1. Which recovery model requires transaction log backups to prevent
the transaction log from growing indefinitely?
A. Simple
B. Full
C. Bulk-logged
D. Model
B. Full
Rationale: In the full recovery model, the transaction log
continues to grow until a transaction log backup is performed.
The simple recovery model automatically truncates the log, and
bulk-logged still requires log backups but minimally logs bulk
operations.
2. A database is in the simple recovery model. Which type of
recovery is NOT possible?
A. Full database restore
B. Differential restore
C. Point-in-time restore
D. File restore
C. Point-in-time restore
Rationale: Point-in-time recovery requires transaction log
backups, which are not available in the simple recovery model
because the log is automatically truncated.
3. What is the purpose of a differential backup in SQL Server?
A. To back up all data in the database
1
, B. To back up only the data that has changed since the last full
backup
C. To back up only the transaction log
D. To back up only the schema
B. To back up only the data that has changed since the last full
backup
Rationale: A differential backup captures all extents that have
changed since the last full backup, making it smaller and faster
than a full backup while simplifying recovery compared to
transaction log backups.
4. Which statement about SQL Server authentication modes is
correct?
A. Windows Authentication mode allows only Windows accounts
to connect
B. Mixed Mode allows both Windows and SQL Server logins
C. SQL Server Authentication mode is the most secure option
D. Mixed Mode should always be enabled for maximum
compatibility
B. Mixed Mode allows both Windows and SQL Server logins
Rationale: Mixed Mode authentication permits both Windows
authenticated logins and SQL Server authenticated logins.
Windows Authentication is generally considered more secure.
5. Which fixed server role in SQL Server has unrestricted access to
all server-level permissions and can perform any activity?
A. serveradmin
B. securityadmin
C. sysadmin
D. dbcreator
C. sysadmin
2
, Rationale: The sysadmin fixed server role can perform any
activity in SQL Server, making it the most powerful server-level
role.
6. Which fixed database role can manage all permissions, object
ownerships, roles, and role memberships within a database?
A. db_owner
B. db_securityadmin
C. db_accessadmin
D. db_datareader
B. db_securityadmin
Rationale: The db_securityadmin fixed database role can
manage all permissions, object ownerships, roles, and role
memberships within its database.
7. What is the purpose of a SQL Server login?
A. To authenticate a principal at the server level
B. To authorize access to database objects
C. To define a database role
D. To configure backup schedules
A. To authenticate a principal at the server level
Rationale: A login is a server-level principal used for
authentication. Authorization to database objects is granted
through database users and roles.
8. What is the difference between a SQL Server login and a database
user?
A. A login authenticates at the server level; a user is mapped to a
login and authorized within a database
B. A login authorizes within a database; a user authenticates at the
server level
C. They are identical
3
, D. A user can exist without a login
A. A login authenticates at the server level; a user is mapped to
a login and authorized within a database
Rationale: Logins authenticate at the server level, while database
users are mapped to logins and hold permissions within a
specific database.
9. Which Always On feature provides high availability by
maintaining a set of readable secondary replicas that can
automatically fail over?
A. Failover Cluster Instance (FCI)
B. Always On Availability Groups
C. Database Mirroring
D. Log Shipping
B. Always On Availability Groups
Rationale: Always On Availability Groups support a set of
primary and secondary replicas with automatic or manual
failover, and secondary replicas can be configured for read-only
access.
10. What underlying Windows feature is required for Always On
Availability Groups?
A. Active Directory Domain Services
B. Windows Server Failover Clustering (WSFC)
C. Internet Information Services (IIS)
D. Hyper-V
B. Windows Server Failover Clustering (WSFC)
Rationale: Always On Availability Groups require Windows
Server Failover Clustering for health detection and automatic
failover, though the availability group itself is configured within
SQL Server.
