The answer is cloud federation, the correct choice because it specifically enables multi-provider redundancy by allowing different cloud providers to share authentication, data, and resources, so if the primary provider fails, another can seamlessly take over. This goes beyond general high availability, which often works within a single provider, and directly addresses the need for inter-provider failover. On the CompTIA A+ Core 2 220-1202 exam, this concept tests your understanding of how to architect resilient cloud backups; a common trap is confusing it with load balancing, which distributes traffic but doesn’t guarantee data access during a provider outage, or disaster recovery, which is a broader plan rather than a specific technology. Remember the memory tip: “Federation = Friends across providers,” meaning multiple clouds federate to back each other up, ensuring your data survives any single provider’s downtime.
220-1102 Virtualization and Cloud Technologies Practice Question
This 220-1202 practice question tests your understanding of virtualization and cloud technologies. 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 technician is configuring a cloud-based backup solution for a company's critical data. The company wants to ensure that if the primary cloud provider experiences an outage, the data remains accessible from another provider. Which concept should the technician implement?

Correct answer & explanation
✓
Cloud federation
Cloud federation allows different cloud providers to share resources and data, enabling failover and redundancy. This ensures data accessibility even if one provider goes down. High availability is a general concept, not specific to multi-provider redundancy. Load balancing distributes traffic but does not guarantee data access during a provider outage. Disaster recovery is a broader plan, but federation is the specific technology for inter-provider failover.
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.
✗
High availability
Why it's wrong here
High availability typically refers to redundancy within a single provider, not across different providers.
✓
Cloud federation
Why this is correct
Cloud federation enables interoperability between different cloud providers, allowing data to be replicated and accessed across them.
Clue confirmation
The clue word "primary" in the question point toward this answer.

✗
Load balancing
Why it's wrong here
Load balancing distributes workload across resources but does not provide data redundancy across providers.
✗
Disaster recovery plan
Why it's wrong here
A disaster recovery plan outlines procedures, but cloud federation is the technical implementation for multi-provider failover.
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.

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 220-1202 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.
