Questions with Verified Correct Answers
Dedicated Hosts
Physical servers with Amazon EC2 instance capacity that is fully dedicated to your use.
AWS Lambda
Server-less and lets you run code without provisioning or managing servers. You pay only for
the compute time you consume—there is no charge when your code is not running. Not good
for hosting legacy applications.
AWS CodePipeline
Automates the code release lifecycle.
AWS CodeDeploy
Deploys code from a repository and installs the application.
Tags
Can be assigned to individual EC2 instances to easily identify them on a cost allocation
report or for other metrics. For example the tags could be assigned to different departments
within an organization to identify the costs of each department.
AWS CloudTrail
Used for auditing your account. Provides visibility into user activity by recording API calls
made on your account.
AWS CloudFormation
,Gives developers and systems administrators an easy way to create and manage a collection
of related AWS resources, provisioning and updating them in an orderly and predictable
fashion.
Amazon CloudWatch
A performance monitoring and resource utilization service. Provides operational
performance, log aggregation, hooks to event triggers real-time, metrics, alarms,
notifications, and custom metrics.
Amazon CloudFront
A content delivery network (CDN). Provides lower latency due to caching content closer to
your users, and improves performance as a result.
AWS Trusted Advisor
Used to assist with guidance on provisioning resources according to best practice. Inspects
your AWS environment and makes recommendations when opportunities may exist to save
money, improve system performance or close security gaps.
AMI - Amazon Machine Image

AWS Well-Architected Framework
1. Operational Excellence
2. Security
3. Reliability
4. Performance Efficiency

, Amazon Redshift
Data Warehousing service
EC2 Instance Types
1. General purpose instances
2. Compute optimized instances
3. Memory optimized instances
4. Accelerated computing instances

Dedicated Host
- Isolated physical server
- Most expensive purchase type
- Good if you have per server license
- Most customization and control over resources
Dedicated Instance
EC2 instances that are physically isolated at the hardware level. Less customization and
control over resources than a dedicated host.
AWS Systems Manager
Used for managing EC2 instances and installing patches or software. Service that provides a
collection of tools and insight into operational data for managing and automating tasks.
AWS Artifact
Central resource for compliance-related information that matters to you. It provides on-
