Question #156 / 1019

A company receives batch data from multiple relational databases and real-time streaming data from IoT devices. The company requires a solution to unify all data into a central repository for analytics. The solution must process incoming data, store it in designated Amazon S3 buckets, and support ad-hoc queries for integration with business intelligence (BI) tools to visualize key performance indicators (KPIs) with minimal operational effort. Which combination of steps meets these requirements with the LEAST operational overhead? (Choose two.)

A

Use Amazon Athena for ad-hoc queries. Use Amazon QuickSight to create KPI dashboards.

B

Deploy Amazon Kinesis Data Analytics to process streaming data. Use Amazon Redshift Spectrum for querying data directly in S3.

C

Develop custom AWS Lambda functions to transform and load data into Amazon RDS instances.

D

Use AWS Glue ETL jobs to process batch data into Parquet format. Use Amazon Kinesis Data Firehose to ingest streaming data into Amazon S3.

E

Configure AWS Glue crawlers to catalog data sources. Use AWS Lake Formation to automate data lake setup and enforce access controls.

Question #413 / 1019

An online retail platform operates a three-tier architecture on AWS, with web servers on EC2, an application tier, and a database tier. During seasonal sales, the application tier becomes overloaded, leading to delayed order confirmation emails and slower response times for user requests. The company wants to decouple email processing to improve application performance and minimize administrative efforts.

What should a solutions architect recommend to address these requirements?

A

Provision additional EC2 instances in the application tier specifically for email processing.

B

Integrate Amazon Simple Email Service (SES) into the application tier to handle email delivery.

C

Use Amazon Simple Notification Service (SNS) to publish email notifications and subscribe relevant services.

D

Implement an Auto Scaling group for the application tier to dynamically adjust capacity based on email processing load.

Sample Questions

Question #491 / 529

A company is developing a latency-sensitive application. Part of the application includes several AWS Lambda functions that need to initialize as quickly as possible. The Lambda functions are written in .NET and contain initialization code outside the handlers to load configuration files, initialize dependencies, and establish database connections.

Which solution will meet the startup performance requirement MOST cost-effectively?

A

Move all the initialization code to the handlers for each Lambda function. Activate Lambda SnapStart for each Lambda function. Configure SnapStart to reference the unpublished $LATEST version of each Lambda function.

B

Publish a version of each Lambda function. Create an alias for each Lambda function pointing to the published version. Configure provisioned concurrency for each alias and enable SnapStart for the unpublished $LATEST versions.

C

Publish a version of each Lambda function. Enable SnapStart for the published versions. Configure provisioned concurrency for the $LATEST versions and move the database connection logic into the handlers.

D

Update the Lambda functions to include a pre-snapshot hook. Move the database connection initialization into the handlers. Publish a version of each Lambda function. Activate Lambda SnapStart for the published versions of the Lambda functions.

Question #1 / 529

A company needs to design a hybrid DNS solution using an Amazon Route 53 private hosted zone for the domain cloud.newdomain.com to support resources across multiple VPCs. The solution must meet the following requirements:

- On-premises systems must resolve and connect to cloud.newdomain.com.
- All VPCs must resolve cloud.newdomain.com.

The company uses AWS Direct Connect and AWS Transit Gateway to link its on-premises network to AWS.

Which architecture ensures the HIGHEST performance while fulfilling these requirements?

A

Associate the private hosted zone with all VPCs. Deploy a Route 53 inbound resolver in the shared services VPC. Connect all VPCs to the transit gateway and configure on-premises DNS to forward cloud.newdomain.com requests to the inbound resolver.

B

Associate the private hosted zone with all VPCs. Set up an EC2-based conditional forwarder in the shared services VPC. Attach all VPCs to the transit gateway and direct on-premises DNS to forward cloud.newdomain.com queries to the conditional forwarder.

C

Associate the private hosted zone with the shared services VPC. Create a Route 53 outbound resolver in the shared services VPC. Link all VPCs to the transit gateway and configure on-premises DNS to forward cloud.newdomain.com requests to the outbound resolver.

D

Associate the private hosted zone with the shared services VPC. Deploy a Route 53 inbound resolver in the shared services VPC. Connect the shared services VPC to the transit gateway and set up on-premises DNS to forward cloud.newdomain.com queries to the inbound resolver.

Question #413 / 557

A developer is using multiple AWS Lambda functions that require access to dynamic configuration data stored as an 8 KB JSON file in AWS AppConfig. The configuration must be updated frequently without requiring redeployment of the Lambda functions. The developer needs a solution that minimizes development effort while ensuring the Lambda functions can retrieve the latest configuration data at runtime.

What should the developer do to meet these requirements?

A

Migrate the JSON file from AWS AppConfig to AWS Systems Manager Parameter Store. Retrieve the parameter value at runtime using the AWS SDK.

B

Configure the AWS AppConfig Lambda extension. Access the configuration data by querying the extension via a local HTTP endpoint.

C

Use the AWS SDK to directly call AWS AppConfig APIs within the Lambda functions. Cache the configuration data to reduce API calls.

D

Embed the configuration file in the Lambda layer. Read the file from the layer's file system during execution.
