Sample questions from this bank

Straight from the premium CLF-C02 exams, explanation included. Judge the quality before you spend a cent.

Cloud Concepts

A startup wants to avoid large upfront hardware purchases and instead pay only for the compute capacity it actually uses each month. Which cloud computing benefit does this describe?

  • A Reduced application availability
  • B Increased time to market delays
  • C Higher fixed infrastructure costs
  • D Trading capital expense for variable expense
Show answer and explanation

Correct: D

A core benefit of cloud computing is trading capital expense (buying hardware upfront) for variable expense (paying only for what you consume). The other options describe negative outcomes that the cloud actually helps avoid, so they are incorrect.

Cloud Concepts

A company is deploying an application and wants to ensure it remains available even if a single data center fails. Which AWS concept should the architecture span to achieve this?

  • A A single edge location
  • B Multiple Availability Zones
  • C One subnet
  • D A single Availability Zone
Show answer and explanation

Correct: B

Availability Zones are physically separate data center groupings within a Region, so spanning multiple AZs protects against a single data center failure. A single AZ or subnet offers no fault isolation, and edge locations are used for content delivery, not application hosting.

Cloud Concepts

A retailer experiences large traffic spikes during holiday sales and near-zero traffic afterward. Which cloud characteristic allows them to automatically add and remove capacity to match demand?

  • A Depreciation
  • B Vendor lock-in
  • C Colocation
  • D Elasticity
Show answer and explanation

Correct: D

Elasticity is the ability to automatically scale resources up or down to match demand, which is ideal for variable traffic. Colocation and depreciation relate to traditional data centers, and vendor lock-in is a risk, not a scaling characteristic.
