B. VIEW SERVER STATE
C. VIEW DEFINITION
D. CONTROL SERVER

NO.2 DRAG DROP
You plan to deploy SQL Server 2014.
Your company identifies the following monitoring requirements for the database:
- An e-mail message must be sent if the SQL Server Authentication mode changes.
- An e-mail message must be sent if CPU utilization exceeds 90 percent.
You need to identify which feature meets each monitoring requirement.
Which features should you identify?
To answer, drag the appropriate feature to the correct monitoring requirement in the answer area.
Answer:

NO.3 You need to recommend a disaster recovery solution for the Dev database.
What should you include in the recommendation?
A. The full recovery model, full backups, and transaction log backups
B. The full recovery model, full backups, and differential backups
C. The bulk-logged recovery model and full backups
D. The simple recovery model and full backups
Answer: D

70-465認定デベロッパー
Explanation:
*Scenario: You must be able to recover data from the Dev database if data is lost accidentally. You
have a Recovery Point Objective (RPO) of one day.
*The simple recovery model provides the simplest form of backup and restore. This recovery model
supports both database backups and file backups, but does not support log backups. Transaction log
data is backed up only with the associated user data. The absence of log backups simplifies managing
backup and restore. However, a database can be restored only to the end of the most recent backup.
Incorrect:
Not B: The bulk-logged recovery model is a special-purpose recovery model that should be used only
intermittently to improve the performance of certain large-scale bulk operations, such as bulk
imports of large amounts of data.

NO.4 You need to implement changes to the system to reduce contention and improve
performance of the SalesOrderDetail table.
Which three actions should you perform? Each correct answer presents part of the solution. Choose
three.
A. Use (SNAPSHOT] hints in the report queries
B. SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
C. Use (SNAPSHOT] hints in the update statements
D. ALTER DATABASE [ProdDB] SET READ_COMMITTED_SNAPSHOT OFF
E. SET TRANSACTION ISOLATION LEVEL SNAPSHOT
F. Use (TABLOCK) hints in the report queries
G. ALTER DATABASE [ProdDB] SET READ_COMMITTED_SNAPSHOT ON
H. ALTER DATABASE [ProdDB] SET ALLOW_SNAPSHOT_ISOLATION ON
Answer: A,B,G
Explanation:
*Scenario:
The SalesOrderDetail table holds the details about each sale. It is in the Sales schema
owned by the SalesStaff Windows group.
This table is constantly being updated, inserted into, and read.
*Regardless of which office runs a sales force report, the SalesOrderDetail table should only return
valid, committed order data; any orders not yet committed should be ignored.
*READ_COMMITTED_SNAPSHOT { ON | OFF } ON Enables Read-Committed Snapshot option at the
database level. When it is enabled, DML statements start generating row versions even when no
transaction uses Snapshot Isolation. Once this option is enabled, the transactions specifying the read
committed isolation level use row versioning instead of locking. When a transaction runs at the read
committed isolation level, all statements see a snapshot of data as it exists at the start of the
statement. OFF Turns off Read-Committed Snapshot option at the database level. Transactions
specifying the READ COMMITTED isolation level use locking. ALTER DATABASE SET Options (Transact-
SQL) SET Statements (Transact-SQL)
