Difficulty: EasyAWS Global Infrastructure

An architect is designing an infrastructure strategy. The strategy requires copying database backups to a distant geographic location for disaster recovery compliance. Additionally, the application's active web servers must run in multiple isolated locations within the same area to prevent downtime from a single facility outage. Which two AWS Global Infrastructure components should the architect use to meet these requirements?

  2. Availability ZonesAnswer
  3. C
    Edge Locations
  4. D
    AWS Local Zones
  5. E
    AWS Outposts

Answer

AWS Regions and Availability Zones
AWS Regions provide the separate geographic boundaries needed for disaster recovery compliance by isolating workloads across different physical locations globally. Availability Zones provide high availability within a region by grouping discrete, isolated data centers with redundant power and networking, protecting against a single facility outage.

Step-by-Step Solution

1
Identify the requirement for replicating data to a distant geographic location for disaster recovery compliance.
AWS Regions represent geographically distinct locations, making them the correct component for large-scale geographic separation.
Data sovereignty and regional disaster recovery are typically addressed by using multiple AWS Regions.
2
Identify the requirement for running active web servers in multiple isolated locations within the same area to prevent single-facility downtime.
Availability Zones consist of one or more discrete, isolated data centers within a single AWS Region.
Distributing workloads across multiple Availability Zones protects the application from the outage of a single physical facility.

Key Concept

AWS Global Infrastructure components, specifically the distinction between AWS Regions (geographic isolation) and Availability Zones (datacenter-level isolation).
