A company uses an AWS CodeCommit repository. The company must store a backup copy of the data that is in the repository in a second AWS Region. Which solution will meet these requirements?
Answer: C
A company has multiple business units that each have separate accounts on AWS. Each business unit manages its own network with several VPCs that have CIDR ranges that overlap. The company’s marketing team has created a new internal application and wants to make the application accessible to all the other business units. The solution must use private IP addresses only. Which solution will meet these requirements with the LEAST operational overhead?
Answer: C
With AWS PrivateLink, the marketing team can create an endpoint service to share their internal application with other accounts securely using private IP addresses. They can grant permission to specific AWS accounts to connect to the service and create interface VPC endpoints in the other accounts to access the application by using private IP addresses. This option does not require any changes to the network of the other business units, and it does not require peering or NATing. This solution is both scalable and secure.

A company needs to audit the security posture of a newly acquired AWS account. The company’s data security team requires a notification only when an Amazon S3 bucket becomes publicly exposed. The company has already established an Amazon Simple Notification Service (Amazon SNS) topic that has the data security team's email address subscribed. Which solution will meet these requirements?
Answer: B
A. No, because Amazon S3 can NOT currently publish notifications for isPublic events. https://docs.aws.amazon.com/AmazonS3/latest/userguide/EventNotifications.html B. Yes, because IAM Access Analyzer for S3 alerts you to S3 buckets that are configured to allow access to anyone on the internet or other AWS accounts https://aws.amazon.com/blogs/security/how-to-prioritize-iam-access-analyzer-findings/ C. No, because PutBucketPolicy notifies us of an Amazon S3 bucket policy event to an Amazon S3 bucket, and we are looking for a SPECIFIC event to the bucket permissions, not ALL events. D. No, because cloudtrail-s3-dataevents-enabled checks if at least one AWS CloudTrail trail is logging Amazon Simple Storage Service (Amazon S3) data events for all S3 buckets. https://docs.aws.amazon.com/config/latest/developerguide/cloudtrail-s3-dataevents-enabled.html

A solutions architect needs to assess a newly acquired company’s portfolio of applications and databases. The solutions architect must create a business case to migrate the portfolio to AWS. The newly acquired company runs applications in an on-premises data center. The data center is not well documented. The solutions architect cannot immediately determine how many applications and databases exist. Traffic for the applications is variable. Some applications are batch processes that run at the end of each month. The solutions architect must gain a better understanding of the portfolio before a migration to AWS can begin. Which solution will meet these requirements?
Answer: C
C. Use Migration Evaluator to generate a list of servers. Build a report for a business case. Use AWS Migration Hub to view the portfolio. Use AWS Application Discovery Service to gain an understanding of application dependencies.

A company has an application that runs as a ReplicaSet of multiple pods in an Amazon Elastic Kubernetes Service (Amazon EKS) cluster. The EKS cluster has nodes in multiple Availability Zones. The application generates many small files that must be accessible across all running instances of the application. The company needs to back up the files and retain the backups for 1 year. Which solution will meet these requirements while providing the FASTEST storage performance?
Answer: A
Explanation: Amazon EFS provides shared file storage that is highly available and durable. It is an ideal solution to share files between containers running on multiple instances in a cluster. Mounting an Amazon EFS file system on each subnet provides a shared file system for multiple instances running in different Availability Zones. Additionally, AWS Backup provides automated backup and recovery of Amazon EFS file systems.

A company runs a customer service center that accepts calls and automatically sends all customers a managed, interactive, two-way experience survey by text message. The applications that support the customer service center run on machines that the company hosts in an on-premises data center. The hardware that the company uses is old, and the company is experiencing downtime with the system. The company wants to migrate the system to AWS to improve reliability. Which solution will meet these requirements with the LEAST ongoing operational overhead?
Answer: A
Amazon Connect is a cloud-based contact center service that allows you to set up a virtual call center for your business. It provides an easy-to-use interface for managing customer interactions through voice and chat. Amazon Connect integrates with other AWS services, such as Amazon S3 and Amazon Kinesis, to help you collect, store, and analyze customer data for insights into customer behavior and trends. On the other hand, Amazon Pinpoint is a marketing automation and analytics service that allows you to engage with your customers across different channels, such as email, SMS, push notifications, and voice. It helps you create personalized campaigns based on user behavior and enables you to track user engagement and retention. While both services allow you to communicate with your customers, they serve different purposes. Amazon Connect is focused on customer support and service, while Amazon Pinpoint is focused on marketing and engagement.

A company is building a call center by using Amazon Connect. The company’s operations team is defining a disaster recovery (DR) strategy across AWS Regions. The contact center has dozens of contact flows, hundreds of users, and dozens of claimed phone numbers. Which solution will provide DR with the LOWEST RTO?
Answer: D
The solution that will provide DR with the LOWEST RTO (Recovery Time Objective) is option D. Option D provisions a new Amazon Connect instance with all existing users and contact flows in a second Region. It also sets up an Amazon Route 53 health check for the URL of the Amazon Connect instance, an Amazon CloudWatch alarm for failed health checks, and an AWS Lambda function to deploy an AWS CloudFormation template that provisions claimed phone numbers. This option allows for the fastest recovery time because all the necessary components are already provisioned and ready to go in the second Region. In the event of a disaster, the failed health check will trigger the AWS Lambda function to deploy the CloudFormation template to provision the claimed phone numbers, which is the only missing component.

A company runs an application on AWS. The company curates data from several different sources. The company uses proprietary algorithms to perform data transformations and aggregations. After the company performs ETL processes, the company stores the results in Amazon Redshift tables. The company sells this data to other companies. The company downloads the data as files from the Amazon Redshift tables and transmits the files to several data customers by using FTP. The number of data customers has grown significantly. Management of the data customers has become difficult. The company will use AWS Data Exchange to create a data product that the company can use to share data with customers. The company wants to confirm the identities of the customers before the company shares data. The customers also need access to the most recent data when the company publishes the data. Which solution will meet these requirements with the LEAST operational overhead?
Answer: B
I think it's B. According to https://aws.amazon.com/data-exchange/why-aws-data-exchange/redshift-data-tables/ Customers can find and subscribe to third-party data in AWS Data Exchange and directly query the data in minutes in Amazon Redshift without extracting, transforming, or loading it. In B, customers can query Redshift directly. No need to use S3 periodically. Minimizes operational overhead.

A solutions architect is designing a solution to process events. The solution must have the ability to scale in and out based on the number of events that the solution receives. If a processing error occurs, the event must move into a separate queue for review. Which solution will meet these requirements?
Answer: A
Configuring scaling based on the age of the oldest message is nowhere near as good as scaling based on size of the Queue for this use case. age of the oldest message will grow linearly based on time. If there is a dramatic spike in the Queue size due to increased traffic, like 100X increase in size. Then the queue will have grown a lot but the oldest message will only increase in age linearly, so the scaling will not be able to realize how much the workload has increased.

A company has a web application that allows users to upload short videos. The videos are stored on Amazon EBS volumes and analyzed by custom recognition software for categorization. The website contains static content that has variable traffic with peaks in certain months. The architecture consists of Amazon EC2 instances running in an Auto Scaling group for the web application and EC2 instances running in an Auto Scaling group to process an Amazon SQS queue. The company wants to re-architect the application to reduce operational overhead using AWS managed services where possible and remove dependencies on third-party software. Which solution meets these requirements?
Answer: C
This solution meets the requirements by using multiple managed services offered by AWS which can reduce the operational overhead. Hosting the web application in Amazon S3 would make it highly available, scalable and can handle variable traffic. The uploaded videos can be stored in S3 and processed using S3 event notifications that trigger a Lambda function, which calls the Amazon Rekognition API to categorize the videos. SQS can be used to process the event notifications and also it is a managed service. This solution eliminates the need to manage EC2 instances, EBS volumes and the custom software. Additionally, using Lambda function in this case, eliminates the need for managing additional servers to process the SQS queue which will reduce operational overhead. By using this solution, the company can benefit from the scalability, reliability, and cost-effectiveness that these services offer, which can help to reduce operational overhead and improve the overall performance and security of the application.
