A team of developers is using several Amazon S3 buckets as centralized repositories. Users across the world upload large sets of files to these repositories. The development team's applications later process these files. A SysOps administrator sets up a new S3 bucket. DOC-EXAMPLE-BUCKET, to support a new workload. The new S3 bucket also receives regular uploads of large sets of files from users worldwide.

Question 55

A SysOps administrator is trying to set up an Amazon Route 53 domain name to route traffic to a website hosted on Amazon S3. The domain name of the website is www.anycompany.com and the S3 bucket name is anycompany-static. After the record set is set up in Route 53, the domain name www.anycompany.com does not seem to work, and the static website is not displayed in the browser. Which of the following is a cause of this?

The S3 bucket must be configured with Amazon CloudFront first.

The Route 53 record set must have an IAM role that allows access to the S3 bucket.

Question 58

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?

One Availability Zone did not have sufficient capacity for the requested EC2 instance type.

The ALB was configured for only two Availability Zones.

The Auto Scaling group was configured for only two Availability Zones.

Amazon EC2 Auto Scaling randomly placed the instances in Availability Zones.

Question 60

A company is running a website on Amazon EC2 instances that are in an Auto Scaling group.
