PANORAMICA

Certificazione AWS Certified Database – Specialty - Planning and Designing Databases on AWS

Esame AWS Certified Database – Specialty;

 

The AWS Certified Database – Specialty (DBS-C01) exam is intended for individuals who perform a database-focused role. This exam validates a candidate’s comprehensive understanding of databases, including the concepts of design, migration, deployment, access, maintenance, automation, monitoring, security, and troubleshooting.

The exam also validates a candidate’s ability to complete the following tasks:

  • Understand and differentiate the key features of AWS database services
  • Analyze needs and requirements to design and recommend appropriate database solutions by using AWS services

Per conseguire la Certificazione AWS Certified Database – Specialty è necessario sostenere con successo il seguente esame:
AWS DBS-C01;

ARGOMENTI D’ESAME

Esame AWS Certified Database – Specialty – DBS-C01

Domain 1: Workload-Specific Database Design

  • Select appropriate database services for specific types of data and workloads.
  • Differentiate between ACID vs. BASE workloads
  • Explain appropriate uses of types of databases (e.g., relational, key-value, document, in-memory, graph, time series, ledger)
  • Identify use cases for persisted data vs. ephemeral data
  • Determine strategies for disaster recovery and high availability.
  • Select Region and Availability Zone placement to optimize database performance
  • Determine implications of Regions and Availability Zones on disaster recovery/high availability strategies
  • Differentiate use cases for read replicas and Multi-AZ deployments
  • Design database solutions for performance, compliance, and scalability.
  • Recommend serverless vs. instance-based database architecture
  • Evaluate requirements for scaling read replicas
  • Define database caching solutions
  • Evaluate the implications of partitioning, sharding, and indexing
  • Determine appropriate instance types and storage options
  • Determine auto-scaling capabilities for relational and NoSQL databases
  • Determine the implications of Amazon DynamoDB adaptive capacity
  • Determine data locality based on compliance requirements
  • Compare the costs of database solutions.
  • Determine cost implications of Amazon DynamoDB capacity units, including on-demand vs. provisioned capacity
  • Determine costs associated with instance types and automatic scaling
  • Design for costs including high availability, backups, multi-Region, Multi-AZ, and storage type options
  • Compare data access costs

 

Domain 2: Deployment and Migration

  • Automate database solution deployments.
  • Evaluate application requirements to determine components to deploy
  • Choose appropriate deployment tools and services (e.g., AWS CloudFormation, AWS CLI)
  • Determine data preparation and migration strategies.
  • Determine the data migration method (e.g., snapshots, replication, restore)
  • Evaluate database migration tools and services (e.g., AWS DMS, native database tools)
  • Prepare data sources and targets
  • Determine schema conversion methods (e.g., AWS Schema Conversion Tool)
  • Determine heterogeneous vs. homogeneous migration strategies
  • Execute and validate data migration.
  • Design and script data migration
  • Run data extraction and migration scripts
  • Verify the successful load of data

 

Domain 3: Management and Operations

  • Determine maintenance tasks and processes.
  • Account for the AWS shared responsibility model for database services
  • Determine appropriate maintenance window strategies
  • Differentiate between major and minor engine upgrades
  • Determine backup and restore strategies.
  • Identify the need for automatic and manual backups/snapshots
  • Differentiate backup and restore strategies (e.g., full backup, point-in-time, encrypting backups cross-Region)
  • Define retention policies
  • Correlate the backup and restore to recovery point objective (RPO) and recovery time objective
  • (RTO) requirements
  • Manage the operational environment of a database solution.
  • Orchestrate the refresh of lower environments
  • Implement configuration changes (e.g., in Amazon RDS option/parameter groups or Amazon
  • DynamoDB indexing changes)
  • Automate operational tasks
  • Take action based on AWS Trusted Advisor reports
  • Domain 4: Monitoring and Troubleshooting
  • Determine monitoring and alerting strategies.
  • Evaluate monitoring tools (e.g., Amazon CloudWatch, Amazon RDS Performance Insights, database native)
  • Determine appropriate parameters and thresholds for alert conditions
  • Use tools to notify users when thresholds are breached (e.g., Amazon SNS, Amazon SQS,
  • Amazon CloudWatch dashboards)
  • Troubleshoot and resolve common database issues.
  • Identify, evaluate, and respond to categories of failures (e.g., troubleshoot connectivity; instance, storage, and partitioning issues)
  • Automate responses when possible
  • Optimize database performance.
  • Troubleshoot database performance issues
  • Identify appropriate AWS tools and services for database optimization
  • Evaluate the configuration, schema design, queries, and infrastructure to improve performance

 

Domain 5: Database Security

  • Encrypt data at rest and in transit.
  • Encrypt data in relational and NoSQL databases
  • Apply SSL connectivity to databases
  • Implement key management (e.g., AWS KMS, AWS CloudHSM)
  • Evaluate auditing solutions.
  • Determine auditing strategies for structural/schema changes (e.g., DDL)
  • Determine auditing strategies for data changes (e.g., DML)
  • Determine auditing strategies for data access (e.g., queries)
