Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q485-Q490):

NEW QUESTION # 485
A media company hosts its website on AWS. The website application's architecture includes a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB) and a database that is hosted on Amazon Aurora The company's cyber security teem reports that the application is vulnerable to SOL injection.
How should the company resolve this issue?

Answer: C

Explanation:
Explanation
https://aws.amazon.com/premiumsupport/knowledge-center/waf-block-common-attacks/#:~:text=To%20protect%
----------------------------------------------------------------------------------------------------------------------- Protect against SQL injection and cross-site scripting To protect your applications against SQL injection and cross-site scripting (XSS) attacks, use the built-in SQL injection and cross-site scripting engines. Remember that attacks can be performed on different parts of the HTTP request, such as the HTTP header, query string, or URI.
Configure the AWS WAF rules to inspect different parts of the HTTP request against the built-in mitigation engines.


NEW QUESTION # 486
A solutions architect must design a solution that uses Amazon CloudFront with an Amazon S3 origin to serve a static website. The solution must use AWS WAF to inspect all website traffic.

Answer: D

Explanation:
The correct and secure approach is to use Amazon CloudFront with Origin Access Control (OAC) to protect the S3 origin and attach AWS WAF to the CloudFront distribution to inspect and filter traffic at the edge before reaching the origin.
From AWS Documentation:
"AWS WAF is integrated with Amazon CloudFront, allowing inspection of HTTP(S) requests at the edge location before forwarding to your origin. To restrict direct access to the S3 bucket, use Origin Access Control (OAC)." (Source: Amazon CloudFront Developer Guide - Serving private content) Why Option D is correct:
* CloudFront is the only service that integrates with AWS WAF for full HTTP layer inspection.
* Origin Access Control (OAC) ensures that only CloudFront can access the S3 origin-replacing older Origin Access Identity (OAI) features.
* The S3 bucket policy is configured to trust requests only from CloudFront using OAC signed requests.
Why the other options are incorrect:
* Option A: WAF ARN is not a principal in S3 bucket policy. IAM does not support bucket policies based on WAF ARNs.
* Option B: Incorrect - CloudFront doesn't "forward requests to WAF"; rather, WAF is associated with CloudFront and inspects requests at the edge.
* Option C: S3 does not use security groups; they are for EC2/network interfaces. This shows a misunderstanding of how S3 works.

NEW QUESTION # 487
A company has an application that collects data from loT sensors on automobiles. The data is streamed and stored in Amazon S3 through Amazon Kinesis Date Firehose The data produces trillions of S3 objects each year. Each morning, the company uses the data from the previous 30 days to retrain a suite of machine learning (ML) models.
Four times each year, the company uses the data from the previous 12 months to perform analysis and train other ML models The data must be available with minimal delay for up to 1 year. After 1 year, the data must be retained for archival purposes.
Which storage solution meets these requirements MOST cost-effectively?

Answer: C


NEW QUESTION # 488
A company has a relational database workload that runs on Amazon Aurora MySQL. According to new compliance standards, the company must rotate all database credentials every 30 days. The company needs a solution that maximizes security and minimizes development effort.
Which solution will meet these requirements?

Answer: D

Explanation:
The correct answer is A because the company needs to rotate database credentials every 30 days while maximizing security and minimizing development effort. AWS Secrets Manager is the AWS service specifically designed to store, manage, and rotate secrets such as database usernames and passwords. It supports automatic rotation for supported databases, including Amazon Aurora MySQL , which makes it the most secure and operationally efficient solution.
With Secrets Manager, credentials are encrypted at rest, access can be controlled through IAM policies, and applications can retrieve secrets programmatically without embedding them in source code or configuration files. Automatic rotation reduces the risk associated with static credentials and helps meet compliance requirements with minimal manual work. Because rotation is built into the service, the development effort is significantly lower than creating and maintaining custom rotation logic.
Option B can work, but it requires building and operating a custom Lambda rotation function , which adds complexity compared with the native automation available in Secrets Manager. Options C and D are not best practices because storing credentials in environment files or configuration files increases security risk and does not provide a managed secrets lifecycle.
AWS security best practices recommend centralizing sensitive credentials in AWS Secrets Manager and enabling automatic rotation whenever possible. This improves security posture, reduces operational overhead, and aligns directly with compliance requirements for regular credential changes. Therefore, storing Aurora MySQL credentials in Secrets Manager with 30-day automatic rotation is the best solution.


NEW QUESTION # 489
A company collects data from thousands of remote devices by using a RESTful web services application that runs on an Amazon EC2 instance. The EC2 instance receives the raw data, transforms the raw data, and stores all the data in an Amazon S3 bucket. The number of remote devices will increase into the millions soon. The company needs a highly scalable solution that minimizes operational overhead.
Which combination of steps should a solutions architect take to meet these requirements9 (Select TWO.)

Answer: B,E

Explanation:
"RESTful web services" => API Gateway.
"EC2 instance receives the raw data, transforms the raw data, and stores all the data in an Amazon S3 bucket" => GLUE with (Extract - Transform - Load)
