27Your mission is to create a lights-out datacenter environment, and you plan to use AWS OpsWorks to accomplish this. First you created a stack and added an App Server layer with an instance running in it. Next you added an application to the instance, and now you need to deploy a MySQL RDS database instance. Which of the following answers accurately describe how to add a backend database server to an OpsWorks stack? Choose 3 answers
- AAdd a new database layer and then add recipes to the deploy actions of the database and App Server layers.
- BUse OpsWorks’ “Clone Stack” feature to create a second RDS stack in another Availability Zone for redundancy in the event of a failure in the Primary AZ. To switch to the secondary RDS instance, set the [:database] attributes to values that are appropriate for your server which you can do by using custom JSON.
- CThe variables that characterize the RDS database connection—host, user, and so on—are set using the corresponding values from the deploy JSON’s [:deploy][:app_name][:database] attributes.
- DCookbook attributes are stored in a repository, so OpsWorks requires that the “password”: “your_password” attribute for the RDS instance must be encrypted using at least a 256-bit key.
- ESet up the connection between the app server and the RDS layer by using a custom recipe. The recipe configures the app server as required, typically by creating a configuration file. The recipe gets the connection data such as the host and database name from a set of attributes in the stack configuration and deployment JSON that AWS OpsWorks installs on every instance.
28You are tasked with the migration of a highly trafficked node.js application to AWS. In order to comply with organizational standards Chef recipes must be used to configure the application servers that host this application and to support application lifecycle events. Which deployment option meets these requirements while minimizing administrative burden?
- ACreate a new stack within Opsworks add the appropriate layers to the stack and deploy the application
- BCreate a new application within Elastic Beanstalk and deploy this application to a new environment
- CLaunch a Node JS server from a community AMI and manually deploy the application to the launched EC2 instance
- DLaunch and configure Chef Server on an EC2 instance and leverage the AWS CLI to launch application servers and configure those instances using Chef.
29A user has configured ELB with Auto Scaling. The user suspended the Auto Scaling AddToLoadBalancer, which adds instances to the load balancer. process for a while. What will happen to the instances launched during the suspension period?
- AThe instances will not be registered with ELB and the user has to manually register when the process is resumed
- BThe instances will be registered with ELB only once the process has resumed
- CAuto Scaling will not launch the instance during this period due to process suspension
- DIt is not possible to suspend only the AddToLoadBalancer process
30A user is running a batch process on EBS backed EC2 instances. The batch process starts a few instances to process Hadoop Map reduce jobs, which can run between 50 – 600 minutes or sometimes for more time. The user wants to configure that the instance gets terminated only when the process is completed. How can the user configure this with CloudWatch?
- ASetup the CloudWatch action to terminate the instance when the CPU utilization is less than 5%
- BSetup the CloudWatch with Auto Scaling to terminate all the instances
- CSetup a job which terminates all instances after 600 minutes
- DIt is not possible to terminate instances automatically

The user wants to now enable detailed monitoring. How can the user achieve this?- AUpdate the Launch config with CLI to set InstanceMonitoringDisabled = false
- BThe user should change the Auto Scaling group from the AWS console to enable detailed monitoring
- CUpdate the Launch config with CLI to set InstanceMonitoring.Enabled = true
- DCreate a new Launch Config with detail monitoring enabled and update the Auto Scaling group
32A web-startup runs its very successful social news application on Amazon EC2 with an Elastic Load Balancer, an Auto-Scaling group of Java/Tomcat application-servers, and DynamoDB as data store. The main web application best runs on m2.xlarge instances since it is highly memory- bound. Each new deployment requires semi-automated creation and testing of a new AMI for the application servers which takes quite a while and is therefore only done once per week. Recently, a new chat feature has been implemented in node.js and waits to be integrated in the architecture. First tests show that the new component is CPU bound Because the company has some experience with using Chef, they decided to streamline the deployment process and use AWS OpsWorks as an application life cycle tool to simplify management of the application and reduce the deployment cycles. What configuration in AWS OpsWorks is necessary to integrate the new chat module in the most cost-efficient and flexible way?
- ACreate one AWS Ops Works stack, create one AWS Ops Works layer, create one custom recipe
- BCreate one AWS Ops Works stack create two AWS Ops Works layers create one custom recipe
- CCreate two AWS Ops Works stacks create two AWS Ops Works layers create one custom recipe
- DCreate two AWS Ops Works stacks create two AWS Ops Works layers create two custom recipe
33What is required to achieve gigabit network throughput on EC2? You already selected cluster-compute, 10GB instances with enhanced networking, and your workload is already network-bound, but you are not seeing 10 gigabit speeds.
- AEnable biplex networking on your servers, so packets are non-blocking in both directions and there’s no switching overhead.
- BEnsure the instances are in different VPCs so you don’t saturate the Internet Gateway on any one VPC.
- CSelect PIOPS for your drives and mount several, so you can provision sufficient disk throughput
- DUse a placement group for your instances so the instances are physically near each other in the same Availability Zone.
34A media company produces new video files on-premises every day with a total size of around
100GBS after compression All files have a size of 1 -2 GB and need to be uploaded to Amazon S3
every night in a fixed time window between 3am and 5am Current upload takes almost 3 hours,
although less than half of the available bandwidth is used.
What step(s) would ensure that the file uploads are able to complete in the allotted time window?- AIncrease your network bandwidth to provide faster throughput to S3
- BUpload the files in parallel to S3
- CPack all files into a single archive, upload it to S3, then extract the files in AWS
- DUse AWS Import/Export to transfer the video files
35You have a web application leveraging an Elastic Load Balancer (ELB) In front of the web servers deployed using an Auto Scaling Group Your database is running on Relational Database Service (RDS) The application serves out technical articles and responses to them in general there are more views of an article than there are responses to the article.
