Amazon Web Services SAP-C02 - AWS Certified Solutions Architect - Professional
A company has deployed production workloads on Amazon EC2 On-Demand Instances and Amazon RDS for PostgreSQL DB instances in multiple environments. The company has the AWS Business Support plan. A solutions architect must optimize the cost of the workloads without negatively affecting the availability or compute capacity of the workloads. Which solution will meet these requirements?
A company is building a software-as-a-service (SaaS) solution on AWS. The company has deployed an Amazon API Gateway REST API with AWS Lambda integration in multiple AWS Regions and in the same production account.
The company offers tiered pricing that gives customers the ability to pay for the capacity to make a certain number of API calls per second. The premium tier offers up to 3,000 calls per second, and customers are identified by a unique API key. Several premium tier customers in various Regions report that they receive error responses of 429 Too Many Requests from multiple API methods during peak usage hours. Logs indicate that the Lambda function is never invoked.
What could be the cause of the error messages for these customers?
Question:
A company is replicating an application in asecondary Region. The application usesDynamoDBandRDS for MySQL. The secondary Region must function independently during adisaster.
A company has an internal application running on AWS that is used to track and process shipments in the company’s warehouse. Currently, after the system receives an order, it emails the staff the information needed to ship a package. Once the package is shipped, the staff replies to the email and the order is marked as shipped.
The company wants to stop using email in the application and move to a serverless application model.
Which architecture solution meets these requirements?
A company completed a successful Amazon Workspaces proof of concept. They now want to make Workspaceshighly available across two AWS Regions. Workspaces are deployed in the failover Region. A hosted zone is available in Amazon Route 53.
What should the solutions architect do?
A company needs to architect a hybrid DNS solution. This solution will use an Amazon Route 53 private hosted zone for the domain cloud.example.com for the resources stored within VPCs.
The company has the following DNS resolution requirements:
• On-premises systems should be able to resolve and connect to cloud.example.com.
• All VPCs should be able to resolve cloud.example.com.
There is already an AWS Direct Connect connection between the on-premises corporate network and AWS Transit Gateway. Which architecture should the company use to meet these requirements with the HIGHEST performance?
Question:
A company mandates that all internal AWS communications useprivate IPs. A solutions architect createdinterface VPC endpointsfor public AWS services like S3. However, service names are still resolving topublic IP addresses, and the internal apps cannot connect.
What should the architect do to resolve this issue?
A company is storing data in several Amazon DynamoDB tables. A solutions architect must use a serverless architecture to make the data accessible publicly through a simple API over HTTPS. The solution must scale automatically in response to demand.
Which solutions meet these requirements? (Choose two.)
Question:
A company provisions short-lived AWS accounts for students. Each account needs access to ml.p2.xlarge SageMaker instances for training and inference. The default quotas are insufficient.
How should quota increases be automated during account provisioning?
A company wants to refactor its retail ordering web application that currently has a load-balanced Amazon EC2 instance fleet for web hosting, database API services, and business logic. The company needs to create a decoupled, scalable architecture with a mechanism for retaining failed orders while also minimizing operational costs.

Which solution will meet these requirements?
A company is developing a serverless application that runs in a VPC. The VPC has public and private IPv4 subnets across multiple Availability Zones. The application connects to the internet through multiple public NAT gateways and an internet gateway.
The company must integrate the application with a new service from an external provider by using an AWS Lambda function. The external provider accepts requests from only public IPv4 addresses that are on an approved list. The company must provide connectivity details to the external provider before the application can start using the new service.
Which solution will give the application the ability to access the new service?
A global media company is planning a multi-Region deployment of an application. Amazon DynamoDB global tables will back the deployment to keep the user experience consistent across the two continents where users are concentrated. Each deployment will have a public Application Load Balancer (ALB). The company manages public DNS internally. The company wants to make the application available through an apex domain.
Which solution will meet these requirements with the LEAST effort?
A company runs a software-as-a-service < SaaS) application on AWS The application consists of AWS Lambda functions and an Amazon RDS for MySQL Multi-AZ database During market events the application has a much higher workload than normal Users notice slow response times during the peak periods because of many database connections The company needs to improve the scalable performance and availability of the database
Which solution meets these requirements ' ?
A company is running a three-tier web application in an on-premises data center. The frontend is a PHP application that is served by an Apache web server. The middle tier is a monolithic Java SE application. The storage tier is a 60 TB PostgreSQL database.
The three-tier web application recently crashed and became unresponsive. The database also reached capacity because of read operations. The company wants to migrate to AWS to resolve these issues and improve scalability,
Which combination of steps will meet these requirements with the LEAST development effort? (Select THREE.)
