Question # 121

A company generates approximately 20 GB of data multiple times each day. The company uses AWS DataSync to copy all data from on-premises storage to Amazon S3 every 6 hours for further processing. The analytics team wants to modify the copy process to copy only data relevant to the analytics team and ignore the rest of the data. The team wants to copy data as soon as possible and receive a notification when the copy process is finished. Which combination of steps will meet these requirements MOST cost-effectively? (Select THREE.)

Modify the data generation process on-premises to create a manifest file at the end of the copy process with the names of the objects to be copied to Amazon S3. Create a custom script to upload the manifest file to an S3 bucket.

Modify the data generation process on-premises to create a manifest file at the end of the copy process with the names of the objects to be copied to Amazon S3. Create an AWS Lambda function to load the manifest file data into an Amazon DynamoDB table.

Create an AWS Lambda function that Amazon EventBridge invokes when the manifest file is loaded into Amazon DynamoDB. Configure the Lambda function to copy the data from on-premises storage to the S3 bucket that uses the manifest file.

Create an AWS Lambda function that an S3 Event Notification invokes when the manifest file is uploaded. Configure the Lambda function to invoke the DataSync task by calling the StartTaskExecution API action with a manifest.

Create an Amazon Simple Notification Service (Amazon SNS) topic. Create an Amazon EventBridge rule to send an email notification to the SNS topic when the DataSync task execution status changes to SUCCESS or to ERROR.

Explanation:

Comprehensive and Detailed Step-by-Step Explanation:

To meet the requirements of copying only relevant data as soon as possible and receiving notifications upon completion, the following steps are recommended:

Generate a Manifest File (Option A):

Action:Modify the on-premises data generation process to create a manifest file at the end of each data generation cycle. This manifest should list the names of the objects that need to be copied to Amazon S3.

Implementation:Develop a custom script that runs after data generation. This script compiles the list of relevant data files into a manifest file and uploads it to a designated S3 bucket.

Justification:Using a manifest allows AWS DataSync to transfer only the specified files, reducing unnecessary data transfer and associated costs.

Automate DataSync Task Execution (Option D):

Action:Set up an S3 Event Notification to trigger an AWS Lambda function whenever a new manifest file is uploaded to the S3 bucket.

Implementation:Configure the Lambda function to invoke the DataSync task by calling the StartTaskExecution API action, specifying the manifest file. This ensures that only the files listed in the manifest are copied from on-premises storage to Amazon S3.

Justification:This automation ensures timely data transfer as soon as relevant data is available, minimizing delays and manual intervention.

docs.aws.amazon.com

Set Up Completion Notifications (Option E):

Action:Create an Amazon SNS topic to handle notifications. Then, establish an Amazon EventBridge rule that monitors the DataSync task execution status and sends an email notification to the SNS topic when the status changes to SUCCESS or ERROR.

Implementation:Configure EventBridge to capture state changes of the DataSync task. When a task completes successfully or encounters an error, EventBridge triggers a notification to the SNS topic, which then sends an email to the subscribed recipients.

Justification:This setup provides immediate feedback on the data transfer process, allowing the analytics team to act promptly based on the success or failure of the data copy operation.

Question # 122

An ecommerce company is redesigning a product catalog system to handle millions of products and provide fast access to product information. The system needs to store structured product data such as product name, price, description, and category. The system also needs to store unstructured data such as high-resolution product videos and user manuals. The architecture must be highly available and must be able to handle sudden spikes in traffic during large-scale sales events.

Use an Amazon RDS Multi-AZ deployment to store product information. Store product videos and user manuals in Amazon S3.

Use Amazon DynamoDB to store product information. Store product videos and user manuals in Amazon S3.

Store all product information, including product videos and user manuals, in Amazon DynamoDB.

Deploy an Amazon DocumentDB (with MongoDB compatibility) cluster to store all product information, product videos, and user manuals.

Question # 123

A company deployed an application in two AWS Regions. If the application fails in one Region, traffic must fail over to the second Region. The failover must avoid stale DNS client caches, and the company requires one endpoint for both Regions.

Which solution meets these requirements?

Use a CloudFront distribution with multiple origins.

Use Route 53 weighted routing with equal weights.

Use AWS Global Accelerator and assign static anycast IPs to the application.

Use Route 53 IP-based routing to switch Regions.

Question # 124

A solutions architect needs to secure an Amazon API Gateway REST API. Users need to be able to log in to the API by using common external social identity providers (IdPs). The social IdPs must use standard authentication protocols such as SAML or OpenID Connect (OIDC). The solutions architect needs to protect the API against attempts to exploit application vulnerabilities.

Which combination of steps will meet these security requirements? (Select TWO.)

Create an AWS WAF web ACL that is associated with the REST API. Add the appropriate managed rules to the ACL.

Subscribe to AWS Shield Advanced. Enable DDoS protection. Associate Shield Advanced with the REST API.

Create an Amazon Cognito user pool with a federation to the social IdPs. Integrate the user pool with the REST API.

Create an API key in API Gateway. Associate the API key with the REST API.

Create an IP address filter in AWS WAF that allows only the social IdPs. Associate the filter with the web ACL and the API.

Question # 125

A company runs a production application on a fleet of Amazon EC2 instances. The application reads messages from an Amazon Simple Queue Service (Amazon SQS) queue and processes the messages in parallel. The message volume is unpredictable and highly variable.

The company must ensure that the application continually processes messages without any downtime.

Which solution will meet these requirements MOST cost-effectively?

Use only Spot Instances to handle the maximum capacity required.

Use only Reserved Instances to handle the maximum capacity required.

Use Reserved Instances to handle the baseline capacity. Use Spot Instances to provide additional capacity when required.

Use Reserved Instances in an EC2 Auto Scaling group to handle the minimum capacity. Configure an auto scaling policy that is based on the SQS queue backlog.

Question # 126

A company uses Amazon Elastic Container Service (Amazon ECS) to run workloads that belong to service teams. Each service team uses an owner tag to specify the ECS containers that the team owns. The company wants to generate an AWS Cost Explorer report that shows how much each service team spends on ECS containers on a monthly basis.

Which combination of steps will meet these requirements in the MOST operationally efficient way? (Select TWO.)

Create a custom report in Cost Explorer. Apply a filter for Amazon ECS.

Create a custom report in Cost Explorer. Apply a filter for the owner resource tag.

Set up AWS Compute Optimizer. Review the rightsizing recommendations.

Activate the owner tag as a cost allocation tag. Group the Cost Explorer report by linked account.

Activate the owner tag as a cost allocation tag. Group the Cost Explorer report by the owner cost allocation tag.

Question # 127

An ecommerce company runs Its application on AWS. The application uses an Amazon Aurora PostgreSQL cluster in Multi-AZ mode for the underlying database. During a recent promotionalcampaign, the application experienced heavy read load and write load. Users experienced timeout issues when they attempted to access the application.
