CSW20103 Consistency Models in Distributed Systems

In analyzing a distributed banking system, which consistency model is most appropriate to ensure immediate transaction correctness?

• Causal consistency

• Eventual consistency

• Sequential consistency

• Linearizability

Which consistency model allows users to see different orders of independent events without violating system correctness?

• Linearizability

• Sequential consistency

• Causal consistency

• Strong consistency

Evaluate which consistency model would introduce the least synchronization overhead in a chat application.

• Sequential consistency

• Linearizability

• Causal consistency

• Atomic consistency

For collaborative editing software aiming for a trade-off between latency and consistency guarantees, the most suitable consistency model is:

• Linearizability

• Sequential consistency

• Causal consistency

• Eventual consistency

Which consistency model requires operations to reflect real-time execution order strictly, increasing system complexity significantly?

• Eventual consistency

• Sequential consistency

• Linearizability

• Causal consistency

Critically analyze which scenario demonstrates causal consistency failure due to concurrency without causal relationships.

• Sequential database transactions

• Independent concurrent updates creating divergence

• Transactional banking updates

• Real-time health monitoring systems

Which consistency model is analyzed as ideal for financial transactions due to its strict ordering guarantees?

• Sequential consistency

• Linearizability

• Causal consistency

• Eventual consistency

Which scenario illustrates a case where linearizability would be unnecessarily stringent?

• Banking transaction verification

• Stock trading platforms

• Online voting systems

• Social media post updates

Assess the impact of choosing sequential consistency over causal consistency in real-time collaboration platforms.

• Higher responsiveness

• Increased consistency guarantees with moderate latency

• Significant decrease in synchronization overhead

• Complete divergence handling

Identify the tool commonly used to enforce causal consistency in distributed systems by tracking event dependencies.

• Locks

• Vector clocks

• Atomic counters

• Paxos algorithm
