Microsoft Certified: Azure Database Administrator Associate DP-300 Syllabus Exam Questions Answers

Basic Concept: This question tests task automation for database administration, including which Azure or SQL mechanism can run repeatable maintenance and configuration work.

Why B is Correct: Option B is correct because it is the feature whose normal purpose matches the stated requirement. Option B is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario. The scenario wording points to that specific behavior: You need to configure the SQL Server Agent service to email job notifications.

Why A is Wrong: Option A is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario. It applies to a different Azure data-platform design than the one the question is testing.

Why C is Wrong: Option C is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario. It mismatches the target platform, migration method, compute tier, or deployment model described in the scenario, so it would not satisfy the workload as stated.

Why D is Wrong: Option D is an Azure data-platform feature, but it must match the workload model, service tier, migration path, or deployment constraint described in the scenario. It applies to a different Azure data-platform design than the one the question is testing.

The number of files depends on the number of (logical) processors on the machine. As a general rule, if the number of logical processors is less than or equal to eight, use the same number of data files as logical processors. If the number of logical processors is greater than eight, use eight data files and then if contention continues, increase the number of data files by multiples of 4 until the contention is reduced to acceptable levels or make changes to the workload/code.

To get VMs as close as possible, achieving the lowest possible latency, you should deploy them within a proximity placement group.

Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.

Why A is Correct: Create a proximity group and an availability set. Deploy each virtual machine to the availability set Add both virtual machines to the proximity group. is correct because it is the feature whose normal purpose matches the stated requirement. Create a proximity group and an availability set. Deploy each virtual machine to the availability set Add both virtual machines to the proximity group. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. The scenario wording points to that specific behavior: You need to recommend a deployment solution that meets the following requirements: • Provides a Service Level Agreement (SLA) of at least 99.95% • Replicates databases in the same group synchronously • Minimizes the latency of database writes What should you r

Why B is Wrong: Create two proximity groups and a single availability set. Deploy both virtual machines to the availability set. Add one virtual machine to each proximity group. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It handles a different resilience pattern and would not deliver the failover or recovery behavior required here.

Why C is Wrong: Create two proximity groups and two availability sets. Deploy each virtual machine to a unique availability set. Add one virtual machine to each proximity group. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.

Why D is Wrong: Create a proximity group and two availability sets. Deploy each virtual machine to a unique availability set. Add both virtual machines to the proximity group. is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.

Azure Private Link enables you to access Azure PaaS Services (for example, Azure Storage and SQL Database) and Azure hosted customer-owned/partner services over a private endpoint in your virtual network.

Traffic between your virtual network and the service travels the Microsoft backbone network. Exposing your service to the public internet is no longer necessary.
