AZ-305 Design data storage solutions Practice Question
A company wants to store log data from multiple applications for up to 30 days for analysis. The data is append-only, and queries are infrequent but need to be fast when run. Which Azure data storage solution should you recommend?
⚠ Common exam trap
A common mix-up: candidates choose Azure Blob Storage (archive tier) for cost savings, overlooking the explicit requirement for fast query performance, which the archive tier cannot provide due to its multi-hour rehydration latency.

Correct answer & explanation
✓
Azure Log Analytics Workspace
Azure Log Analytics Workspace is the correct choice because it is purpose-built for ingesting, storing, and querying log data from multiple sources. It supports append-only log ingestion, retains data for up to 30 days in its interactive retention tier (configurable), and provides fast Kusto Query Language (KQL) queries for infrequent analysis. The workspace integrates natively with Azure Monitor and other services, making it ideal for centralized log analysis.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Log Analytics Workspace
Why this is correct
Log Analytics is built for log data, fast queries, and configurable retention.
- ✗
Azure Table Storage
Why it's wrong here
Table Storage is for NoSQL structured data, not ideal for log analysis.
- ✗
Azure Data Lake Storage Gen2
Why it's wrong here
Data Lake is for big data analytics with high throughput, but more expensive for simple log storage.
- ✗
Azure Blob Storage (archive tier)
Why it's wrong here
Archive tier is for long-term cold storage; querying is slow and not cost-effective for 30 days.
