Computer Systems & Networks
What could be a potential drawback of using distributed databases for storing sensitive information compared to centralized databases?
They are less capable of handling large volumes of transactions.
They don't allow for real-time access to data for users worldwide.
They often require simpler, less secure authentication methods.
They may have more points of vulnerability due to numerous nodes.
In creating an algorithm to process real-time traffic data from multiple sensors city-wide, what strategy should be prioritized to address scalability as more sensors are added?
Developing a distributed system that processes data in smaller batches close to sensor locations before aggregation.
Designing a centralized database system that collects all sensor data for batch processing every hour.
Creating a single-threaded queue that processes incoming data sequentially from all sensors.
Using round-robin scheduling on one server to handle requests from all sensors equally.
What is a security drawback of storing encrypted passwords with reversible hashing algorithms in a distributed database system?
Higher resource consumption due to complex hashing computations.
Increased server storage demands from longer hash strings.
Possibility of hash inversion attacks recovering original passwords.
Reduced performance from frequent password hash validation checks.
Considering distributed computing environments, which language feature is most critical for managing data consistency across different nodes?
Recursion in functional languages
Encapsulation in procedural languages
Inheritance in object-oriented languages
Concurrency control mechanisms
When using parallel computing, how are tasks typically managed?
A single processor handles all tasks in order.
Tasks are sent to different networks to be processed later.
Tasks are processed simultaneously.
Each task waits for the previous one to finish.
In cloud storage services that utilize distributed databases what is often improved compared to traditional local storage solutions?
Cost efficiency as more hardware resources are used for storage needs
Availability and reliability are often improved with distributed databases
Simplicity as management is spread across many different systems
Accessibility from multiple devices rather than just locally stored information
When assessing a program that uses non-deterministic algorithms in a distributed computing setting, which technique should testers use?
Solely rely on user feedback sessions identifying unexpected behaviors
Utilize static code analysis tools expecting predictable outcomes every execution run
Perform deterministic algorithm comparisons ignoring inherent non-determinism characteristics
Conduct probabilistic analysis combined with extensive simulation runs across various nodes
