A company uses an Amazon CloudFront distribution to deliver its website Traffic togs for the website must be centrally stored and all data must be encrypted at rest Which solution will meet these requirements?

• A.Create an Amazon S3 bucket that is configured with default server side encryption that uses AES-256 Configure CloudFront to use the S3 bucket as a log destination
• B.Create an Amazon S3 bucket that is configured with no default encryption Enable encryption in the CloudFront dtstnbubon and use the S3 bucket as a log destination
• C.Create an Amazon OpenSearch Service (Amazon Elasttcsearch Service) domain with internet access and server-side encryption that uses the default AWS managed key Configure CloudFront to use the Amazon OpenSearch Service (Amazon Elasticsearch Service) domain as a log destination

A company is running a flash sale on its website. The website is hosted on burstable performance Amazon EC2 instances in an Auto Scaling group. The Auto Scaling group is configured to launch instances when the CPU utilization is above 70%.
A couple of hours into the sale, users report slow load times and error messages for refused connections. A SysOps administrator reviews Amazon CloudWatch metrics and notices that the CPU utilization is at 20% across the entire fleet of instances.
The SysOps administrator must restore the website's functionality without making changes to the network infrastructure.
Which solution will meet these requirements?

• A.Activate unlimited mode for the instances in the Auto Scaling group.
• B.Implement an Amazon CloudFront distribution to offload the traffic from the Auto Scaling group.
• C.Move the website to a different AWS Region that is closer to the users.
• D.Reduce the desired size of the Auto Scaling group to artificially increase CPU average utilization.

A SysOps administrator is setting up an automated process to recover an Amazon EC2 instance In the event of an underlying hardware failure. The recovered instance must have the same private IP address and the same Elastic IP address that the original instance had. The SysOps team must receive an email notification when the recovery process is initiated.
Which solution will meet these requirements?

• A.Create an Amazon CloudWatch alarm for the EC2 instance, and specify the SiatusCheckFailedjnstance metric. Add an EC2 action to the alarm to recover the instance. Add an alarm notification to publish a message to an Amazon Simple Notification Service (Amazon SNS> topic. Subscribe the SysOps team email address to the SNS topic.
• B.Create an Amazon CloudWatch alarm for the EC2 Instance, and specify the StatusCheckFailed_System metric. Add an EC2 action to the alarm to recover the instance. Add an alarm notification to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the SysOps team email address to the SNS topic.
• C.Create an Auto Scaling group across three different subnets in the same Availability Zone with a minimum, maximum, and desired size of 1. Configure the Auto Seating group to use a launch template that specifies the private IP address and the Elastic IP address. Add an activity notification for the Auto Scaling group to send an email message to the SysOps team through Amazon Simple Email Service (Amazon SES).
• D.Create an Auto Scaling group across three Availability Zones with a minimum, maximum, and desired size of 1. Configure the Auto Scaling group to use a launch template that specifies the private IP address and the Elastic IP address. Add an activity notification for the Auto Scaling group to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic. Subscribe the SysOps team email address to the SNS topic.
