Exam AZ-305 topic 4 question 43 discussion

appeared in exam, 10/14/2022. I passed with 946/1000 and there were only 1~2 new questions but others were all from AZ-305 dump.

The correct answer is D. Azure Cosmos DB. Azure Cosmos DB is a globally distributed, multi-model database service. It provides comprehensive service level agreements (SLAs) covering throughput, latency, availability, and consistency. The other options do not provide an SLA for both latency and throughput.

D is correct

The Given answer D is correct Tip: Whenever you see those words "mission critical application/Data" you can be sure 9/10 it is Azure Cosmo DB if it is part of solution proposed. Key Benefits of Azure Cosmos DB The guaranteed speed at any scale: Fast read and write latencies worldwide. Multi-region writes (Multi Master Writes)and ease of data distribution to any Azure region. Scale storage and throughput across any Azure region independently and elastically. Mission-critical ready: Azure Cosmos DB is backed by an extensive suite of SLAs, including industry-leading availability worldwide. The automatic data replication feature helps to distribute data across any Azure region efficiently. Data safety is ensured by Azure role-based access control.

Should not it be worded as "Database Solution" instead of "Storage solution" for the records of a mission critical application ? "Storage Solution" misleads one to think about storage tiers.

D is the answer. https://learn.microsoft.com/en-us/azure/cosmos-db/introduction#guaranteed-speed-at-any-scale Gain unparalleled SLA-backed speed and throughput, fast global access, and instant elasticity. - Real-time access with fast read and write latencies globally, and throughput and consistency all backed by SLAs - Multi-region writes and data distribution to any Azure region with just a button. - Independently and elastically scale storage and throughput across any Azure region – even during unpredictable traffic bursts – for unlimited scale worldwide.

zure Cosmos DB provides a comprehensive SLA for write latency and throughput. Additionally, it is a highly scalable and globally distributed database designed for mission critical applications. It provides low-latency, highly available, and scalable access to data. Cosmos DB also supports multiple data models, including document, key-value, graph, and column-family data models, which can be used to store structured and unstructured data.

D. Azure Cosmos DB

D is correct

D is correct. Cosmos includes the SLA guarantees.

The SLA terms are the only thing that make it Cosmos over SQL.
