A business wants to run its workload across multiple isolated data center facilities within a single geographic area to achieve high availability. Which of the following describe the characteristics of these isolated facilities? (Select TWO).
- They are physically isolated from one another within the geographic area and connected by redundant, low-latency linksCevap
- They are designed with independent power, cooling, and network connectivity to prevent fault propagationCevap
- CThey are situated globally in different countries to comply with local data sovereignty laws
- DThey function as local caching sites situated at the perimeter of the global network to reduce latency
- EThey represent virtual instances that dynamically scale in response to changing user traffic demand
Cevap
The correct answers are the options stating that the facilities are physically isolated from one another within the geographic area and connected by redundant, low-latency links, and that they are designed with independent power, cooling, and network connectivity to prevent fault propagation.
The correct options accurately describe AWS Availability Zones. Each Availability Zone consists of one or more discrete data centers, each with redundant and independent power, cooling, and network infrastructure. They are physically isolated from other zones within the same Region to prevent fault propagation, yet they remain connected to one another through low-latency, redundant fiber-optic networking to support high-performance applications and data replication.
