Microsoft Lync Server 2010-Advanced Design and Deployment Sample Questions:

1. How should an administrator configure a hardware load balancer for a front end pool if DNS load balancing is in use?

A) Load balance ports TCP 80 (http), TCP 443 (https) and TCP 135 (DCOM)
B) Load balance ports TCP 443 (https), TCP 135 (DCOM), and TCP 5061 (SIP TLS)
C) Load balance ports TCP 80 (http) and TCP 443 (https)
D) Load balance port TCP 443 (https) and TCP 5061 (SIP TLS)

2. An organization runs Microsoft Lync Server 2010 and all users are enabled for Enterprise Voice. Exchange Server 2010 Unified Messaging (UM) is deployed to provide voice mail functionality to the end user. All users in the organization use the Lync 2010 client and Outlook 2010. A user calls voicemail from the Lync Client and the attempt is unsuccessful. The Exchange server log contains the error message: "The Unified Messaging server failed to exchange the required certificates with an EP gateway to enable Transport Layer Security (TLS) for an incoming call." Which action solves this problem?

A) Replace the Exchange Server Certificate.
B) Re-run the Exchange UM Integration utility OcsUmUtil.exe on the Lync Front End server.
C) Import the trusted certificate root chain to the Lync Client
D) Replace the certificate of the IP gateway.

3. Refer to the exhibit.

Contoso has Lync infrastructure deployed across all of its locations. After looking at the network reports, an administrator discovers that the link between central site and branch site has an average of 5% packet loss. CAC is not configured on the link. What is the maximum bandwidth in kbps consumed when a Lync client from central site makes a voice call to a Lync client in the branch site?

A) 67
B) 166
C) 49.8
D) 96

4. A customer has four digit internal extensions that should be translated as displayed in the table.

Which normalization rule will provide the desired expression?

A) Pattern to match: ^7(\d{4})$ Translation pattern: +1425555$ 1
B) Pattern to match: ^7(\d{3})$ Translation pattern: +14255557$1
C) Pattern to match: ^7(\d[3])$ Translation pattern: +14255557$1
D) Pattern to match: ^7(\d[4])$ Translation pattern: +1425555$ 1

5. Contoso has PSTN gateways in London and Redmond. All calls to the US starting with +1 are routed to the Redmond gateway. All calls to London starting +44 are routed to London. If the gateway in Redmond is unavailable, calls to +1 numbers should be routed via the London gateway. Contoso has the following configuration:
One global voice policy, called Global_VoicePolicyf which includes a single PSTN Usage called Global_Usage.
Global_Usage has two associated routes: Redmond_Route and London_Route.
Redmond_Route routes all calls starting with +1 to the Redmond gateway.
London_Route routes all calls starting with +44 to the London gateway.
An administrator needs to ensure that calls beginning with +1 are routed out the
London gateway only if the Redmond gateway is unavailable. Which set of
changes should the administrator make to the voice configuration?

A) Change Redmond_Route to include the London Gateway. Configure the London gateway with a lower priority than the Redmond gateway.
B) Create a new route called US_Fallback that will route calls starting with +1 to the London gateway. Add the route US_Fallback to the PSTN Usage Global_Usage. Configure the route US_Fallback with a lower priority than the Redmond_Route.
C) Change London_Route to include numbers starting with +1. Configure the numbers starting with +1 with a lower priority than the numbers starting with +44.
D) Create a new route called US_Fallback that will route calls starting with +1 to the London gateway. Create a new PSTN Usage called Fallback_Usage and add it to the voice policy Global_VoicePolicy. Configure the PSTN Usage Fallback_Usage to have a lower priority than Global_Usage.
