Level 2 Quiz:
Real-Time Analytics Builder Badge

1. What is a key challenge when combining high ingest rates with complex queries?

Storage capacity

Query syntax limitations

Resource contention

Data encryption

2. Why is horizontal scalability important for analytics platforms?

It simplifies SQL syntax

It allows systems to grow with data volume and users

It removes the need for indexes

It guarantees zero latency

3. Why do fast-changing query patterns create problems in traditional systems?

Queries become too short

Indexes must be constantly redesigned

Storage formats break

SQL becomes unusable

4. What is the main benefit of automatic indexing?

Lower storage costs

Reduced query complexity for users

Better adaptability to evolving workloads

Elimination of distributed systems

5. How does schema flexibility help analytics teams?

It prevents data validation

It allows data models to evolve without downtime

It reduces ingestion speed

It enforces strict column types

6. Why is fault tolerance critical in real-time analytics platforms?

Because queries are optional

Because data loss is acceptable

Because failures must not interrupt ingestion or queries

Because clusters never scale

7. Which workload characteristic is most demanding for analytics systems?

Low ingest and low query volume

High ingest and low query concurrency

High ingest and high query concurrency

Low ingest and static queries

8. What advantage does SQL provide at scale?

It replaces distributed systems

It avoids schema design

It allows complex analytics without custom code

It limits query expressiveness

9. Why are pre-aggregated cubes often limiting?

They are too fast

They reduce storage usage

They restrict analytical flexibility

They eliminate schema changes

10. What does elastic scalability allow teams to do?

Lock cluster size permanently

Scale systems up or down as demand changes

Avoid distributed deployments

Disable fault tolerance

11. Which architectural principle supports both scale and resilience?

Single-node processing

Tight coupling of components

Distributed, shared-nothing design

Manual failover
