Difficulty: EasyAWS Global Infrastructure

A database administrator is planning to configure a standby database instance to ensure application availability in case of a physical data center failure. To achieve this, the standby database should be deployed to a different isolated site within the same geographic area. Which AWS Global Infrastructure component should the administrator choose for the standby database?

  1. A
    AWS Region
  2. Availability ZoneAnswer
  3. C
    Edge Location
  4. D
    AWS Outposts

Answer

Availability Zone
The correct answer is Availability Zone. Availability Zones are isolated locations within a single AWS Region, designed to be physically separated from other Availability Zones and equipped with independent power, cooling, and network infrastructure. This design ensures that a failure in one facility does not affect others, making them the correct choice for deploying standby database instances for high availability.

Step-by-Step Solution

1
Analyze the scenario requirements
The requirement is to deploy a standby database to an isolated, physical data center location within the same geographic area to ensure high availability.
This helps identify which AWS infrastructure component provides localized physical isolation.
2
Evaluate the AWS Global Infrastructure components
Availability Zones consist of one or more discrete data centers within an AWS Region, isolated from each other to prevent concurrent failures.
This matches the criteria of isolated sites within the same geographic region.

Key Concept

Availability Zones provide physical isolation and redundancy within a single AWS Region.
