Question

Difficulty: MediumAWS Global Infrastructure

A global e-commerce company is deploying its customer-facing shopping portal on AWS. The system architecture must ensure that the web servers are resilient to localized disaster events, such as a power grid failure or flooding in a specific facility. Additionally, the company needs to cache product images and media files closer to shoppers around the world to ensure fast page load times. Which of the following AWS Global Infrastructure components should the company utilize to meet these requirements? (Select TWO)

  1. Availability Zones to host redundant application servers across isolated locations with independent power and cooling.Answer
  2. Edge Locations to cache static product images and media files closer to shoppers globally.Answer
  3. C
    AWS Regions to group server racks within a single data center facility for low-latency replication.
  4. D
    AWS Local Zones to run the core database across multiple continents to achieve automatic data sovereignty.
  5. E
    AWS Outposts to automatically cache web assets in the AWS public cloud.

Answer

The company should use Availability Zones to achieve localized fault tolerance and Edge Locations to cache content globally for reduced latency.
Availability Zones provide physical isolation and redundancy (independent power, cooling, and networking) within an AWS Region, ensuring that web servers are protected from localized disasters. Edge Locations cache static content (like product images) closer to global end-users, reducing latency for shoppers worldwide.

Step-by-Step Solution

1
Analyze the high-availability requirement for local disaster recovery.
Identify that the system needs to run in physically isolated data centers with independent power, cooling, and networking within a geographic area to survive localized failures.
This matches the definition and purpose of AWS Availability Zones.
2
Analyze the low-latency content caching requirement for global users.
Identify that a content delivery network utilizing regional edge caches is needed to store static media close to global end-users.
This matches the definition and purpose of AWS Edge Locations.
