A company is hosting a static website on Amazon S3 and is using Amazon Route 53 for DNS. The website is experiencing increased demand from around the world. The company must decrease latency for users who access the website. Which solution meets these requirements MOST cost-effectively?

Add an Amazon CloudFront distribution in front of the S3 bucket. Edit the Route 53 entries to point to the CloudFront distribution. Amazon CloudFront is a content delivery network (CDN) service that distributes content globally to reduce latency. By setting up a CloudFront distribution in front of the S3 bucket hosting the static website, you can take advantage of its edge locations around the world to deliver content from the nearest location to the users, reducing the latency they experience. CloudFront automatically caches and replicates content to its edge locations, resulting in faster delivery and lower latency for users worldwide. This solution is highly effective in optimizing performance while keeping costs under control because CloudFront charges are based on actual data transfer and requests, and the pay-as-you-go pricing model ensures that you only pay for what you use.

A company uses NFS to store large video files in on-premises network attached storage. Each video file ranges in size from 1 MB to 500 GB. The total storage is 70 TB and is no longer growing. The company decides to migrate the video files to Amazon S3. The company must migrate the video files as soon as possible while using the least possible network bandwidth. Which solution will meet these requirements?

B. On a Snowball Edge device you can copy files with a speed of up to 100Gbps. 70TB will take around 5600 seconds, so very quickly, less than 2 hours. The downside is that it'll take between 4-6 working days to receive the device and then another 2-3 working days to send it back and for AWS to move the data onto S3 once it reaches them. Total time: 6-9 working days. Bandwidth used: 0. C. File Gateway uses the Internet, so maximum speed will be at most 1Gbps, so it'll take a minimum of 6.5 days and you use 70TB of Internet bandwidth. D. You can achieve speeds of up to 10Gbps with Direct Connect. Total time 15.5 hours and you will use 70TB of bandwidth. However, what's interesting is that the question does not specific what type of bandwidth? Direct Connect does not use your Internet bandwidth, as you will have a dedicate peer to peer connectivity between your on-prem and the AWS Cloud, so technically, you're not using your "public" bandwidth.

A company maintains a searchable repository of items on its website. The data is stored in an Amazon RDS for MySQL database table that contains more than 10 million rows.

The company has noticed slow application performance and wants to improve the performance as much as possible. Which solution will meet these requirements with the LEAST operational overhead?

Create an Amazon AppFlow flow to transfer data between each SaaS source and the S3 bucket. Configure an S3 event notification to send events to an Amazon Simple Notification Service (Amazon SNS) topic when the upload to the S3 bucket is complete. configuring Auto-Scaling also takes time when compared to AppFlow, in AWS's words "in just a few clicks" > Amazon AppFlow is a fully managed integration service that enables you to securely transfer data between Software-as-a-Service (SaaS) applications like Salesforce, SAP, Zendesk, Slack, and ServiceNow, and AWS services like Amazon S3 and Amazon Redshift, in just a few clicks

A global company hosts its web application on Amazon EC2 instances behind an Application Load Balancer (ALB). The web application has static data and dynamic data. The company stores its static data in an Amazon S3 bucket. The company wants to improve performance and reduce latency for the static data and dynamic data. The company is using its own domain name registered with Amazon Route 53. What should a solutions architect do to meet these requirements?

Create an Amazon CloudFront distribution that has the S3 bucket and the ALB as origins. Configure Route 53 to route traffic to the CloudFront distribution. Explanation - AWS Global Accelerator vs CloudFront • They both use the AWS global network and its edge locations around the world • Both services integrate with AWS Shield for DDoS protection. • CloudFront • Improves performance for both cacheable content (such as images and videos) • Dynamic content (such as API acceleration and dynamic site delivery) • Content is served at the edge • Global Accelerator • Improves performance for a wide range of applications over TCP or UDP • Proxying packets at the edge to applications running in one or more AWS Regions. • Good fit for non-HTTP use cases, such as gaming (UDP), IoT (MQTT), or Voice over IP • Good for HTTP use cases that require static IP addresses • Good for HTTP use cases that required deterministic, fast regional failover

A company has thousands of edge devices that collectively generate 1 TB of status alerts each day. Each alert is approximately 2 KB in size.

Which combination of actions should a solutions architect take to ensure that the Lambda function ingests all data in the future? (Choose two.)

Create an Amazon Simple Queue Service (Amazon SQS) queue, and subscribe it to the SNS topic. Modify the Lambda function to read from an Amazon Simple Queue Service (Amazon SQS) queue. Key: network connectivity issues

An application development team is designing a microservice that will convert large images to smaller, compressed images. When a user uploads an image through the web interface, the microservice should store the image in an Amazon S3 bucket, process and compress the image with an AWS Lambda function, and store the image in its compressed form in a different S3 bucket.A solutions architect needs to design a solution that uses durable, stateless components to process the images automatically.Which combination of actions will meet these requirements? (Choose two.)

Create an Amazon Simple Queue Service (Amazon SQS) queue. Configure the S3 bucket to send a notification to the SQS queue when an image is uploaded to the S3 bucket. Configure the Lambda function to use the Amazon Simple Queue Service (Amazon SQS) queue as the invocation source. When the SQS message is successfully processed, delete the message in the queue ------- To design a solution that uses durable, stateless components to process images automatically, a solutions architect could consider the following actions: Option A involves creating an SQS queue and configuring the S3 bucket to send a notification to the queue when an image is uploaded. This allows the application to decouple the image upload process from the image processing process and ensures that the image processing process is triggered automatically when a new image is uploaded. Option B involves configuring the Lambda function to use the SQS queue as the invocation source. When the SQS message is successfully processed, the message is deleted from the queue. This ensures that the Lambda function is invoked only once per image and that the image is not processed multiple times.

A company runs a highly available image-processing application on Amazon EC2 instances in a single VPC. The EC2 instances run inside several subnets across multiple Availability Zones. The EC2 instances do not communicate with each other. However, the EC2 instances download images from Amazon S3 and upload images to Amazon S3 through a single NAT gateway. The company is concerned about data transfer charges. What is the MOST cost-effective way for the company to avoid Regional data transfer charges?

Deploying a gateway VPC endpoint for Amazon S3 is the most cost-effective way for the company to avoid Regional data transfer charges. A gateway VPC endpoint is a network gateway that allows communication between instances in a VPC and a service, such as Amazon S3, without requiring an Internet gateway or a NAT device. Data transfer between the VPC and the service through a gateway VPC endpoint is free of charge, while data transfer between the VPC and the Internet through an Internet gateway or NAT device is subject to data transfer charges. By using a gateway VPC endpoint, the company can reduce its data transfer costs by eliminating the need to transfer data through the NAT gateway to access Amazon S3. This option would provide the required connectivity to Amazon S3 and minimize data transfer charges.

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?

Use AWS Network Firewall to create the required rules for traffic inspection and traffic filtering for the production VPC. AWS Network Firewall is a managed firewall service that provides filtering for both inbound and outbound network traffic. It allows you to create rules for traffic inspection and filtering, which can help protect your production VPC.

A company has an application that runs on Amazon EC2 instances and uses an Amazon Aurora database. The EC2 instances connect to the database by using user names and passwords that are stored locally in a file. The company wants to minimize the operational overhead of credential management.What should a solutions architect do to accomplish this goal?

Use AWS Secrets Manager. Turn on automatic rotation. AWS Secrets Manager is a secrets management service that helps you protect access to your applications, services, and IT resources. This service enables you to rotate, manage, and retrieve database credentials, API keys, and other secrets throughout their lifecycle.

A company has a production workload that runs on 1,000 Amazon EC2 Linux instances. The workload is powered by third-party software. The company needs to patch the third-party software on all EC2 instances as quickly as possible to remediate a critical security vulnerability.What should a solutions architect do to meet these requirements?

Use AWS Systems Manager Run Command to run a custom command that applies the patch to all EC2 instances. It provides the capability to execute a custom command across a large number of instances, which is ideal for applying a specific patch quickly. While Patch Manager is also a strong contender, its suitability depends on whether it supports the specific third-party software needing the patch. If it does, then Option B could also be a viable choice. However, for maximum flexibility and control over the patching process, particularly for third-party software, the Run Command is likely the best option.

A company needs the ability to analyze the log files of its proprietary application. The logs are stored in JSON format in an Amazon S3 bucket. Queries will be simple and will run on-demand. A solutions architect needs to perform the analysis with minimal changes to the existing architecture.What should the solutions architect do to meet these requirements with the LEAST amount of operational overhead?

Use Amazon Athena directly with Amazon S3 to run the queries as needed. Keyword: - Queries will be simple and will run on-demand. - Minimal changes to the existing architecture. This is simple query we can apply Athena directly on S3

A company runs an ecommerce application on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto Scaling group across multiple Availability Zones. The Auto Scaling group scales based on CPU utilization metrics. The ecommerce application stores the transaction data in a MySQL 8.0 database that is hosted on a large EC2 instance.The database's performance degrades quickly as application load increases. The application handles more read requests than write transactions. The company wants a solution that will automatically scale the database to meet the demand of unpredictable read workloads while maintaining high availability. Which solution will meet these requirements?

Use Amazon Aurora with a Multi-AZ deployment. Configure Aurora Auto Scaling with Aurora Replicas. Aurora is a fully managed, MySQL-compatible relational database that is designed for high performance and high availability. Aurora Multi-AZ deployments automatically maintain a synchronous standby replica in a different Availability Zone to provide high availability. Additionally, Aurora Auto Scaling allows you to automatically scale the number of Aurora Replicas in response to read workloads, allowing you to meet the demand of unpredictable read workloads while maintaining high availability. This would provide an automated solution for scaling the database to meet the demand of the application while maintaining high availability.

A company observes an increase in Amazon EC2 costs in its most recent bill. The billing team notices unwanted vertical scaling of instance types for a couple of EC2 instances. A solutions architect needs to create a graph comparing the last 2 months of EC2 costs and perform an in-depth analysis to identify the root cause of the vertical scaling. How should the solutions architect generate the information with the LEAST operational overhead?

Use Cost Explorer's granular filtering feature to perform an in-depth analysis of EC2 costs based on instance types. Cost Management dashboard can work but it's not the same, this just gives you a report of an OVERVIEW, so this is not in-depth
