Question # 25

A software as a service (SaaS) company has developed a multi-tenant environment. The company uses Amazon DynamoDB tables that the tenants share tor the storage layer. The company uses AWS Lambda functions for the application services.

The company wants to offer a tiered subscription model that is based on resource consumption by each tenant Each tenant is identified by a unique tenant ID that is sent as part of each request to the Lambda functions The company has created an AWS Cost and Usage Report (AWS CUR) in an AWS account The company wants to allocate the DynamoDB costs to each tenant to match that tenant " s resource consumption

Which solution will provide a granular view of the DynamoDB cost for each tenant with the LEAST operational effort?

Associate a new lag that is named tenant ID with each table in DynamoDB Activate the tag as a cost allocation tag m the AWS Billing and Cost Management console Deploy new Lambda function code to log the tenant ID in Amazon CloudWatch Logs Use the AWS CUR to separate DynamoDB consumption cost for each tenant ID

Configure the Lambda functions to log the tenant ID and the number of RCUs and WCUs consumed from DynamoDB for each transaction to Amazon CloudWatch Logs Deploy another Lambda function to calculate the tenant costs by using the logged capacity units and the overall DynamoDB cost from the AWS Cost Explorer API Create an Amazon EventBridge rule to invoke the calculation Lambda function on a schedule.

Create a new partition key that associates DynamoDB items with individual tenants Deploy a Lambda function to populate the new column as part of each transaction Deploy another Lambda function to calculate the tenant costs by using Amazon Athena to calculate the number of tenant items from DynamoDB and the overall DynamoDB cost from the AWS CUR Create an Amazon EventBridge rule to invoke the calculation Lambda function on a schedule

Deploy a Lambda function to log the tenant ID the size of each response, and the duration of the transaction call as custom metrics to Amazon CloudWatch Logs Use CloudWatch Logs Insights to query the custom metrics for each tenant. Use AWS Pricing Calculator to obtain the overall DynamoDB costs and to calculate the tenant costs

Question # 28

A company is developing and hosting several projects in the AWS Cloud. The projects are developed across multiple AWS accounts under the same organization in AWS Organizations. The company requires the cost lor cloud infrastructure to be allocated to the owning project. The team responsible for all of the AWS accounts has discovered that several Amazon EC2 instances are lacking the Project tag used for cost allocation.

Which actions should a solutions architect take to resolve the problem and prevent it from happening in the future? (Select THREE.)

Create an AWS Config rule in each account to find resources with missing tags.

Create an SCP in the organization with a deny action for ec2:Runlnstances if the Project tag is missing.

Use Amazon Inspector in the organization to find resources with missing tags.

Create an IAM policy in each account with a deny action for ec2:RunInstances if the Project tag is missing.

Create an AWS Config aggregator for the organization to collect a list of EC2 instances with the missing Project tag.

Use AWS Security Hub to aggregate a list of EC2 instances with the missing Project tag.

Question # 30

A solutions architect is reviewing a company ' s process for taking snapshots of Amazon RDS DB instances. The company takes automatic snapshots every day and retains the snapshots for 7 days.

The solutions architect needs to recommend a solution that takes snapshots every 6 hours and retains the snapshots for 30 days. The company uses AWS Organizations to manage all of its AWS accounts. The company needs a consolidated view of the health of the RDS snapshots.

Which solution will meet these requirements with the LEAST operational overhead?

Turn on the cross-account management feature in AWS Backup. Create a backup plan that specifies the frequency and retention requirements. Add a tag to the DB instances. Apply the backup plan by using tags. Use AWS Backup to monitor the status of the backups.

Turn on the cross-account management feature in Amazon RDS. Create a snapshot global policy that specifies the frequency and retention requirements. Use the RDS console in the management account to monitor the status of the backups.

Turn on the cross-account management feature in AWS CloudFormation. From the management account, deploy a CloudFormation stack set that contains a backup plan from AWS Backup that specifies the frequency and retention requirements. Create an AWS Lambda function in the management account tomonitor the status of the backups. Create an Amazon EventBridge rule in each account to run the Lambda function on a schedule.

Configure AWS Backup in each account. Create an Amazon Data Lifecycle Manager lifecycle policy that specifies the frequency and retention requirements.

Question # 31

A company with global offices has a single 1 Gbps AWS Direct Connect connection to a single AWS Region. The company ' s on-premises network uses the connection to communicate with the company ' s resources in the AWS Cloud. The connection has a single private virtual interface that connects to a single VPC.

A solutions architect must implement a solution that adds a redundant Direct Connect connection in the same Region. The solution also must provide connectivity to other Regions through the same pair of Direct Connect connections as the company expands into other Regions.

Which solution meets these requirements?

Provision a Direct Connect gateway. Delete the existing private virtual interface from the existing connection. Create the second Direct Connect connection. Create a new private virtual interlace on each connection, and connect both private victual interfaces to the Direct Connect gateway. Connect the Direct Connect gateway to the single VPC.

Keep the existing private virtual interface. Create the second Direct Connect connection. Create a new private virtual interface on the new connection, and connect the new private virtual interface to the single VPC.

Question # 32

A company runs payment gateways in multiple AWS Regions. The company also operates on-premises data centers where the company manages hardware security modules (HSMs) to tokenize sensitive payment data to comply with security regulations.

To process payment transactions within the company ' s performance SLA, the company requires an automated and centrally managed solution that can provide dedicated private connectivity between the on-premises HSMs and AWS payment services.

Which solution will meet this requirement?

Use a centrally managed accelerator in AWS Global Accelerator to route traffic from each data center the nearest AWS Region.

Establish AWS Site-to-Site VPN connections between the data centers and AWS. Set up a centrally managed transit gateway and set appropriate routes.

Use AWS CloudHSM to tokenize the sensitive payment data. Deploy CloudHSM in the same private subnet as the payment services workload.

Set up AWS Cloud WAN with AWS Direct Connect attachments between on-premises data centers and AWS.

Full Access

Answer:

Explanation:

D is correct because the requirement explicitly calls for (1) dedicated private connectivity, (2) automated and centrally managed operation, and (3) connectivity between on-premises data centers and multiple AWS Regions.

AWS Direct Connect provides dedicated private connectivity from on-premises environments to AWS. This is the key differentiator versus internet-based connectivity options when performance and consistency are required to meet strict SLAs.

AWS Cloud WAN provides centralized, policy-based management of a global network across Regions and on-premises attachments. Using Direct Connect attachments to Cloud WAN lets the company centrally define routing/segmentation policies and connect multiple data centers to multiple Regions in a consistent, automated wayâ€”well aligned to â€œautomated and centrally managedâ€ requirements for a multi-Region payment platform.

Why the other options are incorrect:

A (Global Accelerator) improves performance for internet-facing endpoints using Anycast and edge routing, but it does not provide private, dedicated connectivity between on-premises networks and AWS services. It is not the right tool for private HSM-to-AWS service connectivity.

B (Site-to-Site VPN + Transit Gateway) can be centrally routed with Transit Gateway, but VPN tunnels run over the public internet and are not â€œdedicated private connectivity.â€ They can be acceptable for many cases, but they do not best meet â€œdedicated private connectivityâ€ and strict SLA expectations compared to Direct Connect.

C (CloudHSM) changes the architecture by moving tokenization into AWS-managed HSM infrastructure. The question states the company manages on-premises HSMs and needs private connectivity between those HSMs and AWS payment services, so replacing them with CloudHSM does not satisfy the stated connectivity requirement.
