Understanding the CAP Theorem: Key Concepts and Scenarios Quiz

1. Basic Definition

   Which three fundamental properties does the CAP theorem state are impossible to achieve simultaneously in a distributed system?

   1. Consistency, Availability, Partition Tolerance
   2. Concurrency, Accuracy, Performance
   3. Capacity, Access, Partitioning
   4. Cache, Assignment, Persistence
   5. Coherence, Assurance, Purity

2. Consistency Scenario

   If a distributed database always returns the most recent write to any read request, which CAP property is being satisfied?

   1. Consistency
   2. Aptitude
   3. Participation
   4. Accessibility
   5. Persistence

3. Availability Explained

   In the context of the CAP theorem, which property ensures that every request receives a response, even if some servers have failed?

   1. Availability
   2. Annulability
   3. Activity
   4. Amplitude
   5. Adaptability

4. Partition Tolerance Example

   Suppose a network split occurs, and the system continues to operate despite some nodes being unable to communicate; which CAP property does this system demonstrate?

   1. Partition Tolerance
   2. Partiality
   3. Persistence Toleration
   4. Provision Tolerance
   5. Participative Tolerance

5. Trade-off Understanding

   According to the CAP theorem, what must a distributed system do when a network partition occurs?

   1. Choose between Consistency and Availability
   2. Compromise on Partition Tolerance
   3. Switch to Synchronous Mode Only
   4. Ignore Client Requests
   5. Drop All Updates
