Answer 1

AWS Organizations

Answer 2

Amazon EventBridge

Answer 3

AWS Budgets

Answer 4

AWS Elastic Beanstalk

Answer 5

AWS Secrets Manager

Answer 6

VPC Flow Logs

Answer 7

- otimo para microsserviços, jobs, funções isoladas - quando usar? - lógicas pequenas ou médias em resposta a eventos - apis rests - eventos agnósticos

Answer 8

- cria API pública ou privada sem precisar gerenciar webservers - gerencia e expõe endpoints HTTP de forma escalável

Answer 9

A service to manage user identities and access to AWS resources

Answer 10

A virtual private network to control AWS networking.

Answer 11

Persistent block storage for use with EC2 instances

Answer 12

A scalable and fully managed file storage service for use with Amazon EC2. It allows multiple instances to share data concurrently, just like a network file system. Storage grows and shrinks automatically as files are added or removed, and it’s ideal for use cases like content management, web serving, and data sharing across instances. A web application hosted on multiple EC2 instances needs to access and update the same set of files (e.g., images, configuration files, or logs). It allows all instances to read from and write to the same file system simultaneously, ensuring consistency and simplifying file management.

Answer 13

are stateless firewalls applied at the subnet level to control the flow of traffic into and out of a subnet. operate at the subnet level and allow you to control inbound and outbound traffic to and from that subnet.

Answer 14

A logical subdivision within a virtual network that helps organize and isolate resources. It allows you to control how traffic flows, and whether resources are accessible publicly (through the internet) or privately (only within the internal network). Use Case: Placing a database in an isolated environment with no internet access while allowing web servers to be in a zone that can receive public traffic — separating resources for better security and traffic control.

Answer 15

automatically distributes incoming application traffic across multiple EC2 instances, improving availability and fault tolerance.

Answer 16

refers to the capability to dynamically adjust resource allocation based on demand and to quickly obtain resources when necessary.

Answer 17

The ability of a system to handle an increasing workload by adding resources. It can be achieved by upgrading the capacity of existing components (vertical) or by adding more components (horizontal), ensuring consistent performance as demand grows over time.

Answer 18

Definition

Answer 19

The ability of cloud resources to automatically adjust capacity up or down according to workload demands.

Answer 20

Refers to the capability to increase the resources or size of your infrastructure to handle growth in demand.

Answer 21

Ensures that systems and applications are continuously operational and accessible even during failures.

Answer 22

Describes a system's ability to remain functional even when some components fail.

Answer 23

Security is shared between AWS and the customer: AWS protects the infrastructure, while customers manage their data and configurations.

Answer 24

A pricing model where you only pay for what you use, with no upfront fees or long-term commitments.

Answer 25

Used to run virtual machines in the cloud with full control over the operating system and networking.

Answer 26

Provides scalable object storage used for backups, data lakes, and static website hosting.

Answer 27

Executes code in response to events without provisioning or managing servers, making it ideal for short-lived tasks.

Answer 28

Manages relational databases by handling backups, patching, and scaling without user intervention.

Answer 29

A fully managed NoSQL database known for single-digit millisecond response times and automatic scaling.

Answer 30

Enables you to define a virtual network isolated from other AWS users, where you can launch AWS resources.

Answer 31

Manages access to AWS services and resources securely using roles, policies, and permissions.

Answer 32

Delivers content with low latency by caching it at edge locations near users.

Answer 33

Provides block-level storage volumes that persist beyond the life of EC2 instances.

Answer 34

Offers scalable file storage for use with Amazon EC2 that grows and shrinks automatically.

Answer 35

Protects applications against common DDoS attacks with always-on detection and automatic inline mitigations.

Answer 36

Filters and blocks malicious HTTP/S traffic based on customizable web security rules.

Answer 37

Records account activity and API calls for auditing, compliance, and governance.

Answer 38

Continuously monitors and records AWS resource configurations to assess compliance over time.

Answer 39

Users and systems should only be granted the permissions absolutely necessary to perform their tasks.

Answer 40

Lets you pay for compute capacity by the second or hour with no upfront payment or long-term commitment.

Answer 41

Provides significant cost savings when you commit to using EC2 instances for a one- or three-year term.

Answer 42

Allows you to bid on unused EC2 capacity at steep discounts, suitable for flexible and interruption-tolerant workloads.

Answer 43

A program that offers limited use of AWS services for free for 12 months to help new users get started.

Answer 44

Combines billing for multiple AWS accounts, allowing for easier cost tracking and volume discounts.

Answer 45

An online tool to estimate the monthly cost of AWS resources based on your expected usage.

Answer 46

A geographical area composed of multiple isolated data centers, enabling you to deploy resources closer to users.

Answer 47

A data center or group of data centers within a region, isolated for fault tolerance yet connected for performance.

Answer 48

Part of AWS's global network for delivering content and services with reduced latency to end users.

Answer 49

Automatically adjusts compute capacity to meet real-time demand without manual intervention.

Answer 50

Distributes incoming application traffic across multiple targets, increasing fault tolerance and availability.

Answer 51

provides on-demand access to AWS compliance documentation, including audit reports and security certifications needed for PCI compliance. allowing customers to download and review them as needed.
