Question 191

Exam Question

A company is running a web application with On-Demand Amazon EC2 instances in Auto Scaling groups that scale dynamically based on custom metrics After extensive testing, the company determines that the m5.2xlarge instance size is optimal for the workload Application data is stored in db.r4.4xlarge Amazon RDS instances that are confirmed to be optimal. The traffic to the web application spikes randomly during the day.

What other cost-optimization methods should the company implement to further reduce costs without impacting the reliability of the application?

A. Double the instance count in the Auto Scaling groups and reduce the instance size to m5.large

B. Reserve capacity for the RDS database and the minimum number of EC2 instances that are constantly running.

C. Reduce the RDS instance size to db.r4.xlarge and add five equivalent^ sized read replicas to provide reliability.

D. Reserve capacity for all EC2 instances and leverage Spot Instance pricing for the RDS database.

Correct Answer

B. Reserve capacity for the RDS database and the minimum number of EC2 instances that are constantly running.

Explanation

People are being confused by the term ‘reserve capacity’. This is not the same as an on-demand capacity reservation. This article by AWS clearly states that by ‘reserving capacity’ you are reserving the instances and reducing your costs.

Question 192

Exam Question

A company wants to change its internal cloud billing strategy for each of its business units. Currently, the cloud governance team shares reports for overall cloud spending with the head of each business unit. The company uses AWS Organizations to manage the separate AWS accounts for each business unit. The existing tagging standard in Organizations includes the application, environment, and owner. The cloud governance team wants a centralized solution so each business unit receives monthly reports on its cloud spending. The solution should also send notifications for any cloud spending that exceeds a set threshold.

Which solution is the MOST cost-effective way to meet these requirements?

A. Configure AWS Budgets in each account and configure budget alerts that are grouped by application, environment, and owner. Add each business unit to an Amazon SNS topic for each alert. Use Cost Explorer in each account to create monthly reports for each business unit.

B. Configure AWS Budgets in the organization’s management account and configure budget alerts that are grouped by application, environment, and owner. Add each business unit to an Amazon SNS topic for each alert. Use Cost Explorer in the organization’s management account to create monthly reports for each business unit.

C. Configure AWS Budgets in each account and configure budget alerts that are grouped by application, environment, and owner. Add each business unit to an Amazon SNS topic for each alert. Use the AWS Billing and Cost Management dashboard in each account to create monthly reports for each business unit.

D. Enable AWS Cost and Usage Reports in the organization’s management account and configure reports grouped by application, environment. and owner. Create an AWS Lambda function that processes AWS Cost and Usage Reports, sends budget alerts, and sends monthly reports to each business unit’s email list.

Correct Answer

Question 193

Exam Question

A company is running an event ticketing platform on AWS and wants to optimize the platform’s cost-effectiveness. The platform is deployed on Amazon Elastic Kubernetes Service (Amazon EKS) with Amazon EC2 and is backed by an Amazon RDS for MySQL DB instance. The company is developing new application features to run on Amazon EKS with AWS Fargate.

The platform experiences infrequent high peaks in demand. The surges in demand depend on event dates.

Which solution will provide the MOST cost-effective setup for the platform?

A. Purchase Standard Reserved Instances for the EC2 instances that the EKS cluster uses in its baseline load. Scale the cluster with Spot Instances to handle peaks. Purchase 1-year All Upfront Reserved Instances for the database to meet predicted peak load for the year.

B. Purchase Compute Savings Plans for the predicted medium load of the EKS cluster. Scale the cluster with On-Demand Capacity Reservations based on event dates for peaks. Purchase 1-year No Upfront Reserved Instances for the database to meet the predicted base load. Temporarily scale out database read replicas during peaks.

C. Purchase EC2 Instance Savings Plans for the predicted base load of the EKS cluster. Scale the cluster with Spot Instances to handle peaks. Purchase 1-year All Upfront Reserved Instances for the database to meet the predicted base load. Temporarily scale up the DB instance manually during peaks.

D. Purchase Compute Savings Plans for the predicted base load of the EKS cluster. Scale the cluster with Spot Instances to handle peaks. Purchase 1-year All Upfront Reserved Instances for the database to meet the predicted base load. Temporarily scale up the DB instance manually during peaks.

Correct Answer

Explanation

They all mention using spot instances and EKS based on EC2. A spot instance is not appropriate for a production server and the company is developing new application designed for AWS Fargate, which means we must plan the future cost improvement including AWS Fargate.

Question 194

Exam Question

A company has an application that runs on Amazon EC2 instances. A solutions architect is designing VPC infrastructure in an AWS Region where the application needs to access an Amazon Aurora DB Cluster. The EC2 instances are all associated with the same security group. The DB cluster is associated with its own security group.

The solutions architect needs to add rules to the security groups to provide the application with least privilege access to the DB Cluster.

Which combination of steps will meet these requirements? (Choose two.)

A. Add an inbound rule to the EC2 instances’ security group. Specify the DB cluster’s security group as the source over the default Aurora port.

B. Add an outbound rule to the EC2 instances’ security group. Specify the DB cluster’s security group as the destination over the default Aurora port.

C. Add an inbound rule to the DB cluster’s security group. Specify the EC2 instances’ security group as the source over the default Aurora port.

D. Add an outbound rule to the DB cluster’s security group. Specify the EC2 instances’ security group as the destination over the default Aurora port.

E. Add an outbound rule to the DB cluster’s security group. Specify the EC2 instances’ security group as the destination over the ephemeral ports.

Correct Answer

A. Add an inbound rule to the EC2 instances’ security group. Specify the DB cluster’s security group as the source over the default Aurora port.

C. Add an inbound rule to the DB cluster’s security group. Specify the EC2 instances’ security group as the source over the default Aurora port.

Explanation

Adding an inbound rule to the EC2 instances’ security group and specifying the DB cluster’s security group as the source over the default Aurora port will allow the application running on the EC2 instances to access the DB cluster over the default Aurora port. And adding an inbound rule to the DB cluster’s security group and specifying the EC2 instances’ security group as the source over the default Aurora port will allow the DB cluster to receive connections from the application running on the EC2 instances.

C. Use AWS Systems Manager to re-provision the infrastructure for each deployment Update the Amazon EC2 user data to pull the latest code art-fact from Amazon S3 and use Amazon Route 53 weighted routing to point to the new environment

D. Roll out At application updates as pan of an Auto Scaling event using prebuilt AMIs. Use new versions of the AMIs to add instances, and phase out all instances that use the previous AMI version with the configured termination policy during a deployment event.

Correct Answer

B. Specify AWS Elastic Beanstak to sage in a secondary environment as the deployment target for the CI/CD pipeline of the application. To deploy swap the staging and production environment URLs.

Explanation

It is the fastest when it comes to rollback and deploying changes every hour

Question 197

Exam Question

A company is using AWS CloudFormation to deploy its infrastructure. The company is concerned that, if a production CloudFormation stack is deleted, important data stored in Amazon RDS databases or Amazon EBS volumes might also be deleted.

How can the company prevent users from accidentally deleting data in this way?

A. Modify the CloudFormation templates to add a DeletionPolicy attribute to RDS and EBS resources.

B. Configure a stack policy that disallows the deletion of RDS and EBS resources.

C. Modify IAM policies lo deny deleting RDS and EBS resources that are tagged with an “aws:cloudformation:stack-name” tag.

D. Use AWS Config rules to prevent deleting RDS and EBS resources.

Correct Answer

A. Modify the CloudFormation templates to add a DeletionPolicy attribute to RDS and EBS resources.

Explanation

With the DeletionPolicy attribute you can preserve or (in some cases) backup a resource when its stack is deleted. You specify a DeletionPolicy attribute for each resource that you want to control. If a resource has no DeletionPolicy attribute, AWS CloudFormation deletes the resource by default. To keep a resource when its stack is deleted, specify Retain for that resource. You can use retain for any resource. For example, you can retain a nested stack, Amazon S3 bucket, or EC2 instance so that you can continue to use or modify those resources after you delete their stacks.

C. Use AWS Organizations and AWS CloudFormation StackSets. Deploy a Cloud Formation template from an account that has the necessary IAM permissions.

D. Use nested stacks with AWS CloudFormation templates. Change the Region by using nested stacks.

Correct Answer

C. Use AWS Organizations and AWS CloudFormation StackSets. Deploy a Cloud Formation template from an account that has the necessary IAM permissions.

Question 199

Exam Question

An adventure company has launched a new feature on its mobile app. Users can use the feature to upload their hiking and rafting photos and videos anytime. The photos and videos are stored in Amazon S3 Standard storage in an S3 bucket and are served through Amazon CloudFront.

The company needs to optimize the cost of the storage. A solutions architect discovers that most of the uploaded photos and videos are accessed infrequently after 30 days. However, some of the uploaded photos and videos are accessed frequently after 30 days. The solutions architect needs to implement a solution that maintains millisecond retrieval availability of the photos and videos at the lowest possible cost.

Which solution will meet these requirements?

A. Configure S3 Intelligent-Tiering on the S3 bucket.

B. Configure an S3 Lifecycle policy to transition image objects and video objects from S3 Standard to S3 Glacier Deep Archive after 30 days.

C. Replace Amazon S3 with an Amazon Elastic File System (Amazon EFS) file system that is mounted on Amazon EC2 instances.

D. Add a Cache-Control: max-age header to the S3 image objects and S3 video objects. Set the header to 30 days.

Correct Answer

B. Configure an S3 Lifecycle policy to transition image objects and video objects from S3 Standard to S3 Glacier Deep Archive after 30 days.

Explanation

Amazon S3 Intelligent-Tiering is a storage class that automatically moves objects between two access tiers based on changing access patterns. Objects that are accessed frequently are stored in the frequent access tier and objects that are accessed infrequently are stored in the infrequent access tier. This allows for cost optimization without requiring manual intervention. This makes it an ideal solution for the scenario described, as it can automatically move objects that are infrequently accessed after 30 days to a lower-cost storage tier while still maintaining millisecond retrieval availability.

Question 200
