You need to ensure that internal Lync 2013 clients can sign in automatically
You support a customer whose network environment includes Microsoft Lync Server 2013
Enterprise, with two Front End Servers and two Back End Servers. The Back End Servers are deployed
in a high availability configuration. You create a Front End pool named pool.contoso.com and
implement DNS load balancing for client access to the Lync servers. Your internal DNS records have
the following configuration:
_gc._tcp.contoso.com SRV priority 0, weight 100, port 3268 dc1.contoso.com_ldap._tcp.contos.com

You need to ensure that internal Lync 2013 clients can sign in automatically. You also need to ensure
that internal traffic is load balanced across the two Front End Servers. What should you do?

You need to ensure that users are able to receive calendar information from Lync Mobile devices
You support a customer who administers Microsoft Lync Server 2013 Enterprise servers in his
company. The pool named lync.contoso.com is configured with the session initiation protocol (SIP)
domain contoso.com. The internal split-DNS domain contoso.com contains the following records:

Users who are running Lync Mobile on their mobile devices report that when they attempt to
retrieve calendar information, they receive an error that references a Microsoft Exchange Web
Services connectivity issue. You need to ensure that users are able to receive calendar information
from Lync Mobile devices. What should you do?
Which two actions should you perform?
You deploy Microsoft Lync Server 2013 Enterprise Edition and create a pool named
Lync2013pool.Contoso.local. You configure the Lync admin URL to be admin.contoso.local. The Front
End and Back End roles are installed on servers named FE2013 and BE2013.
Your DNS server hosts the following records:

Which collection type should you use?
You are developing an application that includes a class named Order. The application will store a
collection of Order objects.
The collection must meet the following requirements:
Use strongly typed members.
Process Order objects in first-in-first-out order.
Store values for each Order object.
Use zero-based indices.
You need to use a collection type that meets the requirements.
Which collection type should you use?
Which code segment should you use?
You are developing an application. The application calls a method that returns an array of integers
named employeeIds. You define an integer variable named employeeIdToRemove and assign a value
to it. You declare an array named filteredEmployeeIds.
You have the following requirements:
Remove duplicate integers from the employeeIds array.
Sort the array in order from the highest value to the lowest value.
Remove the integer value stored in the employeeIdToRemove variable from the employeeIds array.
You need to create a LINQ query to meet the requirements.

Which two actions should you perform?
You are developing an application that includes the following code segment. (Line numbers are
included for reference only.)
The GetAnimals() method must meet the following requirements:
Connect to a Microsoft SQL Server database.
Create Animal objects and populate them with data from the database.
Return a sequence of populated Animal objects.
You need to meet the requirements.

Which code segment should you insert at line 08?
You are developing an application that uses the Microsoft ADO.NET Entity Framework to retrieve
order information from a Microsoft SQL Server database. The application includes the following
code. (Line numbers are included for reference only.)
The application must meet the following requirements:
Return only orders that have an OrderDate value other than null.
Return only orders that were placed in the year specified in the OrderDate property or in a later
year.
You need to ensure that the application meets the requirements.

You are developing a custom collection named LoanCollection for a class named Loan class.
You need to ensure that you can process each Loan object in the LoanCollection collection by using a
foreach loop.
How should you complete the relevant code? (To answer, drag the appropriate code segments to
the correct locations in the answer are
a. Each code segment may be used once, more than once, or not at all. You may need to drag the
split bar between panes or scroll to view content.)
