Question #406 / 1019

A solutions architect is designing a two-tiered architecture that includes a public subnet and a database subnet. The web servers in the public subnet must be accessible from the internet on port 80. The Amazon RDS for PostgreSQL DB instance in the database subnet must be reachable only by the web servers on port 5432.

Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)

A

Create a network ACL for the public subnet. Add a rule to deny outbound traffic to 0.0.0.0/0 on port 5432.

B

Create a security group for the DB instance. Add a rule to allow traffic from the public subnet CIDR block on port 5432.

C

Create a security group for the web servers in the public subnet. Add a rule to allow traffic from 0.0.0.0/0 on port 80.

D

Create a security group for the DB instance. Add a rule to allow traffic from the web servers\u2019 security group on port 5432.

E

Create a security group for the DB instance. Add a rule to deny all traffic except traffic from the web servers\u2019 security group on port 5432.

Question #603 / 1019

A company is designing a serverless architecture on AWS to handle high-volume, real-time processing of diverse data types including application logs, image files, and sensor telemetry stored in Amazon S3. The solution must process each data item independently with maximum parallelism and scalability. Which approach provides the MOST scalable and efficient processing?

A

Use the AWS Step Functions Map state in Inline mode to process each item sequentially within a single execution.

B

Use the AWS Step Functions Map state in Distributed mode to process each item in a separate execution for maximum scalability.

C

Use AWS Glue to dynamically scale Apache Spark workers for parallel data processing.

D

Use multiple AWS Lambda functions invoked concurrently via Amazon S3 event notifications.

Sample Questions

Question #525 / 529

A company is hosting a web application on AWS using 20 Amazon EC2 On-Demand Instances distributed across two Availability Zones behind a Network Load Balancer (NLB). The application is stateless and operates continuously. Users report performance degradation during traffic spikes, where CPU utilization reaches 100%, though it remains at 10% during normal operation. The company seeks a cost-effective architectural solution to address the slowdowns.

Which option MOST cost-effectively resolves the performance issue?

A

Configure an Auto Scaling group attached to the NLB's target group. Set the minimum capacity to 20 and desired capacity to 35. Purchase Reserved Instances for 20 instances and use On-Demand for scaling.

B

Deploy a Spot Fleet with a request type of 'capacity-optimized.' Set TotalTargetCapacity to 20 and DefaultTargetCapacityType to On-Demand. Attach the fleet to the existing NLB.

C

Replace the NLB with an Application Load Balancer (ALB). Use a Spot Fleet with 'maintain' request type, TotalTargetCapacity of 20, and DefaultTargetCapacityType as Spot. Purchase Reserved Instances for 10 instances.

D

Implement an Auto Scaling group linked to the NLB's target group. Set minimum capacity to 4 and maximum to 35. Purchase Reserved Instances for 4 instances, scaling with On-Demand during peaks.

Question #25 / 529

A company operates an on-premises data processing system configured with full redundancy across 15 servers in their data center. The system executes scheduled jobs that run every 4 hours and daily, in addition to ad-hoc user requests. Scheduled jobs require between 30 minutes and 3 hours to complete and must adhere to strict SLAs, accounting for 70% of system usage. User jobs typically finish within 10 minutes and can tolerate delays during system issues, making up the remaining 30% of usage. During outages, scheduled jobs must still meet their SLAs, while user jobs can be postponed.

The company aims to migrate this system to Amazon EC2 instances, adopting a consumption-based pricing model to minimize costs without long-term commitments. The solution must ensure high availability and uphold the SLAs for scheduled jobs.

Which solution MOST cost-effectively meets these requirements?

A

Distribute the 15 instances across three Availability Zones. In each zone, run three On-Demand Instances with Capacity Reservations and two Spot Instances.

B

Distribute the 15 instances across two Availability Zones. Run five On-Demand Instances with Capacity Reservations in each zone, and five Spot Instances in a third zone.

C

Distribute the 15 instances across three Availability Zones. In each zone, run four On-Demand Instances with Capacity Reservations and one Spot Instance.

D

Distribute the 15 instances across three Availability Zones. Use Savings Plans for six On-Demand Instances spread equally across zones, and deploy the remaining nine as Spot Instances.

Sample Questions

Question #368 / 557

A developer built a distributed application using microservices deployed on Amazon EC2 instances. Due to high traffic, correlating logs across microservices for individual transactions has become challenging. The developer needs to trace request paths to identify bottlenecks.

Which two actions should the developer take to address this? (Choose two.)

A

Install the AWS X-Ray daemon on an EC2 instance, ensuring UDP port 2000 is open for outbound traffic.

B

Create a VPC endpoint for X-Ray to allow TCP traffic on port 2000 to the AWS managed daemon.

C

Integrate AWS CloudWatch Logs with X-Ray to automatically correlate log entries.

D

Incorporate the AWS X-Ray SDK into each microservice to trace and segment requests.

E

Configure Amazon Kinesis Data Firehose to stream metrics to X-Ray for analysis.

Question #192 / 557

A company is migrating its on-premises PostgreSQL database to AWS and requires automated rotation of database credentials every 30 days without additional programming. Which setup fulfills these requirements?

A

Use Amazon Aurora PostgreSQL. Store credentials in AWS Systems Manager Parameter Store with rotation enabled.

B

Use Amazon Aurora PostgreSQL. Store credentials in AWS Secrets Manager with rotation enabled.

C

Use Amazon DynamoDB. Store credentials in AWS Secrets Manager with rotation enabled.

D

Use Amazon DynamoDB. Store credentials in AWS Systems Manager Parameter Store with rotation enabled.
