CET CET Technology Trends and Emerging Technologies 2 — Questions and Answers
Question 1: What does 'extended reality' (XR) encompass as an umbrella term in emerging technology?
- Only virtual reality headsets
- Augmented reality, virtual reality, and mixed reality combined (Correct answer)
- Advanced display technologies for cinema
- High-resolution satellite imaging systems
Correct answer: Augmented reality, virtual reality, and mixed reality combined
Extended Reality (XR) is a collective term for AR, VR, and MR technologies that blend or replace the physical world with digital content.
Question 2: In machine learning, what is 'transfer learning' and why is it significant for emerging technologists?
- Moving trained models between cloud providers
- Applying knowledge from a pre-trained model to a new but related task (Correct answer)
- Transferring data between neural network layers
- Copying weights from one hardware chip to another
Correct answer: Applying knowledge from a pre-trained model to a new but related task
Transfer learning reuses a model trained on a large dataset as the starting point for a related task, dramatically reducing training time and data requirements.
Question 3: What is the primary purpose of a 'zero-trust' security architecture in modern technology environments?
- Eliminating all user authentication requirements
- Never automatically trusting any user or device, verifying every access request explicitly (Correct answer)
- Blocking all external network traffic by default
- Relying solely on perimeter firewalls for protection
Correct answer: Never automatically trusting any user or device, verifying every access request explicitly
Zero-trust security assumes no user or device is inherently trustworthy, requiring continuous verification of identity and context for every access request.
Question 4: Which emerging computing model uses biological molecules—primarily DNA—to store and process data at extremely high density?
- Neuromorphic computing
- Optical computing
- DNA/molecular computing (Correct answer)
- Reversible computing
Correct answer: DNA/molecular computing
DNA computing encodes data in nucleotide sequences and performs massively parallel computations through biochemical reactions, offering extraordinary storage density.
Question 5: What does 'serverless computing' mean in cloud architecture contexts?
- Computing performed without any servers in the world
- Developers deploy functions without managing underlying server infrastructure (Correct answer)
- An architecture where clients compute everything locally
- Eliminating networking hardware from data centers
Correct answer: Developers deploy functions without managing underlying server infrastructure
Serverless computing lets developers run code in response to events without provisioning or managing servers; the cloud provider handles all infrastructure automatically.
Question 6: Which term describes the convergence of operational technology (OT) and information technology (IT) in industrial and manufacturing environments?
- IT/OT convergence (Correct answer)
- SCADA modernization
- Industrial internet governance
- Cyber-physical integration
Correct answer: IT/OT convergence
IT/OT convergence connects traditional industrial control systems with modern IT networks, enabling real-time data analytics, remote monitoring, and smarter manufacturing.
