A meteorological startup company has a custom web application to sell weather data to its users online. The company uses Amazon DynamoDB to store its data and wants to build a new service that sends an alert to the managers of four internal teams every time a new weather event is recorded The company does not want this new service to affect the performance of the current application
What should a solutions architect do to meet these requirements with the LEAST amount of operational overhead?
A. Use DynamoDB transactions to write new event data to the table Configure the transactions to notify internal teams.
B. Have the current application publish a message to four Amazon Simple Notification Service (Amazon SNS) topics. Have each team subscribe to one topic.
C. Enable Amazon DynamoDB Streams on the table Use triggers to write to a Mingle Amazon Simple Notification Service (Amazon SNS) topic to which the teams can subscribe
D. Add a custom attribute to each record to flag new items Write a cron job that scans the table every minute for items that are new and notifies an Amazon Simple Queue Service (Amazon SQS) queue to which the teams can subscribe
A company hosts its core network services, including directory services and DNS. in its on-premises data center. The data center is connected to the AWS Cloud using AWS Direct Connect (DX) Additional AWS accounts are planned that will require quick, cost-effective, and consistent access to these network services What should a solutions architect implement to meet these requirements with the LEAST amount of operational overhead?
A. Create a DX connection in each new account Route the network traffic to the on-premises servers
B. Configure VPC endpoints in the DX VPC for all required services Route the network traffic to the on-premises servers.
C. Create a VPN connection between each new account and the DX VPC, Route the network traffic to the on-premises servers
D. Configure AWS Transit Gateway between the accounts Assign DX to the transit gateway and route network traffic to the on-premises servers
A company is hosting 60 TB of production-level data in an Amazon S3 bucket A solutions architect needs to bring that data on premises for quarterly audit requirements This export of data must be encrypted while in transit The company has low network bandwidth in place between AWS and its on-premises data center.
What should the solutions architect do to meet these requirements?
A. Deploy AWS Migration Hub with 90-day replication windows for data transfer.
B. Deploy an AWS Storage Gateway volume gateway on AWS Enable a 90-day replication window to transfer the data
C. Deploy Amazon Elastic File System (Amazon EFS), with lifecycle policies enabled, on AWS. Use it to transfer the data
D. Deploy an AWS Snowball device in the on-premises data center after completing an export job request in the AWS Snowball console
A company wants to replicate its data to AWS to recover in the event of a disaster. Today, a system administrator has scripts that copy data to a NFS share Individual backup files need to be accessed with low latency by application administrators to deal with errors in processing.
What should a solutions architect recommend to meet these requirements?
A. Modify the script to copy data to an Amazon S3 bucket instead of the on-premises NFS share
B. Modify the script to copy data to an Amazon S3 Glacier Archive instead of the on-premises NFS share
C. Modify the script to copy data to an Amazon Elastic File System (Amazon EFS) volume instead of the on-premises NFS share.
D. Modify the script to copy data to an AWS Storage Gateway for File Gateway virtual appliance instead of the on-premises NFS share.
A company recently migrated a message processing system to AWS. The system receives messages into an ActiveMQ queue running on an Amazon EC2 instance. Messages are processed by a consumer application running on Amazon EC2 The consumer application processes the messages and writes results to a MySQL database running on Amazon EC2. The company wants this application to be highly available with low operational complexity Which architecture offers the HIGHEST availability?
A. Add a second ActiveMQ server to another Availability Zone Add an additional consumer EC2 instance in another Availability Zone Replicate the MySQL database to another Availability Zone.
B. Use Amazon MQ with active/standby brokers configured across two Availability Zones Add an additional consumer EC2 instance in another Availability Zone.Replicate the MySQL database to another Availability Zone
C. Use Amazon MQ with active/standby brokers configured across two Availability Zones. Add an additional consumer EC2 instance in another Availability Zone. Use Amazon RDS for MySQL with Multi-AZ enabled
D. Use Amazon MQ with active/standby brokers configured across two Availability Zones Add an Auto Scaling group for the consumer EC2 instances across two Availability Zones Use Amazon RDS for MySQL with Multi-AZ enabled.
A company has an application that ingests incoming messages. These messages are then quickly consumed by dozens of other applications and microservices. The number of messages varies drastically and sometimes spikes as high as
100.000 each second The company wants to decouple the solution and increase scalability.
Which solution meets these requirements?
A. Persist the messages to Amazon Kinesis Data Analytics All the applications will read and process the messages
B. Deploy the application on Amazon EC2 instances in an Auto Scaling group, which scales the number of EC2 instances based on CPU metrics
C. Write the messages to Amazon Kinesis Data Streams with a single shard. All applications will read from the stream and process the messages.
D. Publish the messages to an Amazon Simple Notification Service (Amazon SNS) topic with one or more Amazon Simple Queue Service (Amazon SQS) subscriptions. All applications then process the messages from the queues
A company has an ecommerce application running In a single VPC. The application stack has a single web server and an Amazon RDS Multi-AZ DB instance The company launches new products twice a month. This Increases website traffic by approximately 400% for a minimum of 72 hours During product launches, users experience slow response times and frequent timeout errors in their browsers What should a solutions architect do to mitigate the slow response times and timeout errors while minimizing operational overhead?
A. Increase the instance size of the web server.
B. Add an Application Load Balancer and an additional web server.
C. Add Amazon EC2 Auto Scaling and an Application Load Balancer
D. Deploy an Amazon ElastiCache cluster to store frequently accessed data.
A company runs a website on Amazon EC2 instances behind an ELB Application Load Balancer. Amazon Route 53 is used for the DNS. The company wants to set up a backup website with a message including a phone number and email
address that users can reach if the primary website is down.
How should the company deploy this solution?

B. Use Amazon S3 website hosting for the backup website and Route 53 latency routing policy.
C. Deploy the application in another AWS Region and use ELB health checks for failover routing.
D. Deploy the application in another AWS Region and use server-side redirection on the primary website.
A company is planning to use an Amazon DynamoDB table for data storage. The company is concerned about cost optimization. The table will not be used on most mornings in the evenings, the read and write traffic will often be
unpredictable When traffic spikes occur they will happen very quickly.
What should a solutions architect recommend?
A. Create a DynamoDB table in on-demand capacity mode.
B. Create a DynamoDB table with a global secondary Index
C. Create a DynamoDB table with provisioned capacity and auto scaling.
D. Create a DynamoDB table in provisioned capacity mode, and configure it as a global table
