A company needs to run its external website on Amazon EC2 instances and on-premises virtualized servers The AWS environment has a 1 GB AWS Direct Connect connection to the data center. The application has IP addresses that will not change. The on-premises and AWS servers are able to restart themselves while maintaining the same IP address if a failure occurs Some website users have to add their vendors to an allow list, so the solution must have a fixed IP address The company needs a solution with the lowest operational overhead to handle this split traffic.
What should a solutions architect do to meet these requirements?

• A.Deploy a Network Load Balancer on AWS. Create target groups for the on-premises and AWS IP addresses.
• B.Deploy an Application Load Balancer on AWS Register the on-premises and AWS IP addresses with the target group.
• C.Deploy Amazon API Gateway to direct traffic to the on-premises and AWS IP addresses based on the header of the request.
• D.Deploy an Amazon Route 53 Resolver with rules pointing to the on-premises and AWS IP addresses

Your company has an on-premises multi-tier PHP web application, which recently experienced downtime due to a large burst in web traffic due to a company announcement Over the coming days, you are expecting similar announcements to drive similar unpredictable bursts, and are looking to find ways to quickly improve your infrastructures ability to handle unexpected increases in traffic.
The application currently consists of 2 tiers a web tier which consists of a load balancer and several Linux Apache web servers as well as a database tier which hosts a Linux server hosting a MySQL database.
Which scenario below will provide full site functionality, while helping to improve the ability of your application in the short timeframe required?

• A.Failover environment: Create an S3 bucket and configure it for website hosting. Migrate your DNS to Route53 using zone file import, and leverage Route53 DNS failover to failover to the S3 hosted website.
• B.Hybrid environment: Create an AMI, which can be used to launch web servers in EC2. Create an Auto Scaling group, which uses the AMI to scale the web tier based on incoming traffic. Leverage Elastic Load Balancing to balance traffic between on-premises web servers and those hosted in AWS.
• C.Offload traffic from on-premises environment: Setup a CIoudFront distribution, and configure CloudFront to cache objects from a custom origin. Choose to customize your object cache behavior, and select a TTL that objects should exist in cache.
• D.Migrate to AWS: Use VM Import/Export to quickly convert an on-premises web server to an AMI. Create an Auto Scaling group, which uses the imported AMI to scale the web tier based on incoming traffic.
  Create an RDS read replica and setup replication between the RDS instance and on-premises MySQL server to migrate the database.

A company has an application running on Amazon EC2 instances in a private subnet. The application needs to store and retrieve data in Amazon S3 To reduce costs, the company wants to configure its AWS resources in a cost-effective manner.
How should the company accomplish this?

• A.Deploy a NAT gateway to access the S3 buckets
• B.Deploy an S3 gateway endpoint to access the S3 buckets
• C.Deploy AWS Storage Gateway to access the S3 buckets
• D.Deploy an S3 interface endpoint to access the S3 buckets.

A company hosts a multi-tier web application on Amazon Linux Amazon EC2 instances behind an Application Load Balancer The instances run in an Auto Scaling group across multiple Availability Zones The company observes that the Auto Scaling group launches more On-Demand Instances when the application's end users access high volumes of static web content The company wants to optimize cost What should a solutions architect do to redesign the application MOST cost-effectively?

• A.Create an Amazon CloudFront distribution to host the static web contents from an Amazon S3 bucket
• B.Update the Auto Scaling group to use Reserved Instances instead of On-Demand Instances
• C.Update the Auto Scaling group to scale by launching Spot Instances instead of On-Demand Instances
• D.Create an AWS Lambda function behind an Amazon API Gateway API to host the static website contents

A fitness tracking company serves users around the world, with its primary markets in North America and Asia. The company needs to design an infrastructure for its read-heavy user authorization application with the following requirements:
* Be resilient to problem with the application in any Region.
* Write to a database in a single Region.
* Read from multiple Regions.
* Support resiliency across application tiers in each Region.
* Support the relational database semantics reflected in the application.
Which combination of steps should a solutions architect take? (Choose two.)

• A.Deploy web, application, and MySQL database servers to Amazon EC2 instance in each Region. Set up the application so that reads and writes are local to the Region. Create snapshots of the web, application, and database servers and store the snapshots in an Amazon S3 bucket in both Regions.
  Set up cross-Region replication for the database layer.
• B.Use an Amazon Route 53 geoproximity routing policy combined with a multivalue answer routing policy.
• C.Set up web, application, and Amazon RDS for MySQL instances in each Region. Set up the application so that reads are local and writes are partitioned based on the user. Set up a Multi-AZ failover for the web, application, and database servers. Set up cross-Region replication for the database layer.
• D.Set up active-active web and application servers in each Region. Deploy an Amazon Aurora global database with clusters in each Region. Set up the application to use the in-Region Aurora database endpoints. Create snapshots of the web application servers and store them in an Amazon S3 bucket in both Regions.
• E.Use an Amazon Route 53 geolocation routing policy combined with a failover routing policy.
