Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 684 discussion

"AWS Local Zones are a type of AWS infrastructure deployment that place compute, storage, database, and other select services closer to large population, industry, and IT centers, enabling you to deliver applications that require single-digit millisecond latency to end-users." A and C tell us to "deploy the applications in eu-central-1" which is exactly what we're not supposed to do. AWS Wavelength zones are AWS deployments in CSP's networks, has nothing to do with this question. https://aws.amazon.com/about-aws/global-infrastructure/localzones/features/?nc1=h_ls

AC is not right "Because of regulations, the company cannot launch some of its applications in eu-central-1" D: AWS Wavelength is for mobile network B: Local Zones can be used to launch apps close to a region but not in a region like EUC1 so this works

Correct B: AWS Local Zones are an extension of AWS infrastructure and bring AWS services closer to end-users, providing ultra-low latency for applications that require single-digit millisecond latencies. By deploying the applications in AWS Local Zones, the company can meet the latency requirements while also complying with regulations that prevent certain applications from being hosted in the eu-central-1 Region.

Option B - AWS Local Zones place AWS compute, storage, database, and other select services closer to end-users. This would allow the company to deploy applications within geographic proximity to eu-central-1 without being directly in the region, potentially meeting regulatory requirements and achieving low latency. Whereas Option D - AWS Wavelength Zones are designed to provide developers the ability to build applications that deliver single-digit millisecond latencies to MOBILE and connected devices. And it's more focused on 5G Apps and may not be directly relevant to Web Apps hosting.

I would go also for B, was in doubt from B or D but I aggree with pentium75 the wavelenght zones are not designed for this use case however AWS local zones can provide single-digit milisecond latency as described in the link https://aws.amazon.com/about-aws/global-infrastructure/localzones/

option B

AWS Wavelength (Option D): AWS Wavelength Zones bring AWS services to the edge of the 5G network, providing ultra-low latency for applications that require single-digit millisecond latencies. Deploying applications in Wavelength Zones allows the company to extend its VPC from the eu-central-1 Region to the chosen Wavelength Zone, providing the required low-latency access.
