[EXAM REVIEWER] AWS Certified Cloud Practitioner CLF-C02

Explore the benefits of the AWS cloud, including reduced capital costs, managed infrastructure, elasticity, and global deployment. See how auto scaling and CloudWatch monitoring optimize performance and cost.

Explore cloud advantages like operating costs over capital costs, economies of scale, and rapid speed and agility, and compare pay as you go public cloud with on-premise CapEx and OpEx.

Explore how cloud cost advantages arise from fine-grained billing, on-demand usage, and the ability to turn off resources, plus elasticity and reserved instances for savings.

Discover why moving from on premises to AWS enables easier right sizing and agile, elastic scaling, while noting you retain security responsibilities and limited end-to-end control.

Explore how to choose AWS regions based on data sovereignty and latency, recognizing that regions contain multiple availability zones and that global infrastructure is region-based.

Explore the AWS global infrastructure, including regions, availability zones, data centers, edge locations, and the global network, and learn how fault isolation and low latency connections support reliable, scalable deployments.

Identify which AWS services are regional versus global, noting EC2 and S3 are regional while CloudFront, Route 53, and IAM are global, with S3 data stored regionally.

Master the AWS shared responsibility model, where AWS secures the cloud and customers ensure data protection, encryption, OS patching, IAM, and security groups.

Explore the AWS shared responsibility model, distinguishing security in the cloud for the customer from security of the cloud handled by AWS, with patch management as a key shared control.

Identify which actions fall to AWS versus customers in the AWS shared responsibility model, including encryption, patching, security groups, and S3 bucket policies.

Clarifies AWS shared responsibility model, highlighting customer duties for network configuration, security groups, network ACLs, WAF, and data in transit encryption, and identifies awareness and training as a shared control.

Learn how auto scaling automatically adjusts compute capacity as load changes. Compare load balancing, automatic failover, and round robin, and explore reserved instances for cost savings and capacity reservation.

Explore how scheduled reserved instances match capacity to predictable daily, weekly, or monthly usage, and compare standard and convertible options, plus how tagging EC2 instances allocates metadata.

Determine the best EC2 pricing model for a continuously running production process by selecting reserved instances. Learn how Elastic Beanstalk handles deployment and how Lambda provides serverless, event-driven code execution.

Explore Amazon S3 cross region replication, versioning, and static website hosting, while grasping transfer acceleration and related S3 features for secure, scalable storage.

Assess cost-effective S3 tiers for data not often accessed but highly available. Compare storage gateway options for backups, including virtual tape library, and EFS for NFS mounts on EC2.

Identify buckets as containers and objects as data in Amazon S3, an object-based storage accessed via URLs and REST APIs. Objects include key-value data, version IDs, metadata, and access control.

Explain how Amazon S3 object lifecycle management automatically moves data between storage classes and archives or deletes objects, and how cross-region replication protects data during regional failures.

Explore how API Gateway uses CloudFront edge optimized endpoint to lower latency for API requests around the world, and how Route 53 supports DNS routing and health checks.

Explain the scope of a vpc within a region, including cidr blocks, subnets, and availability zones, and how direct connect gateway enables on-premises access to vpcs across multiple regions.

Explore which AWS services use edge locations, notably CloudFront and Shield, and compare options like Direct Connect, VPN CloudHub, and VPC endpoints for private, global connectivity and improved performance.

Compare relational and non-relational databases, including RDS and Aurora, and understand SQL and flexible schemas. Discover horizontal versus vertical scaling, read replicas, and NoSQL types like DynamoDB, Reddis, and Neptune.

Learn to manage RDS patching and automated backups with maintenance windows and point-in-time recovery, and identify graph databases like Neptune.

Explains how Multi-AZ RDS provides fault tolerance with automatic failover to a standby in another availability zone. Covers DynamoDB accelerator (DAX) as an in-memory speedup for DynamoDB.

Explore how RDS automated backups support five-minute point-in-time restores with transaction logs and snapshots, and compare cloud advantages like scalability, high availability, and DynamoDB's schemaless scaling.

Migrate the MySQL database to Amazon RDS to reduce operational overhead, a managed service, and scale by instance size or storage, using read replicas for reads.

Explore management and governance through practice questions on AWS services like CloudFormation and OpsWorks for infrastructure automation, AWS Organizations for account creation, and QuickStart reference deployments for rapid IT solutions.

Discover how AWS Organizations uses service control policies to restrict access across member accounts and resources, and explore Trusted Advisor's real-time guidance on cost, performance, security, and fault tolerance.

Learn how to monitor and troubleshoot using CloudWatch logs and dashboards, distinguish CloudWatch metrics from CloudTrail activity, and leverage Systems Manager with CloudFormation and Beanstalk to automate AWS operations.

Explore AWS security and compliance reports on demand with Artifact, and compare DDoS protection and programmatic access using access keys.

Apply AWS WAF with CloudFront and Firewall Manager to block malicious web traffic, and use Macie to detect PII data in S3, while configuring security groups for instance-level firewalls.

Learn how to use GuardDuty for threat detection and monitoring of unauthorized behavior, analyzing CloudTrail logs, VPC flow logs, and DNS logs with machine learning to automate responses.

Group users to assign permissions by job role, attaching policy to the group; use roles to delegate permissions to services like Lambda or EC2, enabling temporary credentials without embedded keys.
