NEW QUESTION # 184
You have an Azure subscription that contains two instances of SQL Server on Azure Virtual Machines named VM1 and VM2. Both instances run Microsoft SQL Server 2019 CU8. You need to deploy a failover cluster instance (FCI) to VM1 and VM2. The solution must eliminate the need for the following:
* A distributed network name (DNN)
* A load balancer
What should you do?
Answer: B
Explanation:
Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
Why D is Correct: Connect VM1 and VM2 to different subnets on a single virtual network. is correct because it is the feature whose normal purpose matches the stated requirement. Connect VM1 and VM2 to different subnets on a single virtual network. 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 deploy a failover cluster instance (FCI) to VM1 and VM2.
Why A is Wrong: Deploy VM1 and VM2 to a single proximity placement 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 B is Wrong: Deploy VM1 and VM2 to different proximity placement groups in the same Azure region.
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 C is Wrong: Connect VM1 and VM2 to a single subnet. 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.
NEW QUESTION # 185
Based on the PaaS prototype, which Azure SQL Database compute tier should you use?

NEW QUESTION # 186
You have SQL Server on an Azure virtual machine that contains a database named Db1.
You need to enable automatic tuning for Db1.
How should you complete the statements? To answer, select the appropriate answer in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: SET AUTOMATIC_TUNING = AUTO
To enable automatic tuning on a single database via T-SQL, connect to the database and execute the following query:
ALTER DATABASE current SET AUTOMATIC_TUNING = AUTO
Setting automatic tuning to AUTO will apply Azure Defaults.
Box 2: SET AUTOMATIC_TUNING (FORCE_LAST_GOOD_PLAN = ON)
To configure individual automatic tuning options via T-SQL, connect to the database and execute the query such as this one:
ALTER DATABASE current SET AUTOMATIC_TUNING (FORCE_LAST_GOOD_PLAN = ON) Setting the individual tuning option to ON will override any setting that database inherited and enable the tuning option. Setting it to OFF will also override any setting that database inherited and disable the tuning option.

NEW QUESTION # 187
You have a burstable Azure virtual machine named VMI that hosts an instance of Microsoft SQL Server.
You need to attach an Azure ultra disk to VMI. The solution must minimize downtime on VMI.
In which order should you perform the actions? To answer, move all actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Explanation:
Explanation:
NEW QUESTION # 188
You have an Azure subscription that contains an Azure SQL database named DB1.
You need to configure Query Store Capture Mode for DB1. The solution must meet the following requirements:
- Ensure that only queries that have significant resource consumption
are tracked.
- Minimize administrative effort.
To what should you set Query Store Capture Mode?
Answer: C
Explanation:
The Query Store Capture Mode should be set to Auto.
Why "Auto" is the Correct Choice
Targeted Tracking: In Auto mode, Query Store captures only "relevant" queries-specifically those with significant resource consumption (CPU, memory, or I/O) or those that execute frequently.
Efficiency: It ignores infrequent or insignificant queries, which prevents the store from being filled with "noise" data.
Minimized Effort: Because the thresholds for what constitutes "significant" resource use are internally determined and managed by Azure, it requires the least administrative overhead.
Incorrect:
[Not A]
None: Stops capturing new queries entirely, which does not meet the requirement to track significant queries.
[Not B]
Custom: Allows for manual threshold setting, but this increases administrative effort.
[Not D]
All: Captures every single query executed, which can lead to high overhead and quickly exhaust storage space.
