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

1. 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. Extension ranges by location are:

Numbers in the Seattle HQ have been normalized to the format:
+1425555XXXX; ext = XXXX
XXXX represents the last 4 digits of the users' extension. Which Trunk
Configuration Translation Rule allows calls to the legacy PBX in the Seattle HQ?

A) Matching: ^\+14255550\d{4}; ext=([0, l, 2]\d{3})$ Translation: $1
B) Matching: ^\+1425555([0, l, 2]\d{3}); ext=[0, 1, 2]\d{3} Translation: 8$1
C) Matching: ^\+1425555[0,l,2]\d{3};ext = [0, l, 2](\d{3})$ Translation: 8$1
D) Matching: ^\+1425555([0, l, 2]\d{3}); ext=[0, l, 2]\d{3} Translation: $1

2. Refer to the exhibits.

An organization implements Call Admission Control for Lync to control bandwidth usage and assure a high quality experience. Users in the Portland office frequently use Lync Enterprise telephony and conferencing features offered from the Lync infrastructure in the Chicago site. An administrator is determining which type of audio and video codecs will optimize bandwidth utilization on a per- session basis. The administrator needs to prevent media that is traversing the network connection between Portland and Chicago from using the G.711 codec without impacting the ability to use the RTAudio wideband codec. Which action meets these requirements?

A) Change the Audio Session Limit in the bandwidth policy for the Portland site to 106 kbps.
B) Change the Audio Session Limit in the bandwidth policy for the Portland site to 100 kbps
C) Change the Audio Session Limit in the bandwidth policy for the Portland site to 50 kbps.
D) Change the Audio Session Limit in the bandwidth policy for the Portland site to 105 kbps.

3. Contoso wants to interoperate its existing legacy video conferencing solution with a newly deployed Lync infrastructure using a qualified, third-party gateway.
Which two steps must an administrator take, at a minimum, to configure the qualified gateway with Lync? (Choose two.)

A) Configure the gateway as trusted server with Lync.
B) Register the gateway in Lync.
C) Configure a static route to the gateway in Lync.
D) Configure SIP over TCP in Lync.
E) Add gateway as a contact object in Active Directory.

4. Refer to the exhibit.

An organization is using Lync Enterprise Voice to make and receive external PSTN calls to and from the Lync client. The exhibit displays a typical call flow experienced for outgoing PSTN" calls for the organization The Lync infrastructure is connected to a PBX that is qualified with Lync Server 2010, but does not support Media Bypass. Which two CODECs can be used on the Lync client given the media path displayed in the exhibit? (Choose two.)

A) Siren
B) G.729
C) RTAudio Narrow Band
D) G.711
E) RTAudio Wide Band

5. 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
