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

1. An organization is deploying Microsoft Lync Server 2010 and needs to identify the numbering plan that will require the smallest amount of change to the legacy PBX environment. The legacy PBX:
Supports 4 digit extension dialing with extensions in the following ranges 4000-5999.
Has been configured to send calls in the range of 6000-7999 to be routed to the Lync Mediation server.
Normalization rules have been added to Lync to convert all inbound calls to E.
164 format
Which approach will allow 4 digit dialing between Lync and the legacy PBX?

A) Assign Lync users a LineURI in the range of+14255556000 to
+14255557999. Create a Trunk
Configuration translation rule to send only the last 4 digits to the legacy PBX.
B) Assign Lync users a LineURI in the range of+6000 to +7999. Create a Trunk
Configuration translation rule to send only the last 4 digits to the legacy PBX.
C) Assign Lync users a LineURI in the range of+14255556000 to +14255557999.
Configure the digit manipulation on the Legacy PBX to strip all but the last 4
digits on inbound calls from the Lync server.
D) Assign Lync users a LineURI in the range of+6000 to +7999. Configure the
digit manipulation on the Legacy PBX to strip all but the last 4 digits on inbound
calls from the Lync server.

2. 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 London_Route to include numbers starting with +1. Configure the numbers starting with +1 with a lower priority than the numbers starting with +44.
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) 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.
D) Change Redmond_Route to include the London Gateway. Configure the London gateway with a lower priority than the Redmond gateway.

3. A customer deployed Microsoft Lync Server 2010 and is trying to interoperate with a legacy PBX infrastructure of 2 PBXs in different locations. The company uses five-digit, internal extensions. The first digit indicates user location and PBX. Changes to the legacy PBX dial plan should be minimized. Lync users will retain existing extension once moved to Lync Enterprise Voice. Users should maintain existing dialing behaviors.

Which Normalization rule allows calls to the legacy PBX in Seattle Retail?

A) Matching: ^8(\d{4})$ Translation: +14255550099; ext=$1
B) Matching: ^(8\d{4))$ Translation: +1425555$1; ext=$1
C) Matching: ^8(00\d{2})$ Translation: +1425555$ 1; ext=$1
D) Matching: ^8(00\d{2})$ Translation: +14255550099; ext=$1

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