The answer is the hybrid cloud model. This is the correct choice because a hybrid cloud combines on-premises infrastructure with public cloud services, enabling a company to migrate its on-premises email server to a cloud service while retaining all existing emails and folders. During the transition, data can be synchronized between the local environment and the cloud, ensuring no emails are lost and employees maintain access throughout the process. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of deployment models in real-world migrations; a common trap is choosing public cloud, which would require a full cutover and risk data loss, or private cloud, which lacks the scalability for seamless migration. Remember the memory tip: “Hybrid holds the history”—it keeps your existing data local while bridging to the cloud.
220-1201 Cloud Computing Concepts Practice Question
This 220-1201 practice question tests your understanding of cloud computing concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 company is migrating its on-premises email server to a cloud service. Employees must retain all existing emails and folders. Which cloud deployment model best fits this requirement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Why wrong: Public cloud alone would require moving all data to the provider's servers, which may not allow retaining local copies during migration.
B
Private cloud
Why wrong: Private cloud is dedicated to one organization but still requires migration from on-premises; it doesn't inherently support a hybrid transition.
C
Hybrid cloud
Hybrid cloud allows the company to keep some data on-premises while moving other data to the cloud, enabling a smooth migration with full data retention.
D
Community cloud
Why wrong: Community cloud is shared by several organizations with common concerns, not designed for individual migration scenarios.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Hybrid cloud
A hybrid cloud deployment combines on-premises infrastructure with public cloud services, allowing data migration while maintaining local access during the transition. This ensures existing emails can be retained and synchronized. A public-only or private-only model would not support the migration seamlessly.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
