CompTIA Cloud+ (CV0-004)Cloud ArchitectureEasy
A cloud administrator is configuring a database that requires consistent, low-latency access to data with high IOPS (Input/Output Operations Per Second). The database will be actively used by a critical production application. Which storage tier is most appropriate for this workload?
- AStandard Block Storage
- BFile Storage (NFS)
- CArchive Storage
- DCold Object Storage
Show answer & explanationAnswer & explanation
Correct answer: A. Standard Block Storage
Standard Block Storage is designed for persistent, high-performance storage volumes that offer consistent, low-latency access and high IOPS, making it ideal for active databases and critical production applications.
Why the other options are wrong
- B. File Storage (NFS) is for shared file systems, not typically optimized for the high IOPS and low latency requirements of a critical database.
- C. Archive Storage is for long-term retention with very high latency, unsuitable for active databases.
- D. Cold Object Storage is for infrequent access and high latency, unsuitable for active databases.
Standard Block Storage
A type of storage that provides raw, unformatted volumes that can be attached to instances, offering high performance, low latency, and consistent IOPS for critical applications.
- Ideal for databases, boot volumes, and high-performance workloads.
- Offers persistent storage independent of the compute instance.
- Can be provisioned with specific IOPS and throughput characteristics.
Memory trick: For 'critical database' with 'high IOPS', 'Standard Block Storage' is the 'Best'.
