- A) Storing binary and text data
- B) Running applications in VM
- C) Relational databases
- D) Real-time analytics
Answer: A) Storing binary and text data
Explanation: Azure Blob storage is optimized for storing large amounts of unstructured data, such as text or binary data.
True or False: Azure storage services are globally redundant by default.
- Answer: False
Explanation: Azure storage redundancy can be configured per the requirement. It might be locally redundant, globally redundant or zone redundant based on the requirement.
Interview Questions
What Azure storage services can be used to store unstructured data and provide highly available access to data from anywhere in the world?
Azure Blob Storage is designed to handle unstructured data and provides highly available access to data from anywhere.
How is Azure File Storage different from Azure Blob Storage?
Azure File Storage offers shared storage for applications using the standard SMB (Server Message Block). This is different from Blob Storage which is optimized for storing massive amounts of unstructured data.
Can Azure Queue Storage be used to store data for longer periods?
Yes, Azure Queue Storage can keep messages for up to seven days, making it suitable for storing data for longer periods.
Which Azure storage service provides a NoSQL database?
Azure Cosmos DB provides a NoSQL database service.
Can Azure Table Storage handle transactions across multiple tables?
No, Azure Table Storage supports transactions on a per-partition basis only.
Which Azure storage service would you use to improve the speed of access to commonly used data?
Azure Disk Storage is typically used to improve the speed of access to commonly used data.
What is the maximum size of a singe blob in Azure Blob Storage?
A single blob in Azure Blob Storage can be up to 4.77 TB in size.
Which Azure storage service is suitable for developing applications requiring scalable, durable, and highly available secure disk storage for Azure Virtual Machines?
Azure Disk Storage is designed to provide scalable, durable, and highly available secure disk storage for Azure Virtual Machines.
Can Azure Blob Storage handle both structured and unstructured data?
Azure Blob Storage is primarily designed for unstructured data, like images and logs, rather than structured data.
Is Azure Disk Storage designed for structured or unstructured data?
Azure Disk Storage is a block-level storage service and is generally used for structured data.
How does Azure File Storage facilitate data sharing?
Azure File Storage supports the Server Message Block (SMB) protocol which allows applications on multiple machines to share files and folders.
What is Azure Cosmos DB and what does it offer?
Azure Cosmos DB is a globally distributed, multi-model database service. It offers turnkey global distribution, transparent multi-master replication, and guarantees single-digit millisecond latency at the 99th percentile.
How long can Azure Storage Queue keep a message before it gets deleted?
Azure Storage Queue can keep a message for up to 7 days before it gets automatically deleted if not explicitly deleted by the application.
How does Azure Archive Storage differ from other Azure storage services?
Azure Archive Storage is a cost-effective solution for long term storage of data that is not accessed frequently and can tolerate several hours of retrieval latency.
What kind of data does Azure Table Storage typically handle?
Azure Table Storage typically handles structured NoSQL data, providing key-attribute store with a schemaless design.
