Design Data Storage Solutions Flashcards
Microsoft Azure Solutions Architect Expert AZ-305 Flashcards
| Front | Back |
| Define data lifecycle management in Azure | Automating data movement between storage tiers based on usage patterns or policies |
| Define scalability in data storage | The ability to handle increasing amounts of data and traffic efficiently |
| Explain the concept of Event Grid integration with Blob Storage | Enables event-driven architectures by firing events when changes occur in Blob Storage |
| How are access tiers in Blob Storage chosen programmatically | By configuring policies based on usage patterns or accessing frequency |
| How can Cosmos DB ensure global availability | By replicating data across multiple regions |
| How can you optimize costs in Azure storage solutions | By selecting appropriate storage tiers and cleaning up unused resources |
| How do redundancy options like LRS and GRS differ | LRS stores data in one data center; GRS replicates data to another region |
| How does Azure Archive Storage differ from cold storage | Archive storage is for rarely accessed data with higher latency, while cold storage is for infrequently accessed data with lower latency |
| How does Azure Backup integrate with Blob Storage | Azure Backup uses Blob Storage to securely store recovery points for resources |
| How does Azure provide data security | Through encryption at rest and in transit, and access controls |
| How does Azure Storage SLA ensure reliability | Guarantees uptime and data availability based on specific service tiers |
| What are Managed Disks in Azure | Highly durable and scalable disk storage for virtual machines |
| What does redundancy ensure in storage solutions | Availability and reliability by duplicating data across systems |
| What is Azure Blob Storage Data Lake used for | Storing and analyzing large-scale datasets for big data solutions |
| What is Azure Blob Storage used for | Storing unstructured data such as images and documents |
| What is Azure File Storage used for | Providing fully managed file shares accessible via SMB protocol |
| What is Cosmos DB in Azure | A globally distributed multi-model database service |
| What is Data Encryption Key (DEK) in Azure | A per-blob key used to encrypt individual objects in Blob Storage |
| What is geo-replication in Azure SQL Database | Replicating data across multiple geographic locations for redundancy and availability |
| What is premium storage tier used for | High-performance workloads requiring low latency and high throughput |
| What is the advantage of using Azure Files for SMB support | Enables on-premises applications to share files seamlessly with Azure-based services |
| What is the Azure Import/Export service | A physical data transfer solution to move large amounts of data to or from Azure using hard drives |
| What is the benefit of using Managed Service for Azure Storage | Reduces management overhead with automated updates and built-in high availability |
| What is the difference between hot and cold Blob storage tiers | Hot tier is for frequently accessed data; cold tier is for infrequently accessed data |
| What is the difference between read-access GRS and GRS | Read-access GRS allows read-only access to the secondary region, while GRS does not |
| What is the key benefit of Cosmos DB's multi-model support | Allows developers to use different data models such as document, key-value, and graph in a single database service |
| What is the primary use case for Azure Table Storage | Storing structured data in key-value pairs |
| What is the purpose of a shared access signature (SAS) | Provides secure delegated access to storage resources for specific time frames |
| What is the purpose of Azure Queue Storage | To store and deliver messages between application components asynchronously |
| What is the purpose of Azure Storage Explorer | A tool to manage and access Azure storage data like blobs, files, and tables |
| What is the purpose of lifecycle management in storage | Automatically moving data to lower-cost tiers to optimize costs over time |
| What is Zone Redundant Storage (ZRS) | A redundancy option that replicates data across three availability zones within a region |
| What type of data is best suited for Blob storage | Large files, streaming media, backups, and log files |
| When is Azure Disk Storage ideal | For high IOPS workloads such as databases and transactional applications |
| When should you use Azure Data Box | For transferring massive data to Azure when using the network isn’t feasible |
| When should you use SQL Databases in Azure | When structured and relational data storage is required |
| When would you use Azure SQL Managed Instance | For fully managed SQL Server in the cloud with built-in high availability |
| Why is data partitioning important in Cosmos DB | Improves performance by distributing data across partitions |
| Why use Cosmos DB over SQL Server for high scalability needs | Cosmos DB offers horizontal scaling and global distribution |
This deck covers Azure storage options like Blob storage, SQL databases, Cosmos DB, and ensuring storage solutions align with business needs such as scalability and redundancy.
