AWS Developer Associate(DVA-C01)- Quiz 6

Q1.
A developer is planning to launch as serverless application composed of AWS Lambda, Amazon API Gateway, and Amazon DynamoDB. What is the EASIEST way to deploy the application using simple syntax?

Use the Serverless Application Repository

Use the Serverless Application Model

Use AWS CloudFormation

Use AWS Elastic Beanstalk

WHY A IS False?	CONCEPT: Serverless Application Repository	Serverless Application Repository is a managed repository for serverless applications.
WHY B IS True?	CONCEPT: AWS Serverless Application Model (SAM)	AWS Serverless Application Model (SAM) is an open-source framework for building serverless applications. It provides shorthand syntax to express functions, APIs, databases, and event source mappings. With just a few lines per resource, you can define the application you want and model it using YAML. During deployment, SAM transforms and expands the SAM syntax into AWS CloudFormation syntax, enabling you to build serverless applications faster. To get started with building SAM-based applications, use the AWS SAM CLI. SAM CLI provides a Lambda-like execution environment that lets you locally build, test, and debug applications defined by SAM templates. You can also use the SAM CLI to deploy your applications to AWS.
WHY C IS False?	CONCEPT: AWS CloudFormation	This would not be the simplest way to package and deploy this infrastructure. Without using SAM, you would need to build out a much more complex AWS CloudFormation template yourself.
WHY D IS False?	CONCEPT: Elastic Beanstalk	Elastic Beanstalk cannot be used to deploy Lambda, API Gateway or DynamoDB.
Short Trick	"Read the EASIEST way to deploy the application using simple syntax" clearly indicates AWS Serverless Application Model (SAM) as it is made for this purpose only & an easy one.

Q2.
A team of Developers require access to an AWS account that is a member account in AWS Organizations. The administrator of the master account needs to restrict the AWS services, resources, and API actions that can be accessed by the users in the account. What should the administrator create?

An Organizational Unit

A Service Control Policy (SCP)

A Tag Policy

A Consolidated Billing account

WHY A IS False?	CONCEPT: An Organizational Unit	This is used to group accounts for administration.
WHY B IS True?	CONCEPT: A Service Control Policy (SCP)	As an administrator of the master account of an organization, you can use service control policies (SCPs) to specify the maximum permissions for member accounts in the organization. In SCPs, you can restrict which AWS services, resources, and individual API actions the users and roles in each member account can access. You can also define conditions for when to restrict access to AWS services, resources, and API actions.
WHY C IS False?	CONCEPT: A Tag Policy	These are used to maintain consistent tags, including the preferred case treatment of tag keys and tag values.
WHY D IS False?	CONCEPT: Consolidated billing	Consolidated billing is not related to controlling access to resources within an account..
Short Trick	It is a definition question, You have to learn defination of SCP

Q3.
A company is running an order processing system on AWS. Amazon SQS is used to queue orders and an AWS Lambda function processes them. The company recently started noticing a lot of orders are failing to process. How can a Developer MOST effectively manage these failures to debug the failed orders later and reprocess them, as necessary?

Publish failed orders from the order queue to an Amazon SNS topic

Log the failed orders from the order queue using Amazon CloudWatch Logs

Send failed orders from the order queue to AWS CloudTrail logs

Implement dead-letter queues for failed orders from the order queue

WHY A IS False?	CONCEPT: Amazon SNS topic	There is no way to isolate messages that have failed to process when subscribing an SQS queue to an SNS topic.
WHY B IS False?	CONCEPT: Amazon CloudWatch Logs	SQS does not publish message success/failure to CloudWatch Logs.
WHY C IS False?	CONCEPT: AWS CloudTrail logs	CloudTrail records API activity not performance metrics or logs.
WHY D IS True?	CONCEPT: dead-letter queues	Amazon SQS supports dead-letter queues, which other queues (source queues) can target for messages that can't be processed (consumed) successfully. Dead-letter queues are useful for debugging your application or messaging system because they let you isolate problematic messages to determine why their processing doesn't succeed. The Developer should therefore implement dead-letter queues for failed orders from the order queue. This will allow full debugging as the entire message is available for analysis.
Short Trick	1."Collect system-level metrics from on-premises servers & EC2 instances" & 2." Most efficiently"
