Reviewer for Long Test 1.2 (Parts I and II)

AI Fundamentals in the Philippine Context. Maria uses BPI's chatbot BEA to check her savings account balance. BEA quickly provides the information and suggests opening a junior savings account. What best describes how BEA processes Maria's banking questions?

• BEA remembers Maria from previous conversations and knows her personal banking preferences.

• BEA recognizes patterns in Maria's words to match them with programmed responses about banking services.

• BEA genuinely understands Maria's financial needs like a human bank teller would.

• BEA feels concerned about Maria's savings and wants to help her save more money.

Answer explanation

BEA operates by identifying patterns in language input and matching them to pre-programmed banking responses, demonstrating pattern recognition rather than genuine understanding. This exemplifies how AI systems process information through algorithms without actual comprehension of banking concepts or human needs.

Big Data Application in Local Agriculture. IRRI collects weather patterns, soil conditions, crop yields, and pest reports from 10,000 farms across the Philippines. To predict the best rice varieties for next season, which Big Data characteristic is MOST important?

• Collecting data as fast as possible from all the farms.

• Having the largest possible amount of data stored in their computers.

• Storing all historical data from the past 50 years.

• Analyzing relationships between different data types to find meaningful patterns for predictions.

Answer explanation

Big Data's value comes from analyzing diverse data types (variety) and finding patterns within them, not just accumulating large volumes. IRRI needs to understand relationships between weather, soil, and yields to make accurate predictions for farmers.

Machine Learning in Healthcare. A Philippine hospital uses a system that improves its dengue outbreak predictions after analyzing each new case. The system wasn't explicitly programmed with outbreak patterns but learned them from data. This demonstrates which technology relationship?

• Machine Learning replaces all AI functions in modern healthcare systems.

• Machine Learning operates independently without any AI framework or support.

• Machine Learning is a specialized subset of AI that enables systems to improve through experience.

• Machine Learning and AI work as completely separate, unrelated technologies.

Answer explanation

Machine Learning represents a specific branch within AI that focuses on systems learning from data patterns rather than following fixed rules. The dengue system exemplifies ML's ability to improve predictions through experience while operating within the broader AI framework.

Cloud Computing Infrastructure. During a typhoon, Baguio City schools lose internet connectivity. Students can still work on their documents using Google Docs in offline mode. What does this demonstrate about Cloud Computing?

• Cloud Computing never requires an internet connection for any of its features.

• Students are no longer using Cloud Computing when working offline.

• Cloud services can provide offline functionality, syncing changes when internet connectivity returns.

• Offline mode means the cloud servers are installed locally in the school.

Answer explanation

Cloud Computing services like Google Docs can cache data locally for offline use, then synchronize with cloud servers when connectivity resumes. This hybrid approach ensures productivity during internet outages while maintaining cloud benefits.

IoT Implementation in Smart Cities. Your barangay installs smart streetlights that adjust brightness based on pedestrian movement. The devices use default passwords and unencrypted data transmission. What security action should the barangay prioritize to protect this IoT system?

• Assume the manufacturer has built-in security, so no action is needed.

• Immediately change default passwords and implement encrypted communication protocols for all devices.

• Wait until a security problem occurs before taking any protective measures.

• Focus only on physical security by putting locks on the streetlight poles.

Answer explanation

IoT devices often ship with weak default security settings that hackers can exploit. Changing default passwords and enabling encryption are essential first steps to secure smart city infrastructure from cyber attacks and unauthorized access.

Integration of Multiple Technologies. A dengue prevention system collects mosquito population data (IoT sensors), analyzes patterns using algorithms (ML), stores information remotely (Cloud), and recommends interventions (AI). How do these technologies work together?

• The technologies operate in isolation, never sharing data or processes between systems.

• Each technology contributes its specialized function to create an integrated solution more powerful than individual parts.

• Only one technology does the actual work while others provide backup support.

• The technologies compete with each other to provide the best solution.

Answer explanation

Modern solutions integrate multiple emerging technologies synergistically, where IoT collects data, Cloud provides storage and processing power, ML identifies patterns, and AI generates actionable recommendations. This interconnected approach creates comprehensive solutions impossible with single technologies.

Digital Collaboration Principles. During your online group project, Juan's message "That's interesting" receives different interpretations from team members. Some think he's excited, others believe he's being sarcastic. What does this situation demonstrate about digital communication?

• Digital messages lack vocal tone and body language, making intended meaning harder to interpret accurately.

• Written messages are naturally superior to spoken communication for clarity.

• Digital communication always conveys meaning more clearly than face-to-face conversations.

• Team members need better internet connections to understand messages properly.

Answer explanation

Digital communication removes non-verbal cues like tone of voice and facial expressions that help convey meaning in face-to-face interactions. This absence can lead to misinterpretation, requiring more explicit and careful message construction online.

Security Protocols in Team Collaboration. Your science team uses Google Docs for your project, but work isn't progressing. Members edit without coordination, overwrite each other's sections, and miss deadlines. What primary action would improve your digital collaboration?

• Reduce the team size so fewer people need to collaborate.

• Establish clear roles, communication protocols, and version control practices for coordinated teamwork.

• Stop using digital tools and meet only in person instead.

• Switch to a more expensive collaboration platform with better features.

Answer explanation

Effective digital collaboration requires explicit coordination strategies including defined roles, communication norms, and systematic work processes. Simply having collaborative tools doesn't ensure productivity without intentional team management and agreed-upon working methods.

Ethical Decision-making. Your team's shared folder contains research data for a competition. Everyone uses strong passwords, but the folder is set to "Anyone with the link can edit," and team members discuss sensitive strategies in public chat channels. What describes this security situation?

• Public sharing settings don't matter when passwords are strong enough.

• Strong passwords alone are insufficient when sharing settings and communication channels expose sensitive information.

• Security only matters for the final submission, not during collaboration.

• The strong passwords provide complete security regardless of other settings.

Answer explanation

Comprehensive security requires multiple layers including strong passwords, appropriate sharing permissions, and secure communication channels. Even strong passwords cannot protect data exposed through overly permissive sharing settings or unsecured communication platforms.

Data Privacy in Collaborative Environments. Ana set her project folder to "View only" for classmates last month. Today, she needs them to add their research data. What does Ana need to understand about managing collaborative platform permissions?

• Once set, permissions cannot be changed to maintain security consistency.

• Permission changes are unnecessary if team members remain the same.

• Initial permission settings automatically adjust themselves based on project progress.

• Permission settings should be regularly reviewed and adjusted based on current collaboration needs and project phases.

Answer explanation

Digital collaboration requires dynamic permission management that evolves with project needs. Settings appropriate for initial planning may need adjustment during active collaboration, then restriction again during final submission, reflecting changing security and access requirements.
