Zorluk: ZorAWS Global Infrastructure

An enterprise is designing a regulatory-compliant application on AWS. The application must achieve high availability across multiple physical facilities, support single-digit millisecond latency for users in a remote metropolitan city, and ensure that customer data remains strictly within national borders. Which TWO of the following statements correctly describe how the AWS Global Infrastructure handles these requirements? (Select TWO.)

  1. Deploying the workload across multiple Availability Zones in a single AWS Region provides physical separation between data centers while keeping data within the same national boundary.Cevap
  2. AWS Local Zones can be used to run latency-sensitive applications closer to end-users in the remote metropolitan city, while maintaining a connection to the parent AWS Region.Cevap
  3. C
    AWS automatically mirrors all customer database transactions to a secondary AWS Region by default to prevent data loss, while maintaining local compliance constraints.
  4. D
    AWS Edge Locations can host instances of Amazon Relational Database Service (Amazon RDS) to store local user data and satisfy the single-digit millisecond latency requirement.
  5. E
    Deploying application servers across different Availability Zones within a single Region ensures that the application is distributed across multiple distinct geographic countries.

Cevap

Deploying the workload across multiple Availability Zones in a single AWS Region provides physical separation between data centers while keeping data within the same national boundary, and AWS Local Zones can be used to run latency-sensitive applications closer to end-users in the remote metropolitan city, while maintaining a connection to the parent AWS Region.
The correct options correctly describe the functions of Availability Zones and Local Zones. Multiple Availability Zones within one Region provide redundant, physically isolated power and cooling domains to guarantee high availability while keeping data inside the same country to meet data residency rules. AWS Local Zones place compute and storage services close to metropolitan areas to satisfy low-latency demands for local users.

Adım Adım Çözüm

1
Analyze the high availability and data sovereignty requirement.
Identify that Availability Zones within a single Region provide physical redundancy (isolation from failures) while remaining within the same geographic/political border.
Availability Zones are designed with independent infrastructure (power, cooling, network) but reside in the same Region, satisfying both physical separation and local residency needs.
2
Analyze the low-latency metropolitan user requirement.
Identify that AWS Local Zones extend the parent Region to place AWS resources physically closer to metropolitan areas, achieving single-digit millisecond latency.
Edge locations are for content caching (CDN) rather than full database deployment, whereas Local Zones support running compute and database workloads closer to local end-users.
3
Evaluate and eliminate incorrect infrastructure options.
Eliminate options claiming automatic cross-region replication, database hosting in Edge Locations, or cross-country distribution of Availability Zones within a single Region.
These claims misrepresent the role and capabilities of Edge Locations, Availability Zones, and the AWS Shared Responsibility Model.

Anahtar Kavram

AWS Global Infrastructure components (Regions, Availability Zones, Local Zones, and Edge Locations) serve distinct roles in resiliency, latency, and compliance.
