A company is developing a messaging application that is based on a microservices architecture. A separate team develops each microservice by using Amazon Elastic Container Service (Amazon ECS). The teams deploy the microservices multiple times daily by using AWS CloudFormation and AWS CodePipeline.
The application recently grew in size and complexity. Each service operates correctly on its own during development, but each service produces error messages when it has to interact with other services in production. A solutions architect must improve the application's availability.
Which solution will meet these requirements with the LEAST amount of operational overhead?
A. Add an extra stage to CodePipeline for each service. Use the extra stage to deploy each service to a test environment. Test each service after deployment to make sure that no error messages occur.Which of the following components of AWS Data Pipeline specifies the business logic of your data management?
A. Task RunnerA read only news reporting site with a combined web and application tier and a database tier that receives large and unpredictable traffic demands must be able to respond to these traffic fluctuations automatically. What AWS services should be used meet these requirements?
A. Stateless instances for the web and application tier synchronized using ElastiCache Memcached in an autoscaimg group monitored with CloudWatch and RDS with read replicas.A user has created a VPC with CIDR 20.0.0.0/16. The user has created one subnet with CIDR 20.0.0.0/16 in this VPC. The user is trying to create another subnet with the same VPC for CIDR 20.0.0.1/24. What will happen in this scenario?
A. The VPC will modify the first subnet CIDR automatically to allow the second subnet IP rangeFor AWS CloudFormation, which stack state refuses UpdateStack calls?
A. UPDATE_ROLLBACK_FAILEDA company uses multiple AWS accounts in a single AWS Region A solutions architect is designing a solution to consolidate logs generated by Elastic Load Balancers (ELBs) in the AppDev, AppTest and AppProd accounts. The logs should be stored in an existing Amazon S3 bucket named s3-eib-logs in the central AWS account. The central account is used for log consolidation only and does not have ELBs deployed ELB logs must be encrypted at rest.
Which combination of steps should the solutions architect take to build the solution? (Select TWO )
A. Update the S3 bucket policy for the s3-elb-logs bucket to allow the s3 PutBucketLogging action for the central AWS account IDA company is using AWS Organizations to manage 15 AWS accounts. A solutions architect wants to run advanced analytics on the company's cloud expenditures. The cost data must be gathered and made available from an analytics account. The analytics application runs in a VPC and must receive the raw cost data each night to run the analytics.
The solutions architect has decided to use the Cost Explorer API to fetch the raw data and store the data in Amazon S3 in JSON format. Access to the raw cost data must be restricted to the analytics application. The solutions architect has already created an AWS Lambda function to collect data by using the Cost Explorer API.
Which additional actions should the solutions architect take to meet these requirements?
A. Create an IAM role in the Organizations master account with permissions to use the Cost Explorer API, and establish trust between the role and the analytics account. Update the Lambda function role and add sts:AssumeRole permissions. Assume the role in the master account from the Lambda function code by using the AWS Security Token Service (AWS STS) AssumeRole API call. Create a gateway endpoint for Amazon S3 in the analytics VPC. Create an S3 bucket policy that allows access only from the S3 endpoint.A startup company recently migrated a large ecommerce website to AWS. The website has experienced a 70% increase in sales. Software engineers are using a private GitHub repository to manage code. The DevOps team is using Jenkins for builds and unit testing. The engineers need to receive notifications for bad builds and zero downtime during deployments. The engineers also need to ensure any changes to production are seamless for users and can be rolled back in the event of a major issue.
The software engineers have decided to use AWS CodePipeline to manage their build and deployment process.
Which solution will meet these requirements?
A. Use GitHub websockets to trigger the CodePipeline pipeline. Use the Jenkins plugin for AWS CodeBuild to conduct unit testing. Send alerts to an Amazon SNS topic for any bad builds. Deploy in an in-place, all-at-once deployment configuration using AWS CodeDeploy.A company is migrating an on-premises application and a MySQL database to AWS. The application processes highly sensitive data, and new data is constantly updated in the database. The data must not be transferred over the internet. The company also must encrypt the data in transit and at rest.
The database is 5 TB in size. The company already has created the database schema in an Amazon RDS for MySQL DB instance The company has set up a 1 Gbps AWS Direct Connect connection to AWS. The company also has set up a public VIF and a private VIF. A solutions architect needs to design a solution that will migrate the data to AWS with the least possible downtime Which solution will meet these requirements?
A. Perform a database backup. Copy the backup files to an AWS Snowball Edge Storage Optimized device. Import the backup to Amazon S3. Use server-side encryption with Amazon S3 managed encryption keys (SSE-S3) for encryption at rest Use TLS for encryption in transit Import the data from Amazon S3 to the DB instance.Over which of the following Ethernet standards does AWS Direct Connect link your internal network to an AWS Direct Connect location?
A. Single mode fiber-optic cableNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
