AWS Certified Solutions Architect - Associate SAA-C03
A company has an application that runs on Amazon EC2 instances and uses an Amazon Aurora database. The EC2 instances connect to the
database by using user names and passwords that are stored locally in a file. The company wants to minimize the operational overhead of
credential management.
What should a solutions architect do to accomplish this goal?
Use AWS Secrets Manager. Turn on automatic rotation. Most Voted
Use AWS Systems Manager Parameter Store. Turn on automatic rotation.
Create an Amazon S3 bucket to store objects that are encrypted with an AWS Key Management Service (AWS KMS) encryption key. Migrate
the credential file to the S3 bucket. Point the application to the S3 bucket.
Create an encrypted Amazon Elastic Block Store (Amazon EBS) volume for each EC2 instance. Attach the new EBS volume to each EC2
instance. Migrate the credential file to the new EBS volume. Point the application to the new EBS volume.
A global company hosts its web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The web application has static
data and dynamic data. The company stores its static data in an Amazon S3 bucket. The company wants to improve performance and reduce
latency for the static data and dynamic data. The company is using its own domain name registered with Amazon Route 53.
What should a solutions architect do to meet these requirements?
Create an Amazon CloudFront distribution that has the S3 bucket and the ALB as origins. Configure Route 53 to route traffic to the
CloudFront distribution. Most Voted
Create an Amazon CloudFront distribution that has the ALB as an origin. Create an AWS Global Accelerator standard accelerator that has
the S3 bucket as an endpoint Configure Route 53 to route traffic to the CloudFront distribution.
Create an Amazon CloudFront distribution that has the S3 bucket as an origin. Create an AWS Global Accelerator standard accelerator that
has the ALB and the CloudFront distribution as endpoints. Create a custom domain name that points to the accelerator DNS name. Use the
custom domain name as an endpoint for the web application.
Create an Amazon CloudFront distribution that has the ALB as an origin. Create an AWS Global Accelerator standard accelerator that has
the S3 bucket as an endpoint. Create two domain names. Point one domain name to the CloudFront DNS name for dynamic content. Point the
other domain name to the accelerator DNS name for static content. Use the domain names as endpoints for the web application.
A company performs monthly maintenance on its AWS infrastructure. During these maintenance activities, the company needs to rotate the
credentials for its Amazon RDS for MySQL databases across multiple AWS Regions.
Which solution will meet these requirements with the LEAST operational overhead?
Store the credentials as secrets in AWS Secrets Manager. Use multi-Region secret replication for the required Regions. Configure Secrets
Manager to rotate the secrets on a schedule. Most Voted
Store the credentials as secrets in AWS Systems Manager by creating a secure string parameter. Use multi-Region secret replication for the
required Regions. Configure Systems Manager to rotate the secrets on a schedule.
Store the credentials in an Amazon S3 bucket that has server-side encryption (SSE) enabled. Use Amazon EventBridge (Amazon
CloudWatch Events) to invoke an AWS Lambda function to rotate the credentials.
Encrypt the credentials as secrets by using AWS Key Management Service (AWS KMS) multi-Region customer managed keys. Store the
secrets in an Amazon DynamoDB global table. Use an AWS Lambda function to retrieve the secrets from DynamoDB. Use the RDS API to
rotate the secrets.
A company runs an ecommerce application on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2
Auto Scaling group across multiple Availability Zones. The Auto Scaling group scales based on CPU utilization metrics. The ecommerce
application stores the transaction data in a MySQL 8.0 database that is hosted on a large EC2 instance.
The database's performance degrades quickly as application load increases. The application handles more read requests than write transactions.
The company wants a solution that will automatically scale the database to meet the demand of unpredictable read workloads while maintaining
high availability.
Which solution will meet these requirements?
Use Amazon Redshift with a single node for leader and compute functionality.
Use Amazon RDS with a Single-AZ deployment Configure Amazon RDS to add reader instances in a different Availability Zone.
Use Amazon Aurora with a Multi-AZ deployment. Configure Aurora Auto Scaling with Aurora Replicas. Most Voted
Use Amazon ElastiCache for Memcached with EC2 Spot Instances.
A company recently migrated to AWS and wants to implement a solution to protect the traffic that flows in and out of the production VPC. The
company had an inspection server in its on-premises data center. The inspection server performed specific operations such as traffic flow
inspection and traffic filtering. The company wants to have the same functionalities in the AWS Cloud.
Which solution will meet these requirements?
Use Amazon GuardDuty for traffic inspection and traffic filtering in the production VPC.
Use Traffic Mirroring to mirror traffic from the production VPC for traffic inspection and filtering.
Use AWS Network Firewall to create the required rules for traffic inspection and traffic filtering for the production VPC. Most Voted
Use AWS Firewall Manager to create the required rules for traffic inspection and traffic filtering for the production VPC.
