Distributed system characteristics and OSI

What is fault tolerance in a distributed system?

• The ability to intentionally introduce faults for testing purposes

• The system's ability to continue functioning despite hardware or software failures

• The speed at which data can be transmitted between nodes

• The capacity to distribute computing tasks evenly among nodes

What is the purpose of load balancing in a distributed system?

• To maximize the system's downtime

• To distribute tasks and resources evenly among nodes to improve performance

• To limit access to the system

• To ensure data consistency

What does scalability refer to in the context of distributed systems?

• The ability to run only on large, high-end servers

• The system's resistance to change

• The capability to handle increased workloads by adding resources

• The capacity to store vast amounts of data

Which of the following is a characteristic of distributed systems that enables data access and processing from multiple locations simultaneously?

• Transparency

• Centralization

• Monolithic architecture

• Single-point failure

What is transparency in the context of distributed systems?

• The system's ability to remain invisible to users

• The system's resistance to faults

• The capability to hide network details and complexities from users and applications

• The ability to easily identify network issues

What does the term "interoperability" mean in distributed systems?

• The ability of different systems to communicate and work together

• The security measures taken to protect data

• The ability to isolate nodes from the network

• The speed at which data is transmitted

Which characteristic of distributed systems ensures that a user's request can be processed by any available node in the network?

• Transparency

• Centralization

• Security

• Scalability

What is data consistency in a distributed system?

• The capacity to store vast amounts of data

• The ability to achieve perfect synchronization between all nodes

• The assurance that data remains unchanged and in sync across all nodes

• The speed at which data is transmitted

Which term describes the ability of a distributed system to recover from failures and continue operating without interruption?

• Scalability

• Fault tolerance

• Interoperability

• Transparency

What is a single-point failure in a distributed system?

• A situation where only one node in the system can process data

• A system that lacks transparency

• A component whose failure can bring down the entire system

• A node that is isolated from the network
