How can you allow a user from one AWS account to access and manage resources in another AWS account? Configure cross-origin resource sharing Configure web identity federation Configure cross-account access Configure Cognito3. Which of the following statements is not true for SNS? SNS Messages can be retrieved at a later date Messages are sent to all subscribers4. Which statement best describes IAM? IAM allows you to manage users' passwords only. AWS staff must create new users for your organization. This is done by raising a ticket. IAM stands for Improvised Application Management, and it allows you to deploy and manage applications in the AWS Cloud. IAM allows you to manage permissions for AWS resources only. IAM allows you to manage users, groups, and roles and their corresponding level of access to the AWS Platform.5. ######QUESTION#########When Jacob's company first created an AWS account, he began with a single sign-in principal called a root user account that had complete access to all AWS services and resources. What should he do to adhere to best practices for using the root user account? It should be accessible using the access_key_id and secret_access_key_id It should be accessible by one admin only after enabling Multi-factor authentication6. When using Web Identity Federation to allow a user to access an AWS service (such as an S3 bucket), which of the following is the correct order of steps? A user logs in to the AWS platform using their Facebook credentials. AWS authenticate with Facebook to check the credentials. Temporary Security Access is granted to AWS. A user makes the AssumeRoleWithWebIdentity API Call. The user is then redirected to Facebook to authenticate. Once authenticated, the user is given an ID token. The user is then granted temporary access to the AWS platform. Users cannot use Facebook credentials to access the AWS platform. A user authenticates with Facebook first. They are then given an ID token by Facebook, which they can then trade for temporary security credentials.7. You are a Developer working with AWS CloudFormation templates.

In front of the instances is an Internet-facing load balancer that takes requests from clients over the internet and distributes them to the EC2 instances. A health check is configured to ping the index.html page found in the root directory for the health status. When accessing the website via the internet visitors of the website receive timeout errors.

You are working on a mobile phone app for an online retailer that stores customer data in DynamoDB. You would like to allow new users to sign-up using their Facebook credentials. What is the recommended approach? Embed encrypted AWS credentials into the application code, so that the application can access DynamoDB on the user's behalf. After the user has authenticated with Facebook, allow them to download encrypted AWS credentials to their device so that the mobile app can access DynamoDB After the user has successfully logged in to Facebook and received an authentication token, Cognito should be used to exchange the token for temporary access to DynamoDB Write your own custom code which allows the user to log in via Facebook and receive an authentication token, then calls the AssumeRoleWithWebIdentity API and exchanges the authentication tokens for temporary access to DynamoDB20.

What should you do to identify the true IP address of the client? Look into the X-Forwarded-Proto header in the backend Look into the X-Forwarded-For header in the backend32. ######QUESTION#########Ben is working in a e-commerce company, he needs to improve its software delivery process and is moving away from the waterfall methodology. He decided that every application should be built using the best CI/CD practices and every application should be packaged and deployed as a Docker container.

What is the most likely issue? The ECR repository is stale, you must delete and re-create it The IAM permissions are wrong for the CodeBuild service33. A company has AWS Lambda functions where each is invoked by other AWS services such as Amazon Kinesis Data Firehose, Amazon API Gateway, Amazon Simple Storage Service or Amazon CloudWatch Events. What all functions have in common is that they all process heavy workloads such as big data analysis, large file processing, and statistical computations. What should you do to improve the performance of your AWS Lambda functions without changing your code? Increase the RAM assigned to your function Increase the instance type for your functions34. ######QUESTION#########Which of the following option is correct? "Kinesis Stream" : Kinesis data streams can continuously capture gigabytes of data per second from hundreds of thousands of sources such as website clickstreams, database event streams, financial transactions, social media feeds, IT logs, and location-tracking events. "SNS" - SNS is appropriate for flexible message delivery over multiple transport protocols "SQS" - Amazon Simple Queue Service (Amazon SQS) offers a secure, durable, and available hosted queue that lets you integrate and decouple distributed software systems and components "Lambda" - AWS Lambda makes it easy to execute code in response to events, such as changes to Amazon S3 buckets, updates to an Amazon DynamoDB table, or custom events generated by your applications or devices.
