A large company has a business-critical application that runs in a single AWS Region. The application consists of multiple Amazon EC2 instances and an amazon RDS Multi-AZ DB instance. The EC2 instances run in an Amazon EC2 Scaling group across multiple Availability Zones.
A solution architect is implementing a disaster recovery (DR) plan for the application. The solution architect has created a pilot light application deployments in a new Region, which Is referred as the RD Region. The DR environment has an Auto Scaling group with a single EC2 instance and a read replica of the RDS DB instance.
The solution architect must automate a failover from the primary application environment to the pilot light environment in the DR Region.
Which solution meets the requirements with the MOST operational efficiency?
A large company runs workloads in VPCs that are deployed of AWS accounts. Each VPC consists of public subnets and private subnets that span across multiple Availability Zones. NAT gateway are deployed in the public subnets and allow outbound connectivity to the internet from the private subnets.
A solution architect is working on a hub-and-spoke design. All private subnets in the spoke VPCs must route traffic to the internal through an aggress VPC. The solutions architect already has deployed has deployed a NAT gateway in an egress VPC in a central AWS account.
Which set of additional steps should the solution architect take to meet these requirements?
A solutions architect is troubleshooting an application that runs on Amazon EC2 instances. The EC2 instances runs in an Auto Scaling group. The application needs to access user data in an Amazon DynamoDB table that has fixed provisioned capacity.
To match the increased workload, the solutions architect recently doubled the maximum size of the Auto Scaling group. New, when many instances launch at the same time, some application components are throttled when the component scan the DynamoDB table. The Auto Scaling group terminates the falling instances and starts new instances unit all applications are running.
A solution architect must implement a solution to mitigate the throttling issue in the MOST cost-effective manner.

A company has an on-premises Microsoft SQL Server database that writes a nightly 200 GB export to a local drive. The company wants to move the backups to more robust cloud storage on Amazon S3. The company has set up a 10 Gbps AWS Direct Connect connection between the on-premises data center and AWS. Which solution meets these requirements Most cost effectively?
A large company is running a popular web application The application runs on several Amazon EC2 Linux instances in an Auto Scaling group in a private subnet An Application Load Balancer is targeting the instances in the Auto Scaling group in the private subnet. AWS Systems Manager Session Manager is configured, and AWS Systems Manager Agent is running on all the EC2 instances.
The company recently released a new version of the application Some EC2 instances are now being marked as unhealthy and are being terminated. As a result, the application is running at reduced capacity A solutions architect tries to determine the root cause by analyzing Amazon CloudWatch logs that are collected from the application, but the logs are Inconclusive
How should the solutions architect gam access to an EC2 instance to troubleshoot the issue?
