Question # 125

A solutions architect is reviewing an application's resilience before launch. The applicationruns on an Amazon EC2 instance that is deployed in a private subnet of a VPC.The EC2 instance is provisioned by an Auto Scaling group that has a minimum capacity of Iand a maximum capacity of I. The application stores data on an Amazon RDS for MySQLDB instance. The VPC has subnets configured in three Availability Zones and is configuredwith a single NAT gateway.The solutions architect needs to recommend a solution to ensure that the application willoperate across multiple Availability Zones.Which solution will meet this requirement?

A. Deploy an additional NAT gateway in the other Availability Zones. Update the routetables with appropriate routes. Modify the RDS for MySQL DB instance to a Multi-AZconfiguration. Configure the Auto Scaling group to launch instances across AvailabilityZones. Set the minimum capacity and maximum capacity of the Auto Scaling group to 3.
B. Replace the NAT gateway with a virtual private gateway. Replace the RDS for MySQLDB instance with an Amazon Aurora MySQL DB cluster. Configure the Auto Scaling groupto launch instances across all subnets in the VPC. Set the minimum capacity andmaximum capacity of the Auto Scaling group to 3.
C. Replace the NAT gateway with a NAT instance. Migrate the RDS for MySQL DBinstance to an RDS for PostgreSQL DB instance. Launch a new EC2 instance in the otherAvailability Zones.
D. Deploy an additional NAT gateway in the other Availability Zones. Update the route tables with appropriate routes. Modify the RDS for MySQL DB instance to turn onautomatic backups and retain the backups for 7 days. Configure the Auto Scaling group tolaunch instances across all subnets in the VPC. Keep the minimum capacity and themaximum capacity of the Auto Scaling group at 1.


Question # 126

A company is running an application on premises. The application uses a set of webservers that host a static React-based single-page application (SPA), a Node.js API, and aMYSQL database server. The database is read intensive. The company will need toexpand the database's storage at an unpredictable rate.The company must migrate the application to AWS. The company also must modernize thearchitecture to reduce infrastructure management and increase scalability.Which solution will meet these requirements with the LEAST operational overhead?

A. Use AWS Database Migration Service (AWS DMS) to migrate the database to AmazonRDS for MySQL. Use AWS Application Migration Service to migrate the web application toa fleet of Amazon EC2 instances behind an Elastic Load Balancing (ELB) load balancer.Use a Spot Fleet with a request type of request to host the API.
B. Use AWS Database Migration Service (AWS DMS) to migrate the database to AmazonAurora MySQL. Copy the web files to an Amazon S3 bucket and set up web hosting. Copythe API code to AWS Lambda functions. Configure Amazon API Gateway to point to theLambda functions.
C. Use AWS Database Migration Service (AWS DMS) to migrate the database to a MySQLdatabase that runs on Amazon EC2 instances. Use AWS DataSync to migrate the web files and API files to an Amazon FSx for Windows File Server file system. Set up a fleet of EC2instances in an Auto Scaling group as web servers. Mount the FSx for Windows File Serverfile system.
D. Use AWS Application Migration Service to migrate the database to Amazon EC2instances. Copy the web files to containers that run on Amazon Elastic Kubernetes Service(Amazon EKS). Set up an Elastic Load Balancing (ELB) load balancer for the EC2instances and EKS containers. Copy the API code to AWS Lambda functions. ConfigureAmazon API Gateway to point to the Lambda functions.


Question # 127

A company has AWS accounts that are in an organization in AWS rganizations. Thecompany wants to track Amazon EC2 usage as a metric.The company's architecture team must receive a daily alert if the EC2 usage is more than10% higher than the average EC2 usage from the last 30 days.Which solution will meet these requirements?

A. Configure AWS Budgets in the organization's management account. Specify a usagetype of EC2 running hours. Specify a daily period. Set the budget amount to be 10% morethan the reported average usage for the last 30 days from AWS Cost Explorer.
B. Configure an alert to notify the architecture team if the usage threshold is met. ConfigureAWS Cost Anomaly Detection in the organization's management account. Configure amonitor type of AWS Service. Apply a filter of Amazon EC2. Configure an alert subscriptionto notify the architecture team if the usage is 10% more than the average usage for the last30 days.

Question # 130

A software as a service (SaaS) company uses AWS to host a service that is powered byAWS PrivateLink. The service consists of proprietary software that runs on three AmazonEC2 instances behind a Network Load Balancer (NL B). The instances are in privatesubnets in multiple Availability Zones in the eu-west-2 Region. All the company'scustomers are in eu-west-2. However, the company now acquires a new customer in the us-east-I Region. Thecompany creates a new VPC and new subnets in us-east-I. The company establishesinter-Region VPC peering between the VPCs in the two Regions.The company wants to give the new customer access to the SaaS service, but thecompany does not want to immediately deploy new EC2 resources in us-east-IWhich solution will meet these requirements?

A. Configure a PrivateLink endpoint service in us-east-I to use the existing NL B that is ineu-west-2. Grant specific AWS accounts access to connect to the SaaS service.

C. Create an Application Load Balancer (ALB) in front of the EC2 instances in eu-west-2.Create an NLB in us-east-I . Associate the NLB that is in us-east-I with an ALB target groupthat uses the ALB that is in eu-west-2. Configure a PrivateLink endpoint service that usesthe NLB that is in us-east-I . Grant specific AWS accounts access to connect to the SaaSservice.
D. Use AWS Resource Access Manager (AWS RAM) to share the EC2 instances that arein eu-west-2. In us-east-I , create an NLB and an instance target group that includes theshared EC2 instances from eu-west-2. Configure a PrivateLink endpoint service that usesthe NL B that is in us-east-I. Grant specific AWS accounts access to connect to the SaaSservice.
