Answer

Savings Plans 1.00 / 1

The correct response option is Savings Plans. Amazon EC2 Savings Plans enable you to reduce your compute costs by committing to a consistent amount of compute usage for a 1-year or 3-year term. This results in savings of up to 72% over On-Demand Instance costs. Any usage up to the commitment is charged at the discounted Savings Plan rate (for example, $10 an hour). Any usage beyond the commitment is charged at regular On-Demand Instance rates. The other response options are incorrect because: Reserved Instances are a billing discount that is applied to the use of On-Demand Instances in your account. You can purchase Standard Reserved and Convertible Reserved Instances for a one-year or three-year term, and Scheduled Reserved Instances for a one-year term. Unlike Savings Plans, Reserved Instances do not require you to commit to a consistent amount of compute usage over the duration of the contract. Spot Instances are ideal for workloads with flexible start and end times or that can withstand interruptions. Spot Instances leverage unused EC2 computing capacity and offer you cost savings at up to 90% of On-Demand Instance prices. Dedicated Hosts are physical servers with EC2 instance capacity that is fully dedicated to your use. You can use your existing per-socket, per-core, or per-VM software licenses to help maintain license compliance. You can purchase On-Demand Dedicated Hosts or Reserved Dedicated Hosts. Of all the Amazon EC2 options that were covered in this course, Dedicated Hosts are the most expensive.

AWS Organizations 1.00 / 1

The correct response option is AWS Organizations. In AWS Organizations, you can centrally control permissions for the accounts in your organization by using service control policies (SCPs). Additionally, you can use the consolidated billing feature in AWS Organizations to combine usage and receive a single bill for multiple AWS accounts. The other response options are incorrect because: AWS Identity and Access Management (IAM) is a service that you can use to manage access to AWS services and resources. AWS Artifact is a service that enables you to access AWS security and compliance reports and special online agreements. AWS Key Management Service (AWS KMS) enables you to create, manage, and use cryptographic keys.

[https://aws.amazon.com/organizations/: https://aws.amazon.com/organizations/] Deliver content to customers through a global network of edge locations. 1.00 / 1

The correct response is Deliver content to customers through a global network of edge locations. Amazon CloudFront is a content delivery service. It uses a network of edge locations to cache content and deliver content to customers all over the world. When content is cached, it is stored locally as a copy. This content might be video files, photos, webpages, and so on. The other response options are incorrect because: Run infrastructure in a hybrid cloud approach - This action can be performed with AWS Outposts. Provision resources by using programming languages or a text file - This action can be performed in AWS CloudFormation. Provision an isolated section of the AWS Cloud to launch resources in a virtual network that you define - This action can be performed in Amazon Virtual Private Cloud (Amazon VPC).

[**Amazon CloudFront: https://aws.amazon.com/cloudfront/] Performance Efficiency 1.00 / 1**

The correct response option is Performance Efficiency.

The correct response option is A service that distributes incoming traffic across multiple targets, such as Amazon EC2 instances. A load balancer acts as a single point of contact for all incoming web traffic to your Auto Scaling group. This means that as Amazon EC2 instances are added or removed in response to the amount of incoming traffic, these requests are routed to the load balancer first and then spread across multiple resources that will handle them. The other response options are incorrect because: A service that monitors your applications and automatically adds or removes capacity from your resource groups in response to changing demand - This response option describes AWS Auto Scaling. A service that provides data that you can use to monitor your applications, optimize resource utilization, and respond to system-wide performance changes - This response option describes Amazon CloudWatch.

[AWS Command Line Interface: https://aws.amazon.com/cli/] Security group 1.00 / 1

The correct response option is security group. A security group is a virtual firewall that controls inbound and outbound traffic for an Amazon EC2 instance. By default, a security group denies all inbound traffic and allows all outbound traffic. You can add custom rules to configure which traffic should be allowed or denied. The other response options are incorrect because: A subnet is a section of a VPC in which you can group resources based on security or operational needs. A network access control list (ACL) is a virtual firewall that controls inbound and outbound traffic at the subnet level. An internet gateway is a connection between a VPC and the internet.
