NEW QUESTION # 50
How do ASM failure groups provide redundancy?

• A. Extended Redundancy mirrors data across data centers providing the highest levels of data protection.
• B. Failure groups contain all ASM disks in a single storage server preventing mirror copies being written to the same storage server.
• C. Failure groups are created for each grid disk to ensure mirror copies are written to the same storage server for faster recovery after a physical disk failure.
• D. They ensure that the ASM Flex instances are enabled on a maximum of two database servers or VMs per cluster.

Answer: B

Explanation:
In an Automatic Storage Management (ASM) environment, failure groups are used to provide redundancy for the storage disks. Failure groups are used to group together a set of disks and ensure that no two copies of the same data are stored on the same physical disk or storage server. This way, if a disk or storage server fails, the data can still be accessed from the other copy.
For example, if the disks in a failure group are mirrored, one copy of the data is stored on one set of disks, and the other copy is stored on another set of disks. This way, if a disk or storage server fails, the data can still be accessed from the other copy.
ASM failure groups also provide the option to spread the data across different storage servers, this way, even if a storage server fails, data can still be accessed from the other storage servers in the group. This will improve the availability of the data.
