Difficulty: HardDefine the benefits of the AWS Cloud

A digital media company is launching a live video streaming service for a major international tournament. The company expects a massive, unpredictable surge in user traffic during live matches, followed by periods of near-zero activity. The CFO requires that the company only pay for active resource usage during the tournament and avoid upfront infrastructure investments. Which of the following benefits of the AWS Cloud directly address this scenario? (Select TWO)

  1. Stop guessing capacityAnswer
  2. Trade fixed expense for variable expenseAnswer
  3. C
    Trade variable expense for fixed expense to ensure long-term budget predictability
  4. D
    Eliminate resource fluctuation by pre-provisioning peak capacity to achieve static scalability
  5. E
    Consolidate services into a single monolithic architecture to reduce system integration costs

Answer

The benefits of 'Stop guessing capacity' and 'Trade fixed expense for variable expense' directly address the requirements.
The scenario highlights two distinct requirements: handling unpredictable traffic spikes without wasting capacity, and paying only for active usage without upfront investments. The benefit of 'Stop guessing capacity' allows the system to scale dynamically to meet the exact demand of the tournament matches. The benefit of 'Trade fixed expense for variable expense' allows the company to pay only for the resources they consume rather than buying physical servers upfront.

Step-by-Step Solution

1
Analyze the operational traffic requirements.
Identify that the massive, unpredictable spikes and drops in user traffic require a system that can scale resources on demand, matching 'Stop guessing capacity' (elasticity).
This avoids both under-provisioning during peak matches and over-provisioning during idle periods.
2
Analyze the financial requirements.
Identify that the CFO's goal of paying only for active resource usage and avoiding upfront infrastructure investments matches 'Trade fixed expense for variable expense'.
This shifts cost from capital expenses (CapEx) to operating expenses (OpEx).
3
Evaluate the choices and eliminate distractors.
Confirm that the options corresponding to these two benefits are correct, while eliminating options that reverse CapEx/OpEx, advocate for static peak provisioning, or promote monolithic design.
This ensures the final answer aligns with official AWS cloud benefits and architecture best practices.

Key Concept

The six core benefits of the AWS Cloud, specifically focusing on dynamic scaling (elasticity) and the shift from capital expenses (CapEx) to operational expenses (OpEx).
