A company needs to launch an Amazon EC2 instance.
Which of the following can the company use during the launch process to configure the root volume of the EC2
instance?

  1. Amazon EC2 Auto Scaling
  2. Amazon Data Lifecycle Manager (Amazon DLM)
  3. Amazon Machine Image (AMI)
  4. Amazon Elastic Block Store (Amazon EBS) volume

Answer(s): C

Explanation:

When launching an Amazon EC2 instance, you can use an Amazon Machine Image (AMI) to configure the root volume. An AMI contains the operating system, application server, and applications required to launch an
EC2 instance, including the configuration for the root volume. The root volume is created from the AMI and is used as the boot disk for the EC2 instance.



A company needs DDoS protection for its AWS resources. The company also needs proactive mitigation assistance from AWS if a DDoS attack occurs.
Which AWS service will meet these requirements?

  1. Amazon GuardDuty
  2. AWS Network Firewall
  3. AWS Shield Advanced
  4. AWS WAF

Answer(s): C

Explanation:

AWS Shield Advanced provides DDoS protection for AWS resources with advanced features such as proactive mitigation assistance, cost protection for scaling during attacks, and 24/7 access to the AWS DDoS Response

Which actions are examples of a company’s effort to rightsize its AWS resources to control cloud costs?
(Choose two.)

  1. Switch from Amazon RDS to Amazon DynamoDB to accommodate NoSQL datasets.
  2. Base the selection of Amazon EC2 instance types on past utilization patterns.
  3. Use Amazon S3 Lifecycle policies to move objects that users access infrequently to lower-cost storage tiers.
  4. Use Multi-AZ deployments for Amazon RDS.
  5. Replace existing Amazon EC2 instances with AWS Elastic Beanstalk.

Answer(s): B,C

Explanation:

Base the selection of Amazon EC2 instance types on past utilization patterns
Right-sizing means choosing instance sizes that match actual CPU, memory, and network usage. Analyzing historical utilization and selecting instance types accordingly prevents over-provisioning.
Use Amazon S3 Lifecycle policies to move objects that users access infrequently to lower-cost storage tiers
By automatically transitioning cold data to cheaper tiers (e.g., S3 Infrequent Access or Glacier), you reduce storage costs without manual intervention.

How does AWS CloudFormation help users operate in the AWS Cloud?

  1. It supports the simple coding of cloud applications.
  2. It monitors the cloud environment.
  3. It automates responses to threats, reducing remediation time and recovery time.
  4. It provides the ability to model and provision the resources that applications need.

Answer(s): D

Explanation:

AWS CloudFormation is a service that enables users to define and provision infrastructure resources in the
AWS Cloud using templates. These templates describe the desired state of AWS resources, and
CloudFormation automates the creation and configuration of those resources, ensuring consistency and reducing manual effort. This allows users to deploy and manage their applications more efficiently by treating infrastructure as code.
