Question #91 / 1019

A company operates applications on Amazon EC2 instances within a VPC. One application requires access to the Amazon DynamoDB API to store and retrieve data. The company's security policies mandate that no application traffic can traverse the public internet. Which solution will satisfy these requirements?

A

Create a DynamoDB table in a private subnet within the VPC.

B

Configure a DynamoDB gateway endpoint for the VPC.

C

Ensure the DynamoDB table is in the same AWS Region as the EC2 instances.

D

Deploy a NAT gateway in the same subnet as the EC2 instances.

Question #166 / 1019

A company is launching a new product and needs to host promotional static HTML pages that anticipate millions of global views. The files are stored in an Amazon S3 bucket. A solutions architect must design a cost-effective and scalable solution for optimal content delivery. What should the architect implement?

A

Generate presigned URLs for each file access.

B

Enable cross-Region replication to duplicate the bucket across all Regions.

C

Configure the geoproximity routing feature in Amazon Route 53.

D

Sample Questions

Question #479 / 529

A company operates an event registration application on Amazon Elastic Container Service (Amazon ECS) with Amazon CloudFront as the origin. Users with a valid encrypted JSON Web Token (JWT) can access the registration interface, while others are redirected to a waiting room. During peak traffic, the waiting room's load is causing availability issues for the registration system, impacting transaction reliability.

Which solution will MOST improve the reliability of registration transactions during high load?

A

Create a separate ECS service for the waiting room with independent scaling. Configure the registration service to inspect JWTs and redirect users to the waiting room when necessary.

B

Migrate the application to Amazon Elastic Kubernetes Service (Amazon EKS). Split the waiting room into a separate pod and deploy the registration service as a StatefulSet. Configure the registration pod to forward requests to the waiting room pod based on JWT validation.

C

Create a separate ECS service for the waiting room with independent scaling. Implement a CloudFront function to inspect the JWT and route requests directly to the registration service or waiting room service.

D

Use Amazon API Gateway with a JWT authorizer to validate tokens and route requests to the appropriate ECS service. Deploy separate services for registration and the waiting room with independent scaling configurations.

Question #443 / 529

An air quality monitoring network has deployed over 10,000 environmental sensors that continuously transmit air quality metrics. Each update is under 1 MB in size. The network uses on-premises application servers to process incoming data, convert it into a structured format, and store it in an on-premises relational database. Data analysts use SQL queries to analyze the data. Maintenance tasks on the servers, such as updates and patches, cause downtime and data loss during peak loads. The organization wants to minimize operational overhead, reduce maintenance efforts, and ensure high availability. A solutions architect proposes using AWS IoT Core for data ingestion. What additional solution should the architect recommend?

A

Route sensor data to Amazon Kinesis Data Firehose. Use an AWS Lambda function to process the data into .csv format and insert it into an Amazon Aurora MySQL DB instance. Instruct analysts to query the database directly.

B

Route sensor data to Amazon Kinesis Data Firehose. Use an AWS Lambda function to process the data into Apache Parquet format and store it in an Amazon S3 bucket. Instruct analysts to query the data using Amazon Athena.

C

Route sensor data to an Amazon Managed Service for Apache Flink application to convert it into .csv format and store it in an Amazon S3 bucket. Import the data into an Amazon Aurora MySQL DB instance. Instruct analysts to query the database directly.

D

Route sensor data to an Amazon Managed Service for Apache Flink application to convert it into Apache Parquet format and store it in an Amazon S3 bucket. Instruct analysts to query the data using Amazon Athena.

Sample Questions

Question #405 / 557

A developer uses an AWS Lambda function in an application to process users' uploaded videos for transcoding. The developer needs to update the Lambda function code and test the changes by distributing traffic between the old and new versions.

Which combination of steps will meet these requirements? (Choose two.)

A

Publish a version of the original Lambda function. Modify the Lambda code. Publish a new version of the Lambda function.

B

Use AWS CodeDeploy to detect updates to the Lambda function. Configure CodeDeploy to gradually shift traffic from the original version to the new version.

C

Update the original Lambda function to enable a function URL. Modify the Lambda code. Publish another function URL for the updated code.

D

Create an alias pointing to the original Lambda version. Configure the alias as a weighted alias including the new version. Split traffic between versions.

E

Create an alias pointing to the original function URL. Configure the alias to include the new function URL and divide traffic between them.

Question #402 / 557

A company uses AWS CloudFormation templates to manage infrastructure for a public-facing application across development, staging, and production environments. To handle increased traffic, a developer needs to upgrade the EC2 instance type to a larger instance in the staging environment.

The developer updates the CloudFormation stack with the new instance type. After the update, the stack enters the UPDATEROLLBACKFAILED state.

What is the most likely cause of this issue?

A

The new EC2 instance type specified is not available in the current AWS Region

B

The EC2 instance was manually terminated and re-launched with a different instance type outside of CloudFormation

C

The CloudFormation template contains an incorrect AMI ID for the new instance type

D

The developer lacks the necessary IAM permissions to modify the EC2 instance type
