NEW QUESTION # 281
A developer is creating a mobile application that will not require users to log in.
What is the MOST efficient method to grant users access to AWS resources'?
Answer: A
Explanation:
This solution is the most efficient method to grant users access to AWS resources without requiring them to log in. Amazon Cognito is a service that provides user sign-up, sign-in, and access control for web and mobile applications. Amazon Cognito identity pools support both authenticated and unauthenticated users. Unauthenticated users receive access to your AWS resources even if they aren't logged in with any of your identity providers (IdPs). You can use Amazon Cognito to associate unauthenticated users with an IAM role that has limited access to resources, such as Amazon S3 buckets or DynamoDB tables. This degree of access is useful to display content to users before they log in or to allow them to perform certain actions without signing up. Using an identity provider to securely authenticate with the application will require users to log in, which does not meet the requirement. Creating an AWS Lambda function to create an IAM user when a user accesses the application will incur unnecessary costs and complexity, and may pose security risks if not implemented properly. Creating credentials using AWS KMS and applying them to users when using the application will also incur unnecessary costs and complexity, and may not provide fine-grained access control for resources.
NEW QUESTION # 282
A developer deploys a custom application to three Amazon EC2 instances. The application processes messages from an Amazon Simple Queue Service (Amazon SQS) standard queue with default settings. When the developer runs a load test on the Amazon SQS queue, the developer discovers that the application processes many messages multiple times.
How can the developer ensure that the application processes each message exactly once?
Answer: A
Explanation:
https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO- queues-moving.html Moving from a standard queue to a FIFO queue:
If you have an existing application that uses standard queues and you want to take advantage of the ordering or exactly-once processing features of FIFO queues, you need to configure the queue and your application correctly.
Note:
You can't convert an existing standard queue into a FIFO queue. To make the move, you must either create a new FIFO queue for your application or delete your existing standard queue and recreate it as a FIFO queue.
NEW QUESTION # 283
A cloud-based video surveillance company is developing an application that analyzes video files. After the application analyzes the files, the company can discard the files.
The company stores the files in an Amazon S3 bucket. The files are 1 GB in size on average. No file is larger than 2 GB. An AWS Lambda function will run one time for each video file that is processed. The processing is very I/O intensive, and the application must read each file multiple times.
Which solution will meet these requirements in the MOST performance-optimized way?
Answer: D
Explanation:
The workload is explicitly very I/O intensive and requires reading the same file multiple times. Reading repeatedly from S3 across the network will introduce latency and repeated network I/O. For best performance, the function should download the file once to fast local storage and perform all repeated reads locally.
AWS Lambda provides ephemeral storage mounted at /tmp. AWS allows increasing this ephemeral storage beyond the default size. Because the files are at most 2 GB, the developer can configure the Lambda function' s ephemeral storage to 2 GB and copy each S3 object into /tmp before processing. This converts repeated network reads into repeated local filesystem reads, which is significantly faster and more consistent for I/O- heavy workloads.
Option D (read directly from S3) is the least optimized because each pass over the file requires additional network I/O and S3 GET requests.
Option A is not feasible: Lambda cannot directly attach and manage an EBS volume like an EC2 instance can.
Option B is not applicable: ENA is an EC2 networking feature; Lambda networking is managed by the service and does not allow attaching ENAs for performance tuning in that way.
Because the files are disposable after processing, using ephemeral /tmp storage is also cost-effective and operationally simple, and it is aligned with the "process once per file" pattern.
Therefore, increase Lambda ephemeral storage and copy the video into /tmp for repeated reads.
NEW QUESTION # 284
A developer is writing an application that will run on Amazon EC2 instances in an Auto Scaling group. The developer wants to externalize the session state to support the application.
Which AWS services or resources can the developer use to meet these requirements? (Choose two.)
Answer: C,D
NEW QUESTION # 285
A developer is writing an application for a company. The application will be deployed on Amazon EC2 and will use an Amazon RDS for Microsoft SQL Server database. The company's security team requires that database credentials are rotated at least weekly.
How should the developer configure the database credentials for this application?
Answer: A
Explanation:
The requirement is to rotate database credentials at least weekly. The AWS service that is purpose-built for storing and automatically rotating secrets is AWS Secrets Manager. Secrets Manager supports rotation schedules (including daily, weekly, or custom intervals) and integrates with supported databases through rotation Lambda functions. With rotation enabled, Secrets Manager can periodically generate a new password, update the secret value, and apply the new credential to the database user, while allowing applications to retrieve the current credential securely at runtime.
Option C matches this best practice: create a database user, store the username/password in a Secrets Manager secret, and enable rotation (daily rotation more than satisfies a weekly requirement). Applications on EC2 can retrieve the secret at startup or on a refresh interval using the AWS SDK, and can cache it according to best practices to reduce API calls, while still supporting rotation.
Option A (Parameter Store secure string) encrypts parameters, but Parameter Store does not provide the same managed secret rotation workflow for database credentials; rotating the KMS key is not the same as rotating the database password. Option B is not applicable as stated for RDS for Microsoft SQL Server: IAM database authentication is supported for specific engines (commonly MySQL and PostgreSQL) and is not the standard mechanism for SQL Server password rotation. Option D is insecure and operationally fragile: embedding long-lived credentials in user data and environment variables makes rotation difficult and increases exposure risk.
Therefore, the most secure and compliant configuration is C: store DB credentials in AWS Secrets Manager and enable automated rotation on an interval that meets or exceeds the weekly rotation requirement.
