Explain the concept of data locality in distributed computing.
Select the correct answer
Data locality is about backing up data in a local storage device.
Data locality refers to encrypting data for security.
Data locality means storing all data on a single server.
Data locality in distributed computing refers to processing data close to where it is stored to reduce latency.
What are the challenges of handling network latency in distributed systems, and what techniques can be used to mitigate latency-related issues?
Select the correct answer
Network latency can be ignored in distributed systems.
Network latency does not affect distributed systems.
Handling network latency is solely about increasing the bandwidth.
Handling network latency in distributed systems involves techniques like caching and data replication.
What are the challenges associated with managing distributed system logs, and how can these challenges be addressed?
Select the correct answer
Managing distributed system logs only involves backing up data.
Managing distributed system logs is challenging due to their volume, variety, and the need for real-time analysis.
Distributed system logs do not require real-time analysis.
Managing distributed system logs is simple due to their uniform structure.
Explain the concept of distributed tracing and its importance in monitoring and debugging microservices architectures.
Select the correct answer
Distributed tracing is a method for data backup in microservices.
Distributed tracing tracks requests as they flow through various services in a microservices architecture.
Distributed tracing is used to encrypt data across microservices.
Distributed tracing speeds up processing in microservices architectures.
Explain the concept of the Two-Phase Commit (2PC) protocol and its use in distributed transaction management.
Select the correct answer
The Two-Phase Commit (2PC) protocol ensures all nodes in a distributed system either commit or abort a transaction.
The Two-Phase Commit (2PC) protocol is a method for data backup.
The Two-Phase Commit (2PC) protocol speeds up data processing in a single-node system.
The Two-Phase Commit (2PC) protocol is used to encrypt data in a distributed system.
What is the role of a load balancer in a distributed system, and how does it work?
Select the correct answer
A load balancer distributes network or application traffic across multiple servers to ensure no single server becomes overwhelmed.
A load balancer is used to encrypt data before transmission.
A load balancer only works in single-node systems.
A load balancer stores backup data for recovery purposes.
Explain the concept of leader election in distributed systems and its role in fault tolerance.
Select the correct answer
Leader election in distributed systems determines which node will act as the coordinator for a task.
Leader election is a process of encrypting data in distributed systems.
Leader election ensures all nodes have the same processing speed.
Leader election is about backing up data in a distributed system.
Explain the concept of distributed consensus and the role of algorithms like Paxos and Raft.
Select the correct answer
Distributed consensus ensures data encryption across all nodes.
Distributed consensus is a method for data replication.
Distributed consensus is achieved when all nodes in a distributed system agree on a common state.
Distributed consensus is about achieving the highest processing speed in a distributed system.
What is a distributed lock, and why is it important in distributed systems?
Select the correct answer
A distributed lock is a backup mechanism for data recovery.
A distributed lock is used to encrypt data across multiple nodes.
A distributed lock speeds up data processing by allowing multiple processes to access the same resource.
A distributed lock ensures that only one process can access a resource at a time, preventing conflicts.
Explain the concept of eventual consistency in distributed databases.
Select the correct answer
Eventual consistency guarantees real-time data replication.
Eventual consistency ensures data is never lost in a distributed system.
Eventual consistency means that updates are immediately visible to all nodes.
Eventual consistency means that updates to a distributed database will eventually be reflected across all nodes.
Explain the concept of distributed caching and its benefits in distributed systems.
Select the correct answer
Distributed caching is a method for data encryption.
Distributed caching is used to synchronize data between different databases.
Distributed caching is a security measure to prevent data breaches.
Distributed caching stores frequently accessed data across multiple nodes to improve performance.
What is MapReduce, and how does it work in the context of distributed computing?
Select the correct answer
MapReduce is a type of database management system.
MapReduce is a networking protocol for distributed systems.
MapReduce is a file compression algorithm used in distributed systems.
MapReduce is a programming model for processing large data sets with a distributed algorithm on a cluster.
