Amazon AWS Certified Developer - Associate Sample Questions (Q537-Q542):

NEW QUESTION # 537
A company's website runs on an Amazon EC2 instance and uses Auto Scaling to scale the environment during peak times. Website users across the world are experiencing high latency due to static content on the EC2 instance, even during non-peak hours.
Which combination of steps will resolve the latency issue? (Choose two.)

Answer: C,E

Explanation:
Option (D), creating an Amazon CloudFront distribution to cache static content, is the most recommended solution. CloudFront is a global content delivery network (CDN) that can cache static content on servers distributed around the world. This can help significantly reduce latency for users around the world. Option (E), storing your application's static content in Amazon S3, can also help reduce latency. S3 is a high-performance object storage service that can be used to store static content.


NEW QUESTION # 538
An ecommerce startup is preparing for an annual sales event. As the traffic to the company's application increases, the development team wants to be notified when the Amazon EC2 instance's CPU utilization exceeds 80%.
Which solution will meet this requirement?

Answer: B

Explanation:
Step-by-Step Breakdown:
Requirement Summary:
* Get notified when EC2 CPU Utilization > 80%
Option A: CloudWatch Alarm with SNS
* Correct and standard AWS practice
* CloudWatch automatically collects EC2 metrics, including CPUUtilization.
* You can set a CloudWatch Alarm with a threshold (80% in this case).
* Then, trigger an SNS notification to email, SMS, Lambda, etc.
Option B: AWS CloudTrail alarm
* Incorrect: CloudTrail logs API activity, not performance metrics.
* It doesn't track metrics like CPU utilization.
Option C: Cron job on EC2 running --describe-instance-information
* Incorrect: This doesn't give CPU usage.
* Also inefficient, and polling is bad practice when CloudWatch already monitors this natively.
Option D: Lambda function querying CloudTrail for CPU usage
* Incorrect and conceptually flawed.
* CloudTrail does not store performance metrics; CloudWatch does.

The cluster runs behind an Application Load Balancer The application stores data in an Amazon Aurora database A developer encrypts and manages database credentials inside the application The company wants to use a more secure credential storage method and implement periodic credential rotation.
Which solution will meet these requirements with the LEAST operational overhead?

Answer: D

Explanation:
* Secrets Management: AWS Secrets Manager is designed specifically for storing and managing sensitive credentials.
* Built-in Rotation: Secrets Manager provides automatic secret rotation functionality, enhancing security posture significantly.
* IAM Integration: IAM policies and roles grant fine-grained access to ECS Fargate, ensuring the principle of least privilege.
* Reduced Overhead: This solution centralizes secrets management and automates rotation, reducing operational overhead compared to the other options.

NEW QUESTION # 540
A developer is creating an application that reads and writes to multiple Amazon S3 buckets. The application will be deployed to an Amazon EC2 instance. The developer wants to make secure API requests from the EC2 instances without the need to manage the security credentials for the application. The developer needs to apply the principle of least privilege.
Which solution will meet these requirements?

Answer: A


NEW QUESTION # 541
A developer is building an application that uses an Amazon RDS for PostgreSQL database. To meet security requirements, the developer needs to ensure that data is encrypted at rest. The developer must be able to rotate the encryption keys on demand. Which solution will meet these requirements?

Answer: D

Explanation:
A customer-managed AWS Key Management Service (KMS) key allows for encryption at rest and provides the ability to rotate the key on demand. This ensures compliance with security requirements for key management and database encryption. RDS integrates natively with AWS KMS, allowing the use of a customer-managed key for encrypting data at rest.
Key rotation can be managed directly in AWS KMS without needing custom solutions.
