Explanation

This question tests knowledge of Azure Blob Storage immutability policies and access tiers to meet WORM (Write Once, Read Many) compliance requirements while minimizing costs.

Approach. For the storage account, you should recommend Azure Blob Storage with a time-based retention policy (immutability policy) set to 5 years - this enforces WORM compliance, preventing modifications and deletions until the retention period expires. For the access tier, you should select the Hot tier since the data is accessed daily (frequent access), which minimizes data access/retrieval charges compared to Cool or Archive tiers. The time-based retention policy in Azure Blob Storage (immutable storage) locks data so it cannot be modified or deleted during the retention interval, and after 5 years the data can be deleted but never modified, perfectly matching all stated requirements.

Concept tested. Azure Blob Storage immutable storage (WORM policies) with time-based retention policies, combined with appropriate access tier selection (Hot vs Cool vs Archive) to balance access frequency and cost optimization.
