The answer is object storage, as it is the cloud storage model designed for file-level backup with versioning, allowing you to recover individual files from any point in the last 30 days. Object storage stores data as discrete objects with unique identifiers and rich metadata, which makes it inherently suited for versioning—each change creates a new object version without overwriting the original, enabling precise point-in-time recovery. On the CompTIA A+ Core 1 220-1201 exam, this question tests your ability to distinguish storage models by use case: block storage is for raw volumes like virtual hard drives, file storage is for shared network folders, and object storage is the go-to for scalable, granular backup with versioning. A common trap is picking file storage because it sounds file-friendly, but file storage lacks native versioning and is designed for concurrent access, not historical recovery. Remember the mnemonic “Object Offers Old-file Options” to link object storage with versioning and point-in-time file recovery.
220-1201 Cloud Computing Concepts Practice Question
This 220-1201 practice question tests your understanding of cloud computing concepts. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 technician is configuring a cloud-based backup solution for a client's critical data. The client requires that data be stored in a way that allows quick recovery of individual files from any point in the last 30 days. Which cloud storage model is most appropriate?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Object storage
Object storage is ideal for storing and retrieving individual files with versioning capabilities, enabling point-in-time recovery. It is scalable and commonly used for backup. Block storage is for raw volumes, and file storage is for shared file systems, but object storage offers the best granularity for file-level recovery over time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Block storage
Why it's wrong here
Block storage provides raw storage volumes typically used for databases or VMs, not optimized for individual file versioning.
✗
File storage
Why it's wrong here
File storage uses a hierarchical file system, but versioning is not a native feature; it's more suited for shared access.
✓
Object storage
Why this is correct
Object storage stores data as objects with metadata and supports versioning, allowing recovery of previous file versions.

✗
Cold storage
Why it's wrong here
Cold storage is for long-term archival with infrequent access, not for quick recovery of individual files within 30 days.
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 220-1201 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.
