Solutions Architect Professional (Page 92)

A Development team has created a series of AWS CloudFormation templates to help deploy services.They created a template for a network/virtual private cloud(VPC) stack, a database stack, a bastion host stack, and a web application-specific stack.Each service requires the deployment of at least:✑ A network/VPC stack✑ A bastion host stack✑ A web application stackEach template has multiple input parameters that make it difficult to deploy the services individually from the AWS CloudFormation console.The input parameters from one stack are typically outputs from other stacks.For example, the VPC ID, subnet IDs, and security groups from the network stack may need to be used in the application stack or database stack.Which actions will help reduce both the operational burden and the number of parameters passed into a service deployment?

A company is using AWS Organizations to manage multiple accounts.Due to regulatory requirements, the company wants to restrict specific member accounts to certain AWS Regions, where they are permitted to deploy resources.The resources in the accounts must be tagged, enforced based on a group standard, and centrally managed with minimal configuration.What should a solutions architect do to meet these requirements?Read More →

A company has an application behind a load balancer with enough Amazon EC2 instances to satisfy peak demand.Scripts and third-party deployment solutions are used to configure EC2 instances when demand increases or an instance fails.The team must periodically evaluate the utilization of the instance types to ensure that the correct sizes are deployed.How can this workload be optimized to meet these requirements?Read More →

An online gaming company needs to optimize the cost of its workloads on AWS.The company uses a dedicated account to host the production environment for its online gaming application and an analytics application.Amazon EC2 instances host the gaming application and must always be available.The EC2 instances run all year.The analytics application uses data that is stored in Amazon S3.The analytics application can be interrupted and resumed without issue.Which solution will meet these requirements MOST cost-effectively?Read More →

A solutions architect needs to migrate 50 TB of NFS data to Amazon S3.The files are on several NFS file servers on corporate network.These are dense file systems containing tens of millions of small files.The system operators have configured the file interface on an AWS Snowball Edge device and are using a shell script to copy data.Developers report that copying the data to the Snowball Edge device is very slow.The solutions architect suspects this may be related to the overhead of encrypting all the small files and transporting them over the network.Which changes can be made to speed up the data transfer?Read More →

A company runs its application on Amazon EC2 instances and AWS Lambda functions.The EC2 instances experience a continuous and stable load.The Lambda functions experience a varied and unpredictable load.The application includes a caching layer that uses an Amazon MemoryDB for Redis cluster.A solutions architect must recommend a solution to minimize the company’s overall monthly costs.Which solution will meet these requirements?Read More →

A North American company with headquarters on the East Coast is deploying a new web application running on Amazon EC2 in the us-east-1 Region.The application should dynamically scale to meet user demand and maintain resiliency.Additionally, the application must have disaster recover capabilities in an active-passive configuration with the us-west-1 Region.Which steps should a solutions architect take after creating a VPC in the us-east-1 Region?Read More →

A company is building an application that will run on an AWS Lambda function.Hundreds of customers will use the application.The company wants to give each customer a quota of requests for a specific time period.The quotas must match customer usage patterns.Some customers must receive a higher quota for a shorter time period.Which solution will meet these requirements?Read More →

A weather forecasting company is migrating an application that stores data on premises in a PostgreSQL database.The Company wants to migrate the database to Amazon Aurora PostgreSQL.The database size grows at an average rate of 5 GB daily and is currently 50 TB.The data center has an internet connection with50 Mbps of available bandwidth.The migration to AWS must be completed as soon as possible within the next 21 days.Which data transfer strategy meets these requirements with the LEAST amount of application downtime?Read More →

A company has built a high performance computing (HPC) cluster in AWS for a tightly coupled workload that generates a large number of shared files stored in Amazon EFS.The cluster was performing well when the number of Amazon EC2 instances in the cluster was 100.However, when the company increased the cluster size to 1.000 EC2 instances, overall performance was well below expectations.Which collection of design choices should a solutions architect make to achieve the maximum performance from the HPC cluster?
