Question #979 / 1019

A company is developing a social media platform that utilizes a relational database to manage user interactions and post metadata. The platform is expected to experience highly variable traffic, predominantly read-heavy with sporadic write operations during peak events. The company prioritizes cost efficiency and seeks a managed AWS database solution that dynamically scales to meet demand without manual intervention.

Which option provides the MOST cost-effective solution while satisfying the performance requirements?

A

Deploy the database on Amazon RDS using Provisioned IOPS SSD storage to maintain consistent performance for both read and write operations.

B

Deploy the database on Amazon Aurora Serverless, which automatically scales the database's capacity up or down based on the application's needs.

C

Deploy the database on Amazon DynamoDB with on-demand capacity mode to adjust throughput automatically as workload demands change.

D

Deploy the database on Amazon RDS with General Purpose SSD storage and utilize read replicas to handle increased read traffic.

Question #342 / 1019

A media streaming company runs nightly video transcoding jobs on Amazon EC2 instances within an Auto Scaling group. The transcoding workload varies, but the baseline CPU utilization observed during each job is consistently 70%. The company must ensure capacity is provisioned 45 minutes before jobs begin. Currently, engineers manually adjust the Auto Scaling group's desired capacity, but the company lacks resources to analyze historical capacity trends. They require an automated solution with minimal operational overhead. Which approach best meets these requirements?

A

Implement a dynamic scaling policy targeting 70% CPU utilization. Configure the policy to adjust the Auto Scaling group's capacity based on real-time metric thresholds.

B

Set up a scheduled scaling policy with fixed desired, minimum, and maximum capacity values. Configure the recurrence to daily and set the start time 45 minutes before the transcoding jobs begin.

C

Deploy a predictive scaling policy using historical CPU utilization data. Configure the policy to forecast demand and launch instances 45 minutes prior to job execution, targeting 70% CPU utilization.

D

Use Amazon EventBridge to trigger an AWS Lambda function when CPU utilization reaches 70%. Configure the Lambda function to dynamically increase the Auto Scaling group's desired and maximum capacity by 25%.

Sample Questions

Question #474 / 529

A logistics company wants to improve its application architecture. The company's applications manage shipment tracking, handle inventory updates, and generate logistics reports. The applications store logistics data in a PostgreSQL database and a Snowflake data warehouse. All the applications and databases are hosted on Amazon EC2 instances.

Each application consists of several components that handle different parts of the logistics process. These components use incoming data from different sources. A separate ETL job runs every week and copies data from each application to the data warehouse.

A solutions architect must redesign the architecture into an event-driven solution that uses serverless services. The solution must provide updated analytics in near real time.

Which solution will meet these requirements?

A

Migrate the individual applications as microservices to Amazon Elastic Container Service (Amazon ECS) containers that use AWS Fargate. Keep the logistics PostgreSQL database on Amazon EC2. Move the data warehouse to Amazon Neptune. Use Amazon Simple Queue Service (Amazon SQS) to send all the incoming data to the microservices and the data warehouse.

B

Create an Auto Scaling group for each application. Specify the necessary number of EC2 instances in each Auto Scaling group. Migrate the logistics PostgreSQL database and the data warehouse to Amazon Aurora PostgreSQL. Use Amazon Simple Notification Service (Amazon SNS) to send all the incoming data to the correct EC2 instances and the data warehouse.

C

Migrate the individual applications as microservices to Amazon Elastic Kubernetes Service (Amazon EKS) containers that use AWS Fargate. Migrate the logistics PostgreSQL database to Amazon Aurora Serverless PostgreSQL. Migrate the data warehouse to Amazon Redshift Serverless. Use Amazon EventBridge to send all the incoming data to the microservices and the data warehouse.

D

Migrate the individual applications as microservices to Amazon AppStream 2.0. Migrate the logistics PostgreSQL database to Amazon Aurora PostgreSQL. Migrate the data warehouse to Amazon Redshift Serverless. Use AWS IoT Core to send all the incoming data to the microservices and the data warehouse.

Question #248 / 529

An online learning platform uses Amazon API Gateway for its REST API, which is integrated with AWS Lambda. The API experiences weekly surges in excessive requests from around 800 different IP addresses that rotate each week, causing increased latency and timeouts. A solutions architect needs to mitigate this issue with the MOST operational efficiency. Which solution meets these requirements?

A

Use AWS Firewall Manager to create a security group policy to deny access from the IP addresses.

B

Create an AWS WAF web ACL with a rate-based rule, set the rule action to Block, and associate the web ACL with the API Gateway.

C

Use AWS Firewall Manager to create a security group policy to allow access only to specific CIDR ranges.

D

Create an AWS WAF web ACL with an IP set match rule, set the rule action to Block, and associate the web ACL with the API Gateway.

Sample Questions

Question #220 / 557

A developer is encountering HTTP 400: ProvisionedThroughputExceededException errors intermittently when performing write operations on an Amazon DynamoDB table. When the error occurs, the operation fails and no data is written.

What best practice should first be implemented to resolve this issue?

A

Contact AWS Support to request a provisioned throughput increase.

B

Use the AWS SDK to execute the write operations.

C

Analyze the application and reduce the number of write operations.

D

Retry the operation with exponential backoff.

Question #95 / 557

A developer is using a Border Gateway Protocol (BGP)-based AWS VPN connection to establish connectivity between an on-premises network and Amazon EC2 instances in their VPC. The developer can successfully access an EC2 instance in subnet X but cannot connect to an EC2 instance in subnet Y, which resides in the same VPC and Availability Zone. Both subnets have valid route table entries pointing to the VPN gateway.

Which logging service should the developer use to determine whether traffic from the on-premises network is being routed to subnet Y?

A

VPN connection logs

B

BGP session logs

C

VPC Flow Logs

D

AWS CloudTrail logs
