Full backup: Contains all data in the database.
A full backup is the baseline backup that includes the entire database.
- B
Differential backup: Contains all changes since the last full backup.
A differential backup captures all data modifications since the last full backup.
- C
Transaction log backup: Contains all committed transactions since the last transaction log backup.
Transaction log backups record individual transactions for point-in-time recovery.
- D
Full backup: Contains only changes since the last full backup.
Why wrong: Incorrect — this describes a differential backup, not a full backup.
- E
Differential backup: Contains all committed transactions since the last full backup.
Why wrong: Incorrect — differential backups contain data changes, not individual transactions; that is the role of transaction log backups.

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.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the 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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
