A company has migrated a legacy application to the AWS Cloud. The application runs on three Amazon EC2 instances that are spread across three Availability Zones. One EC2 instance is in each Availability Zone. The EC2 instances are running in three private subnets of the VPC and are set up as targets for an Application Load Balancer (ALB) that is associated with three public subnets.
The application needs to communicate with on-premises systems. Only traffic from IP addresses in the company ' s IP address range are allowed to access the on-premises systems. The company ' s security team is bringing only one IP address from its internal IP address range to the cloud. The company has added this IP address to the allow list for the company firewall. The company also has created an Elastic IP address for this IP address.
A solutions architect needs to create a solution that gives the application the ability to communicate with the on-premises systems. The solution also must be able to mitigate failures automatically.
Which solution will meet these requirements?
A company’s web application uses an Amazon API Gateway API, AWS Lambda functions, and Amazon DynamoDB global tables to handle backend requests. The web application is deployed in two AWS Regions in an active-passive model. The company uses Amazon Route 53 for DNS. The web application requires a manual DNS update to fail over to the secondary Region. An analytics Lambda function runs in the same AWS account. The function has caused Lambda concurrency to reach 90% of the current quota on an average day. A recent surge in traffic for the analytics workload resulted in throttled Lambda requests and a poor user experience for the web application users. A solutions architect must increase the reliability of the web application. The solution must use an Amazon CloudWatch alarm to send an Amazon SNS notification when the Lambda concurrency reaches a specific utilization threshold. Which solution will meet these requirements with the LEAST operational overhead?
An AWS customer has a web application that runs on premises. The web application fetches data from a third-party API that is behind a firewall. The third party accepts only one public CIDR block in each client ' s allow list.
The customer wants to migrate their web application to the AWS Cloud. The application will be hosted on a set of Amazon EC2 instances behind an Application Load Balancer (ALB) in a VPC. The ALB is located in public subnets. The EC2 instances are located in private subnets. NAT gateways provide internet access to the private subnets.
How should a solutions architect ensure that the web application can continue to call the third-parly API after the migration?
A company has Linux-based Amazon EC2 instances. Users must access the instances by using SSH with EC2 SSH Key pairs. Each machine requires a unique EC2 Key pair.
The company wants to implement a key rotation policy that will, upon request, automatically rotate all the EC2 key pairs and keep the key in a securely encrypted place. The company will accept less than 1 minute of downtime during key rotation.
Which solution will meet these requirement?
A company has an application that runs as a ReplicaSet of multiple pods in an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. The EKS cluster has nodes in multiple Availability Zones. The application generates many small files that must be accessible across all running instances of the application. The company needs to back up the files and retain the backups for 1 year.
Which solution will meet these requirements while providing the FASTEST storage performance?
A company is currently in the design phase of an application that will need an RPO of less than 5 minutes and an RTO of less than 10 minutes. The solutions architecture team is forecasting that the database will store approximately 10 TB of data. As part of the design, they are looking for a database solution that will provide the company with the ability to fail over to a secondary Region.
Which solution will meet these business requirements at the LOWEST cost?
A company needs its remote employees to access the web interface of an application. The company hosts the application in a VPC in the AWS Cloud. The application runs on a fleet of Amazon EC2 instances in private subnets across multiple Availability Zones.
The remote employees are not currently using a corporate VPN connection. Company policy does not allow a direct connection from the public internet to the application.
Which solution will meet these requirements?
A company has a legacy application that runs on multiple .NET Framework components. The components share the same Microsoft SQL Server database and
communicate with each other asynchronously by using Microsoft Message Queueing (MSMQ).
The company is starting a migration to containerized .NET Core components and wants to refactor the application to run on AWS. The .NET Core components require complex orchestration. The company must have full control over networking and host configuration. The application ' s database model is strongly relational.
Which solution will meet these requirements?
A large company runs an AWS migration assessment. Now, the company must select its first workload to migrate to AWS. The company has the following goals:
• Build cloud migration skills.
• Minimize business risk.
• Move quickly to prepare for an on-premises data center contract expiration in less than 6 months.
Which migration approach aligns with AWS guidance for selecting and migrating a first workload?
A company has loT sensors that monitor traffic patterns throughout a large city. The company wants to read and collect data from the sensors and perform aggregations on the data.
A solutions architect designs a solution in which the loT devices are streaming to Amazon Kinesis Data Streams. Several applications are reading from the stream. However, several consumers are experiencing throttling and are periodically and are periodically encountering a RealProvisioned Throughput Exceeded error.
Which actions should the solution architect take to resolve this issue? (Select THREE.)
Question:
How can applications in multiple AWS accounts privately access aPostgreSQL RDS instancein a separate AWS account, while managing the number of connections?
A company hosts a software as a service (SaaS) solution on AWS. The solution has an Amazon API Gateway API that serves an HTTPS endpoint. The API uses AWS Lambda functions for compute. The Lambda functions store data in an Amazon Aurora Serverless VI database.
The company used the AWS Serverless Application Model (AWS SAM) to deploy the solution. The solution extends across multiple Availability Zones and has nodisaster recovery (DR) plan.
A solutions architect must design a DR strategy that can recover the solution in another AWS Region. The solution has an R TO of 5 minutes and an RPO of 1 minute.
What should the solutions architect do to meet these requirements?
A company is planning to migrate an application from on premises to the AWS Cloud The company will begin the migration by moving the application underlying data storage to AWS The application data is stored on a shared tile system on premises and the application servers connect to the shared file system through SMB
A solutions architect must implement a solution that uses an Amazon S3 bucket for shared storage. Until the application is fully migrated and code is rewritten to use native Amazon S3 APIs the application must continue to have access to the data through SMB The solutions architect must migrate the application data to AWS (o its new location while still allowing the on-premises application to access the data
Which solution will meet these requirements?
A company operates a data analytics platform that uses Amazon S3 to store petabytes of customer data. The platform stores data in multiple S3 buckets across four AWS Regions. The company has configured S3 Cross-Region Replication and uses several S3 prefixes across the S3 buckets.
The company wants to analyze and visualize trends and replication metrics for its S3 storage, including for specific prefixes, over a 12-month period.
Which solution will meet these requirements with the LEAST operational overhead?
