Question #501 / 1019

A company is collecting log data from IoT devices every 30 seconds and needs to process this data in real time to detect anomalies. After processing, the data must be stored in an Amazon S3 data lake. Which solution offers the MOST operational efficiency?

A

Use Amazon Kinesis Data Streams to ingest data. Use AWS Lambda to process the data in real time.

B

Use AWS Glue to ingest data. Use Amazon Kinesis Data Analytics to process the data in real time.

C

Use Amazon Kinesis Data Firehose to ingest data. Use Amazon Kinesis Data Analytics to process the data in real time.

D

Use Amazon API Gateway to ingest data. Use AWS Lambda to process the data in real time.

Question #434 / 1019

A company operates a web application on AWS using Amazon EC2 instances behind an Application Load Balancer within an Auto Scaling group. The application stores data in an Amazon DynamoDB table. To ensure business continuity, the company needs to implement a disaster recovery plan that allows rapid failover to another AWS Region with minimal downtime.

Which approach should a solutions architect recommend to meet these requirements with the LEAST downtime?

A

Set up an Auto Scaling group and Application Load Balancer in the secondary Region. Replicate the DynamoDB table using global tables. Use Amazon Route 53 with health checks to route traffic to the secondary Region's load balancer during failover.

B

Use AWS CloudFormation to define infrastructure templates for EC2, ALB, and DynamoDB in the secondary Region. Configure Route 53 failover to direct traffic to the secondary Region upon manual intervention.

C

Deploy an Auto Scaling group and ALB in the secondary Region. Configure DynamoDB cross-region backups with scheduled restore processes. Implement a CloudWatch alarm to trigger a Lambda function that updates Route 53 to the secondary Region.

D

Create a standby environment in the secondary Region using EC2 instances and ALB. Use DynamoDB on-demand backups for data recovery. Set up Route 53 with weighted routing to gradually shift traffic to the secondary Region.

Sample Questions

Question #522 / 529

A company in the United States (US) has acquired a company in Asia. Both companies use the AWS Cloud. The US company hosts a distributed application across three VPCs in the us-west-2 Region. The application must access resources in two VPCs in the ap-northeast-1 Region but must not access any other VPCs. The VPCs in both Regions have non-overlapping CIDR ranges, and all accounts are consolidated under one organization in AWS Organizations. Which solution will meet these requirements MOST cost-effectively?

A

Create a transit gateway in ap-northeast-1. Attach the VPCs in us-west-2 and the two VPCs in ap-northeast-1 to the transit gateway. Configure route tables to direct traffic through the transit gateway.

B

Deploy a transit gateway in each Region. Attach the relevant VPCs to their regional transit gateway. Establish a peering connection between the transit gateways and update route tables to route traffic through the gateways.

C

Create a full mesh of VPC peering connections between all VPCs in both Regions. Update route tables to route traffic through the peering connections.

D

Create separate VPC peering connections from each of the three VPCs in us-west-2 to both VPCs in ap-northeast-1. Update route tables in all connected VPCs to route traffic through the peering connections.

Question #331 / 529

A company is migrating a logging application to the AWS Cloud. The application runs in an on-premises data center and writes thousands of log files into a mounted NFS file system daily. After migration, the company will host the application on an Amazon EC2 instance with a mounted Amazon Elastic File System (Amazon EFS) file system. The company uses AWS Direct Connect. Before the migration cutover, a solutions architect must create a process to replicate newly generated on-premises log files to the EFS file system. What is the MOST operationally efficient way to replicate the logs?

A

Configure a periodic process to run the aws s3 sync command from the on-premises file system to Amazon S3. Use an AWS Lambda function triggered by S3 event notifications to copy the logs from Amazon S3 to the EFS file system.

B

Deploy an AWS Storage Gateway file gateway with an NFS mount point. Mount the file gateway file system on the on-premises server. Schedule a process to periodically copy the logs to the mount point.

C

Deploy an AWS DataSync agent to an on-premises server with access to the NFS file system. Transfer data over the Direct Connect connection to an S3 bucket using a public VIF. Use an AWS Lambda function triggered by S3 events to copy the logs from Amazon S3 to the EFS file system.

D

Deploy an AWS DataSync agent to an on-premises server with access to the NFS file system. Transfer data over the Direct Connect connection to an AWS PrivateLink interface VPC endpoint for Amazon EFS using a private VIF. Configure a DataSync scheduled task to replicate the logs to the EFS file system every 24 hours.

Question #379 / 557

A developer is monitoring an AWS Lambda function configured to process real-time data. The developer has created a custom Amazon CloudWatch metric with a data granularity of 1 second to track the function's execution duration. If the function exceeds a specified threshold, the developer needs to receive an Amazon SNS notification within 20 seconds. What should the developer do to achieve this?

A

Create a high-resolution CloudWatch alarm.

B

Use Amazon CloudWatch Logs subscriptions.

C

Configure a standard-resolution CloudWatch alarm.

D

B

Use AWS CodeDeploy to execute test scripts during deployment. Define the report parameters in the appspec.yml file.

C

Install a custom testing framework on an Amazon EC2 instance managed by AWS Systems Manager and run tests via SSM documents.

D

Configure AWS CodeCommit to store test scripts and generate reports using Git hooks.
