AZ-802 Manage Storage and File Services Practice Question
Exhibit
PS C:\> Get-StoragePool -FriendlyName "S2D*" | Get-ResiliencySetting Name NumberOfDataCopies PhysicalDiskRedundancy MinPoolSize ---- ------------------ ---------------------- ----------- Mirror 3 2 3
Refer to the exhibit. A Storage Spaces Direct cluster is configured with the resiliency settings shown. What is the maximum number of simultaneous drive failures this pool can sustain without losing data access?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Two drive failures
The exhibit shows a three-way mirror configuration, indicated by NumberOfDataCopies being set to three. In Storage Spaces Direct, a three-way mirror can tolerate the simultaneous failure of two disks or two entire nodes. This high level of redundancy is standard for mission-critical workloads requiring maximum uptime and data integrity.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
One drive failure
Why it's wrong here
A single drive failure is typical for two-way mirroring or parity configurations. Since this pool is configured with three data copies and a physical disk redundancy of two, it is designed to survive more than just one failure without losing data or impacting volume availability for users.
- ✓
Two drive failures
Why this is correct
In a three-way mirror, the system maintains three distinct copies of every data block on different physical disks. This configuration specifically allows the cluster to sustain the loss of two physical disks simultaneously while still maintaining a complete, accessible copy of the data on the remaining drive.
- ✗
Three drive failures
Why it's wrong here
While there are three copies of the data, losing three drives simultaneously would mean all copies of certain data blocks are lost, resulting in volume failure. The system redundancy level is explicitly set to two, meaning it cannot survive a third concurrent failure without data loss occurring.
- ✗
Zero drive failures
Why it's wrong here
A value of zero would imply no redundancy, such as a simple stripe set where any single failure causes total data loss. The exhibit clearly indicates that the pool has been configured with resiliency settings that allow for multiple failures while maintaining operational status and data integrity.
