Q1Domain Verified
In the context of the "The Complete Scalable System Architecture Course 2026," what fundamental principle does the course emphasize when designing for eventual consistency, specifically differentiating it from strong consistency models in a distributed system?
Ensuring all replicas are updated synchronously before an operation is acknowledged, guaranteeing identical data across the system at any given moment.
Relying solely on client-side logic to manage data synchronization and conflict resolution, reducing server-side complexity.
Accepting temporary discrepancies in data across replicas, with mechanisms in place to resolve conflicts and converge towards a consistent state over time.
Prioritizing immediate data availability for all nodes, even at the cost of increased latency and potential conflicts.
Q2Domain Verified
According to "The Complete Scalable System Architecture Course 2026," when discussing load balancing strategies for a microservices architecture, what is the primary advantage of using a client-side load balancer over a server-side load balancer in terms of system autonomy and resilience?
Client-side load balancers introduce a single point of failure, making the system less robust.
Client-side load balancing distributes intelligence to the clients, allowing them to make more informed routing decisions based on real-time service health and load, thus enhancing resilience.
Server-side load balancers can more easily implement sophisticated routing algorithms like weighted round-robin and least connections.
Server-side load balancers offer centralized control, simplifying management and configuration for large clusters.
Q3Domain Verified
In the context of "The Complete Scalable System Architecture Course 2026," when designing a distributed caching strategy, what is the most significant drawback of a client-side cache compared to a distributed cache (e.g., Redis cluster) for frequently updated, shared data?
Client-side caches offer better fault tolerance as they don't rely on a central cache server.
Client-side caches have higher latency due to network round trips to the cache server.
Distributed caches require complex sharding and replication configurations that are difficult to manage.
Client-side caches are prone to stale data and cache invalidation challenges across multiple clients.
