Cloud scaling quiz

Medium · 6 questions

{{ answeredLabel }}

Question 1 · MCQ

A system runs on one physical server instead of a cluster. Which scaling strategy is being avoided?

Question 2 · True / False + reason

A load balancer is unnecessary when an application runs on only one machine.

Reasoning (required)

Cloud scaling quiz

36%

2 of 6 correct

Scaling vocabulary is the gap, not the scheduler.

What to review

Vertical scaling adds resources to one server; horizontal adds servers.
A single-machine deployment removes the need to distribute traffic.
➜Rewrite both definitions in your own words, then retake.

Your answers

Which scaling strategy is being avoided on a single server?

✓ Correct: Vertical scaling

✗ You said: Horizontal scaling

A load balancer is unnecessary on one machine.

✓ Correct: True, and your reasoning matched.

Which characteristic belongs to the scheduler we covered?

✓ Correct: It adjusts priorities based on task aging

✗ You said: It guarantees zero context-switch overhead

Model paper 1

5 questions · 24 marks

Q1. Define high-performance computing and its importance in cloud computing.

2 mk

Model answer. HPC uses parallel processing across many machines to solve problems that a single computer cannot finish in useful time. In the cloud it matters because that capacity can be rented per hour, so simulations and large analyses no longer need owned hardware.

Q2. What is high-throughput computing, and how does it differ from HPC?

2 mk

Model answer. HTC maximises how many independent tasks finish over days or weeks. HPC optimises the speed of one tightly-coupled job. Throughput versus latency, in short.

Q3. Explain telemedicine and its significance in cloud computing.

5 mk

Model answer. Remote diagnosis and monitoring delivered over networked services. Cloud hosting supplies the elastic storage for imaging, the compliance boundary for patient records, and the availability a clinic cannot guarantee alone.
