MCQs on Distributed Computing

What is the primary advantage of distributed computing?

• Higher energy efficiency

• Improved scalability

• Single point of failure

• Requires fewer resources

How does a distributed system achieve fault tolerance?

• By eliminating backup nodes

• Using a single central server

• Through data replication and load balancing

• By increasing the network latency

In a client-server architecture, what is the role of the client?

• To process all incoming requests

• To initiate requests and receive responses

• To store all application data

• To manage load balancing

Which architecture does Bitcoin use?

• Client-server

• Multitier

• Peer-to-peer (P2P)

• Event-driven

What is an advantage of a microservices architecture?

• Easier scalability

• Centralized storage

• Single point of failure

• Monolithic structure

Event-driven architectures primarily rely on:

• Request-response interactions

• On-demand code execution

• Message queues and event handlers

• Centralized databases

Which of the following protocols ensures reliable data transmission?

• UDP

• TCP

• MQTT

• CoAP

What is the main advantage of MQTT over HTTP?

• More secure connections

• Lower overhead

• Faster one-time data retrieval

• Uses RESTful APIs

Remote Procedure Call (RPC) is commonly used in:

• Static web pages

• Microservices communication

• Batch processing systems

• File storage

Push technologies such as WebSockets are useful for:

• Processing large batch files

• Real-time updates and notifications

• Increasing network latency

• Storing logs
