Question 1

A scientific company needs to process text and image data from an Amazon S3 bucket. The data is collected from several radar stations during a live, time-critical phase of a deep space mission. The radar stations upload the data to the source S3 bucket. The data is prefixed by radar station identification number.

The company created a destination S3 bucket in a second account. Data must be copied from the source S3 bucket to the destination S3 bucket to meet a compliance objective. The replication occurs through the use of an S3 replication rule to cover all objects in the source S3 bucket.

One specific radar station is identified as having the most accurate data. Data replication at this radar station must be monitored for completion within 30 minutes after the radar station uploads the objects to the source S3 bucket.

What should a solutions architect do to meet these requirements?

Options:

Set up an AWS DataSync agent to replicate the prefixed data from the source S3 bucket to the destination S3 bucket. Select to use all available bandwidth on the task, and monitor the task to ensure that it is in the TRANSFERRING status. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to trigger an alert if this status changes.

In the second account, create another S3 bucket to receive data from the radar station with the most accurate data. Set up a new replication rule for this new S3 bucket to separate the replication from the other radar stations. Monitor the maximum replication time to the destination. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to trigger an alert when the time exceeds the desired threshold.

Enable Amazon S3 Transfer Acceleration on the source S3 bucket, and configure the radar station with the most accurate data to use the new endpoint. Monitor the S3 destination bucket's TotalRequestLatency metric. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to trigger an alert if this status changes.

Create a new S3 replication rule on the source S3 bucket that filters for the keys that use the prefix of the radar station with the most accurate data. Enable S3 Replication Time Control (S3 RTC). Monitor the maximum replication time to the destination. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to trigger an alert when the time exceeds the desired threshold.

Question 2

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 retrieve approximately 1 TB of data each day from Amazon S3

The developer activity leads to excessive monthly data-transfer charges and NAT gateway processing charges between EC2 instances and S3 buckets, 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 wantthis enforcement to negatively affect the speed at which the developers can perform their tasks

Which solution will meet these requirements MOST cost-effectively?

Options:

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 S3 interface endpoints Scope the developers* IAM permissions so that the developers can launch VPC resources only with CloudFormation

Create a daily forecasted budget with AWS Budgets to monitor EC2 compute costs and S3 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

Create an AWS Service Catalog portfolio that users can use to create an approved VPC configuration with S3 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

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 S3 gateway endpoints perform a remediation action to terminate the unapproved resources

Question 3

A company manages hundreds of AWS accounts centrally in an organization in AWS Organizations. The company recently started to allow product teams to create and manage their own S3 access points in their accounts. The S3 access points can be accessed only within VPCs, not on the internet.

What is the MOST operationally efficient way to enforce this requirement?

Options:

Set the S3 access point resource policy to deny the s3:CreateAccessPoint action unless the s3:AccessPointNetworkOrigin condition key evaluates to vpc.

Create an SCP at the root level in the organization to deny the s3:CreateAccessPoint action unless the s3:AccessPointNetworkOrigin condition key evaluates to VPC.

Use AWS CloudFormation StackSets to create a new IAM policy in each AWS account that allows the s3:CreateAccessPoint action only if the s3:AccessPointNetworkOrigin condition key evaluates to VPC.

Set the S3 bucket policy to deny the s3:CreateAccessPoint action unless the s3:AccessPointNetworkOrigin condition key evaluates to VPC.

Answer:

Explanation:

The company wants a centralized enforcement mechanism across hundreds of AWS accounts. The control must ensure that any S3 access points that product teams create are VPC-only and cannot be internet-accessible. The most operationally efficient solution is one that applies across the organization without requiring per-account deployments, per-bucket policies, or per-access-point configuration.

Service control policies (SCPs) in AWS Organizations are designed to provide centralized guardrails that define the maximum available permissions for accounts in an organization. By attaching an SCP at the organization root (or to OUs as needed), the company can enforce that no principal in any account can create an S3 access point unless the request specifies a VPC network origin. This aligns directly with the requirement to enforce “VPC-only” access points consistently across all accounts with minimal ongoing operational work.

Option B uses an SCP at the root to deny s3:CreateAccessPoint unless the s3:AccessPointNetworkOrigin condition key evaluates to VPC. This is the correct organization-wide preventive control.

Option A is not correct because an S3 access point resource policy is attached to an access point after it exists and is primarily used to control access to the access point. It is not a reliable organization-wide preventive mechanism to enforce how access points are created across hundreds of accounts. Also, it requires access point-by-access point management, which increases operational overhead.

Option C is less operationally efficient because StackSets deployment across hundreds of accounts introduces additional operational steps and drift management. It also relies on account-level IAM permissions being properly used and does not provide a simple, centralized “cannot be bypassed” guardrail in the same way that an SCP does.

Option D is incorrect because S3 bucket policies control access to bucket resources and objects. They do not function as an organization-wide control to prevent creation of access points across accounts, and they would require bucket-by-bucket management rather than a centralized enforcement mechanism.

Therefore, a root-level SCP that denies access point creation unless the access point network origin is VPC is the most operationally efficient enforcement approach.
