Zorluk: OrtaAWS Global Infrastructure

An agricultural technology company is designing a smart farming platform on AWS. The architect wants to ensure that the application is highly available and resilient to localized physical disasters, while also complying with regional data residency regulations.

Which of the following statements correctly describe how the company should leverage AWS Global Infrastructure components? (Select TWO.)

  1. An Availability Zone consists of one or more discrete data centers with redundant power, networking, and connectivity within an AWS Region.Cevap
  2. Deploying the application across multiple Availability Zones in a single AWS Region protects against localized failures such as fires or power outages.Cevap
  3. C
    An Availability Zone is a geographic area that contains multiple AWS Regions connected by high-speed fiber-optic networks.
  4. D
    Each AWS Region automatically replicates all customer data to at least one other Region to ensure compliance with data sovereignty laws.
  5. E
    All Availability Zones inside a given AWS Region share the same physical infrastructure and power grid to reduce deployment latency.

Cevap

An Availability Zone consists of one or more discrete data centers with redundant power, networking, and connectivity within an AWS Region, and deploying the application across multiple Availability Zones in a single AWS Region protects against localized failures such as fires or power outages.
The correct options state that an Availability Zone consists of one or more discrete data centers with redundant power, networking, and connectivity in an AWS Region, and that deploying across multiple Availability Zones protects against localized failures. This aligns with the physical architecture of AWS, where AZs are physically isolated partitions of a Region, designed to run production applications that require high availability and fault tolerance.

Adım Adım Çözüm

1
Analyze the requirements for high availability, localized disaster resilience, and compliance with data residency regulations.
The solution must keep data within the chosen region (for compliance) while distributing components across isolated boundaries within that region to prevent localized outages from causing downtime.
This establishes the scope of AWS infrastructure needed: a single AWS Region for data residency compliance, and multiple Availability Zones for fault isolation.
2
Evaluate the relationship between AWS Regions and Availability Zones (AZs) to identify correct options.
Confirm that an AZ consists of discrete data centers within a Region, and that using multiple AZs provides localized fault isolation.
AWS Regions contain multiple AZs. AZs are physically separated and isolated from power or cooling issues affecting other zones.
3
Assess and eliminate the incorrect options.
Identify that AZs do not contain Regions, they do not share power/infrastructure, and cross-region data replication is a customer responsibility rather than an automatic AWS-managed task.
This ensures the selected answers are the only structurally and operationally correct ones.
