2. You are in charge of designing a Cloud formation template which deploys a LAMP stack. After deploying a stack . you see that the status of the stack Is showing as CREATE_COMPLETE, but the apache server is still not up and running and is experiencing issues while starting up. You want to ensure that the stack creation only shows the status of CREATE_COMPLETE after all resources defined in the stack are up and running. How can you achieve this? Choose 2 answers from the options given below.(Select 2answers)

A) Define a stack policy which defines that all underlying resources should be up and running before showin, > status of CREATE_COMPLETE.
B) Use the CFN helper scripts to signal once the resource configuration is complete.
C) Use the Creation Policy to ensure it is associated with the EC2 Instance resource.
D) Use lifecycle hooks to mark the completion of the creation and configuration of the underlying resource.



3. A gaming company adopted AWS(Amazon Web Service) Cloud Formation to automate load-testing of their games. They have created an AWS(Amazon Web Service) Cloud Formation template for each gaming environment and one for the load-testing stack. The load-testing stack creates an Amazon Relational Database Service (RDS) Postgres database and two web servers running on Amazon Elastic Compute Cloud (EC2) that send HTTP requests, measure response times, and write the results into the database. A test run usually takes between 15 and 30 minutes. Once the tests are done, the AWS(Amazon Web Service) Cloud Formation stacks are torn down immediately. The test results written to the Amazon RDS database must remain accessible for visualization and analysis. Select possible solutions that allow access to the test results after the AWS(Amazon Web Service) Cloud Formation load -testing stack is deleted. Choose 2 answers. Please select:(Select 2answers)

A) Define a deletion policy of type Snapshot for the Amazon RDS resource to assure that the RDS database can be restored after the AWS(Amazon Web Service) Cloud Formation stack is deleted.
B) Define an update policy to prevent deletion of the Amazon RDS database after the AWS(Amazon Web Service) Cloud Formation stack is deleted.
C) Define an Amazon RDS Read-Replica in the load-testing AWS(Amazon Web Service) Cloud Formation stack and define a dependency relation between master and replica via the Depends On attribute.
D) Define a deletion policy of type Retain for the Amazon RDS resource to assure that the RDS database Is not deleted with the AWS(Amazon Web Service) Cloud Formation stack.
E) Define automated backups with a backup retention period of 30 days for the Amazon RDS database and perform point-in-time recovery of the database after the AWS(Amazon Web Service) Cloud Formation stack is deleted.


4. You were just hired as a Dev Ops Engineer for a startup. Your startup uses AWS(Amazon Web Service) for 100% of their infrastructure. They currently have no automation at all for deployment, and they have had many failures while trying to deploy to production. The company has told you deployment process risk mitigation is the most important thing now, and you have a lot of budget for tools and AWS(Amazon Web Service) resources. Their stack includes a 2-tier API with data stored in Dynamo DB or 53, depending on type. The Compute layer is EC2 in Auto Scaling Groups. They use Route53 for DNS pointing to an ELB. An ELB balances load across the EC2 instances. The scaling group properly varies between 4 and 12 EC2 servers. Which of the following approaches, given this company's stack and their priorities, best meets the company's needs? Please select:

A) Model the stack in AWS(Amazon Web Service) Ops Works as a single Stack, with 1 compute layer and its associated ELB. Use Chef and App Deployments to automate Rolling Deployment.
B) Model the stack in 1 Cloud Formation template. to ensure consistency and dependency graph resolution. Write deployment and integration testing automation following Rolling Deployment methodologies.
C) Model the stack In three templates: Data layer. compute layer, and networking layer. Write stack deployment and integration testing automation following Blue-Green methodologies.
D) Model the stack in AWS(Amazon Web Service) Elastic Beanstalk as a single Application with multiple Environments. Use Elastic Beanstalk?s Rolling Deploy option to progressively roll out application code changes when promoting across environments.



5. You are currently using SQS to pass messages to EC2 Instances. You need to pass messages which are greater than 5 MB in size. Which of the following can help you accomplish this.

A) Use AWS(Amazon Web Service) EFS as a shared pool storage medium. Store file system pointers to the files on disk in the SQS message bodies.
B) Use SQSs support for message partitioning and multi-part uploads on Amazon 53.
C) Use Kinesis as a buffer stream for message bodies. Store the checkpoint id for the placement in the Kinesis Stream In SQS.
D) Use the Amazon SQS Extended Client Library for Java and Amazon S3 as a storage mechanism for message bodies.
