Question 1 of 20
An Auto Scaling group of Amazon EC2 instances behind an Elastic Load Balancer (ELB) is running in an Amazon VPC. Health checks are configured on the ASG to use EC2 status checks. The ELB has determined that an EC2 instance is unhealthy and has removed it from service. A Solutions Architect noticed that the instance is still running and has not been terminated by EC2 Auto Scaling.
What would be an explanation for this behavior?CorrectIncorrect
Question 2 of 20
An Auto Scaling Group is unable to respond quickly enough to load changes resulting in lost messages from another application tier. The messages are typically around 128KB in size.
What is the best design option to prevent the messages from being lost?CorrectIncorrect
Question 3 of 20
An organization has a data lake on Amazon S3 and needs to find a solution for performing in-place queries of the data assets in the data lake. The requirement is to perform both data discovery and SQL querying, and complex queries from a large number of concurrent users using BI tools.
What is the BEST combination of AWS services to use in this situation? (Select TWO.)CorrectIncorrect
Question 4 of 20
A Solutions Architect enabled Access Logs on an Application Load Balancer (ALB) and needs to process the log files using a hosted Hadoop service. What configuration changes and services can be leveraged to deliver this requirement?CorrectIncorrect
Question 5 of 20
A company is deploying a big data and analytics workload. The analytics will be run from a fleet of thousands of EC2 instances across multiple AZs. Data needs to be stored on a shared storage layer that can be mounted and accessed concurrently by all EC2 instances. Latency is not a concern however extremely high throughput is required.
What storage layer would be most suitable for this requirement?CorrectIncorrect
Question 6 of 20
You are building an application that will collect information about user behavior. The application will rapidly ingest large amounts of dynamic data and requires very low latency. The database must be scalable without incurring downtime. Which database would you recommend for this scenario?CorrectIncorrect
Question 7 of 20
An application you are designing receives and processes files. The files are typically around 4GB in size and the application extracts metadata from the files which typically takes a few seconds for each file. The pattern of updates is highly dynamic with times of little activity and then multiple uploads within a short period of time.
What architecture will address this workload the most cost efficiently?CorrectIncorrect
Question 8 of 20
An Architect is designing a serverless application that will accept images uploaded by users from around the world. The application will make API calls to back-end services and save the session state data of the user to a database.
Which combination of services would provide a solution that is cost-effective while delivering the least latency?CorrectIncorrect
Question 9 of 20
A research company is developing a data lake solution in Amazon S3 to analyze huge datasets. The solution makes infrequent SQL queries only. In addition, the company wants to minimize infrastructure costs.
Which AWS service should be used to meet these requirements?CorrectIncorrect
Question 10 of 20
A retail organization is deploying a new application that will read and write data to a database. The company wants to deploy the application in three different AWS Regions in an active-active configuration. The databases need to replicate to keep information in sync.
Which solution best meets these requirements?CorrectIncorrect
Question 11 of 20
A data-processing application runs on an i3.large EC2 instance with a single 100 GB EBS gp2 volume. The application stores temporary data in a small database (less than 30 GB) located on the EBS root volume. The application is struggling to process the data fast enough, and a Solutions Architect has determined that the I/O speed of the temporary database is the bottleneck.
What is the MOST cost-efficient way to improve the database response times?CorrectIncorrect
Question 12 of 20
An application launched on Amazon EC2 instances needs to publish personally identifiable information (PII) about customers using Amazon SNS. The application is launched in private subnets within an Amazon VPC.
Which is the MOST secure way to allow the application to access service endpoints in the same region?CorrectIncorrect
Question 13 of 20
A solutions Architect is designing a new workload where an AWS Lambda function will access an Amazon DynamoDB table.
What is the MOST secure means of granting the Lambda function access to the DynamoDB table?CorrectIncorrect
Question 14 of 20
An ecommerce website runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The application is stateless and elastic and scales from a minimum of 10 instances, up to a maximum of 200 instances. For at least 80% of the time at least 40 instances are required.
Which solution should be used to minimize costs?CorrectIncorrect
Question 15 of 20
A solutions architect is designing an application on AWS. The compute layer will run in parallel across EC2 instances. The compute layer should scale based on the number of jobs to be processed. The compute layer is stateless. The solutions architect must ensure that the application is loosely coupled and the job items are durably stored.
Which design should the solutions architect use?CorrectIncorrect
Question 16 of 20
A company runs a web application that serves weather updates. The application runs on a fleet of Amazon EC2 instances in a Multi-AZ Auto scaling group behind an Application Load Balancer (ALB). The instances store data in an Amazon Aurora database. A solutions architect needs to make the application more resilient to sporadic increases in request rates.
Which architecture should the solutions architect implement? (Select TWO.)CorrectIncorrect
Question 17 of 20
An Amazon VPC contains several Amazon EC2 instances. The instances need to make API calls to Amazon DynamoDB. A solutions architect needs to ensure that the API calls do not traverse the internet.
How can this be accomplished? (Select TWO.)CorrectIncorrect
Question 18 of 20
A company have 500 TB of data in an on-premises file share that needs to be moved to Amazon S3 Glacier. The migration must not saturate the company’s low-bandwidth internet connection and the migration must be completed within a few weeks.
What is the MOST cost-effective solution?CorrectIncorrect
Question 19 of 20
A web application has recently been launched on AWS. The architecture includes two tier with a web layer and a database layer. It has been identified that the web server layer may be vulnerable to cross-site scripting (XSS) attacks.
What should a solutions architect do to remediate the vulnerability?CorrectIncorrect
Question 20 of 20
A company is planning a migration for a high performance computing (HPC) application and associated data from an on-premises data center to the AWS Cloud. The company uses tiered storage on premises with hot high-performance parallel storage to support the application during periodic runs of the application, and more economical cold storage to hold the data when the application is not actively running.
Which combination of solutions should a solutions architect recommend to support the storage needs of the application? (Select TWO.)CorrectIncorrect
