Fault tolerance is the ability of a system to continue working even when a fault exists. In the case of RAID, which stands for Redundant Array of Inexpensive Discs, fault tolerance is provided by having data recorded on more than one drive, and also by having more than one power supply. Note that RAID 0 is not fault telerant because it is simply stripes the data to increase size and bandwidth, but provides no redundancy. RAID 1 and RAID 5 are fault tolerant, to various levels.

What types of disk arrays provide the MOST fault tolerance?
RAID 6 provides the most fault tolerance of any standard RAID disk arrays (RAID 0, 1 , 5, 6, and RAID 10). If any two disks in a RAID 6 array fail and are removed, then two new blank disks can be installed and no data has been lost. RAID 1+1 or most other "layered" RAID systems can provide more fault tolerance than RAID 6, tolerating the failure of any 3 disks. Some experimental non-standard disk arrays can provide more fault tolerance with less overhead, such as the parchive system. Nearly all distributed file systems and distributed version control systems can be set up so that if one machine is completely destroyed by fire, all the data can be recovered from a backup machine in another building.
Which topology has the most fault tolerance and redundancy?
The star bus topology has the most fault tolerance.
To provide fault tolerance active directory utilizes what replication model?
RODC (Read-Only Domain Controller)
What are three benefits of a hierarchical network model?
simplification of management and troubleshootingelimination of the need for wiring closetsincreased fault tolerance of the networkMore scalable it allows you to replicate the the design elements as the networks grows.
Which method is most frequently used for providing fault tolerance to DHCP servers?
A) failover clusteringB) standby serversC) splitting scopes
Does RAID 0 provide fault tolerance?
RAID 0 does not provide any fault tolerance.
Which version of raid is supported by windows xp does this raid version provide fault tolerance?
Windows XP supports spanned and striped RAID 0 volumes Hardware RAID is considered a better solution for fault tolerance than software RAID RAID 0 does not provide fault tolerance
What raid level provides fault tolerance?
RAID 1 OR RAID 5 provide added performance as well as fault tolerance --- GAURAV TOMAR
Which type of RAID does not provide fault tolerance?
A: raid 0raid 0 is no fault tolerance...coz it writes the data parallely and it doesnot contain any mirror in that.
What hardware is needed to implement hardware RAID for fault tolerance?
raid card
What can be used to provide fault-tolerance to a system?
RAID storage can be used to provide fault-tolerance to a system. With RAID, data is stored redundantly on a set of disks to mitigate against failure of a disk.
Doe RAID 1 provides a high level of fault tolerance?
false
The drive conigurations supported by windows xp professional provides fault tolerance?
RAID 1, RAID 0+1, RAID 5 and 6.
Why doesn't RAID 0 provide fault tolerance?
RAID 0 does not provide fault tolerance, it's to use space form two or more physical disks and increases the disk space available for a single volume. (pg 406)
What deficiency is associated with RAID 0 compared with RAID 1?
RAID 0 is "Stripping" and RAID1 is "Mirroring". RAID0 doesn't provide fault tolerance but RAID1 does provide fault tolerance because it has a every disk has a mirrored disk so that in case of disk failure the other disk can be used.
What is RAID technology in server?
RAID technology uses multiple disk drives to achieve either fault tolerance or an increase in read and write performance.
What uses data striping to distribute data across multiple disks with no fault tolerance?
RAID 0
