Question #11 / 1019

A company operates an application on Amazon EC2 instances that connects to an Amazon RDS MySQL database. The database credentials are currently stored in a plaintext file on each EC2 instance. The company aims to reduce the operational overhead associated with managing these credentials securely.

What should a solutions architect recommend to achieve this goal?

A

Use AWS Secrets Manager and enable automatic rotation for the credentials.

B

Use AWS Systems Manager Parameter Store and implement a custom rotation process.

C

Store the credentials in an Amazon S3 bucket encrypted with AWS KMS. Update the application to retrieve credentials from S3.

D

Encrypt the credentials file using AWS KMS and store it on an encrypted EBS volume attached to each EC2 instance.

Question #720 / 1019

A media company runs its video processing application on AWS. The application processes each video in about 30 minutes. The application is built as a monolith that runs on a single Amazon EC2 instance. The application requires frequent updates to its tightly coupled modules. The application becomes complex to maintain as the company adds new features. Each time the company patches a software module, the application experiences downtime. Video processing must restart from the beginning after any interruptions. The company wants to redesign the application to be flexible, scalable, and allow gradual improvements with minimal downtime. Which solution meets these requirements?

A

Run the application on AWS Lambda as a single function with maximum provisioned concurrency.

B

Run the application on Amazon EC2 Spot Instances as microservices with a Spot Fleet default allocation strategy.

C

Run the application on Amazon Elastic Container Service (Amazon ECS) as microservices with service auto scaling.

D

Run the application on AWS Elastic Beanstalk as a single application environment with an all-at-once deployment strategy.

Sample Questions

Question #310 / 529

A company wants to use Amazon S3 to archive logs from its on-premises application servers. The application servers use an NFS-based file system, and the company requires the new solution to maintain NFS compatibility. The company wants to transition logs to archival storage after 7 days. If archived logs are needed for compliance audits, the company can tolerate retrieval times of several days. Which solution meets these requirements MOST cost-effectively?

A

Deploy an AWS Storage Gateway file gateway associated with an S3 bucket. Transfer logs from the on-premises servers to the file gateway. Create an S3 Lifecycle rule to transition logs to S3 Standard-Infrequent Access (S3 Standard-IA) after 7 days.

B

Deploy an AWS Storage Gateway volume gateway associated with an S3 bucket. Transfer logs from the on-premises servers to the volume gateway. Create an S3 Lifecycle rule to transition logs to S3 Glacier Deep Archive after 7 days.

C

Deploy an AWS Storage Gateway tape gateway associated with an S3 bucket. Transfer logs from the on-premises servers to the tape gateway. Create an S3 Lifecycle rule to transition logs to S3 Glacier Flexible Retrieval after 7 days.

D

Deploy an AWS Storage Gateway file gateway associated with an S3 bucket. Transfer logs from the on-premises servers to the file gateway. Create an S3 Lifecycle rule to transition logs to S3 Glacier Deep Archive after 7 days.

Question #345 / 529

A European company with headquarters in Frankfurt is deploying a new web application running on Amazon EC2 in the eu-west-1 Region. The application must dynamically scale to handle traffic spikes and ensure high availability. Additionally, it requires disaster recovery capabilities in an active-passive configuration with the eu-central-1 Region.

Which steps should a solutions architect take after creating a VPC in the eu-west-1 Region?

A

Create a VPC in the eu-central-1 Region. Establish inter-Region VPC peering between the two VPCs. Deploy an Application Load Balancer (ALB) across multiple Availability Zones (AZs) in the eu-west-1 VPC. Deploy EC2 instances across multiple AZs in both Regions as part of a single Auto Scaling group spanning both VPCs, linked to the ALB.

B

Deploy an Application Load Balancer (ALB) spanning multiple AZs in the eu-west-1 VPC. Configure EC2 instances across multiple AZs using an Auto Scaling group served by the ALB. Replicate the same architecture in the eu-central-1 Region. Set up an Amazon Route 53 record with a failover routing policy and health checks to route traffic between the two Regions.

C

Create a VPC in the eu-central-1 Region. Use inter-Region VPC peering to connect the VPCs. Deploy a global ALB across both Regions. Configure EC2 instances in each Region as part of separate Auto Scaling groups linked to the ALB. Create a Route 53 alias record pointing to the ALB.

D

Deploy an ALB spanning multiple AZs in the eu-west-1 VPC. Configure EC2 instances using an Auto Scaling group in eu-west-1. Replicate the solution in eu-central-1. Create separate Route 53 records for each Region with latency-based routing and health checks to distribute traffic.

Sample Questions

Question #277 / 557

A developer is building a mobile application that requires users to authenticate via third-party social platforms. The application uses AWS Lambda functions behind an Amazon API Gateway REST API to handle backend logic. The solution must ensure secure authentication, minimize operational overhead, and avoid storing or managing user credentials directly. Which approach meets these requirements?

A

Implement Amazon Cognito user pools with federated social identity providers and configure IAM roles using an identity pool.

B

Store user credentials in an Amazon DynamoDB table and validate logins using IAM policies attached to the table.

C

Create individual IAM users for each application user and assign IAM policies to grant resource access.

D

Use an Amazon RDS PostgreSQL database to store user credentials and manage permissions via database roles.

Question #448 / 557

A developer is designing a serverless application on AWS that uses an AWS Lambda function to process data streams from Amazon Kinesis Data Streams. The Lambda function is experiencing high latency during peak traffic periods due to insufficient CPU resources to process the incoming records efficiently. The developer needs to optimize the Lambda function's configuration to reduce latency without altering the core functionality. Which solution will address this issue?

A

Increase the number of virtual CPU (vCPU) cores allocated to the Lambda function.

B

Increase the memory allocation for the Lambda function to scale its CPU proportionally.

C

Increase the size of the Lambda function's ephemeral storage to improve data caching.

D

Increase the Lambda function's concurrency limit to handle more simultaneous requests.
