Explanation

This question tests knowledge of Azure Storage account types and blob storage tiers/features, specifically which combination maximizes throughput, minimizes latency, and enforces immutability for one year.

Approach. The correct storage account type is Premium Block Blob Storage (also known as BlockBlobStorage), which uses SSD-based storage to maximize throughput and minimize latency for read/write operations on large amounts of frequently accessed data. The correct storage service is Azure Blob Storage with an Immutability Policy (Time-based retention policy) set to one year - specifically using WORM (Write Once, Read Many) policies available in Blob Storage. Premium performance accounts provide single-digit millisecond latency and high transaction rates, making them ideal for frequently accessed large datasets. The immutability/time-based retention policy prevents modification or deletion of blobs for the defined retention period (one year), satisfying the compliance-like requirement.

Concept tested. Azure Storage account performance tiers (Standard vs. Premium), storage service types (Blob, File, Queue, Table), and blob immutability policies (WORM/time-based retention) for data protection and compliance.
