NEW QUESTION # 603
A developer is creating an application that uses an AWS Lambda function to transform and load data from an Amazon S3 bucket. When the developer tests the application, the developer finds that some invocations of the Lambda function are slower than others.
The developer needs to update the Lambda function to have predictable invocation durations that run with low latency. Any initialization activities, such as loading libraries and instantiating clients, must run during allocation time rather than during actual function invocations.
Which combination of steps will meet these requirements? (Select TWO.)
Answer: B,D
NEW QUESTION # 604
A company's application runs on a fleet of Amazon EC2 instances in a VPC within private subnets that do not have public internet access. The company uses Amazon CloudWatch to monitor the application.
A developer is troubleshooting an issue with the application. Some performance metrics are not being published to CloudWatch. The developer uses EC2 Instance Connect to access an EC2 instance. The developer verifies that a CloudWatch agent is pre-installed and running.
The developer needs to ensure that the performance metrics are published to CloudWatch.
Which solution will meet this requirement in the MOST secure way?
Answer: A
Explanation:
The EC2 instances are in private subnets with no public internet access, yet the CloudWatch agent must publish metrics to Amazon CloudWatch. To send metrics, the instances need: (1) network connectivity to CloudWatch APIs, and (2) IAM permissions that allow the agent to publish metrics and logs.
The most secure approach is to avoid opening outbound internet access via a NAT gateway (which increases the network attack surface) and instead use AWS PrivateLink through a VPC interface endpoint for CloudWatch. An interface endpoint provides private connectivity from the VPC to CloudWatch without traversing the public internet.
On the permissions side, AWS provides the managed IAM policy CloudWatchAgentServerPolicy, which is intended for the CloudWatch agent running on servers to publish metrics/logs. Attaching this policy to the EC2 instance profile role provides the needed permissions while keeping scope appropriate (unlike an admin policy).
Why the other options are not best:
* A uses CloudWatchAgentAdminPolicy (broader permissions than needed) and a NAT gateway (public internet path). That is not "most secure."
* B is irrelevant here because the agent is already installed and running; the issue is publishing connectivity/permissions.
* D grants read-only access, which cannot publish metrics, so it cannot fix the issue.
Therefore, attach CloudWatchAgentServerPolicy to the instance role and create a VPC interface endpoint for CloudWatch.
NEW QUESTION # 605
A developer is designing an event-driven architecture. An AWS Lambda function that processes data needs to push processed data to a subset of four consumer Lambda functions. The data must be routed based on the value of one field in the data.
Which solution will meet these requirements with the LEAST operational overhead?
Answer: A
NEW QUESTION # 606
A company uses an AWS CloudFormation template to deploy and manage its AWS infrastructure. The CloudFormation template creates Amazon VPC security groups and Amazon EC2 security groups.
A manager finds out that some engineers modified the security groups of a few EC2 instances for testing purposes. A developer needs to determine what modifications occurred.
Which solution will meet this requirement?
Answer: D
NEW QUESTION # 607
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: B
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.
Reference: Switching unauthenticated users to authenticated users (identity pools), Allow user access to your API without authentication (Anonymous user access)
