Zorluk: OrtaData Integration and Analytical Storage

An educational technology company is designing a data integration and analytics platform to process student learning platform telemetry. The platform must meet the following requirements:
- Store and analyze 12 TB of historical student activity logs currently formatted as Parquet files.
- Ingest new telemetry logs as Parquet files at a rate of 15 GB per hour.
- Support ad-hoc exploratory queries using standard T-SQL with a target latency of under 10 seconds.
- Maintain data availability even in the event of a primary Azure region failure.
- Minimize administrative and compute costs associated with the ad-hoc queries.
- Provide secure access to external research partners that can be easily revoked.

Which two actions should you recommend?

  1. Configure the Azure Data Lake Storage Gen2 account to use Geo-Redundant Storage (GRS).Cevap
  2. Use Azure Synapse Analytics serverless SQL pools to execute T-SQL queries directly on the Parquet files.Cevap
  3. C
    Provision an Azure Synapse dedicated SQL pool to import and query the Parquet files.
  4. D
    Configure the Azure Data Lake Storage Gen2 account to use Locally Redundant Storage (LRS).
  5. E
    Create a Shared Access Signature (SAS) token with a five-year expiration time to provide direct access for external analysts.

Cevap

Configure the Azure Data Lake Storage Gen2 account to use Geo-Redundant Storage (GRS) and use Azure Synapse Analytics serverless SQL pools to execute T-SQL queries directly on the Parquet files.
Configuring the Azure Data Lake Storage Gen2 account to use Geo-Redundant Storage (GRS) satisfies the requirement to survive a regional outage, and using serverless SQL pools enables querying the data directly in the lake using T-SQL while minimizing compute costs and administrative overhead.

Adım Adım Çözüm

1
Analyze storage redundancy requirements.
Identify that Geo-Redundant Storage (GRS) is required to survive a primary region outage.
Locally Redundant Storage (LRS) is insufficient for regional disaster resilience.
2
Evaluate query models for cost-efficient ad-hoc exploration.
Choose Azure Synapse Analytics serverless SQL pools over dedicated SQL pools.
Serverless SQL pools query files in place, avoiding the cost and overhead of provisioning dedicated clusters.

Anahtar Kavram

Selecting appropriate analytical query services and storage redundancy models based on cost, performance, and availability constraints.
