The following IAM policy is attached to an IAM group. This is the only policy applied to the group.
Correct Answer:
D
This answer is correct because it reflects the effect of the IAM policy on the group members. The policy has two statements: one with an Allow effect and one with a Deny effect. The Allow statement grants permission to perform any EC2 action on any resource within the us-east-1 Region. The Deny statement overrides the Allow statement and denies permission to perform the ec2:StopInstances and ec2:TerminateInstances actions on any resource within the us-east-1 Region, unless the group member is logged in with MFA. Therefore, the group members can perform any EC2 action except stopping or terminating instances in the us-east-1 Region, unless they use MFA.

A company sends AWS CloudTrail logs from multiple AWS accounts to an Amazon S3 bucket in a centralized account. The company must keep the CloudTrail logs. The company must also be able to query the CloudTrail logs at any time
Which solution will meet these requirements?
Correct Answer:
A
it allows the company to keep the CloudTrail logs and query them at any time. By using the CloudTrail event history in the centralized account, the company can view, filter, and download recent API activity across multiple AWS accounts. By creating an Amazon Athena table from the CloudTrail event history, the company can use a serverless interactive query service that makes it easy to analyze data in S3 using standard SQL. By querying the CloudTrail logs from Athena, the company can gain insights into user activity and resource changes. References:

A company recently announced the deployment of its retail website to a global audience. The website runs on multiple Amazon EC2 instances behind an Elastic Load Balancer. The instances run in an Auto Scaling group across multiple Availability Zones.
The company wants to provide its customers with different versions of content based on the devices that the customers use to access the website.
Which combination of actions should a solutions architect take to meet these requirements? (Choose two.)
Correct Answer:
AC
For C: IMPROVED USER EXPERIENCE Lambda@Edge can help improve your users' experience with your websites and web applications across the world, by letting you personalize content for them without sacrificing performance. Real-time Image Transformation You can customize your users' experience by transforming images on the fly based on the user characteristics. For example, you can resize images based on the viewer's device type—mobile, desktop, or tablet. You can also cache the transformed images at CloudFront Edge locations to further improve performance when delivering images. https://aws.amazon.com/lambda/edge/

A company needs to configure a real-time data ingestion architecture for its application. The company needs an API. a process that transforms data as the data is streamed, and a storage solution for the data.
Which solution will meet these requirements with the LEAST operational overhead?
Correct Answer:
C
It uses Amazon Kinesis Data Firehose which is a fully managed service for delivering real-time streaming data to destinations such as Amazon S3. This service requires less operational overhead as compared to option A, B, and D. Additionally, it also uses Amazon API Gateway which is a fully managed service for creating, deploying, and managing APIs. These services help in reducing the operational overhead and automating the data ingestion process.

A company is creating an application that runs on containers in a VPC. The application stores and accesses data in an Amazon S3 bucket During the development phase, the application will store and access 1 TB of data in Amazon S3 each day. The company wants to minimize costs and wants to prevent traffic from traversing the internet whenever possible.
Which solution will meet these requirements?
Correct Answer:
C
A gateway VPC endpoint for Amazon S3 enables private connections between the VPC and Amazon S3 that do not require an internet gateway or NAT device. This minimizes costs and prevents traffic from traversing the internet. A gateway VPC endpoint uses a prefix list as the route target in a VPC route table to route traffic privately to Amazon S31. Associating the endpoint with all route tables in the VPC ensures that all subnets can access Amazon S3 through the endpoint.
Option A is incorrect because S3 Intelligent-Tiering is a storage class that optimizes storage costs by automatically moving objects between two access tiers based on changing access patterns. It does not affect the network traffic between the VPC and Amazon S32.
Option B is incorrect because S3 Transfer Acceleration is a feature that enables fast, easy, and secure transfers of files over long distances between clients and an S3 bucket. It does not prevent traffic from traversing the internet3.
Option D is incorrect because an interface VPC endpoint for Amazon S3 is powered by AWS PrivateLink, which requires an elastic network interface (ENI) with a private IP address in each subnet. This adds complexity and cost to the solution. Moreover, an interface VPC endpoint does not support cross-Region access to Amazon S3.
