Sample questions: Emerging Technologies

10 sample questions with the correct answer and an explanation. Try to answer each one before reading the explanation.

Q1. How many emerging technologies are named in the overview of AI, cloud computing, blockchain, IoT, AR and VR, 5G, quantum computing and biotechnology if AR and VR are counted as separate technologies?

• A. Seven
• B. Nine(correct answer)
• C. Eight
• D. Ten

Answer: B.The list has AI, cloud, blockchain, IoT, AR, VR, 5G, quantum computing and biotechnology: nine when AR and VR are counted separately.

Q2. Which statement about the key emerging technologies is FALSE?

• A. Quantum computers use qubits instead of only the regular bits 0 and 1
• B. Blockchain is also used in areas such as supply chains and contracts
• C. IoT allows connected objects to send and receive data automatically
• D. Cloud needs expensive local hardware for every user(correct answer)

Answer: D.Cloud computing removes the need for expensive local hardware, so the statement that it needs hardware for every user is false.

Q3. Which description of AI matches the overview?

• A. Computers that use qubits to be both 0 and 1 at the same instant
• B. Servers that keep files and applications available to users over the internet
• C. Everyday objects that send and receive data after joining the internet
• D. Machines and software that can learn and perform tasks like human beings(correct answer)

Answer: D.AI refers to machines and software that can learn and perform like human beings; the others describe cloud, IoT and quantum computing.

Q4. Why does cloud computing reduce maintenance work for a company?

• A. The company must buy new cables every week
• B. The company must repair every server on its own
• C. The provider handles hardware upkeep(correct answer)
• D. The company must rewrite the operating system every day

Answer: C.Because resources are provided with minimal management effort or provider interaction, upkeep is mostly handled by the provider.

Q5. A cloud provider rents a virtual server to a customer who installs a database on it. Which service model is this likely to be, given that the customer controls the operating system and applications?

• A. Edge computing near the source
• B. Blockchain 2.0 with smart contracts
• C. Software as a Service model
• D. Infrastructure as a Service(correct answer)

Answer: D.IaaS offers virtual servers where users control the operating system and applications (standard knowledge on how IaaS uses virtualization).

Q6. What kind of business sees a spike in visitors during Eid or 14th August sales?

• A. An online store(correct answer)
• B. A school library
• C. A farm shop
• D. A railway station

Answer: A.The scalability example describes an online store with a huge spike in traffic during busy times like Eid or 14th August sales.

Q7. A fixed setup keeps 8 servers for 5 hours at 20 rupees per server-hour. An elastic setup uses 8 servers for 1 hour and 2 servers for 4 hours. How many rupees does elasticity save?

• A. 160
• B. 480(correct answer)
• C. 800
• D. 320

Answer: B.Fixed cost is 8 times 5 times 20 equals 800 rupees; elastic uses 8 plus 8 equals 16 server-hours, which is 320 rupees; the saving is 480 rupees.

Q8. What is the main difference between elasticity and on-demand access?

• A. Elasticity applies only to software, while on-demand access applies only to ledgers
• B. Elasticity and on-demand access are identical in meaning and use
• C. Elasticity auto-adjusts resources; on-demand is instant use(correct answer)
• D. Elasticity means waiting for setup, while on-demand access adjusts resources automatically

Answer: C.Elasticity is about automatic scaling with demand; on-demand access is about using resources whenever needed without long setup.

Q9. Moving from IaaS to PaaS to SaaS, how does the share of work done by the provider change?

• A. It shrinks at each step
• B. It is zero in all three
• C. It grows at each step(correct answer)
• D. It stays equal in all three

Answer: C.The provider takes on more responsibility at each step from IaaS to PaaS to SaaS (standard knowledge consistent with the unit).

Q10. A site runs 2 servers for 20 hours a day and 10 servers for the 4 sale hours, at 10 rupees per server-hour. What is the daily elastic cost?

• A. 480 rupees
• B. 1,000 rupees
• C. 800 rupees(correct answer)
• D. 240 rupees

Answer: C.Normal use is 2 times 20 equals 40 server-hours and the sale is 10 times 4 equals 40; 80 server-hours times 10 equals 800 rupees.
