Microsoft 70-483 Online Exam Practice Questions

QUESTION 1
You have the following code (line numbers are included for reference only): You need to ensure that new instances of
Connection can be created only by other classes by calling the Create method. The solution must allow classes to
inherit from Connection. What should you do?pass4itsure 70-483 exam question q1

A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: B
Explanation: The following list provides the main features of a static class:
*
Contains only static members.
*
Cannot be instantiated.
*
Is sealed.
*
Cannot contain Instance Constructors.
Creating a static class is therefore basically the same as creating a class that contains only static members and a
private constructor. A private constructor prevents the class from being instantiated.
Incorrect:
Not A: An abstract method is a method that is declared without an implementation. Not C: Private methods can be
called from derived classes.
Reference: Static Classes and Static Class Members (C# Programming Guide)

QUESTION 3
HOTSPOT
You are developing the following classes named:
Class1
Class2
Class3
All of the classes will be part of a single assembly named Assembly.dll. Assembly.dll will be used by multiple
applications.
All of the classes will implement the following interface, which is also part ofAssembly.dll:
public interface Interface1
{
void Method1(decimal amount);
void Method2(decimal amount);
}
You need to ensure that the Method2 method for the Class3 class can be executed only when instances of the class are
accessed through the Interface1 interface. The solution must ensure that calls to the Method1 method can be made
either through the interface or through an instance of the class.
Which signature should you use for each method? (To answer, select the appropriate signature for each method in the

You need to complete the WriteTextAsync method. The solution must ensure that the code is not blocked while the file
is being written. Which code should you insert at line 12?

pass4itsure 70-483 exam question q4-1

A. Option A
B. Option B
C. Option C
D. Option D
Correct Answer: D
Explanation: await sourceStream.WriteAsync(encodedText, 0, encodedText.Length);
The following example has the statement await sourceStream.WriteAsync(encodedText, 0, encodedText.Length);,
which is a contraction of the following two statements:
Task theTask = sourceStream.WriteAsync(encodedText, 0, encodedText.Length); await theTask;
Example: The following example writes text to a file. At each await statement, the method immediately exits. When the
file I/O is complete, the method resumes at the statement that follows the await statement. Note that the async modifier
is
in the definition of methods that use the await statement.
public async void ProcessWrite()
{
string filePath = @”temp2.txt”;
string text = “Hello World\r\n”;
await WriteTextAsync(filePath, text);
}
private async Task WriteTextAsync(string filePath, string text) {
byte[] encodedText = Encoding.Unicode.GetBytes(text);
using (FileStream sourceStream = new FileStream(filePath, FileMode.Append, FileAccess.Write, FileShare.None,
bufferSize: 4096, useAsync: true))
{
await sourceStream.WriteAsync(encodedText, 0, encodedText.Length); };

A. VDC
B. VEM
C. vPC
D. VSM
E. VRRP
Correct Answer: BD
The Cisco Nexus 1000V Series consists of two main types of components that can virtually emulate a 66-slot modular
Ethernet switch with redundant supervisor functions:
Virtual Ethernet module (VEM)-data plane: This lightweight software component runs inside the hypervisor. It enables
advanced networking and security features, performs switching between directly attached virtual machines, provides
uplink capabilities to the rest of the network, and effectively replaces the vSwitch. Each hypervisor is embedded with
one VEM.
Virtual supervisor module (VSM)-control plane: This standalone, external, physical or virtual appliance is responsible for
the configuration, management, monitoring, and diagnostics of the overall Cisco Nexus 1000V Series system (that is,
the combination of the VSM itself and all the VEMs it controls) as well as the integration with VMware vCenter. A single
VSM can manage up to 64 VEMs. VSMs can be deployed in an active-standby model, helping ensure high availability.

B. IEEE 802.1Qbb
C. IEEE 802.1Qaz
D. IEEE 802.1p
E. IEEE 802.1x

QUESTION 13
You configure STP on a switch that is attached to a Cisco FabricPath domain and that has the vPC feature deployed.
How do you configure STP on the switch in the Cisco FabricPath domain on VLAN 10?
A. switch(config)# spanning-tree vlan 10 priority 0 switch(config)# spanning-tree pseudo-information switch(config-
pseudo)# vlan 10 root priority 0
B. switch(config)# spanning-tree vlan 10 priority 8192 switch(config)# spanning-tree pseudo-information switch(config-
pseudo)# vlan 10 root priority 4096
C. switch(config)# spanning-tree vlan 10 priority 4096 switch(config)# spanning-tree pseudo-information switch(config-
pseudo)# vlan 10 root priority 8192
D. switch(config)# spanning-tree vlan 10 priority 0 switch(config)# spanning-tree pseudo-information switch(config-
pseudo)# vlan 10 root priority 4096
Correct Answer: B
Note that it is fine to use the spanning-tree priority command and the spanning-tree pseudo-information command
together, but the root priority in the pseudo-information needs to be a lower value (higher priority) than the spanning-tree
priority to make sure that the remaining working Cisco FabricPath switch is sending a superior BPDU with the common
FabricPath bridge ID and the configured spanning-tree pseudo-information priority and remains at the spanning-tree
root. Reference: https://www.cisco.com/c/dam/en/us/products/collateral/switches/nexus-7000-series-switches/white_paper_c07-728188.pdf page 44

Database mirroring is a solution for increasing the availability of a SQL Server database.
Mirroring is implemented on a per-database basis and works only with databases that use the full recovery model.

 

QUESTION 5
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.
Your company is developing a new business intelligence application that will access data in a Microsoft Azure SQL
Database instance. All objects in the instance have the same owner.
A new security principal named BI_User requires permission to run stored procedures in the database. The stored
procedures read from and write to tables in the database. None of the stored procedures perform IDENTIFY_INSERT
operations or dynamic SQL commands.
The scope of permissions and authentication of BI_User should be limited to the database. When granting permissions,
you should use the principle of least privilege.
You need to create the required security principals and grant the appropriate permissions.
Solution: You run the following Transact-SQL statement in the database:pass4itsure 70-764 exam question q5

Does the solution meet the goal?
A. Yes
B. No
Correct Answer: B
We need to add a login.
Secondly, it is enough to grant EXECUTE permissions on the stored procedures for database roles you want to be able
to access the data. We do not need to add roles to this user.
Note: One method of creating multiple lines of defense around your database is to implement all data access using
stored procedures or user-defined functions. You revoke or deny all permissions to underlying objects, such as tables,
and
grant EXECUTE permissions on stored procedures. This effectively creates a security perimeter around your data and
database objects.
Best Practices
Simply writing stored procedures isn\\’t enough to adequately secure your application. You should also consider the
following potential security holes.
Grant EXECUTE permissions on the stored procedures for database roles you want to be able to access the data.
Revoke or deny all permissions to the underlying tables for all roles and users in the database, including the public role.
All users inherit permissions from the public. Therefore denying permissions to public means that only owners and
sysadmin
members have access; all other users will be unable to inherit permissions from membership in other roles.
Do not add users or roles to the sysadmin or db_owner roles. System administrators and database owners can access
all database objects.

QUESTION 6
DRAG DROP
You have a table that contains a column named Department. Each user is assigned to a database role name that
matches the Department column value. Users authenticate to the database with accounts that are assigned to their department’s database role. You belong to the db_owner role and have the rights to run the EXECUTE AS USER
statement.
Users must only view records that match their department.
You need to implement Microsoft SQL Server row-level security (RLS) and test the implementation.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions
to the answer area and arrange them in the correct order.

QUESTION 7
You administer a Microsoft SQL Server 2016 server.
You plan to deploy new features to an application.
You need to evaluate existing and potential clustered and non-clustered indexes that will improve performance.
What should you do?
A. Query the sys.dm_db_index_usage_stats DMV.
B. Query the sys.dm_db_missing_index_details DMV.
C. Use the Database Engine Tuning Advisor.
D. Query the sys.dm_db_missing_index_columns DMV.
Correct Answer: C
The Microsoft Database Engine Tuning Advisor (DTA) analyzes databases and makes recommendations that you can
use to optimize query performance. You can use the Database Engine Tuning Advisor to select and create an optimal
set of indexes, indexed views, or table partitions without having an expert understanding of the database structure or the internals of SQL Server. Using the DTA, you can perform the following tasks. Troubleshoot the performance of a
specific problem query Tune a large set of queries across one or more databases Perform an exploratory what-if
analysis of potential physical design changes Manage storage space References: https://docs.microsoft.com/en-us/sql/relational-databases/performance/database-engine-tuning-advisor

 

QUESTION 8
You administer a single server that contains a Microsoft SQL Server 2016 default instance.
You plan to install a new application that requires the deployment of a database on the server. The application login
requires sysadmin permissions.
You need to ensure that the application login is unable to access other production databases.
What should you do?
A. Use the SQL Server default instance and configure an affinity mask.
B. Install a new named SQL Server instance on the server.
C. Use the SQL Server default instance and enable Contained Databases.
D. Install a new default SQL Server instance on the server.
Correct Answer: B

SQL Server supports multiple instances of SQL Server on a single server or processor, but only one instance can be the
default instance. All others must be named instances. A computer can run multiple instances of SQL Server
concurrently, and each instance runs independently of other instances.

All users must be able to benefit from the index.
2.
FirstName must be added to the index as an included column.
What should you do?
A. Create a clustered index on the table.
B. Create a nonclustered index on the table.
C. Create a nonclustered filtered index on the table.
D. Create a clustered column store index on the table.
E. Create a nonclustered column store index on the table.
F. Create a hash index on the table.
Correct Answer: B
By including nonkey columns, you can create nonclustered indexes that cover more queries. This is because the
no key columns have the following benefits:
They can be data types not allowed as index key columns.
They are not considered by the Database Engine when calculating the number of index key columns or index key size.

Returning Data by Using OUTPUT Parameters
If you specify the OUTPUT keyword for a parameter in the procedure definition, the stored procedure can return the current value of the parameter to the calling program when the stored procedure exits.
SQL Server stored procedures, views and functions are able to use the WITH ENCRYPTION option to disguise the
contents of a particular procedure or function from discovery.
Native Compilation of Tables and Stored Procedures
In-Memory OLTP introduces the concept of native compilation. SQL Server can natively compile stored procedures that
access memory-optimized tables. SQL Server is also able to natively compile memory-optimized tables. Native
compilation
allows faster data access and more efficient query execution than interpreted (traditional) Transact-SQL. Native
compilation of tables and stored procedures produce DLLs.
