A company is running an application on Amazon EC2 instances in the AWS Cloud. The application is using a MongoDB database with a replica set as its data tier. The MongoDB database is installed on systems in the company ' s on-premises data center and is accessible through an AWS Direct Connect connection to the data center environment.
A solutions architect must migrate the on-premises MongoDB database to Amazon DocumentDB (with MongoDB compatibility).
Which strategy should the solutions architect choose to perform this migration?
A company has an application that stores user-uploaded videos in an Amazon S3 bucket that uses S3 Standard storage. Users access the videos frequently in the first 180 days after the videos are uploaded. Access after 180 days is rare. Named users and anonymous users access the videos. Most of the videos are more than 100 MB in size. Users often have poor internet connectivity when they upload videos, resulting in failed uploads. The company uses multipart uploads for the videos. A solutions architect needs to optimize the S3 costs of the application. Which combination of actions will meet these requirements? (Select TWO.)
A company generates approximately 20 GB of data multiple times each day. The company uses AWS DataSync to copy all data from on-premises storage to Amazon S3 every 6 hours for further processing.
The analytics team wants to modify the copy process to copy only data relevant to the analytics team and ignore the rest of the data. The team wants to copy data as soon as possible and receive a notification when the copy process is finished.
Which combination of steps will meet these requirements MOST cost-effectively? (Select THREE.)
A company is running an application on several Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer. The load on the application varies throughout the day, and EC2 instances are scaled in and out on a regular basis. Log files from the EC2 instances are copied to a central Amazon S3 bucket every 15 minutes. The security team discovers that log files are missing from some of the terminated EC2 instances.
Which set of actions will ensure that log files are copied to the central S3 bucket from the terminated EC2 instances?
A video processing company wants to build a machine learning (ML) model by using 600 TB of compressed data that is stored as thousands of files in the company ' s on-premises network attached storage system. The company does not have the necessary compute resources on premises for ML experiments and wants to use AWS.
The company needs to complete the data transfer to AWS within 3 weeks. The data transfer will be a one-time transfer. The data must be encrypted in transit. The measured upload speed of the company ' s internet connection is 100 Mbps, and multiple departments share the connection.
Which solution will meet these requirements MOST cost-effectively?
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?
A solutions architect is auditing the security setup of an AWS Lambda function for a company. The Lambda function retrieves the latest changes from an Amazon Aurora database. The Lambda function and the database run in the same VPC. Lambda environment variables are providing the database credentials to the Lambda function.
The Lambda function aggregates data and makes the data available in an Amazon S3 bucket that is configured for server-side encryption with AWS KMS managed encryption keys (SSE-KMS). The data must not travel across the internet. If any database credentials become compromised, the company needs a solution that minimizes the impact of the compromise.
What should the solutions architect recommend to meet these requirements?
A company is using an organization in AWS Organizations to manage hundreds of AWS accounts. A solutions architect is working on a solution to provide baseline protection for the Open Web Application Security Project (OWASP) top 10 web application vulnerabilities. The solutions architect is using AWS WAF for all existing and new Amazon CloudFront distributions that are deployed within the organization.
Which combination of steps should the solutions architect take to provide the baseline protection? (Select THREE.)
A company needs to gather data from an experiment in a remote location that does not have internet connectivity. During the experiment, sensors that are connected to a total network will generate 6 TB of data in a preprimary formal over the course of 1 week. The sensors can be configured to upload their data files to an FTP server periodically, but the sensors do not have their own FTP server. The sensors also do not support other protocols. The company needs to collect the data centrally and move lie data to object storage in the AWS Cloud as soon. as possible after the experiment.
Which solution will meet these requirements?
A company is refactoring its on-premises order-processing platform in the AWS Cloud. The platform includes a web front end that is hosted on a fleet of VMs RabbitMQ to connect the front end to the backend, and a Kubernetes cluster to run a containerized backend system to process the orders. The company does not want to make any major changes to the application
Which solution will meet these requirements with the LEAST operational overhead?
A company needs to apply consistent custom security audit rules across its organization in AWS Organizations. Accounts in the organization use a single AWS Region.
The company uses AWS Config in each account with four custom rules and five managed rules. The rules must be deployed to all accounts and must not be editable by member accounts. The company wants to easily update rules in the future. All required permissions are already in place.
Which combination of steps will meet these requirements with the LEAST operational effort? (Select TWO.)
A company has an environment that has a single AWS account. A solutions architect is reviewing the environment to recommend what the company could improve specifically in terms of access to the AWS Management Console. The company ' s IT support workers currently access the console for administrative tasks, authenticating with named IAM users that have been mapped to their job role.
The IT support workers no longer want to maintain both their Active Directory and IAM user accounts. They want to be able to access the console by using their existing Active Directory credentials. The solutions architect is using AWS Single Sign-On (AWS SSO) to implement this functionality.
Which solution will meet these requirements MOST cost-effectively?
A company processes environment data. The has a set up sensors to provide a continuous stream of data from different areas in a city. The data is available in JSON format.
The company wants to use an AWS solution to send the data to a database that does not require fixed schemas for storage. The data must be send in real time.
Which solution will meet these requirements?
A company hosts a payment processing platform across multiple AWS Regions. The processing platform exposes payment processing API endpoints. The company uses Amazon Route 53 to route traffic to an Application Load Balancer (ALB) in each Region to distribute requests to backend payment gateways. The company has implemented Auto Scaling for the payment gateways.
The company needs to improve reliability and availability by handling application failures quickly.
Which solution will meet this requirement with the LEAST response time for global users?
A solutions architect works for a government agency that has strict disaster recovery requirements. All Amazon Elastic Block Store (Amazon EBS) snapshots are required to be saved in at least two additional AWS Regions. The agency also is required to maintain the lowest possible operational overhead.
Which solution meets these requirements?
