A company provides auction services for artwork and has users across North America and Europe. The company hosts its application in Amazon EC2 instances in the us-east-1 Region. Artists upload photos of their work as large-size. high-resolution image files from their mobile phones to a centralized Amazon S3 bucket created in the us-east-1 Region. The users in Europe are reporting slow performance for their image uploads.How can a solutions architect improve the performance of the image upload process?
Answer(s): C
C) S3 Transfer Acceleration improves upload performance by using Amazon CloudFront edge locations to speed up uploads to an S3 bucket. It is especially useful for large files and users who are geographically distant from the bucket's region. This solution reduces latency and speeds up the upload process for users in Europe, addressing the performance issue.
A company wants to containerize a multi-tier web application and move the application from an on-premises data center to AWS. The application includes web. application, and database tiers. The company needs to make the application fault tolerant and scalable. Some frequently accessed data must always be available across application servers. Frontend web servers need session persistence and must scale to meet increases in traffic.Which solution will meet these requirements with the LEAST ongoing operational overhead?
Answer(s): D
D) Running the application on Amazon EKS with managed node groups reduces operational overhead because AWS handles node management. Using Kubernetes deployments ensures scalability and fault tolerance. Storing session data in Amazon DynamoDB provides high availability and durability for session persistence. Additionally, using Amazon EFS to share frequently accessed data across all application tiers ensures that the application remains scalable and highly available, meeting the requirements with minimal ongoing management.
A solutions architect is planning to migrate critical Microsoft SQL Server databases to AWS. Because the databases are legacy systems, the solutions architect will move the databases to a modern data architecture. The solutions architect must migrate the databases with near-zero downtime.Which solution will meet these requirements?
C) Using native database high availability tools and connecting the source system to Amazon RDS for Microsoft SQL Server allows for replication without much downtime. After the replication is complete, transitioning the workload to the RDS instance minimizes downtime and ensures a smooth migration with near-zero interruption. This approach meets the requirement of near-zero downtime while using familiar high availability features for SQL Server.
A company's solutions architect is analyzing costs of a multi-application environment. The environment is deployed across multiple Availability Zones in a single AWS Region. After a recent acquisition, the company manages two organizations in AWS Organizations. The company has created multiple service provider applications as AWS PrivateLink-powered VPC endpoint services in one organization. The company has created multiple service consumer applications in the other organization.Data transfer charges are much higher than the company expected, and the solutions architect needs to reduce the costs. The solutions architect must recommend guidelines for developers to follow when they deploy services. These guidelines must minimize data transfer charges for the whole environment.Which guidelines meet these requirements? (Choose two.)
Answer(s): A,B
A) Using AWS Resource Access Manager to share subnets across accounts in the organization can reduce inter-Availability Zone data transfer by allowing shared access to the same resources, minimizing cross-AZ traffic and associated costs.D) Ensuring that service consumer compute resources use the Availability Zone-specific endpoint by leveraging the endpoint’s local DNS name ensures that traffic stays within the same Availability Zone, reducing cross-AZ data transfer charges, which are typically higher.These guidelines effectively minimize data transfer charges across the environment.
A company has an on-premises Microsoft SQL Server database that writes a nightly 200 GB export to a local drive. The company wants to move the backups to more robust cloud storage on Amazon S3. The company has set up a 10 Gbps AWS Direct Connect connection between the on-premises data center and AWS.Which solution meets these requirements MOST cost-effectively?
Answer(s): A
A) Deploying an AWS Storage Gateway file gateway is a cost-effective solution that enables on-premises applications to write to Amazon S3 via an SMB file share. This setup provides a simple and direct way to store the 200 GB nightly database exports in S3. It leverages the existing Direct Connect connection for faster transfers and does not require the higher cost and complexity of using Amazon FSx. The file gateway provides a seamless way to manage backups while utilizing cost-efficient S3 storage.
A company needs to establish a connection from its on-premises data center to AWS. The company needs to connect all of its VPCs that are located in different AWS Regions with transitive routing capabilities between VPC networks. The company also must reduce network outbound traffic costs, increase bandwidth throughput, and provide a consistent network experience for end users.Which solution will meet these requirements?
Answer(s): B
B) Using AWS Direct Connect with a transit VIF connected to a Direct Connect gateway provides a high-bandwidth, low-latency connection between the on-premises data center and AWS, while reducing outbound traffic costs. The Direct Connect gateway allows transitive routing between multiple VPCs across Regions by connecting to transit gateways in each Region. This setup meets the requirements for transitive routing, reduced network costs, increased bandwidth, and a consistent user experience.
A company is migrating its development and production workloads to a new organization in AWS Organizations. The company has created a separate member account for development and a separate member account for production. Consolidated billing is linked to the management account. In the management account, a solutions architect needs to create an IAM user that can stop or terminate resources in both member accounts.Which solution will meet this requirement?
D) Creating an IAM user in the management account and cross-account roles in the member accounts with least privilege access ensures that the user in the management account can assume roles in both the development and production accounts to stop or terminate resources. The trust policy in the member account roles grants the management account user access, meeting the cross-account access requirement in a secure and manageable way.
A company wants to use AWS for disaster recovery for an on-premises application. The company has hundreds of Windows-based servers that run the application. All the servers mount a common share.The company has an RTO of 15 minutes and an RPO of 5 minutes. The solution must support native failover and fallback capabilities.Which solution will meet these requirements MOST cost-effectively?
D) Using AWS Elastic Disaster Recovery to replicate on-premises servers and AWS DataSync to replicate data to an Amazon FSx for Windows File Server provides a cost-effective and reliable disaster recovery solution. This approach ensures that the RTO of 15 minutes and the RPO of 5 minutes are met by offering near real-time replication of servers and data. Elastic Disaster Recovery supports native failover and fallback capabilities, making it a suitable choice for seamless recovery and minimizing downtime during disasters.
