AWS Certified Solutions Architect - Associate (SAA-C03) Questions and Answers

Question 73

An application has performance issues due to increased demand. The demand is on read-only historical records in Amazon RDS using custom queries. The company wants improved performance without changing database structure and with minimal management overhead.

Which approach meets the requirement?

Options:

A.

Deploy DynamoDB and move all data.

B.

Deploy Amazon ElastiCache (Redis OSS) and cache application data.

C.

Deploy Memcached on EC2 and cache data.

D.

Deploy DynamoDB Accelerator (DAX) on Amazon RDS.

Question 74

A transaction-processing company has weekly batch jobs that run on Amazon EC2 instances in an Auto Scaling group. Transaction volume varies, but CPU utilization is always at least 60% during the batch runs. Capacity must be provisioned 30 minutes before the jobs begin.

Engineers currently scale the Auto Scaling group manually. The company needs an automated solution but cannot allocate time to analyze scaling trends.

Which solution will meet these requirements with the least operational overhead?

Options:

A.

Create a dynamic scaling policy based on CPU utilization at 60%.

B.

Create a scheduled scaling policy. Set desired, minimum, and maximum capacity. Set recurrence weekly. Set the start time to 30 minutes before the jobs run.

C.

Create a predictive scaling policy that forecasts CPU usage and pre-launches instances 30 minutes before the jobs run.

D.

Create an EventBridge rule that invokes a Lambda function when CPU reaches 60%. The Lambda function increases the Auto Scaling group size by 20%.

Question 75

A solutions architect creates an Auto Scaling group for a memory-intensive application. The solutions architect wants to scale up and scale down based on memory usage. Which solution will meet this requirement?

Options:

A.

Install and configure the AWS Systems Manager Agent (SSM Agent). Create a step scaling policy that has step adjustments based on the memory usage trend.

B.

Install and configure the Amazon CloudWatch agent. Create a target tracking policy to scale based on the mem_used_percent CloudWatch metric.

C.

Install and configure the AWS Systems Manager Agent (SSM Agent). Create a target tracking policy to scale based on the mem_used_percent Amazon CloudWatch metric.

D.

Install and configure the Amazon CloudWatch agent. Create a scheduled scaling policy to scale based on the memory usage trend.

Question 76

A company runs its workloads on Amazon Elastic Container Service (Amazon ECS). The container images that the ECS task definition uses need to be scanned for Common Vulnerabilities and Exposures (CVEs). New container images that are created also need to be scanned.

Which solution will meet these requirements with the FEWEST changes to the workloads?

Options:

A.

Use Amazon Elastic Container Registry (Amazon ECR) as a private image repository to store the container images. Specify scan on push filters for the ECR basic scan.

B.

Store the container images in an Amazon S3 bucket. Use Amazon Macie to scan the images. Use an S3 Event Notification to initiate a Made scan for every event with an s3:ObjeclCreated:Put event type

C.

Deploy the workloads to Amazon Elastic Kubernetes Service (Amazon EKS). Use Amazon Elastic Container Registry (Amazon ECR) as a private image repository. Specify scan on push filters for the ECR enhanced scan.

D.

Store the container images in an Amazon S3 bucket that has versioning enabled. Configure an S3 Event Notification for s3:ObjectCrealed:* events to invoke an AWS Lambda function. Configure the Lambda function to initiate an Amazon Inspector scan.
