Amazon Cloud Practitioner Exam Study Guide
Questions and Answers 100% Pass
Amazon DynamoDB - ✔✔A key-value and document database that delivers single digit millisecond
performance at any scale. It's a fully managed, multiregion, multimaster database with built-in security,
backup and restore, and in-memory caching for internet-scale applications. Non-relational database that
is serverless with a flexible data model
Software Development Kit - ✔✔Tools that allow the creation of products or add-ons for a specific
operating system or other computing platform. Available in Javascript, Java and PHP
Elastic Cloud Compute (EC2) - ✔✔A web service that provides secure, resizable compute capacity in the
cloud. It is designed to make web-scale cloud computing easier for developers. Can host databases as
well. EC2 instances will automatically launch into the Region you currently have selected. Instance type
families are compute optimized and accelerated computing
Amazon Machine Image (AMI) - ✔✔The software configuration required to launch your instance. It must
include the following:
One or more EBS snapshots, or a template for the root volume of the instance (for example, an operating
system, an application server, and applications).
Launch permissions that control which AWS accounts can launch instances.
A block device mapping that specifies the volumes to attach to the instance when it's launched.

,Amazon Elastic Block Store (Amazon EBS) - ✔✔An easy to use, high performance storage service
designed for use with Amazon Elastic Compute Cloud (EC2) for both throughput and transaction
intensive workloads at any scale. Can host databases as well. The data in an instance store persists only
during the lifetime of its associated instance. If an instance reboots (intentionally or unintentionally), data
in the instance store persists.
Block Storage - ✔✔An approach to data storage in which each storage volume acts as an individual hard
drive that is configured by the storage administrator. In this model, data is saved to the storage media in
fixed-sized chunks called blocks.
Amazon Simple Storage Service (S3) - ✔✔An object storage service that offers industry-leading
scalability, data availability, security, and performance. Information stored is not specifically assigned to
a particular server. STANDARD_IA and GLACIER storage classes offer the highest levels of redundancy
and are replicated across at least three Availability Zones. Object life cycle configurations can perform
transition or expiration actions based on an object's age. You can use bucket policies or access control lists
(ACLs) to grant anonymous users access to an object in S3.
Object Storage - ✔✔Objects (files) are stored with additional metadata (content type, redundancy
required, creation date, etc.). These objects are accessible through APIs and potentially through a web
user interface.
AWS Global Infrastructure - ✔✔It is built around Regions and Availability Zones (AZs). In total, the
AWS Cloud operates 69 Availability Zones within 22 geographic Regions around the world.
Availability Zone (AZ) - ✔✔Consist of one or more discrete data centers, each with redundant power and
networking, housed in separate facilities. Each one is connected via a secure network connection.
Isolation protects them from failure. Each region has at least 2
Edge Location - ✔✔Host a content delivery network to deliver content to the customers through Amazon
CloudFront

, Amazon Virtual Private Cloud (VPC) - ✔✔A private network in the AWS Cloud. Allows complex control
of network configuration and offers several layers of security controls. For each account, AWS creates a
default in each Region that spans all Availability Zones within a Region.
Subnets - ✔✔A logically visible subdivision of an Internet Protocol (IP) network. The block of IP
addresses assigned for use within a single Availability Zone. Used to divide Amazon VPCs allowing
them to span multiple AZs. It must have a CIDR that's a subset of CIDR of the VPC in which it resides.
Internet Gateway - ✔✔Is a gateway that allows you to have internet access to your VPCs
NAT Gateway - ✔✔Allows private subnet resources to access the Internet
Network Access Control Lists (NACL) - ✔✔Controls access to subnets, stateless
AWS Security Groups - ✔✔Act like a firewall for your Amazon EC2 instances controlling both inbound
and outbound traffic. IP address 0.0.0.0/0 represents any and all internet traffic. Contains an outbound
rule that allows access to any IP address by default. It doesn't contain an inbound rule by default. Rules
can only permit access, not deny it, so any traffic not explicitly allowed will be denied.
Application Load Balancer - ✔✔Operating at the request level, they provide advanced routing, TLS
termination and visibility features targeted at application architectures, including microservices and
containers. Also uses health checks to identify failed instances and remove them from load balancing.
Can now support invoking Lambda functions to serve HTTP requests.
Listeners - ✔✔Check for connection requests using the protocol and port that you configure. Rules you
define determine how the load balancer routes requests
Target - ✔✔Destination for traffic based on the established listener rules
