CV0-004 Practice Question: Migrating its on-premises data center to the cloud
A company is migrating its on-premises data center to the cloud. The current backup solution uses a tape library. The company wants to implement a cloud-based backup strategy that ensures data durability and rapid restoration. Which of the following is the BEST option?
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
✓
Use cloud storage with versioning and lifecycle policies.
Cloud storage with versioning and lifecycle policies provides high data durability through redundancy across multiple geographic locations and enables rapid restoration by allowing recovery of previous versions of data. Option A is wrong because virtual tape libraries (VTL) are designed to emulate tape backups and may have slower restore times compared to object storage. Option C is wrong because block storage snapshots are typically used for cloud instances and are less suited for migrating large on-premises datasets. Option D is wrong because third-party backup software adds complexity and does not inherently provide the same durability and rapid restore capabilities as native cloud storage features.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use cloud virtual tape library (VTL).
Why it's wrong here
VTL mimics tape and may have slower restore times compared to direct object storage.
- ✓
Use cloud storage with versioning and lifecycle policies.
Why this is correct
Versioning protects against accidental deletion/corruption and allows immediate restore; lifecycle policies automate tiering for cost.
- ✗
Use block storage snapshots.
Why it's wrong here
Block storage snapshots are for cloud instances, not for backing up on-premises data directly.
- ✗
Use a third-party backup software that backs up to cloud storage.
Why it's wrong here
Third-party tools can be effective but depend on software configuration; not inherently rapid or durable.
