NEW QUESTION # 499
A company hosts an application in a private subnet. The company has already integrated the application with Amazon Cognito. The company uses an Amazon Cognito user pool to authenticate users.
The company needs to modify the application so the application can securely store user documents in an Amazon S3 bucket.
Which combination of steps will securely integrate Amazon S3 with the application? (Select TWO.)
Answer: C,D
Explanation:
To securely integrate Amazon S3 with an application that uses Amazon Cognito for user authentication, the following two steps are essential:
Step 1: Create an Amazon Cognito Identity Pool (Option A)
Amazon Cognito Identity Poolsallow users to obtain temporary AWS credentials to access AWS resources, such as Amazon S3, after successfully authenticating with the Cognito user pool. The identity pool bridges the gap between user authentication and AWS service access by generating temporary credentials using AWS Identity and Access Management (IAM).
Once a user logs in using theCognito User Pool, the identity pool providesIAM roles with specific permissionsthat the application can use to access S3 securely. This ensures that each user has appropriate access controls while accessing the S3 bucket.
This is a secure way to ensure that users only have temporary and least-privilege access to the S3 bucket for their documents.
Step 2: Create an Amazon S3 VPC Endpoint (Option C)
By creating anAmazon S3 VPC endpoint, the company ensures that communication between the application (which is hosted in a private subnet) and the S3 bucket occurs over theAWS private network, without the need to traverse the internet. This enhances security and prevents exposure of data to public networks.
TheVPC endpointallows the application to access the S3 bucket privately and securely within the VPC. It also ensures that traffic stays within the AWS network, reducing attack surface and improving overall security.
Why the Other Options Are Incorrect:
Option B: This is incorrect becauseAmazon Cognito User Poolsare used for user authentication, not for generating S3 access tokens. To provide S3 access, you need to useAmazon Cognito Identity Pools, which offer AWS credentials.
Option D: ANAT gatewayis unnecessary in this scenario. Using aVPC endpointfor S3 access provides a more secure and cost-effective solution by keeping traffic within AWS.
Option E: Attaching a policy to restrict access based on IP addresses is not scalable or efficient. It would require managing users' dynamic IP addresses, which is not an effective security measure for this use case.

NEW QUESTION # 500
When controlling access to Amazon EC2 resources, each Amazon EBS Snapshot has a ______ attribute that controls which AWS accounts can use the snapshot.
Answer: D
Explanation:
Each Amazon EBS Snapshot has a createVolumePermission attribute that you can set to one or more AWS Account IDs to share the AMI with those AWS Accounts. To allow several AWS Accounts to use a particular EBS snapshot, you can use the snapshots's createVolumePermission attribute to include a list of the accounts that can use it.

NEW QUESTION # 501
A company has an ecommerce checkout workflow that writes an order to a database and calls a service to process the payment. Users are experiencing timeouts during the checkout process. When users resubmit the checkout form, multiple unique orders are created for the same desired transaction.
How should a solutions architect refactor this workflow to prevent the creation of multiple orders?
Answer: B
Explanation:
Explanation
This approach ensures that the order creation and payment processing steps are separate and atomic. By sending the order information to an SQS FIFO queue, the payment service can process the order one at a time and in the order they were received. If the payment service is unable to process an order, it can be retried later, preventing the creation of multiple orders. The deletion of the message from the queue after it is processed will prevent the same message from being processed multiple times.
NEW QUESTION # 502
A company uses an on-premises network-attached storage (NAS) system to provide file shares to its high performance computing (HPC) workloads. The company wants to migrate its latency-sensitive HPC workloads and its storage to the AWS Cloud. The company must be able to provide NFS and SMB multi- protocol access from the file system.
Which solution will meet these requirements with the LEAST latency? (Select TWO.)
Answer: A,E
Explanation:
A cluster placement group is a logical grouping of EC2 instances within a single Availability Zone that are placed close together to minimize network latency. This is suitable for latency-sensitive HPC workloads that require high network performance. A compute optimized EC2 instance is an instance type that has a high ratio of vCPUs to memory, which is ideal for compute-intensive applications. Amazon FSx for NetApp ONTAP is a fully managed service that provides NFS and SMB multi-protocol access from the file system, as well as features such as data deduplication, compression, thin provisioning, and snapshots. This solution will meet the requirements with the least latency, as it leverages the low-latency network and storage performance of AWS.

2 describes the characteristics and use cases of compute optimized EC2 instances.
