Question #186 / 1019

A company is deploying a Windows-based application on AWS that requires a shared file system accessible by multiple Amazon EC2 Windows instances distributed across multiple Availability Zones. What should a solutions architect implement to satisfy this requirement?

A

Deploy AWS Storage Gateway in file gateway mode. Configure the gateway to provide SMB access and mount the shared file system on each Windows instance.

B

Configure Amazon FSx for Windows File Server with Multi-AZ deployment. Mount the Amazon FSx file system to each Windows instance using the SMB protocol.

C

Create an Amazon Elastic File System (EFS) and enable the EFS mount helper. Mount the file system to each Windows instance using the NFS protocol.

D

Provision an Amazon Elastic Block Store (EBS) volume in each Availability Zone. Attach the respective volume to instances in each AZ and configure a distributed file system.

Question #830 / 1019

A social media platform manages 8 TB of datasets, including 2 million user profiles and 20 million follower relationships. The relationships are many-to-many. The platform requires a highly performant method to identify mutual followers up to six degrees of separation. Which solution best meets these requirements?

A

Store the datasets in Amazon S3 and use Amazon Redshift to execute complex JOIN queries for finding connections.

B

Utilize Amazon Neptune to model the data as a graph with nodes and edges, then traverse the graph to find mutual followers.

C

Store the datasets in Amazon DynamoDB tables and use batch operations to recursively search for connections.

D

Use Amazon OpenSearch Service to index the datasets and perform search queries to discover connections.

Sample Questions

Question #359 / 529

A company stores approximately 2 million .csv files on-premises across multiple VMs, with an initial dataset of 500 TB growing by 2 TB weekly. The company requires automated daily backups to AWS Cloud, with the ability to apply custom filters to back up only specific subsets of data from predefined source directories. They have an existing AWS Direct Connect connection. Which solution meets these requirements with the LEAST operational overhead?

A

Create an AWS Backup plan targeting Amazon S3 Glacier Flexible Retrieval. Configure a lifecycle policy to transition backups to Amazon S3 Standard-Infrequent Access after 30 days.

B

Deploy an AWS Storage Gateway file gateway on-premises. Use a scheduled AWS Lambda function to trigger backups to Amazon S3 daily via the file gateway interface.

C

Install an AWS DataSync agent on the on-premises VMs. Configure a DataSync task with custom filters to replicate designated data to Amazon S3 daily.

D

Use AWS Snowcone devices for the initial data transfer. Schedule AWS CLI commands to sync incremental changes to Amazon S3 daily using cron jobs.

Question #269 / 529

A company wants to optimize AWS data-transfer costs and compute costs across developer accounts within the company's organization in AWS Organizations. Developers can configure VPCs and launch Amazon EC2 instances in a single AWS Region.

The EC2 instances upload approximately 500 GB of data each day to Amazon DynamoDB.

The developer activity leads to excessive monthly data-transfer charges and NAT gateway processing costs between EC2 instances and DynamoDB, along with high compute costs. The company wants to proactively enforce approved architectural patterns for any EC2 instance and VPC infrastructure that developers deploy within the AWS accounts. The company does not want this enforcement to negatively affect the speed at which the developers can perform their tasks.

Which solution will meet these requirements MOST cost-effectively?

A

Create SCPs to prevent developers from launching unapproved EC2 instance types. Provide the developers with an AWS CloudFormation template to deploy an approved VPC configuration with DynamoDB interface endpoints. Scope the developers' IAM permissions so that the developers can launch VPC resources only with CloudFormation.

B

Create a daily forecasted budget with AWS Budgets to monitor EC2 compute costs and DynamoDB data-transfer costs across the developer accounts. When the forecasted cost is 75% of the actual budget cost, send an alert to the developer teams. If the actual budget cost is 100%, create a budget action to terminate the developers' EC2 instances and VPC infrastructure.

C

Create an AWS Service Catalog portfolio that users can use to create an approved VPC configuration with DynamoDB gateway endpoints and approved EC2 instances. Share the portfolio with the developer accounts. Configure an AWS Service Catalog launch constraint to use an approved IAM role. Scope the developers' IAM permissions to allow access only to AWS Service Catalog.

D

Create and deploy AWS Config rules to monitor the compliance of EC2 and VPC resources in the developer AWS accounts. If developers launch unapproved EC2 instances or if developers create VPCs without DynamoDB gateway endpoints, perform a remediation action to terminate the unapproved resources.

Question #188 / 557

A security engineer is configuring encryption for sensitive financial records stored in Amazon S3.

Which encryption method satisfies these requirements?

A

Server-side encryption with Amazon S3 managed keys (SSE-S3)

B

Server-side encryption with AWS KMS managed keys (SSE-KMS)

C

Server-side encryption with customer-provided keys (SSE-C)

D

Question #241 / 557

A company is operating a REST API using Amazon API Gateway integrated with AWS Lambda. They need to simultaneously run two different versions of their API for A/B testing purposes. What is the MOST effective method to implement this?

A

Use a custom query parameter to specify the API version and configure the Lambda function to process requests accordingly.

B

Implement an API Gateway canary release deployment to split traffic between the two versions based on a percentage.

C

Apply an API Gateway resource policy that routes incoming requests to the appropriate version based on the client's IP address.

D

Deploy each API version as a separate stage with distinct endpoints and utilize stage variables to manage environment-specific configurations.
