Question #903 / 1019

A company uses an Amazon S3 bucket to store critical data for multiple projects, each assigned a unique prefix. The company needs to ensure each project team can only access objects within their designated prefix and perform specific operations (e.g., read/write). The solution must minimize administrative complexity and operational overhead.

A

Create S3 access points for each project with policies restricting access to their respective prefixes.

B

Use S3 Batch Operations to apply object-level ACLs for each project's prefix.

C

Replicate data from each prefix into separate S3 buckets and configure bucket policies for each project.

D

Assign IAM roles to each project team with inline policies scoped to their prefix.

Question #570 / 1019

A company operates a nightly batch processing workload on Amazon EC2 instances spread across two Availability Zones in the us-west-2 Region. Under normal conditions, the workload runs on three instances but needs to scale up to eight instances every night. The company seeks a solution that minimizes operational overhead while ensuring the instances scale appropriately for the increased demand.

Which solution meets these requirements with the LEAST operational overhead?

A

Configure a CloudWatch Events rule to trigger an AWS Lambda function that modifies the Auto Scaling group capacity.

B

Configure an Auto Scaling group with a scheduled action to adjust capacity at specific times.

C

Configure an Auto Scaling group that requires manual scaling adjustments each night.

D

Configure an Auto Scaling group that uses dynamic scaling policies based on Amazon CloudWatch metrics.

Question #311 / 529

A company operates its application using Amazon EC2 instances and AWS Lambda functions. The EC2 instances maintain a consistent and predictable workload, while the Lambda functions face fluctuating and irregular demand. The application employs an Amazon ElastiCache for Redis cluster as a caching layer.

A solutions architect needs to propose a cost-optimized solution to reduce the company's monthly expenses.

Which solution meets these requirements?

A

Purchase an EC2 instance Savings Plan for the EC2 instances. Use a Compute Savings Plan for Lambda to cover the baseline usage. Acquire reserved nodes for the ElastiCache for Redis cluster.

B

Purchase a Compute Savings Plan to cover the EC2 instances. Use Lambda reserved concurrency for the peak Lambda demand. Acquire reserved nodes for the ElastiCache for Redis cluster.

C

Purchase a Compute Savings Plan to cover all EC2, Lambda, and ElastiCache resources entirely.

D

Purchase a Compute Savings Plan for the EC2 instances and ElastiCache nodes. Use Lambda reserved concurrency for the expected Lambda workload.

Question #248 / 529

An online learning platform uses Amazon API Gateway for its REST API, which is integrated with AWS Lambda. The API experiences weekly surges in excessive requests from around 800 different IP addresses that rotate each week, causing increased latency and timeouts. A solutions architect needs to mitigate this issue with the MOST operational efficiency. Which solution meets these requirements?

A

Use AWS Firewall Manager to create a security group policy to deny access from the IP addresses.

B

Create an AWS WAF web ACL with a rate-based rule, set the rule action to Block, and associate the web ACL with the API Gateway.

C

Use AWS Firewall Manager to create a security group policy to allow access only to specific CIDR ranges.

D

Create an AWS WAF web ACL with an IP set match rule, set the rule action to Block, and associate the web ACL with the API Gateway.

Sample Questions

Question #72 / 557

A developer creates a VPC named VPC-X that has public and private subnets. The developer deploys an Amazon RDS database inside the private subnet of VPC-X. To access this database, the developer configures an AWS Lambda function in the private subnet of a different VPC, VPC-Y. When the Lambda function is executed, it fails to connect to the RDS database. What should the developer do to resolve this issue?

A

Modify the RDS security group to allow all traffic from the VPC-Y CIDR block.

B

Redeploy the Lambda function in the same VPC-X private subnet as the RDS instance and update the RDS security group to permit traffic from the Lambda function's security group.

C

Establish a VPC peering connection between VPC-X and VPC-Y, update the route tables, and configure the RDS security group to allow traffic from VPC-Y's CIDR.

D

Create an IAM policy granting RDS access and attach it to the Lambda function's execution role.

Question #375 / 557

A company is building a serverless application using Amazon API Gateway HTTP API. They need to ensure that only authenticated users can invoke specific routes, and the authentication tokens must automatically expire and be refreshed periodically. Which approach meets these requirements?

A

Set up an Amazon Cognito identity pool, use the Cognito Authorizer in API Gateway, and utilize the temporary AWS credentials from the identity pool.

B

Implement a custom Lambda authorizer that validates tokens stored in a DynamoDB table, which are issued during user login and refreshed manually.

C

Configure an Amazon Cognito user pool, integrate it with API Gateway using a JWT authorizer, and use the issued access or identity tokens.

D
