AWS Certified DevOps Engineer - Professional Questions and Answers

Question 65

A company runs an application in an Auto Scaling group of Amazon EC2 instances behind an Application Load Balancer (ALB). The EC2 instances run Docker containers that make requests to a MySQL database that runs on separate EC2 instances. A DevOps engineer needs to update the application to use a serverless architecture. Which solution will meet this requirement with the FEWEST changes?

Options:

A.

Replace the containers that run on EC2 instances and the ALB with AWS Lambda functions. Replace the MySQL database with an Amazon Aurora Serverless v2 database that is compatible with MySQL.

B.

Replace the containers that run on EC2 instances with AWS Fargate. Replace the MySQL database with an Amazon Aurora Serverless v2 database that is compatible with MySQL.

C.

Replace the containers that run on EC2 instances and the ALB with AWS Lambda functions. Replace the MySQL database with Amazon DynamoDB tables.

D.

Replace the containers that run on EC2 instances with AWS Fargate. Replace the MySQL database with Amazon DynamoDB tables.

Question 66

A company is developing a microservices-based application on AWS. The application consists of AWS Lambda functions and Amazon Elastic Container Service (Amazon ECS) services that need to be deployed frequently.

A DevOps engineer needs to implement a consistent deployment solution across all components of the application. The solution must automate the deployments, minimize downtime during updates, and manage configuration data for the application.

Which solution will meet these requirements with the LEAST deployment effort?

Options:

A.

Use AWS CloudFormation to define and provision the Lambda functions and ECS services. Implement stack updates with resource replacement for all components. Use AWS Secrets Manager to manage the configuration data.

B.

Use AWS CodeDeploy to manage deployments for the Lambda functions and ECS services. Implement canary deployments for the Lambda functions. Implement blue/green deployments for the ECS services. Use AWS Systems Manager Parameter Store to manage the configuration data.

C.

Use AWS Step Functions to orchestrate deployments for the Lambda functions and ECS services. Use canary deployments for the Lambda functions and ECS services in a different AWS Region. Use AWS Systems Manager Parameter Store to manage the configuration data.

D.

Use AWS Systems Manager to manage deployments for the Lambda functions and ECS services. Implement all-at-once deployments for the Lambda functions. Implement rolling updates for the ECS services. Use AWS Secrets Manager to manage the configuration data.

Question 67

A DevOps engineer is building the infrastructure for an application. The application needs to run on an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that includes Amazon EC2 instances. The EC2 instances need to use an Amazon Elastic File System (Amazon EFS) file system as a storage backend. The Amazon EFS Container Storage Interface (CSI) driver is installed on the EKS cluster.

When the DevOps engineer starts the application, the EC2 instances do not mount the EFS file system.

Which solutions will fix the problem? (Select THREE.)

Options:

A.

Switch the EKS nodes from Amazon EC2 to AWS Fargate.

B.

Add an inbound rule to the EFS file system's security group to allow NFS traffic from the EKS cluster.

C.

Create an IAM role that allows the Amazon EFS CSI driver to interact with the file system.

D.

Set up AWS DataSync to configure file transfer between the EFS file system and the EKS nodes.

E.

Create a mount target for the EFS file system in the subnet of the EKS nodes.

F.

Disable encryption on the EFS file system.

Question 68

A company uses AWS Organizations, AWS Control Tower, AWS Config, and Terraform to manage its AWS accounts and resources. The company must ensure that users deploy only AWS Lambda functions that are connected to a VPC in member AWS accounts.

Which solution will meet these requirements with the LEAST operational effort?

Options:

A.

Configure AWS Control Tower to use proactive controls (guardrails). Enable optional controls implemented with AWS CloudFormation hooks for Lambda on all OUs.

B.

Create a new SCP that checks the lambda:VpcIds condition key for allowed values.

C.

Create a custom AWS Config rule to detect non-VPC-connected Lambda functions.

D.

Create a new SCP with a conditional statement that denies Lambda creation if lambda:VpcIds is null.
