**Add the following multiple choice questions and answers and explanations verbatim (DO NOT change the given wording). DON'T add any more questions than the multiple choice questions given below! New Question 1: "What is a significant risk associated with using a primary-replica replication system?" Choice A: "Single point of failure due to the critical nature of the primary." Choice B: "Increased read performance." Choice C: "Peers might have outdated data." Choice D: "Replication can be disrupted if a peer goes down." Correct answer: A Explanation: In a primary-replica system, the primary serves as a critical point. If it fails, the system cannot process write operations. New Question 2: "Which of the following accurately describes Peer-to-Peer replication?" Choice A: "Each node can both send and receive data from any other node." Choice B: "Only one node can initiate replication at a time." Choice C: "Peers have unequal privileges in the network." Choice D: "Nodes can only act as either clients or servers." Correct answer: A Explanation: In Peer-to-Peer replication, all nodes can act as both clients and servers, allowing any node to replicate data to any other node. New Question 3: "What is a potential drawback of replication in a primary-replica system?" Choice A: "Data on replicas might become stale due to replication lag." Choice B: "Replication is instantaneous across all nodes." Choice C: "All replicas maintain complete and updated data at all times." Choice D: "It guarantees fault tolerance at all times." Correct answer: A Explanation: Replication lag can cause changes made to the primary to take time before being reflected in the replicas, leading to stale data. New Question 4: "Which statement correctly defines a characteristic of a Peer-to-Peer network?" Choice A: "Peers synthesize from a single data source." Choice B: "All peers depend solely on a designated server for replication." Choice C: "Replication processes can only be completed in a linear sequence." Choice D: "Any node can replicate its data to any other node, promoting multi-directionality." Correct answer: D Explanation: Peer-to-Peer replication allows any node to replicate data bidirectionally with any other node, creating a multi-directional flow. New Question 5: "What is one advantage of a primary-replica replication architecture?" Choice A: "Each replica operates completely independently." Choice B: "Allows for unlimited write operations." Choice C: "Eliminates all possible points of failure." Choice D: "Can scale read operations efficiently by adding more replicas." Correct answer: D Explanation: A primary-replica architecture is able to enhance read operations by incorporating additional replicas for distributing the load. New Question 6: "What is a key characteristic of Peer-to-Peer replication?" Choice A: "It simplifies database management tasks." Choice B: "It centralizes control for easier management." Choice C: "It is robust against failures and distributes load." Choice D: "It offers extensive read scalability." Correct answer: C Explanation: Peer-to-Peer replication is designed for robustness against failures and effective load distribution, making it suitable for decentralized networks. New Question 7: "Which replication method is more suitable for traditional database applications?" Choice A: "Hybrid replication to balance benefits of both methods." Choice B: "None, as traditional databases require alternative methods." Choice C: "Primary-Replica replication due to its simplicity." Choice D: "Peer-to-Peer replication due to its decentralization." Correct answer: C Explanation: Primary-Replica replication is favored for traditional database applications because of its simplicity and read scalability. New Question 8: "When considering scalability requirements, which replication approach could be prioritized?" Choice A: "Peer-to-Peer replication for centralized control." Choice B: "Primary-Replica replication for its effective data management." Choice C: "Peer-to-Peer replication for its decentralized nature."

Correct answer: C Explanation: Peer-to-Peer replication often excels in scenarios demanding high levels of decentralization, which supports scalability. New Question 9: "What factor should influence the choice between Primary-Replica and Peer-to-Peer replication?" Choice A: "The speed of data transfer over the network." Choice B: "The computational power of client devices." Choice C: "The level of central authority in the network." Choice D: "The required scalability and fault tolerance for the application." Correct answer: D Explanation: The choice of replication method should depend on specific application requirements, particularly scalability, fault tolerance, and desired decentralization. New Question 10: "In which scenario is Peer-to-Peer replication particularly advantageous?" Choice A: "In cases where read performance is the priority." Choice B: "When applications require a centralized management system." Choice C: "If the application is limited to a single user base."
