Question

Difficulty: Very hardDefine the benefits of the AWS Cloud

A smart grid utility company manages thousands of IoT sensors across a metropolitan area. The company is migrating its data analytics workloads to AWS. They previously struggled with provisioning hardware for winter heating demand spikes, often keeping idle physical servers online during summer. Additionally, their engineering team spent 35% of their weekly hours troubleshooting physical hardware failures and upgrading rack cabling, rather than optimizing grid algorithms. Which of the following AWS Cloud benefits directly address these specific challenges? (Select TWO.)

  1. Stop guessing capacity, allowing resources to scale dynamically with demand and eliminating idle infrastructure.Answer
  2. Stop spending money running and maintaining data centers, shifting the engineering focus from rack maintenance and physical hardware failures to core software optimization.Answer
  3. C
    Trading variable expenses for capital expenses (CapEx), allowing the utility to capitalize on physical infrastructure assets for long-term depreciation benefits.
  4. D
    Implementing elasticity by securing fixed, permanent infrastructure capacity up front to ensure the system is always prepared for maximum theoretical grid load.
  5. E
    Leveraging monolithic architecture designs to consolidate grid monitoring tools into a single tightly coupled system, reducing network traffic between components.

Answer

The correct benefits are stopping guessing capacity and stopping spending money running and maintaining data centers.
The correct answers are the benefits of stopping guessing capacity and stopping spending money running and maintaining data centers. The utility company's challenge with seasonal load variation (winter spikes vs. summer idleness) is directly resolved by stopping guessing capacity, which enables dynamic scaling in response to real-time demands. The engineering team's overhead of maintaining physical racks and resolving hardware failures is solved by stopping spending money running and maintaining data centers, which shifts these infrastructure operational tasks to AWS, allowing the engineers to focus on business-differentiating grid algorithms.

Step-by-Step Solution

1
Identify the operational issues described in the utility company's scenario.
The scenario highlights two distinct problems: (1) managing demand spikes during winter while dealing with idle server hardware during summer, and (2) engineers spending substantial time on physical server maintenance and cabling instead of developing grid algorithms.
Understanding the specific business pain points helps map them directly to the corresponding cloud benefits.
2
Map the issue of seasonal spikes and idle hardware to an AWS Cloud benefit.
The ability to scale resources dynamically up and down based on demand maps to the benefit of 'stop guessing capacity' (elasticity).
This benefit ensures resources are only active when needed, eliminating the cost of idle servers.
3
Map the issue of physical hardware maintenance and rack configuration to an AWS Cloud benefit.
Removing the burden of physical infrastructure management maps to the benefit of 'stop spending money running and maintaining data centers'.
AWS manages the underlying infrastructure, allowing the customer's technical staff to focus on strategic tasks like grid optimization.
4
Evaluate the options to identify which selections correctly describe these two benefits while avoiding common misconceptions.
The options detailing 'stop guessing capacity' and 'stop spending money running and maintaining data centers' are correct. The options involving trading variable expenses for capital expenses, fixing permanent capacity, or using monolithic architectures are incorrect.
Confirming the correct options ensures alignment with official AWS Cloud benefits and rules out distractors.
