44. A company has two applications: a sender application that sends messages with payloads to be processed and a processing application intended to receive the messages with payloads. The company wants to implement an AWS service to handle messages between the two applications. The sender application can send about 1,000 messages each hour. The messages may take up to 2 days to be processed If the messages fail to process, they must be retained so that they do not impact the processing of any remaining messages.

Which solution meets these requirements and is the MOST operationally efficient?

Set up an Amazon EC2 instance running a Redis database Configure both applications to use the instance Store process, and delete the messages., respectively

Use an Amazon Kinesis data stream to receive the messages from the sender application. Integrate the processing application with the Kinesis Client Library (KCL).

Integrate the sender and processor applications with an Amazon Simple Queue Service (Amazon SQS) queue Configure a dead-letter queue to collect the messages that failed to process

Subscribe the processing application to an Amazon Simple Notification Service (Amazon SNS) topic to receive notifications to process, integrate the sender application to write to the SNS topic.

45. The application's traffic is often low. but it occasionally grows significantly. During these sudden increases in traffic, DynamoDB returns throttling errors. The result is that error pages are displayed to end users.

What should a solutions architect do to reduce these errors?

Change the DynamoDB table to use on-demand capacity mode.

Create a DynamoDB read replica to scale the read traffic horizontally.

Purchase DynamoDB reserved capacity of 1,000 RCUs and 500 WCUs.

Configure the application to use strongly consistent reads for DynamoDB queries.

46. A company needs to provide its employees with secure access lo confidential and sensilive files. The company wants to ensure that the tiles can be accessed only by authorized users. The files must be downloaded securely to the employees' devices.

The tiles are stored in an on-premises Windows file server. However, due to an increase in remote usage, the file server is running out of capacity.

Which solution will meet these requirements?

Migrate the file server to an Amazon EC2 instance in a public subnet. Configure the security group to limit inbound traffic to the employees' IP addresses.

Migrate the files to an Amazon FSx for Windows File Server file system. Integrate the Amazon FSx file system with the on-premises Active Directory. Configure AWS Client VP

Migrate the tiles to Amazon S3, and create a private VPC endpoint. Create a signed URL to allow download.

Migrate the tiles to Amazon S3, and create a public VPC endpoint. Allow employees to sign on with AWS Single Sign-On.

47. A company runs a website on Amazon EC2 instances behind an ELB Application Load Balancer Amazon Route 53 Is used for the DNS. The company wants to set up a backup website with a message including a phone number and email address that users can reach if the primary website is down.

How should the company deploy this solution?

Use Amazon S3 website hosting for the backup website and a Route 53 failover routing policy

Use Amazon S3 website hosting for the backup website and a Route 53 latency routing policy

Deploy the application in another AWS Region and use ELB health checks for failover routing.

Deploy the application in another AWS Region and use server-side redirection on the primary website

48. A company wants to migrate its MySQL database from on premises to AWS. The company recently experienced a database outage that significantly impacted the business To ensure this does not happen again the company wants a reliable database solution on AWS that minimizes data loss and stores every transaction on at least two nodes

Which solution meets these requirements?

Create an Amazon RDS DB instance with synchronous replication to three nodes in three Availability Zones.

Create an Amazon RDS MySQL DB instance with Multi-AZ functionality enabled to synchronously replicate the data.

Create an Amazon RDS MySQL DB instance and then create a read replica in a separate AWS Region that synchronously replicates the data.

Create an Amazon EC2 instance with a MySQL engine installed that triggers an AWS Lambda function to synchronously replicate the data to an Amazon RDS MySQL DB instance

49. A company operates a two-tier application for image processing. The application uses two Availability Zones, each with one public subnet and one private subnet. An Application Load Balancer (ALB) for the web tier uses the public subnets. Amazon EC2 instances for the application tier use the private subnets.

Users report that the application is running more slowly than expected. A security audit of the web server log files shows that the application is receiving millions of illegitimate requests from a small number of IP addresses. A solutions architect needs to resolve the immediate performance problem while the company investigates a more permanent solution.

What should the solutions architect recommend to meet this requirement?

Modify the inbound security group for the web tier. Add a deny rule for the IP addresses that are consuming resources.

Modify the network ACL for the web tier subnets. Add an inbound deny rule for the IP addresses that are consuming resources.

Modify the inbound security group for the application tier. Add a deny rule for the IP addresses that are consuming resources.

Modify the network ACL for the application tier subnets. Add an inbound deny rule for the IP addresses that are consuming resources.

50. A company hosts an online shopping application that stores all orders in an Amazon RDS for PostgreSQL Single-AZ DB instance Management wants to eliminate single points of failure and has asked a solutions architect to recommend an approach to minimize database downtime without requiring any changes to the application code

Which solution meets these requirements?

Convert the existing database instance to a Multi-AZ deployment by modifying the database instance and specifying the Multi-AZ option

Create a new RDS Multi-AZ deployment Take a snapshot of the current RDS instance and restore the new Multi-AZ deployment with the snapshot

Create a read-only replica of the PostgreSQL database m another Availability Zone Use Amazon Route 53 weighted record sets to distribute requests across the databases

Place the RDS for PostgreSQL database in an Amazon EC2 Auto Scaling group with a minimum group size of two Use Amazon Route 53 weighted record sets to distribute requests across instances
