Worked practice questions

Cloud service use is typically charged on which basis?

  1. Pay per use
  2. Pay per unit
  3. Pay per user
  4. Pay per update
Show answer and solution

Correct answer: A. Pay per use

1. Cloud resources are consumed rather than bought outright. 2. Charging follows consumption. 3. Typically this is done on a pay-per-use or charge-per-use basis. 4. So the answer is pay per use. _Source: NIST SP 800-146, 'Cloud Computing Synopsis and Recommendations'_

The ability to quickly request, receive and later release resources is:

  1. Endurance
  2. Elasticity
  3. Efficiency
  4. Eligibility
Show answer and solution

Correct answer: B. Elasticity

1. Capacity in a cloud is not fixed at purchase. 2. It can grow and shrink on demand. 3. Elasticity is the ability for customers to quickly request, receive and later release resources. 4. So the answer is elasticity. _Source: NIST SP 800-146, 'Cloud Computing Synopsis and Recommendations'_

Cloud service costs are generally incurred gradually over a:

  1. Billing period
  2. Backup period
  3. Booking period
  4. Bidding period
Show answer and solution

Correct answer: A. Billing period

1. A cloud bill is not a single purchase price. 2. Usage accumulates before the invoice falls due. 3. Cloud service costs are generally incurred gradually over a billing period. 4. The fee is due at the period's end. _Source: NIST SP 800-146, 'Cloud Computing Synopsis and Recommendations'_
