An AWS CloudFormation template creates an Amazon RDS instance. This template is used to build up development environments as needed and then delete the stack when the environment is no longer required. The RDS-persisted data must be retained for further use, even after the CloudFormation stack is deleted.
How can this be achieved in a reliable and efficient way?
  • A. Write a script to continue backing up the RDS instance every five minutes
  • B. Create an AWS Lambda function to take a snapshot of the RDS instance, and manually execute the function before deleting the stack
  • C. Use the Snapshot Deletion Policy in the CloudFormation template definition of the RDS instance
  • D. Create a new CloudFormation template to perform backups of the RDS instance, and run this template before deleting the stack

A SysOps Administrator needs to report on Amazon EC2 instance cost by both project and environment (production, staging, development).
Which action would impact the operations team the LEAST?
  • A. For each project and environment, create a new AWS account and link them to the master payer for unified management and billing
  • B. Use AWS Organizations to create a new organization for each project, then for each environment use a separate linked AWS account
  • C. Implement cost allocation tagging in the Billing and Cost Management console to implement tags to identify resources by project and environment
  • D. Add the project and environment information to the instance metadata so that the values can be queried and rolled up into reports

A SysOps Administrator receives reports of an Auto Scaling group failing to scale when the nodes running Amazon Linux in the cluster are constrained by high memory utilization.
What should the Administrator do to enable scaling to better adapt to the high memory utilization?
  • A. Create a custom script that pipes memory utilization to Amazon S3, then, scale with an AWS Lambda-powered event
  • B. Install the Amazon CloudWatch memory monitoring scripts, and create a custom metric based on the script's results
  • C. Increase the minimum size of the cluster to meet memory and application load demands
  • D. Deploy an Application Load Balancer to more evenly distribute traffic among nodes

A Content Processing team has notified a SysOps Administrator that their content is sometimes taking a long time to process, whereas other times it processes quickly. The Content Processing submits messages to an Amazon Simple Queue Service (Amazon SQS) queue, which details the files that need to be processed.
An Amazon EC2 instance polls the queue to determine which file to process next.
How could the Administrator maintain a fast but cost-effective processing time?
  • A. Attach an Auto Scaling policy to the Amazon SQS queue to increase the number of EC2 instances based on the depth of the SQS queue
  • B. Create an Auto Scaling policy to increase the number of EC2 instances polling the queue and a CloudWatch alarm to scale based on MaxVisibility Timeout
  • C. Attach an Auto Scaling policy to the SQS queue to scale instances based on the depth of the dead-letter queue
  • D. Create an Auto Scaling policy to increase the number of EC2 instances polling the queue and a CloudWatch alarm to scale based on ApproximateNumberOfMessagesVisible

A Development team has an application stack consisting of many OS dependencies and language runtime dependencies. When deploying the application to production, the most important factor is how quickly the instance is operational.
What deployment methodology should be used to update the running environments to meet the requirement?
  • A. Use fully baked AMIs (ג€golden imagesג€) created after each successful build, creating a new Auto Scaling group, and blue/green deployments with rollbacks.
  • B. Use user-data scripts to configure the instance correctly on boot by installing all dependencies when needed.
  • C. Use an AWS Lambda function to only update the application locally on each instance, then re-attach it to the load balancer when the process complete.
  • D. Use AWS OpsWorks scripts to execute on reboot of each instance to install all known dependencies, then re-attach the instances to the load balancer.

A mobile application must allow users to securely access their own content stored in a shared Amazon S3 bucket.
Which AWS services should be used to enable this access? (Choose two.)
  • A. AWS Directory Service
  • B. AWS Shield
  • C. IAM roles
  • D. Amazon Cognito
  • E. AWS Organizations

A Systems Administrator is planning to deploy multiple EC2 instances within two separate Availability Zones in the same AwS Region. The instances cannot be exposed to the Internet, but must be able to exchange traffic between one another. The data does not need to be encrypted.
What solution meets these requirements while maintaining the lowest cost?
  • A. Create two private subnets within the same VPC. Communicate between instances using their private IP addresses
  • B. Create 2 public subnets within the same VPC. Communicate between instances using their public IP addresses
  • C. Create 2 separate VPCs, one for each Availability Zone. Create a private subnet within each VPC. Create a static route table pointing the destination CIDR to the other VPC
  • D. Create 2 separate VPCs, one for each Availability Zone and create a public subnet in each. Deploy a VPN appliance within each VPC and establish a VPN tunnel between them. Communicate between instances by routing traffic through the VPN appliances

The SysOps Administrator must integrate an existing on-premises asymmetrical key management system into an AWS services platform.
How can the Administrator meet this requirement?
  • A. Implement AWS KMS and integrate with the existing on-premises asymmetrical key management system
  • B. Implement AWS CloudHSM and integrate it with the existing key management infrastructure
  • C. Deploy an Amazon EC2 instance and choose an AMI from an AWS partner in the AWS Marketplace
  • D. Create a master key in AWS KMS, and export that key to the existing on-premises asymmetrical key management system

The amount of data a company must back up has been increasing, and storage space is quickly running out. There is no budget to purchase new backup software that is capable of backing up data directly to the cloud.
What is the MOST cost-effective way to make storage available to the company's legacy backup system?
  • A. Launch an Amazon EC2 instance, add large Amazon EBS volumes, and connect using VPN
  • B. Ship backup tapes to AWS for storage in secure AWS Availability Zones
  • C. Use AWS Snowball on a weekly basis to transfer data to Amazon Glacier
  • D. Use AWS Storage Gateway to present a VTL using iSCSI to the legacy application

In IAM, can you attach more than one inline policy to a particular entity such a user, role, or group?
  • A. No
  • B. Yes
  • C. Yes, you can but only if you attach the policy within a VPC.
  • D. Yes, you can but only if you attach the policy within the GovCloud.
