NEW QUESTION # 170
You have an Azure Databricks resource.
You need to log actions that relate to changes in compute for the Databricks resource.
Which Databricks services should you log?
- A. DBFS
- B. jobs
- C. SSH
- D. clusters
- E. workspace
Answer: E
Explanation:
Cloud Provider Infrastructure Logs.
Databricks logging allows security and admin teams to demonstrate conformance to data governance
standards within or from a Databricks workspace. Customers, especially in the regulated industries, also need records on activities like:
User access control to cloud data storage
Cloud Identity and Access Management roles
User access to cloud network and compute
Azure Databricks offers three distinct workloads on several VM Instances tailored for your data analytics workflow-the Jobs Compute and Jobs Light Compute workloads make it easy for data engineers to build and execute jobs, and the All-Purpose Compute workload makes it easy for data scientists to explore, visualize, manipulate, and share data and insights interactively.

NEW QUESTION # 174
You create a new Azure SQL managed instance named SQL1 and enable Database Mail extended stored You need to ensure that SQ Server Agent jobs running on SQL 1 can notify when a failure Occurs Which three actions should you perform in sequence 7 TO answer. move the appropriate actions from the list Of actions to answer area and arrange them in correct order.
Answer:
Explanation:
1 - Create Database Mail account.
2 - Create a pfofile named AzureManagedInstance_dbmail_pfofile.
3 - Enable email notifications upon failure.
NEW QUESTION # 175
You have an Azure SQL database named DB1.
You need to ensure that DB1 will support automatic failover without data loss if a datacenter fails. The solution must minimize costs.
Which deployment option and pricing tier should you configure?
- A. Azure SQL Database managed instance Business Critical
- B. Azure SQL Database Standard
- C. Azure SQL Database serverless
- D. Azure SQL Database Premium
- E. This feature is not available in SQL Managed Instance.
Answer: D
Explanation:
By default, the cluster of nodes for the premium availability model is created in the same datacenter. With the introduction of Azure Availability Zones, SQL Database can place different replicas of the Business Critical database to different availability zones in the same region. To eliminate a single point of failure, the control ring is also duplicated across multiple zones as three gateway rings (GW). The routing to a specific gateway ring is controlled by Azure Traffic Manager (ATM). Because the zone redundant configuration in the Premium or Business Critical service tiers does not create additional database redundancy, you can enable it at no extra cost. By selecting a zone redundant configuration, you can make your Premium or Business Critical databases resilient to a much larger set of failures, including catastrophic datacenter outages, without any changes to the application logic. You can also convert any existing Premium or Business Critical databases or pools to the zone redundant configuration.

NEW QUESTION # 179
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have an Azure SQL database named Sales.
You need to implement disaster recovery for Sales to meet the following requirements:
* During normal operations, provide at least two readable copies of Sales.
* Ensure that Sales remains available if a datacenter fails.
Solution: You deploy an Azure SQL database that uses the General Purpose service tier and geo-replication.
Does this meet the goal?
- A. Yes
- B. No
Answer: B
Explanation:
Instead deploy an Azure SQL database that uses the Business Critical service tier and Availability Zones.
Note: Premium and Business Critical service tiers leverage the Premium availability model, which integrates compute resources (sqlservr.exe process) and storage (locally attached SSD) on a single node. High availability is achieved by replicating both compute and storage to additional nodes creating a three to four- node cluster.
By default, the cluster of nodes for the premium availability model is created in the same datacenter. With the introduction of Azure Availability Zones, SQL Database can place different replicas of the Business Critical database to different availability zones in the same region. To eliminate a single point of failure, the control ring is also duplicated across multiple zones as three gateway rings (GW).

NEW QUESTION # 182
You have an Azure SQL database that contains a table named factSales. FactSales contains the columns shown in the following table.
FactSales has 6 billion rows and is loaded nightly by using a batch process.
Which type of compression provides the greatest space reduction for the database?
- A. page compression
- B. row compression
- C. columnstore archival compression
- D. columnstore compression
Answer: C
Explanation:
Explanation
Columnstore tables and indexes are always stored with columnstore compression. You can further reduce the size of columnstore data by configuring an additional compression called archival compression.
Note: Columnstore - The columnstore index is also logically organized as a table with rows and columns, but the data is physically stored in a column-wise data format.

NEW QUESTION # 183
You are planning disaster recovery for the failover group of an Azure SQL Database managed instance.
Your company's SLA requires that the database in the failover group become available as quickly as possible if a major outage occurs.
You set the Read/Write failover policy to Automatic.
What are two results of the configuration? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
- A. In the event of an outage, the minimum delay for the databases to fail over in the primary instance will be one hour.
- B. In the event of an outage, you can selectively fail over individual databases.
- C. In the event of an outage, the databases in the primary instance will fail over immediately.
- D. In the event of a datacenter or Azure regional outage, the databases will fail over automatically.
- E. In the event of an outage, you can set a different grace period to fail over each database.
Answer: A,D
Explanation:
A: Auto-failover groups allow you to manage replication and failover of a group of databases on a server or all databases in a managed instance to another region.
E: Because verification of the scale of the outage and how quickly it can be mitigated involves human actions by the operations team, the grace period cannot be set below one hour. This limitation applies to all databases in the failover group regardless of their data synchronization state.
Incorrect Answers:
C: individual SQL Managed Instance databases cannot be added to or removed from a failover group.

NEW QUESTION # 184
You need to recommend an availability strategy for an Azure SQL database. The strategy must meet the
following requirements:
Support failovers that do not require client applications to change their connection strings.
Replicate the database to a secondary Azure region.
Support failover to the secondary region.
What should you include in the recommendation?
- A. failover groups
- B. Availability Zones
- C. geo-replication
- D. transactional replication
Answer: C
Explanation:
Active geo-replication is an Azure SQL Database feature that allows you to create readable secondary databases of individual databases on a server in the same or different data center (region).
Incorrect Answers:
C: Availability Zones are unique physical locations within a region. Each zone is made up of one or more
datacenters equipped with independent power, cooling, and networking.
