An enterprise is planning to deploy a regulatory-compliant application on AWS that requires high availability, resilience against localized physical disasters, and optimal resource distribution. Which TWO statements accurately describe the physical, logical, or networking isolation characteristics of AWS Regions and Availability Zones?
- The mapping of Availability Zone names to physical locations is randomized independently for each AWS account to ensure even resource distribution.Cevap
- Availability Zones within a single Region are physically isolated on separate floodplains and power grids, yet are connected by low-latency, redundant private fiber-optic networks.Cevap
- CEach Availability Zone serves as a distinct national data sovereignty boundary, allowing customers to meet local data residency compliance requirements by selecting specific zones.
- DAWS automatically replicates all customer data and server configurations between Availability Zones within a Region to guarantee high availability and regional disaster recovery.
- ETo maintain fault isolation, network traffic between different Availability Zones in the same Region is routed over the public internet, whereas inter-Region traffic uses the private AWS fiber backbone.
Cevap
The mapping of Availability Zone names to physical locations is randomized independently for each AWS account, and Availability Zones within a single Region are physically isolated on separate floodplains and power grids, yet connected by private fiber-optic networks.
The correct statements identify that AWS virtualizes and randomizes logical Availability Zone names to physical infrastructure independently per account to balance resource utilization, and that Availability Zones are physically isolated to prevent disaster correlation while being connected via high-speed, private networks for latency-sensitive operations.
