In distributed systems, what does the CAP theorem primarily address?

• Data redundancy and backup strategies

• Scalability and performance trade-offs

• The trade-offs between consistency, availability, and partition tolerance

• The relationship between processing speed and memory usage

What is the primary purpose of a service mesh in a microservices architecture?

• To centralize user authentication across applications

• To replace the need for an API gateway

• To manage service-to-service communication, including load balancing and

  security

• To store configuration settings for distributed services

In a microservices environment, what is the main role of an API gateway?

• To directly connect clients to databases

• To serve as a caching layer for all services

• To manage virtual machine deployments

• To route client requests to the appropriate microservice and handle cross-

  cutting concerns

What is a common architectural approach to enhance security in a multi-tier

application?

• Merging all application layers into a single monolithic unit

• Implementing peer-to-peer connectivity among all tiers

• Segregating the application into separate layers with dedicated security

  controls

• Consolidating databases into one central repository

In distributed databases, which consistency model permits temporary

inconsistencies between replicas while ensuring eventual uniformity?

• Strict consistency

• Linear consistency

• Eventual consistency

• Causal consistencу

What is the primary benefit of edge computing in modern IT architecture?

• Centralizing all data processing in a remote data center

• Eliminating the need for cloud services

• Processing data closer to the source to reduce latency and bandwidth usage

• Increasing the complexity of the network design
