Question

Difficulty: MediumAWS Global Infrastructure

A healthcare provider is deploying an electronic health record (EHR) system on AWS. The system must meet two key requirements:

1. It must serve static images, such as patient X-rays, to practitioners worldwide with minimal delay.
2. The core database must remain operational even if a physical fire or power outage disables an entire data center facility within a single geographic area.

Which of the following AWS Global Infrastructure components should the provider implement to satisfy these requirements? (Select TWO.)

  1. AWS Edge Locations to cache the static patient images closer to global usersAnswer
  2. Multiple Availability Zones within one AWS Region to host database replicas with automatic failoverAnswer
  3. C
    Multiple AWS Regions to replicate database data synchronously for protection against single data center outages
  4. D
    AWS Outposts to automatically cache the patient images across all public AWS data centers
  5. E
    A single Availability Zone with data replicated to AWS Local Zones for database high availability

Answer

The correct answers are AWS Edge Locations to cache images and multiple Availability Zones within one AWS Region.
AWS Edge Locations are the infrastructure components used by Amazon CloudFront to cache static files (like patient images) closer to users, minimizing latency. Multiple Availability Zones within a single AWS Region consist of distinct, isolated data centers with redundant infrastructure, allowing applications to remain operational even if a single facility experiences a disaster.

Step-by-Step Solution

1
Analyze the requirement for low-latency global delivery of static files.
Identify that caching content at locations physically close to users solves network latency. AWS Edge Locations serve this function by caching content close to global users.
Resolves the requirement of delivering static patient images worldwide with minimal delay.
2
Analyze the requirement for database resilience against localized facility outages.
Identify that Availability Zones are physically isolated collections of data centers within a single Region. Distributing data across multiple Availability Zones protects against localized physical disasters (like fire or power outages) at a single facility.
Resolves the requirement of keeping the database operational during a localized data center failure.

Key Concept

AWS Global Infrastructure design principles for high availability (Availability Zones) and low-latency delivery (Edge Locations).
