Overview -

ADatum Corporation is a financial services company that has a main office in New York City.

Existing Environment. Licensing Agreement

ADatum has a Microsoft Volume Licensing agreement that includes Software Assurance.

Existing Environment. Network Infrastructure

ADatum has an on-premises datacenter and an Azure subscription named Sub1.

Sub1 contains a virtual network named Network1 in the East US Azure region.

The datacenter is connected to Network1 by using a Site-to-Site (S2S) VPN.

Existing Environment. Identity Environment

The on-premises network contains an Active Directory Domain Services (AD DS) forest.

The forest contains a single domain named corp.adatum.com.

The corp.adatum.com domain syncs with a Microsoft Entra tenant named adatum.com.

Existing Environment. Database Environment

The datacenter contains the servers shown in the following table.

DB1 and DB2 are used for transactional and analytical workloads by an application named App1.

App1 runs on Microsoft Entra hybrid joined servers that run Windows Server 2022. App1 uses Kerberos authentication.

DB3 stores compliance data used by two applications named App2 and App3.

DB3 performance is monitored by using Extended Events sessions, with the event_file target set to a file share on a local disk of SVR3.

Resource allocation for DB3 is managed by using Resource Governor.

Requirements. Planned Changes -

ADatum plans to implement the following changes:

• Deploy an Azure SQL managed instance named Instance1 to Network1.

• Migrate DB1 and DB2 to Instance1.

• Migrate DB3 to Azure SQL Database.

• Following the migration of DB1 and DB2, hand over database development to remote developers who use Microsoft Entra joined Windows 11 devices.

• Following the migration of DB3, configure the database to be part of an auto-failover group.

Requirements. Availability Requirements

ADatum identifies the following post-migration availability requirements:

• For DB1 and DB2, offload analytical workloads to a read-only database replica in the same Azure region.

• Ensure that if a regional disaster occurs, DB1 and DB2 can be recovered from backups.

• After the migration, App1 must maintain access to DB1 and DB2.

• For DB3, manage potential performance issues caused by resource demand changes by App2 and App3.

• Ensure that DB3 will still be accessible following a planned failover.

• Ensure that DB3 can be restored if the logical server is deleted.

• Minimize downtime during the migration of DB1 and DB2.

Requirements. Security Requirements

ADatum identifies the following security requirements for after the migration:

• Ensure that only designated developers who use Microsoft Entra joined Windows 11 devices can access DB1 and DB2 remotely.

• Ensure that all changes to DB3, including ones within individual transactions, are audited and recorded.

Requirements. Management Requirements

ADatum identifies the following post-migration management requirements:

• Continue using Extended Events to monitor DB3.

• In Azure SQL Database, automate the management of DB3 by using elastic jobs that have database-scoped credentials.

Requirements. Business Requirements

ADatum identifies the following business requirements:

• Minimize costs whenever possible, without affecting other requirements.

• Minimize administrative effort.

You need to recommend a backup solution to restore DB3. The solution must meet the availability requirements.

Which type of backup should you use?

    Correct Answer: C

    To meet the requirement of ensuring that DB3 can be restored if the logical server is deleted, the most appropriate backup type is long-term retention (LTR). LTR is specifically designed to store backups for extended periods, which allows for retention for up to 10 years. These backups are stored in a manner that ensures they can be restored even if the original logical server is deleted. This makes LTR particularly suitable for scenarios where you need to ensure the database can be restored after significant data loss events, including the deletion of the logical server.

Discussion
pjfunnerOption: D

D. point-in-time restore (PITR) - because it supports the restore of a deleted database, which is one of the business requirements. https://azure.microsoft.com/en-us/blog/azure-sql-database-point-in-time-restore/

pjfunner

Actually LTR is the better answer.

Sr18

Indeed LTR will be best "LTR is designed to store backups for extended periods, allowing you to retain full backups for up to 10 years. These backups are stored in a manner that ensures they can be restored even if the original logical server is deleted. This makes LTR particularly suitable for scenarios where you need to ensure that the database can be restored after significant data loss events, including the deletion of the logical server."

Why is LTR better for this scenario? I’m not seeing the actual justification in that opinion anywhere.

scottytohottyOption: C

Correction, LTR because PITR cannot restore if the logical server is deleted. I misread that info somewhere initially, but that completely rules out D, PITR. LTR is the correct answer

scottytohottyOption: D

There is no requirement around long term backups, so I do not see the justification for LTR. PITR is free, can restore deleted databases, and can provide regional outage support, from what I’m researching. https://azure.microsoft.com/en-us/blog/azure-sql-database-point-in-time-restore/ I would love to hear a rebuttle with a citation for LTR over PITR since so many people are arbitrarily saying it is better.

Nelly100Option: D

Given the requirements and the specific need to ensure that DB3 can be restored if the logical server is deleted, the most appropriate backup solution is D. point-in-time restore (PITR). Explanation: Point-in-time restore (PITR): Purpose: Allows you to restore a database to any point in time within the retention period. Use Case: It is particularly useful for recovering from accidental deletions or modifications. Relevance: If the logical server (or the database) is deleted, PITR can help restore the database to the state it was at any specific point within the retention period.

Sr18Option: C

Selected Answer C: long-term retention

scottytohotty

Why? Citation for your reasoning please. LTR has additional costs and PITR fits the requirements that I see.
