Which of the following is a characteristic of a distributed system?

• Single point of failure

• Centralized control and management

• Multiple independent computers working together

• Low complexity

Which of the following is an example of a distributed system?

• A single computer running multiple applications

• A cloud computing service

• A local area network (LAN)

• A desktop application

What does 'fault tolerance' in distributed systems refer to?

• Ability to reduce the number of system components

• Ability to recover from failures and continue operations

• Ability to increase system security

• Ability to process large volumes of data

In a distributed system, what is the purpose of a load balancer?

• To ensure data is encrypted during transmission

• To distribute incoming traffic evenly across multiple servers

• To store backup copies of data

• To provide access control to the system

Which protocol is commonly used for communication in distributed systems?

• TCP/IP

• HTTP

• FTP

• All of the above

What is 'replication' in the context of distributed systems?

• Storing multiple copies of data to increase availability and fault tolerance

• Encrypting data for security purposes

• Merging data from different sources

• Minimizing the amount of data stored

Which of the following techniques is used to ensure consistency in distributed systems?

• Eventual consistency

• Strong consistency

• Consensus algorithms

• All of the above

What does 'latency' in a distributed system refer to?

• The amount of data being transferred

• The delay between sending and receiving data

• The total number of servers in the system

• The amount of memory used by the system

What is a 'microservice' architecture in internet-based systems?

• A single, large monolithic application

• A way to break down an application into smaller, independent services

• A form of database design

• A security protocol for distributed systems

Which of the following is a key benefit of using a microservices architecture?

• Better fault isolation and scalability

• Reduced complexity in service management

• Faster development with less testing required

• All of the above
