When looking at an organization's file server configuration, an IT manager determines that several outages are tied to a lack of redundancy in the disk controller configuration.

A. B. C. D. E.E.
The IT manager would look for a feature that provides redundancy in the disk controller configuration. This means that if one disk controller fails, the system can continue to function with minimal disruption.
Out of the given options, the feature that provides redundancy in the disk controller configuration is Disk duplexing, also known as disk mirroring.
Disk duplexing is a type of RAID 1 configuration that involves duplicating the data on two separate disks. Each disk has its own disk controller, providing redundancy in case one of the controllers fails. If one disk fails, the other disk can take over without any interruption to the system.
Disk shadowing is a term used to describe a type of backup method that creates a duplicate copy of data on a secondary disk. It does not provide redundancy in the disk controller configuration.
RAID 0 is a type of disk configuration that stripes data across multiple disks. It does not provide redundancy, and if one disk fails, the entire system can be impacted.
Remote journaling is a feature that logs changes to a file system on a remote server. It is used for disaster recovery purposes, but it does not provide redundancy in the disk controller configuration.
Electronic vaulting is a backup process that involves backing up data to a remote location. It does not provide redundancy in the disk controller configuration.
In conclusion, the IT manager should look for disk duplexing as the feature that provides redundancy in the disk controller configuration to correct the outages.
