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
✓
Cloud-based DR with pay-as-you-go.
Option D is correct because a cloud-based DR site with pay-as-you-go model requires no upfront investment in hardware and can be spun up as needed, making it cost-effective for a business with a high downtime tolerance. Option A is wrong because a hot site is the most expensive, with real-time replication. Option B is wrong because a warm site requires pre-installed hardware that incurs ongoing costs, even if data is not up-to-date. Option C is wrong because a cold site still requires occasional maintenance and may have hidden costs; modern cloud DR can be cheaper and more flexible.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Cloud-based DR with pay-as-you-go.
Why this is correct
Cloud DR allows the business to pay only when resources are consumed, eliminating upfront investment and ongoing idle hardware costs, ideal for a limited budget and relaxed RTO.
- ✗
Cold site with no pre-configured hardware.
Why it's wrong here
While traditionally considered cheap, a cold site still requires physical space and equipment procurement during a disaster; cloud DR can be more cost-effective with less management overhead.
- ✗
Hot site with real-time replication.
Why it's wrong here
A hot site maintains fully mirroring infrastructure, making it the most expensive option and unsuitable for a limited budget with high downtime tolerance.
- ✗
Warm site with pre-installed hardware but no data.
Why it's wrong here
A warm site requires hardware that is installed and partially configured, incurring moderate ongoing costs without the benefit of immediate failover.
