CISA Practice Question: Which TWO of the following are essential controls…
Which TWO of the following are essential controls to ensure data integrity during a cloud migration project?
⚠ Common exam trap
A common mix-up: candidates confuse encryption with confidentiality and overlook its role in integrity, or they assume that a single post-migration validation (Option E) is sufficient, ignoring the need for ongoing reconciliation checks (Option D) to detect incremental data loss or corruption during the transfer process.
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
✓
Implementing encryption at rest and in transit
Encryption at rest and in transit (Option B) is essential for maintaining data integrity during cloud migration because it prevents unauthorized modification or corruption of data while stored in the source or target systems and while being transferred over networks. Without encryption, data is vulnerable to tampering, which directly undermines integrity. This control aligns with the principle of protecting data throughout its lifecycle, a key requirement in cloud migration projects.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Granting all migration team members full database access
Why it's wrong here
This violates the principle of least privilege and increases risk of unauthorized changes.
- ✓
Implementing encryption at rest and in transit
Why this is correct
Encryption ensures data confidentiality and integrity during transfer and storage.
- ✗
Using a phased migration approach without rollback capability
Why it's wrong here
Without rollback, any failure could result in significant data loss or downtime.
- ✓
Running reconciliation checks comparing source and target data counts
Why this is correct
Reconciliation verifies completeness and accuracy of the migration.
- ✗
Performing a single full data validation after migration
Why it's wrong here
Validation should be continuous and iterative, not a single event.
