A developer is building an e-commerce application which will be hosted in an ECS Cluster.
To minimize the number of instances in use, she must select a strategy which will place tasks based on the least available amount of CPU or memory.
Which of the following task placement strategy should the developer implement? binpack distinctInstance random spread.
An EBS-backed EC2 instance has been recently reported to contain a malware that could spread to your other instances.
To fix this security vulnerability, you will need to attach its root EBS volume to a new EC2 instance which hosts a security program that can scan viruses, worms, Trojan horses, or spyware.
What steps would you take to detach the root volume from the compromised EC2 instance? Stop the instance then detach the volume. Unmount the volume from the OS and then detach. Unmount the volume, stop the instance, and then detach. Detach the volume from the AWS Console. AWS takes care of unmounting the volume for you.
A single docker container environment is hosted in Elastic Beanstalk.
Your manager instructed you to ensure that the compute resources maintain full capacity during deployments to avoid any degradation of the service or possible down time.
Which of the following deployment methods should you use to satisfy the given requirement? (Select TWO.) Immutable Rolling with additional batch Canary All at once Rolling.
An application architect manages several AWS accounts for staging, testing, and production environments, which are used by several development teams.
For application deployments, the developers use the similar base CloudFormation template for their applications.
Which of the following can allow the developer to effectively manage the updates on this template across all AWS accounts with minimal effort? Update the stacks on multiple AWS accounts using CloudFormation StackSets. Define and manage stack instances on multiple AWS Accounts using CloudFormation Stack Instances. Upload the CloudFormation templates to CodeCommit and use a combination of CodeDeploy and CodePipeline to manage the deployment to multiple accounts. Create and manage stacks on multiple AWS accounts using CloudFormation Change Sets.
Due to the popularity of serverless computing, your manager instructed you to share your technical expertise to the whole software development department of your company.
You are planning to deploy a simple Node.js ‘Hello World’ Lambda function to AWS using CloudFormation.
Which of the following is the EASIEST way of deploying the function to AWS? Include your function source inline in the ZipFile parameter of the AWS::Lambda::Function resource in the CloudFormation template. Upload the code in S3 as a ZIP file then specify the S3 path in the ZipFile parameter of the AWS::Lambda::Function resource in the CloudFormation template. Include your function source inline in the Code parameter of the AWS::Lambda::Function resource in the CloudFormation template. Upload the code in S3 then specify the S3Key and S3Bucket parameters under the AWS::Lambda::Function resource in the CloudFormation template.
An Elastic Beanstalk application becomes inaccessible for several minutes whenever a failed deployment is rolled back. A developer should recommend a strategy that will have the least impact on the application’s availability if the deployment fails. Teams must be able to revert changes quickly as well.
Which deployment method should the developer suggest? Blue/Gree All at Once Rolling Rolling with Additional Batches.
An aerospace engineering company has recently migrated to AWS for their cloud architecture.
They are using CloudFormation and AWS SAM as deployment services for both of their monolithic and serverless applications.
There is a new requirement where you have to dynamically install packages, create files, and start services on your EC2 instances upon the deployment of the application stack using CloudFormation.
Which of the following helper scripts should you use in this scenario? cfn-init cfn-hup cfn-get-metadata cfn-signal.
A developer is instructed to set up a new serverless architecture composed of AWS Lambda, API Gateway, and DynamoDB in a single stack.
The new architecture should allow the developer to locally build, test, and debug serverless applications.
Which of the following should the developer use to satisfy the above requirement? AWS Serverless Application Model (AWS SAM) Elastic Beanstalk OpsWorks CloudFormation.
You developed a shell script which uses AWS CLI to create a new Lambda function. However, you received an InvalidParameterValueException after running the script.
What is the MOST likely cause of this issue? You provided an IAM role in the CreateFunction API which AWS Lambda is unable to assume. You have exceeded your maximum total code size per account. The resource already exists. The AWS Lambda service encountered an internal error.
