- A
Block storage (EBS / Azure Disk)
Block storage provides low-latency, persistent storage for VMs.
- B
File storage (EFS / Azure Files)
Why wrong: File storage is shared and has higher latency, not ideal for databases.
- C
Archive storage
Why wrong: Archive storage is for cold data, not for active databases.
- D
Instance store
Instance store provides very low latency but is ephemeral; could be used if data can be replicated.
- E
Object storage
Why wrong: Object storage has higher latency and is not designed for database workloads.

CV0-004 Cloud Architecture and Design Practice Question
This CV0-004 practice question tests your understanding of cloud architecture and design. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A cloud architect is designing a solution for a financial analytics application that requires consistent, low-latency block storage for a database. The database will be deployed on a virtual machine in a public cloud. Which TWO storage types are appropriate for this requirement? (Select TWO.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Block storage (EBS / Azure Disk)
Block storage (e.g., Amazon EBS, Azure Disk) is designed for low-latency, consistent performance for databases running on VMs. Instance store provides temporary block-level storage physically attached to the host, offering very low latency but is ephemeral. Object storage is not suitable for databases due to latency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CV0-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
