A cloud engineer is in charge of deploying a platform in an laaS public cloud. The application tracks the state using session cookies, and there are no affinity restrictions. Which of the following…

Question

Options

• AResource metering
• BReserved resources
• CDedicated host
• DPay-as-you-go model

• A
  2% (1)
• B
  6% (3)
• C
  9% (5)
• D
  83% (45)

Explanation

With no session affinity restrictions, the application can route requests to any available instance, enabling horizontal auto-scaling. The pay-as-you-go model charges only for the compute resources actually consumed, making it ideal for variable or unpredictable workloads - you scale up during peak demand and scale down (and stop paying) during low demand. Reserved resources require an upfront commitment regardless of actual usage, which is cost-effective only for stable, predictable workloads. A dedicated host is the most expensive option. Resource metering is simply tracking usage, not a cost-reduction strategy. Pay-as-you-go aligns cost directly with consumption, minimizing monthly expenses.
