SOA-C02 Practice Test

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 user has not properly configured the AWS CLI with their access key and secret access key.

B.

The SysOps administrator does not have the necessary permissions to upload the object to the S3 bucket.

C.

The SysOps administrator must apply a bucket policy to the S3 bucket to allow the user to upload the object.

D.

The object already has been uploaded through the use of the presigned URL, so the presigned URL is no longer valid.

A new website will run on Amazon EC2 instances behind an Application Load Balancer. Amazon Route 53 will be used to manage DNS records.
What type of record should be set in Route 53 to point the website’s apex domain name (for example.company.com to the Application Load Balancer?

A.

CNAME

B.

SOA

C.

TXT

D.

ALIAS

A company hosts a website on multiple Amazon EC2 instances that run in an Auto Scaling
group. Users are reporting slow responses during peak times between
6 PM and 11 PM every weekend. A SysOps administrator must implement a solution to
improve performance during these peak times.
What is the MOST operationally efficient solution that meets these requirements?

A.

Create a scheduled Amazon EventBridge (Amazon CloudWatch Events) rule to invoke an AWS Lambda function to increase the desired capacity before peak times.

B.

Configure a scheduled scaling action with a recurrence option to change the desired capacity before and after peak times.

C.

Create a target tracking scaling policy to add more instances when memory utilization is above 70%.

D.

Configure the cooldown period for the Auto Scaling group to modify desired capacity before and after peak times.

A data storage company provides a service that gives users the ability to upload and
download files as needed. The files are stored in Amazon S3 Standard and must be
immediately retrievable for 1 year. Users access files frequently during the first 30 days
after the files are stored. Users rarely access files after 30 days.
The company's SysOps administrator must use S3 Lifecycle policies to implement a
solution that maintains object availability and minimizes cost.
Which solution will meet these requirements?

A.

Move objects to S3 Glacier after 30 days.

B.

Move objects to S3 One Zone-Infrequent Access (S3 One Zone-IA) after 30 days.

C.

Move objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days.

D.

Move objects to S3 Standard-Infrequent Access (S3 Standard-IA) immediately.

A SysOps administrator has an AWS CloudFormation template of the company's existing infrastructure in us-west-2. The administrator attempts to use the template to launch a newstack in eu-west-1, but the stack only partially deploys, receives an error message, and then rolls back. Why would this template fail to deploy? (Select TWO.)

A.

The template referenced an IAM user that is not available in eu-west-1. B. The template referenced an Amazon Machine Image (AMI) that is not available in eu-west-1.

B.

The template did not have the proper level of permissions to deploy the resources.

C.

The template requested services that do not exist in eu-west-1.

D.

CloudFormation templates can be used only to update existing services.
