records in multiple locations.
This technique updates an entire copy of the database at a remote location.
Data clustering refers to the classification of data into groups (clusters).Clustering may also be used, although it should not be confused with redundancy.
In clustering, two or more "partners" are joined into the cluster and may all provide service at the same time.
For example, in an active-active pair, both systems may provide services at any time.
In the case of a failure, the remaining partners may continue to provide service but at a decreased capacity.

The answer to the question is B. Electronic vaulting.
Electronic vaulting is a batch process that transfers backup data to an alternate location using communication lines. It involves copying data to a remote server or offsite storage facility to protect it against data loss, theft, or disaster. The backup data is typically compressed and encrypted to ensure its security during transmission.
Remote journaling, on the other hand, is a process of keeping a copy of data changes in a log file on a remote system. This is used to provide a record of transactions that can be used to recover data in case of failure.
Data clustering is the process of grouping related data together to improve performance and reliability. It is typically used in database management systems to increase availability and scalability.
Database shadowing involves maintaining a copy of the primary database on a secondary system. This is used to ensure continuous availability of the database in case of failure. The secondary system is kept in sync with the primary system using techniques such as log shipping or replication.
In summary, electronic vaulting is the correct answer because it refers to the process of transferring backup data to an alternate location using communication lines.
