A company stores critical data in Amazon S3. Which S3 feature is designed to protect against accidental deletion or overwriting of objects?

Cross-origin resource sharing (CORS)

What is the primary purpose of designing for high availability?

To ensure that no data is ever lost

To minimize downtime and ensure continuous operation during failures or maintenance

To improve application performance under heavy load

To reduce the cost of running the application

A solutions architect is defining reliability requirements for a new application. The business states that the application must be available 99.9% of the time over a month. Which type of requirement is this?

A recovery point objective (RPO) requirement

A recovery time objective (RTO) requirement

A company runs a stateful application on a single EC2 instance that stores data on an Amazon EBS volume. The application is critical, and the company wants to automate recovery if the instance fails. The application must recover with minimal data loss. Which solution meets this requirement?

Create an AMI of the instance and use a Lambda function to launch a new instance from the AMI if the original instance fails.

Place the EC2 instance in an Auto Scaling group with a minimum and maximum size of 1 and use an ELB health check to replace the instance if it fails.

Use Amazon Route 53 health checks to fail over to a static website hosted in Amazon S3 if the instance fails.

Configure the EC2 instance for automatic recovery with a CloudWatch alarm on the StatusCheckFailed metric. The alarm triggers the recovery action to restart the instance on a new host.

Which architecture is designed to tolerate the failure of an entire Availability Zone without requiring manual intervention?

Deploying the application on a single EC2 instance in one Availability Zone

Taking regular snapshots of the EC2 instance

Deploying the application across multiple Availability Zones with an Application Load Balancer and an Auto Scaling group

Using a larger EC2 instance type to handle more load
