FC0-U71 Data and Database Fundamentals Practice Question
A cloud database service is being considered for a startup to avoid hardware maintenance and allow automatic scaling. Which type of service is this?
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
✓
Database as a Service (DBaaS)
Database-as-a-Service (DBaaS) provides managed database instances in the cloud, handling maintenance, backups, and scaling.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Software as a Service (SaaS)
Why it's wrong here
SaaS provides applications, not databases.
- ✓
Database as a Service (DBaaS)
Why this is correct
Correct. DBaaS offers managed database services with automatic scaling.
- ✗
Infrastructure as a Service (IaaS)
Why it's wrong here
IaaS provides virtual machines, but the customer manages the database software.
- ✗
Platform as a Service (PaaS)
Why it's wrong here
PaaS provides a runtime environment and middleware for deploying custom applications, but the startup’s requirement is specifically to avoid hardware maintenance and gain automatic scaling of the *database* itself. That need is met by Database as a Service (DBaaS), which abstracts the database engine and storage layer. PaaS is tempting because it also abstracts infrastructure, but it would still require the startup to manage the database software and scaling logic manually. PaaS would be correct if the startup needed to deploy a custom web application without managing the underlying OS and runtime.

Same concept, more angles
3 more ways this is tested on FC0-U71
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which of the following are advantages of using a cloud database service (DBaaS) compared to an on-premises database? (Select TWO.)
easy- A.Full control over underlying hardware
- B.Requires dedicated IT staff for database administration
- ✓ C.Managed maintenance and updates
- D.Higher initial capital expenditure
- ✓ E.Automatic scalability
Why C: DBaaS provides managed maintenance and automatic scalability without hardware management. High availability is inherent, and initial cost is lower (pay-as-you-go).
Variation 2. Which TWO of the following are benefits of using a cloud database service (DBaaS) over an on-premises database?
medium- ✓ A.No need to manage physical hardware
- B.Full control over the operating system
- C.Lower latency guaranteed
- D.Data is always stored locally
- ✓ E.Automatic scaling of resources
Why A: DBaaS eliminates the need for hardware management and allows easy scaling of resources on demand.
Variation 3. Which THREE of the following are advantages of using a cloud database service (DBaaS) over an on-premises database? (Select THREE.)
hard- ✓ A.No need to manage physical hardware
- ✓ B.Built-in backup and disaster recovery options
- C.Lower latency than on-premises in all cases
- ✓ D.Automatic scaling based on demand
- E.Full control over the operating system
Why A: DBaaS provides managed services, automatic scaling, and no hardware management, reducing operational overhead.
