A company hosts its website in the us-east-1 Region. The company is preparing to deploy its website into the eu-central-1 Region. Website visitors who are located in Europe should access the website that is hosted in eu-central-1. All other visitors access the website that is hosted in us-east-1. The company uses Amazon Route 53 to manage the website's DNS records.
Which routing policy should a SysOps administrator apply to the Route 53 record set to meet these requirements?

• A.Geolocation routing policy
• B.Geoproximity routing policy
• C.Latency routing policy
• D.Multivalue answer routing policy

A SysOps administrator needs to give users the ability to upload objects to an Amazon S3 bucket. The SysOps administrator creates a presigned URL and provides the URL to a user, but the user cannot upload an object to the S3 bucket. The presigned URL has not expired, and no bucket policy is applied to the S3 bucket.
Which of the following could be the cause of this problem?

• A.The SysOps administrator must apply a bucket policy to the S3 bucket to allow the user to upload the object.
• B.The user has not properly configured the AWS CLI with their access key and secret access key.
• C.The SysOps administrator does not have the necessary permissions to upload the object to the S3 bucket.
• D.The object already has been uploaded through the use of the presigned URL, so the presigned URL is no longer valid.

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

A company has deployed a web application in a VPC that has subnets in three Availability Zones. The company launches three Amazon EC2 instances from an EC2 Auto Scaling group behind an Application Load Balancer (ALB).
A SysOps administrator notices that two of the EC2 instances are in the same Availability Zone, rather than being distributed evenly across all three Availability Zones. There are no errors in the Auto Scaling group's activity history.
What is the MOST likely reason for the unexpected placement of EC2 instances?

• A.The Auto Scaling group was configured for only two Availability Zones.
• B.Amazon EC2 Auto Scaling randomly placed the instances in Availability Zones.
• C.One Availability Zone did not have sufficient capacity for the requested EC2 instance type.
• D.The ALB was configured for only two Availability Zones.

A company asks a SysOps administrator to ensure that AWS CloudTrail files are not tampered with after they are created. Currently, the company uses AWS Identity and Access Management (IAM) to restrict access to specific trails. The company's security team needs the ability to trace the integrity of each file.
What is the MOST operationally efficient solution that meets these requirements?

• A.Enable the CloudTrail file integrity feature on the trail. The security team can use the digest file that is created by CloudTrail to verify the integrity of the delivered files.
• B.Create an Amazon EventBridge (Amazon CloudWatch Events) rule that invokes an AWS Lambda function when a new file is delivered. Configure the Lambda function to compute an MD5 hash check on the file and store the result in an Amazon DynamoDB table. The security team can use the values that are stored in DynamoDB to verify the integrity of the delivered files.
• C.Enable the CloudTrail file integrity feature on an Amazon S3 bucket. Create an IAM policy that grants the security team access to the file integrity logs that are stored in the S3 bucket.
• D.Create an AWS Lambda function that is invoked each time a new file is delivered to the CloudTrail bucket. Configure the Lambda function to compute an MD5 hash check on the file and store the result as a tag in an Amazon 53 object. The security team can use the information in the tag to verify the integrity of the delivered files.
