A company's SysOps administrator deploys a public Network Load Balancer (NLB) in front of the company's web application. The web application does not use any Elastic IP addresses. Users must access the web application by using the company's domain name. The SysOps administrator needs to configure Amazon Route 53 to route traffic to the NLB.
Which solution will meet these requirements MOST cost-effectively?

1. A. Create a Route 53 AAAA record for the NLB.
2. B. Create a Route 53 alias record for the NLB.
3. C. Create a Route 53 CAA record for the NLB.
4. D. Create a Route 53 CNAME record for the NLB.

A SysOps administrator creates an AWS CloudFormation template to define an application stack that can be deployed in multiple AWS Regions.
The SysOps administrator also creates an Amazon CloudWatch dashboard by using the AWS Management Console. Each deployment of the application requires its own CloudWatch dashboard.
How can the SysOps administrator automate the creation of the CloudWatch dashboard each time the application is deployed?

1. A. Create a script by using the AWS CLI to run the aws cloudformation put-dashboard command with the name of the dashboar
2. B. Run the command each time a new CloudFormation stack is created.
3. C. Export the existing CloudWatch dashboard as JSO
4. D. Update the CloudFormation template to define an AWS::CloudWatch::Dashboard resourc
5. E. Include the exported JSON in the resource's DashboardBody property.
6. F. Update the CloudFormation template to define an resourc
7. G. Use the intrinsic Ref function to reference the ID of the existing CloudWatch dashboard.
8. H. Update the CloudFormation template to define an AWS::CloudWatch::Dashboard resourc
9. I. Specify the name of the existingdashboard in the DashboardName property.

Correct Answer: B
You can only use the Intrinsic Ref function to reference a resource that is being created at the same time as the current CloudFormation template. The question states that the CloudWatch dashboard was previously created using the AWS Management Console, so there is no ID to reference the existing CloudWatch dashboard in the CloudFormation template. You would need to export the existing CloudWatch dashboard as JSON, then use the DashboardBody property in the CloudFormation template to replicate it upon each deployment

A company needs to take an inventory of applications that are running on multiple Amazon EC2 instances. The company has configured users and roles with the appropriate permissions for AWS Systems Manager. An updated version of Systems Manager Agent has been installed and is running on every instance. While configuring an inventory collection, a SysOps administrator discovers that not all the instances in a single subnet are managed by Systems Manager.
What must the SysOps administrator do to fix this issue?

1. A. Ensure that all the EC2 instances have the correct tags for Systems Manager access.
2. B. Configure AWS Identity and Access Management Access Analyzer to determine and automatically remediate the issue.
3. C. Ensure that all the EC2 instances have an instance profile with Systems Manager access.
4. D. Configure Systems Manager to use an interface VPC endpoint.

Correct Answer: C
Ensuring that all the EC2 instances have an instance profile with Systems Manager access is the most effective way to fix this issue. Having an instance profile with Systems Manager access will allow the SysOps administrator to configure the inventory collection for all the instances in the subnet, regardless of whether or not they are managed by Systems Manager.
