CompTIA Cloud Essentials+ (CLO-002)Management and Technical OperationsHard
A cloud architect is designing a new application that will process sensitive customer data. The application requires highly available and scalable storage that can be accessed by multiple compute instances simultaneously. Data encryption at rest and in transit is a strict requirement. Which storage type is BEST suited for this scenario?
- ABlock Storage
- BEphemeral Storage
- CObject Storage
- DArchive Storage
Show answer & explanationAnswer & explanation
Correct answer: C. Object Storage
Object storage is highly scalable, highly available by design, inherently supports encryption at rest and in transit, and can be accessed concurrently by multiple compute instances via APIs, making it ideal for sensitive, shared, and scalable data processing.
Why the other options are wrong
- A. Block storage is typically attached to a single compute instance (like a hard drive) and is not inherently designed for concurrent access by multiple instances or high scalability for application data.
- B. Ephemeral storage is temporary and tied to a compute instance's lifetime, unsuitable for persistent sensitive data.
- D. Archive storage is for long-term, infrequent access, not for active processing by an application due to high retrieval latency.
Object Storage
A cloud storage architecture that manages data as objects, offering high scalability, availability, durability, and features like metadata tagging and encryption, accessible via APIs.
- Highly scalable (virtually unlimited).
- High availability and durability.
- Supports encryption at rest and in transit.
- Accessed via API, enabling concurrent access by multiple services.
