Byzantine agreement MCQ (multiple choice questions) refer to a specific type of consensus protocol used in distributed systems. Consensus protocols are mechanisms that allow multiple nodes in a network to agree on a particular value or decision. Byzantine agreement protocols are designed to handle nodes in the network that may be malicious or faulty.
Here are some common questions and answers related to Byzantine agreement MCQ:
1. What is Byzantine agreement?
a) A type of consensus protocol for distributed systems
b) An agreement among Byzantine emperors
c) A treaty signed by the Byzantine Empire and the Ottoman Empire
d) A type of encryption algorithm
Answer: a) A type of consensus protocol for distributed systems
2. What are Byzantine failures?
a) Failures that occur only in Byzantine empires
b) Failures caused by malicious or faulty nodes in a distributed system
c) Failures caused by natural disasters in Byzantine regions
d) Failures caused by attacks from enemy empires
Answer: b) Failures caused by malicious or faulty nodes in a distributed system
3. What is the Byzantine generals problem?
a) A problem faced by Byzantine emperors during military campaigns
b) A problem related to the reliability of Byzantine architecture
c) A problem related to the trustworthiness of messages in a distributed system
d) A problem related to the availability of resources in Byzantine regions
Answer: c) A problem related to the trustworthiness of messages in a distributed system
4. What is the solution to the Byzantine generals problem?
a) Byzantine agreement protocol
b) Byzantine architecture
c) Byzantine treaty
d) Byzantine encryption algorithm
Answer: a) Byzantine agreement protocol
5. What are some examples of Byzantine agreement protocols?
a) Paxos and Raft
b) TCP and UDP
c) DNS and HTTP
d) SSH and SSL
Answer: a) Paxos and Raft
In conclusion, Byzantine agreement MCQ refers to multiple choice questions related to Byzantine agreement protocols used in distributed systems. These protocols are designed to handle nodes in the network that may be malicious or faulty, and they help achieve consensus among multiple nodes. Popular Byzantine agreement protocols include Paxos and Raft.
