Minhas impressões e material de estudo da prova DP-300 – Administering Relational Databases on Microsoft Azure (beta)

Fala pessoal!
No feriado do dia 01/05, fiz a prova beta “DP-300 – Administering Relational Databases on Microsoft Azure”, que é focada para DBA’s que trabalham ou querem trabalhar com Azure e queria compartilhar minhas impressões sobre a prova e alguns materiais para estudo.

Antes de mais nada, se você quiser dicas de como fazer provas de certificação em casa sem ter muitos problemas, sugiro a leitura do meu post Certificação Microsoft – Dicas de como fazer a prova em casa sem dor de cabeça.

Em geral, achei essa prova difícil, especialmente por não ter estudado e a prova ter um conteúdo bem abrangente, especialmente nas comparações entre Azure SQL Database e o Azure Managed Instance, que não estou tão habituado de trabalhar, especialmente comparando preços entre os 2 e também em diversos cenários de migração entre On-Premises para Azure.

Material de estudo da prova DP-300 (Administering Relational Databases on Microsoft Azure)

Como essa prova ainda está em fase beta, a página do Learning Path dessa prova ainda não está disponível, ou seja, não tem material oficial pra estudo (como toda prova beta).

Material de estudo de acordo com o que eu lembro da prova

Vou destacar o que eu lembro que caiu na prova pra tentar direcionar o estudo de vocês, lembrando que existem várias variações da prova e nem sempre serão as mesmas questões:

• Cenários ideais para uso do elastic pool
• Estudem bastante a parte de Configuração de AlwaysOn em máquinas virtuais (Link aqui)
• Segurança do Azure SQL Database
• Criação de logins no Azure SQL Database usando autenticação Azure Active Directory
• Roles do Azure SQL Database
• Execução de backup em réplica secundária de AlwaysOn (Link aqui)
• DMV’s para fazer um troubleshooting de performance e locks em Azure SQL Database
• Cenários de Alta Disponibilidade entre Azure SQL Database e Azure Managed Instance com Leitura Habilitada na Réplica (preste atenção em custo e tiers Premium)
• Criação de conexão entre Azure SQL Database e Azure VM usando VPN, Endpoints ou Service Points
• Cenários de Replicação vs Failover Cluster com Automatic Failover: Qual o melhor cenário para cada
• Dynamic Data Masking (Link aqui)
• Criptografia de Colunas – Link aqui
• Transparent Data Encryption (TDE) – Link aqui
• Automatic Tuning
• Query Store
• Azure Managed Instance
• Criação de Backup do Azure Managed Instance
• Azure Site Recovery
• Redundância de Storage
• Muitos cenários de migração de On-premise para Azure SQL Database, Managed Instance e VM usando SSMS, PowerShell (Link aqui e veja os outros tutoriais)
• MySQL e Postgres rodando no Azure como PaaS (Link aqui)
• Azure Database Migration Service
• Alertas e notificações do SQL Server Agent
• Redução de contenção de tempdb

Material de estudo de acordo com a página da Microsoft sobre a prova

Também estou disponibilizando um grande trabalho feito pelo também MVP, Gregor Suttie, que compilou essa coletânea de links para ajudar nos estudos nessa prova e que estou compartilhando de forma a ficar no meu padrão de estilo de artigo:
