AZ-104: Microsoft Azure Administrator Full Course - Zone Redundant Storage

The video tutorial explains Zone Redundant Storage (ZRS), which synchronously replicates data across three storage clusters in a single region, ensuring data availability even if a zone becomes unavailable. ZRS is not available in all regions and transitioning to it requires physical data movement. It provides excellent performance but may not protect against regional disasters, for which Geo Redundant Storage is recommended. ZRS supports various data types and maintains data accessibility during zone outages, with best practices for transient fault handling advised.

What is a key feature of Zone Redundant Storage (ZRS)?

• It replicates data across multiple regions.

• It only supports disk page blobs.

• It synchronously replicates data across three storage clusters in a single region.

• It provides protection against regional disasters.

Which of the following is true about changing to ZRS from another data replication option?

• It requires physical data movement from a single storage stamp to multiple stamps within a region.

• It automatically protects against regional disasters.

• It requires no physical data movement.

• It is available in all regions.

What does ZRS offer in case of temporary unavailability?

• Complete data loss

• Resiliency for your data

• Increased data latency

• Automatic data backup

What is recommended for protection against regional disasters?

• Local Redundant Storage

• Zone Redundant Storage

• Geo Redundant Storage

• Read-Access Geo Redundant Storage

What should be implemented to handle transient faults when a zone is unavailable?

• Increased data storage

• Manual data replication

• Immediate data deletion

• Retry policies with exponential backoff
