Section	Objectives	Weight
Domian 1 Monitoring, Logging, and Remediation	1.1 Implement metrics, alarms, and filters by using AWS monitoring and logging services Identify, collect, analyze, and export logs (for example, Amazon CloudWatch Logs, CloudWatch Logs Insights, AWS CloudTrail logs) Collect metrics and logs using the CloudWatch agent Create CloudWatch alarms Create metric filters Create CloudWatch dashboards Configure notifications (for example, Amazon Simple Notification Service [Amazon SNS], Service Quotas, CloudWatch alarms, AWS Health events) 1.2 Remediate issues based on monitoring and availability metrics Troubleshoot or take corrective actions based on notifications and alarms Configure Amazon EventBridge rules to trigger actions Use AWS Systems Manager Automation documents to take action based on AWS Config rules	20%
Domain 2: Reliability and Business Continuity	2.1 Implement scalability and elasticity Create and maintain AWS Auto Scaling plans Implement caching Implement Amazon RDS replicas and Amazon Aurora Replicas Implement loosely coupled architectures Differentiate between horizontal scaling and vertical scaling 2.2 - Implement high availability and resilient environments Configure Elastic Load Balancer and Amazon Route 53 health checks Differentiate between the use of a single Availability Zone and Multi-AZ deployments (for example, Amazon EC2 Auto Scaling groups, Elastic Load Balancing, Amazon FSx, Amazon RDS) Implement fault-tolerant workloads (for example, Amazon Elastic File System [Amazon EFS], Elastic IP addresses) Implement Route 53 routing policies (for example, failover, weighted, latency based) 2.3 - Implement backup and restore strategies Automate snapshots and backups based on use cases (for example, RDS snapshots, AWS Backup, RTO and RPO, Amazon Data Lifecycle Manager, retention policy) Restore databases (for example, point-in-time restore, promote read replica) Implement versioning and lifecycle rules Configure Amazon S3 Cross-Region Replication Execute disaster recovery procedures	16%
Domain 3: Deployment, Provisioning, and Automation	3.1 Provision and maintain cloud resources Create and manage AMIs (for example, EC2 Image Builder) Create, manage, and troubleshoot AWS CloudFormation Provision resources across multiple AWS Regions and accounts (for example, AWS Resource Access Manager, CloudFormation StackSets, IAM cross-account roles) Select deployment scenarios and services (for example, blue/green, rolling, canary) Identify and remediate deployment issues (for example, service quotas, subnet sizing, CloudFormation and AWS OpsWorks errors, permissions) 3.2 Automate manual or repeatable processes Use AWS services (for example, OpsWorks, Systems Manager, CloudFormation) to automate deployment processes Implement automated patch management Schedule automated tasks by using AWS services (for example, EventBridge, AWS Config)	18%
Domain 4: Security and Compliance	4.1 - Implement and manage security and compliance policies Implement IAM features (for example, password policies, MFA, roles, SAML, federated identity, resource policies, policy conditions) Troubleshoot and audit access issues by using AWS services (for example, CloudTrail, IAM Access Analyzer, IAM policy simulator) Validate service control policies and permissions boundaries Review AWS Trusted Advisor security checks Validate AWS Region and service selections based on compliance requirements Implement secure multi-account strategies (for example, AWS Control Tower, AWS Organizations) 4.2 Implement data and infrastructure protection strategies Enforce a data classification scheme Create, manage, and protect encryption keys Implement encryption at rest (for example, AWS Key Management Service [AWS KMS]) Implement encryption in transit (for example, AWS Certificate Manager, VPN) Securely store secrets by using AWS services (for example, AWS Secrets Manager, Systems Manager Parameter Store) Review reports or findings (for example, AWS Security Hub, Amazon GuardDuty, AWS Config, Amazon Inspector)	16%
Domain 5: Networking and Content Delivery	5.1 Implement networking features and connectivity Configure a VPC (for example, subnets, route tables, network ACLs, security groups, NAT gateway, internet gateway) Configure private connectivity (for example, Systems Manager Session Manager, VPC endpoints, VPC peering, VPN) Configure AWS network protection services (for example, AWS WAF, AWS Shield) 5.2 Configure domains, DNS services, and content delivery Configure Route 53 hosted zones and records Implement Route 53 routing policies (for example, geolocation, geoproximity) Configure DNS (for example, Route 53 Resolver) Configure Amazon CloudFront and S3 origin access identity (OAI) Configure S3 static website hosting 5.3 Troubleshoot network connectivity issues Interpret VPC configurations (for example, subnets, route tables, network ACLs, security groups) Collect and interpret logs (for example, VPC Flow Logs, Elastic Load Balancer access logs, AWS WAF web ACL logs, CloudFront logs) Identify and remediate CloudFront caching issues Troubleshoot hybrid and private connectivity issues	18%
Domain 6: Cost and Performance Optimization	6.1 Implement cost optimization strategies Implement cost allocation tags Identify and remediate underutilized or unused resources by using AWS services and tools (for example, Trusted Advisor, AWS Compute Optimizer, Cost Explorer) Configure AWS Budgets and billing alarms Assess resource usage patterns to qualify workloads for EC2 Spot Instances Identify opportunities to use managed services (for example, Amazon RDS, AWS Fargate, EFS) 6.2 Implement performance optimization strategies Recommend compute resources based on performance metrics Monitor Amazon EBS metrics and modify configuration to increase performance efficiency Implement S3 performance features (for example, S3 Transfer Acceleration, multipart uploads) Monitor RDS metrics and modify the configuration to increase performance efficiency (for example, Performance Insights, RDS Proxy) Enable enhanced EC2 capabilities (for example, enhanced network adapter, instance store, placement groups)
