Question 2

The engineering team at an e-commerce company wants to migrate from SQS Standard queues to FIFO queues with batching. As a solutions architect, which of the following steps would you have in the migration checklist? (Select three)

Question 3

A big data consulting firm needs to set up a data lake on Amazon S3 for a Health-Care client. The data lake is split in raw and refined zones. For compliance reasons, the source data needs to be kept for a minimum of 5 years. The source data arrives in the raw zone and is then processed via an AWS Glue based ETL job into the refined zone. The business analysts run ad-hoc queries only on the data in the refined zone using AWS Athena. The team is concerned about the cost of data storage in both the raw and refined zones as the data is increasing at a rate of 1TB daily in each zone. As a solutions architect, which of the following would you recommend as the MOST cost-optimal solution? (Select two)

Question 4

The engineering team at a logistics company has noticed that the Auto Scaling group (ASG) is not terminating an unhealthy Amazon EC2 instance. As a Solutions Architect, which of the following options would you suggest to troubleshoot the issue? (Select three)

Question 5

A survey company has gathered data for several years from areas in the United States. The company hosts the data in an Amazon S3 bucket that is 3 TB in size and growing. The company has started to share the data with a European marketing firm that has S3 buckets. The company wants to ensure that its data transfer costs remain as low as possible.Which solution will meet these requirements?

Question 6

A development team is looking for a solution that saves development time and deployment costs for an application that uses a high-throughput request-response message pattern. Which of the following SQS queue types is the best fit to meet this requirement?

Question 7

A company is deploying a web application and it wants to ensure that only the web tier of the application is publicly accessible. To accomplish this, the engineering team has designed the VPC with a public subnet and a private subnet. The application will be hosted on several EC2 instances in an Auto Scaling group. The team also wants TLS termination to be offloaded from the EC2 instances. Which solution should a solutions architect implement to address these requirements?

Question 8

A health care application processes the real-time health data of the patients into an analytics workflow. With a sharp increase in the number of users, the system has become slow and sometimes even unresponsive as it does not have a retry mechanism. The startup is looking at a scalable solution that has minimal implementation overhead. Which of the following would you recommend as a scalable alternative to the current solution?

Question 9

A biotechnology company has multiple High Performance Computing (HPC) workflows that quickly and accurately process and analyze genomes for hereditary diseases. The company is looking to migrate these workflows from their on-premises infrastructure to AWS Cloud. As a solutions architect, which of the following networking components would you recommend on the EC2 instances running these HPC workflows?

Question 10

A company has noticed that its EBS storage volume (io1) accounts for 90% of the cost and the remaining 10% cost can be attributed to the EC2 instance. The CloudWatch metrics report that both the EC2 instance and the EBS volume are under-utilized. The CloudWatch metrics also show that the EBS volume has occasional I/O bursts. The entire infrastructure is managed by AWS CloudFormation. As a Solutions Architect, what do you propose to reduce the costs?

Question 11

An analytics company wants to improve the performance of its big data processing workflows running on Amazon EFS. Which of the following performance modes should be used for EFS to address this requirement?

Question 12

What does this IAM policy do? { Version"": ""2012-10-17"", Statement"": [ { Sid"": ""Mystery Policy"", Action"": [ ec2:RunInstances ], Effect"": ""Allow"", Resource"": ""*"", Condition"": { StringEquals"": { aws:RequestedRegion"": ""eu-west-1 } } } ] }

Question 13

You would like to use Snowball to move on-premises backups into a long term archival tier on AWS. Which solution provides the MOST cost savings?

Question 14

A developer needs to implement a Lambda function in AWS account A that accesses an Amazon S3 bucket in AWS account B. As a Solutions Architect, which of the following will you recommend to meet this requirement?

Question 15

A silicon valley based healthcare startup uses AWS Cloud for its IT infrastructure. The startup stores patient health records on Amazon S3. The engineering team needs to implement an archival solution based on Amazon S3 Glacier to enforce regulatory and compliance controls on data access. As a solutions architect, which of the following solutions would you recommend?

Question 16

A company is looking for a technology that allows its mobile app users to connect through a Google login and have the capability to turn on MFA (Multi-Factor Authentication) to have maximum security. Ideally, the solution should be fully managed by AWS. Which technology do you recommend for managing the users' accounts?

Question 17

An e-commerce company uses a two-tier architecture with application servers in the public subnet and an RDS MySQL DB in a private subnet. The development team can use a bastion host in the public subnet to access the MySQL DB and run queries from the bastion host. However, end-users are reporting application errors. Upon inspecting application logs, the team notices several ""could not connect to server: connection timed out"" error messages. Which of the following options represent the root cause for this issue?

Question 18

A global media company uses a fleet of EC2 instances (behind an Application Load Balancer) to power its video streaming application. To improve the performance of the application, the engineering team has also created a CloudFront distribution with the Application Load Balancer as the custom origin. The security team at the company has noticed a spike in the number and types of SQL injection and cross-site scripting attack vectors on the application. As a solutions architect, which of the following solutions would you recommend as the MOST effective in countering these malicious attacks?

Question 19
