FC0-U71 Data and Database Fundamentals Practice Question
Which THREE of the following are advantages of using a cloud database service (DBaaS) over an on-premises database? (Select THREE.)
⚠ Common exam trap
FC0-U71 often tests the misconception that cloud databases always have lower latency than on-premises, when in fact latency depends on network topology and can be higher for remote cloud regions.

Correct answer & explanation
✓
No need to manage physical hardware
Option A is correct because a DBaaS provider owns and operates the underlying physical servers, storage, and networking, so the customer is freed from hardware procurement, racking, cabling, and maintenance tasks. Option B is correct because DBaaS platforms typically include managed automated backups, point-in-time recovery, and cross-region replication or failover as built-in features, reducing the administrative burden of designing and testing a DR strategy. Option D is correct because DBaaS offerings commonly provide elastic scaling of compute, storage, and IOPS—often automatically or via simple configuration changes—to match changing workload demand without manual capacity planning. Option C is not correct because latency depends on network distance and topology; a cloud database can be slower than a local on-premises database when the application and data are geographically separated. Option E is not correct because DBaaS abstracts the operating system away from the customer, who generally has little or no OS-level access, unlike on-premises deployments where full OS control is retained.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
No need to manage physical hardware
Why this is correct
DBaaS shifts physical host provisioning, patching and capacity to the provider, so the customer never racks, cables or replaces server hardware. This directly satisfies the stem's advantage criterion by removing hardware lifecycle management from the organisation's operational scope.
- ✓
Built-in backup and disaster recovery options
Why this is correct
Built-in backup and disaster recovery options satisfy the resilience requirement without on-premises infrastructure. The provider automates snapshots, point-in-time restore and geo-replication across regions, removing the need to procure secondary hardware, replicate storage manually or maintain standby servers. This directly addresses the stem's advantage of reduced operational overhead compared with self-managed on-premises databases.
- ✗
Lower latency than on-premises in all cases
Why it's wrong here
Latency depends on network distance between client and database region, so a cloud database can be slower than a co-located on-premises server. It is tempting because cloud providers offer many regions and edge locations, which reduce latency only when the database is placed near the users.
- ✓
Automatic scaling based on demand
Why this is correct
Automatic scaling matches the stem's demand for a DBaaS advantage: the provider's orchestration layer provisions extra compute and storage as workload rises, then deprovisions it, something an on-premises database cannot do without manual hardware procurement. This elasticity satisfies the scenario's requirement directly.
- ✗
Full control over the operating system
Why it's wrong here
DBaaS abstracts the underlying operating system, so the provider patches and manages it; customers gain no OS-level control, unlike self-managed databases on IaaS virtual machines. It is tempting because full OS control is a real advantage of running a database on your own infrastructure.
