An enterprise is planning to deploy a multi-tier web application on AWS. The application must be highly available and resilient to localized data center failures. Additionally, to comply with local regulations, all customer data must remain within the physical borders of a specific country. Which of the following statements regarding the AWS Global Infrastructure are correct? (Select TWO)
- Deploying application components across multiple Availability Zones within a single AWS Region provides high availability and fault tolerance against localized failures.Cevap
- Choosing a specific AWS Region helps meet data residency and compliance requirements by keeping data physically within that region's geographic boundaries.Cevap
- CDeploying application components across different AWS Regions is required to achieve synchronous database replication with sub-millisecond network latency.
- DEach Availability Zone represents a completely independent geographic country, allowing compliance with different national laws.
- EAWS automatically replicates all customer data across all global AWS Regions by default to ensure maximum disaster recovery.
Cevap
Deploying application components across multiple Availability Zones within a single AWS Region provides high availability and fault tolerance against localized failures; and choosing a specific AWS Region helps meet data residency and compliance requirements by keeping data physically within that region's geographic boundaries.
Deploying across multiple Availability Zones within a Region ensures protection from localized disasters because they are isolated from each other physically and utility-wise. Selecting a specific AWS Region keeps customer data physically located within that Region, directly addressing data sovereignty requirements.
