Essential Free AWS CLF-C01 Exam Dumps & Study Guide

AWS Shield is a managed Distributed Denial of Service (DDoS) protection service. Shield Standard provides automatic protection to all AWS customers at no additional charge.

Security groups act as a firewall at the instance level, and an inbound rule is required to permit specific traffic like SSH (port 22).

The Enterprise Support plan is designed for large-scale deployments and includes a designated Technical Account Manager (TAM) for proactive guidance.

Direct Connect establishes a private, dedicated physical network connection between your data center and an AWS Direct Connect location.

Lifecycle policies allow you to define rules to automatically transition objects to different storage classes or expire them after a specified period.

CloudTrail records user activity and API usage, which allows you to track changes to your AWS resources and troubleshoot operational issues.

Bucket policies are attached directly to S3 buckets and are used to specify what actions are allowed or denied for which principals on the bucket resources.

CodeCommit is a secure, highly scalable, managed source control service that hosts private Git repositories.

Elastic Beanstalk is a PaaS offering that allows you to upload your code, and it automatically handles the deployment, capacity provisioning, load balancing, and auto-scaling.

The AWS Free Tier provides a certain amount of free usage for many AWS services for the first 12 months after opening a new account.

Since AZs are physically separate data centers, deploying across them protects an application from a single point of failure if one AZ becomes unavailable.

This accurately defines an AMI as the blueprint from which new EC2 instances are created.

This is the core function of an Auto Scaling group: ensuring application availability and allowing you to scale EC2 capacity up or down automatically according to conditions you define.

CloudFront is a content delivery network (CDN) that caches data closer to users, which reduces latency and improves performance.

While agility is a benefit of the cloud, ‘Agility and Innovation’ is not one of the official pillars of the framework.

This aligns with the principle of least privilege, protecting the most powerful user in the account from routine exposure.

An Internet Gateway is a horizontally scaled, redundant, and highly available VPC component that enables communication between resources in your VPC and the internet.

Customers are responsible for security ‘in’ the cloud, which includes configuring their own network security controls like security groups and NACLs.

Enabling Multi-AZ automatically provisions and maintains a synchronous standby replica in a different Availability Zone, providing automatic failover.

Redshift is a fast, fully managed data warehouse service that uses columnar storage to efficiently run complex analytic queries against petabytes of structured data.

IaaS provides fundamental building blocks like virtualized compute, network, and storage, upon which you build your own platforms and applications.

AWS Organizations helps you centrally govern your environment as you grow and scale your workloads on AWS, enabling policy-based management and consolidated billing.

Read Replicas are specifically designed to offload read traffic from the primary database instance, allowing you to scale read capacity horizontally.

This is the recommended best practice, as it provides temporary, automatically rotated credentials to the instance, eliminating the need to manage long-term access keys.

A VPC lets you provision a logically isolated section of the AWS Cloud where you can launch AWS resources in a virtual network that you control.

DynamoDB is a fully managed, key-value and document database that delivers single-digit millisecond performance at any scale.

Trusted Advisor acts as an automated expert, providing recommendations across cost optimization, performance, security, fault tolerance, and service limits.

Reserved Instances provide a significant discount over On-Demand pricing in exchange for a commitment to use a specific instance type for a 1 or 3-year term.

S3 stores data as objects within buckets, accessible via an API, which is the definition of object storage.

On-Demand pricing offers flexibility, allowing you to increase or decrease compute capacity depending on your application’s demand without any upfront costs or contracts.

This correctly identifies the core operational difference. Stateless NACLs need explicit rules for both request and response traffic, whereas stateful Security Groups track connections.

An IAM role is an identity with permission policies that determine what the identity can and cannot do in AWS. It is intended to be assumable by anyone who needs it, providing temporary security credentials.

ELB is specifically designed to automatically distribute incoming application traffic across multiple targets, such as EC2 instances, in one or more Availability Zones.

The core value proposition of serverless is that AWS manages the infrastructure, and the service automatically scales to handle the number of incoming requests.

This is the lowest-cost storage class in AWS and is specifically designed for long-term retention (7-10 years) of data that is accessed very infrequently.

CloudWatch Logs is specifically designed to centralize and manage log data from a variety of AWS services and custom applications.

This correctly defines an AWS Region as a physical location in the world which has multiple, physically separate and isolated Availability Zones.

CloudFormation provides a common language for you to model and provision all the infrastructure resources in your cloud environment, following the Infrastructure as Code (IaC) model.

An IAM policy is a JSON document that explicitly lists permissions, defining what actions a principal can or cannot perform on which resources.

This model is a core principle of cloud computing, allowing users to pay for the exact amount of resources they consume without any long-term commitment.

This is a key distinction; security groups have an implicit deny and only support explicit allow rules, whereas NACLs allow for explicit deny rules.
