Domain weightings

How much of the exam each domain covers. Spend your study time in proportion — the heavier the domain, the more questions you'll see.

Key terms

Amazon CloudWatch
Amazon CloudWatch is a monitoring service that collects metrics, logs, and alarms for AWS resources and applications. SOA-C03 covers it as the core of the monitoring, logging, analysis, and remediation domain.
CloudWatch Alarm
A CloudWatch alarm is a rule that watches a metric and triggers actions — notifications, Auto Scaling, or automated remediation — when a threshold is breached. SOA-C03 covers alarms for remediation and reliability.
Amazon EventBridge
Amazon EventBridge is an event bus that routes events between AWS services and triggers targets such as Lambda for automated responses. SOA-C03 covers it for event-driven remediation and automation.
EC2 Auto Scaling
EC2 Auto Scaling is a service that automatically adjusts the number of EC2 instances using launch templates and scaling policies. SOA-C03 covers it for scalability and reliability in the business-continuity domain.
Multi-AZ Deployment
A Multi-AZ deployment runs resources across multiple Availability Zones so a workload survives the failure of one zone. SOA-C03 covers it for high availability and reliability.
AWS Backup
AWS Backup is a centralized service for automating and managing backups across AWS services with policy-based schedules. SOA-C03 covers it for backup, restore, and disaster recovery to meet RTO and RPO.
Amazon EBS
Amazon EBS (Elastic Block Store) is a service that provides persistent block storage volumes for EC2 instances, with snapshots for backup. SOA-C03 covers EBS volumes and snapshots in backup and reliability scenarios.
AWS CloudFormation
AWS CloudFormation is an infrastructure-as-code service that provisions AWS resources from templates, with stacks, stack sets, and drift detection. SOA-C03 covers it in the deployment, provisioning, and automation domain.
AWS Systems Manager
AWS Systems Manager is a service for operational management — Automation, Run Command, State Manager, Patch Manager, and Parameter Store. SOA-C03 covers it for automating repeatable operations.
AWS KMS
AWS Key Management Service (KMS) is a managed service that creates and controls the cryptographic keys used to encrypt data. SOA-C03 covers it for data protection in the security and compliance domain.
AWS Config
AWS Config records resource configurations and evaluates them against rules for compliance. SOA-C03 covers it, with CloudTrail and Security Hub, for compliance auditing in the security and compliance domain.
Security Group
A security group is a stateful virtual firewall that controls inbound and outbound traffic for AWS resources such as EC2 instances. SOA-C03 covers security groups and NACLs in the networking and content delivery domain.
Amazon Route 53
Amazon Route 53 is AWS's scalable DNS and domain service with routing policies and health checks. SOA-C03 covers it for DNS, routing, and health-check-based availability in the networking domain.
VPC Flow Logs
VPC Flow Logs capture metadata about IP traffic to and from network interfaces in a VPC. SOA-C03 covers them for troubleshooting connectivity and monitoring network traffic.
