Amazon AWS Certified Solutions Architect - Associate (SAA-C03) Exam Sample Questions (Q192-Q197):

NEW QUESTION # 192
A company is designing an application. The application uses an AWS Lambda function to receive information through Amazon API Gateway and to store the information in an Amazon Aurora PostgreSQL database.
During the proof-of-concept stage, the company has to increase the Lambda quotas significantly to handle the high volumes of data that the company needs to load into the database. A solutions architect must recommend a new design to improve scalability and minimize the configuration effort.
Which solution will meet these requirements?

A. Change the platform from Aurora to Amazon DynamoDB. Provision a DynamoDB Accelerator (DAX) cluster. Use the DAX client SDK to point the existing DynamoDB API calls at the DAX cluster.
B. Set up two Lambda functions. Configure one function to receive the information. Configure the other function to load the information into the database. Integrate the Lambda functions by using an Amazon Simple Queue Service (Amazon SQS) queue.
C. Refactor the Lambda function code to Apache Tomcat code that runs on Amazon EC2 instances.
Connect the database by using native Java Database Connectivity (JDBC) drivers.
D. Set up two Lambda functions. Configure one function to receive the information. Configure the other function to load the information into the database. Integrate the Lambda functions by using Amazon Simple Notification Service (Amazon SNS).

Answer: B

Explanation:

bottlenecks can be avoided with queues (SQS).

NEW QUESTION # 193
A Solutions Architect is working for a large global media company with multiple office locations all around the world. The Architect is instructed to build a system to distribute training videos to all employees. Using CloudFront, what method would be used to serve content that is stored in S3, but not publicly accessible from S3 directly?

A. Create an Identity and Access Management (IAM) user for CloudFront and grant access to the objects in your S3 bucket to that IAM user.
B. Create an S3 bucket policy that lists the CloudFront distribution ID as the principal and the target bucket as the Amazon Resource Name (ARN).
C. Create an Origin Access Identity (OAI) for CloudFront and grant access to the objects in your S3 bucket to that OAI.
D. Create a web ACL in AWS WAF to block any public S3 access and attach it to the Amazon CloudFront distribution.

Answer: C

Explanation:
When you create or update a distribution in CloudFront, you can add an origin access identity (OAI) and automatically update the bucket policy to give the origin access identity permission to access your bucket. Alternatively, you can choose to manually change the bucket policy or change ACLs, which control permissions on individual objects in your bucket.

You can update the Amazon S3 bucket policy using either the AWS Management Console or the Amazon S3 API:
- Grant the CloudFront origin access identity the applicable permissions on the bucket.
- Deny access to anyone that you don't want to have access using Amazon S3 URLs.
Hence, the correct answer is: Create an Origin Access Identity (OAI) for CloudFront and grant access to the objects in your S3 bucket to that OAI.
The option that says: Create an Identity and Access Management (IAM) user for CloudFront and grant access to the objects in your S3 bucket to that IAM user is incorrect because you cannot directly create an IAM User for a specific Amazon CloudFront distribution. You have to use an origin access identity (OAI) instead.
The option that says: Create an S3 bucket policy that lists the CloudFront distribution ID as the principal and the target bucket as the Amazon Resource Name (ARN) is incorrect because setting up an Amazon S3 bucket policy won't suffice. You have to first create an OAI in CloudFront and use that OAI as an authorized user in your Amazon S3 bucket.
The option that says: Create a web ACL in AWS WAF to block any public S3 access and attach it to the Amazon CloudFront distribution is incorrect because AWS WAF is primarily used to protect your applications from common web vulnerabilities and not for ensuring exclusive access to CloudFront.

NEW QUESTION # 194
A company has deployed a server less application that invokes an AWS Lambda function when new documents are uploaded to an Amazon S3 bucket The application uses the Lambda function to process the documents After a recent marketing campaign the company noticed that the application did not process many of The documents What should a solutions architect do to improve the architecture of this application?

A. Configure an S3 bucket replication policy Stage the documents m the S3 bucket for later processing
B. Create an Amazon Simple Queue Service (Amazon SOS) queue Send the requests to the queue Configure the queue as an event source for Lambda.
C. Set the Lambda function's runtime timeout value to 15 minutes
D. Deploy an additional Lambda function Load balance the processing of the documents across the two Lambda functions

Answer: A

NEW QUESTION # 195
A company recently migrated to AWS and wants to implement a solution to protect the traffic that flows in and out of the production VPC. The company had an inspection server in its on-premises data center. The inspection server performed specific operations such as traffic flow inspection and traffic filtering. The company wants to have the same functionalities in the AWS Cloud.
Which solution will meet these requirements?

A. Use AWS Network Firewall to create the required rules for traffic inspection and traffic filtering for the production VPC.
B. Use Amazon GuardDuty for traffic inspection and traffic filtering in the production VPC
C. Use AWS Firewall Manager to create the required rules for traffic inspection and traffic filtering for the production VPC.
D. Use Traffic Mirroring to mirror traffic from the production VPC for traffic inspection and filtering.

Answer: A

NEW QUESTION # 196
A company hosts its application on AWS The company uses Amazon Cognito to manage users When users log in to the application the application fetches required data from Amazon DynamoDB by using a REST API that is hosted in Amazon API Gateway. The company wants an AWS managed solution that will control access to the REST API to reduce development efforts Which solution will meet these requirements with the LEAST operational overhead?

A. For each user, create and assign an API key that must be sent with each request Validate the key by using an AWS Lambda function
B. Configure an AWS Lambda function to be an authorize! in API Gateway to validate which user made the request
C. Configure an Amazon Cognito user pool authorizer in API Gateway to allow Amazon Cognito to validate each request
D. Send the user's email address in the header with every request Invoke an AWS Lambda function to validate that the user with that email address has proper access

Answer: C

Explanation:
https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-integrate-with-cognito.html To control access to the REST API and reduce development efforts, the company can use an Amazon Cognito user pool authorizer in API Gateway. This will allow Amazon Cognito to validate each request and ensure that only authenticated users can access the API. This solution has the LEAST operational overhead, as it does not require the company to develop and maintain any additional infrastructure or code.
