The video tutorial explains Locally Redundant Storage (LRS) as a cost-effective option for data protection against local hardware failures. It details the architecture of LRS, which involves replicating data within a single data center to ensure durability. However, LRS is limited in scenarios of data center-level disasters like fires or floods, where other storage options like zone redundant or geo redundant storage are recommended. The tutorial also highlights the importance of data governance requirements and when LRS is suitable.

What is a key reason to choose LRS for data storage?

• It replicates data across multiple regions for maximum safety.

• It offers the highest durability among all storage options.

• It is the best choice for applications requiring global data access.

• It is the most cost-effective option for data that can be easily reconstructed.

How does LRS ensure data durability within a data center?

• By using a single copy of data in a secure vault.

• By encrypting data with advanced algorithms.

• By maintaining three copies of data within a single facility.

• By replicating data across multiple data centers.

What is a fault domain in the context of LRS?

• A collection of racks of storage nodes.

• A single node responsible for data replication.

• A group of nodes that represent a physical unit of failure.

• A group of nodes that are upgraded together.

Why might LRS not be suitable in the event of a data center-level disaster?

• It does not support data encryption.

• It is too expensive for most organizations.

• It requires manual intervention for data recovery.

• It only replicates data within a single data center.

Which storage option should be considered for protection against data center-level disasters?

• Single Node Storage (SNS)

• Zone Redundant Storage (ZRS)

• Local Redundant Storage (LRS)

• Encrypted Redundant Storage (ERS)
