easy📝 Conceptual Q2 of 15
AWS - EC2 Fundamentals
Why is EC2 considered scalable for compute needs?
ABecause you can launch or stop instances anytime
BBecause it automatically backs up data
CBecause it encrypts all network traffic
DBecause it provides unlimited storage space
Step-by-Step Solution
Solution:

  1. Step 1: Understand scalability in EC2 context

    EC2 allows users to start or stop virtual servers on demand, adjusting compute power as needed.

  2. Step 2: Eliminate unrelated features

    Backup, encryption, and storage are handled by other AWS services, not directly related to EC2 scalability.

  3. Final Answer:

    Because you can launch or stop instances anytime -> Option A

  4. Quick Check:

    EC2 scalability = start/stop instances [OK]
Quick Trick: Scalability means flexible instance start/stop [OK]
Common Mistakes:
  • Mixing scalability with backup or encryption features
  • Assuming EC2 provides unlimited storage
  • Confusing EC2 with storage or security services
