Microsoft Lync 2013 Depth Support Engineer 074-338 Prüfungsfragen mit Lösungen:

1. Your customer's company has a main office and five branch offices located in different cities. Your customer has a Microsoft Lync Server 2013 datacenter configured with Enterprise Voice at the main office. The customer has deployed a Survivable Branch Appliance (SBA) at the first branch office and connected it to a public switched telephone network (PSTN) by using a Tl trunk line provided by your service provider. The gateway is configured to use fully qualified domain names (FQDNs). All functionality has been tested by using pilot users at the branch office. The customer reports that they tested branch isolation by disconnecting the wide area network (WAN) from their branch office and making an outbound call. The call was successful. Next, they made an inbound call to the branch office and the call failed. To troubleshoot the issue, you begin a trace of IncomingAndOutgoingCalls by using centralized logging, and make an inbound call. You open the log in snooper and search for incoming calls with the phone number from which you are calling. You do not find any messages. You open the syslog from the gateway side of the SBA and discover that messages are sent to the Lync Mediation server pool, but no responses have been received. You connect the WAN from the branch office and make an inbound call. The call is successful. Your investigation suggests that there is a configuration error on the Gateway side of the SBA. You need to identify the configuration error that causes inbound calls to fail. What should you check?

A) DNS settings on the gateway
B) The domain controller at the branch office
C) Dynamic Host Configuration Protocol (DHCP) options on the branch DHCP server
D) Route settings of the gateway

2. You support a datacenter that runs Microsoft Lync Server 2013 with Enterprise Voice (EV). The company has opened two new satellite branches and configured one with a Survivable Branch Appliance (SBA) and the other with a Survivable Branch Server (SBS). Neither branch has a DNS server. A wide area network (WAN) outage occurs and EV stopped working for the branch users. You need to ensure that EV functionality continues in the event of WAN outages. What are two possible ways to achieve this goal? (Each correct answer presents a complete solution. Choose two.)

A) Enable backup Registrar discovery by configuring Dynamic Host Configuration Protocol (DHCP) option 60 on the branch site's DHCP server.
B) Enable backup Registrar discovery by configuring the SBA or SBS to respond to Dynamic Host Configuration Protocol (DHCP) 120 queries.
C) Enable backup Registrar discovery by configuring Dynamic Host Configuration Protocol (DHCP) option 55 on the branch site's DHCP server.
D) Enable backup Registrar discovery by configuring Dynamic Host Configuration Protocol (DHCP) option 120 on the branch site's DHCP server to point to the fully qualified domain name (FQDN) of the SBA or SBS.

3. You support a Microsoft Lync Server 2013 Enterprise pool deployed in a high availability configuration for Back End Servers named Backend 1 and Backend2. You execute the Get-CSDatabaseMirrorState cmdlet and discover the following errors.

You need to resolve the connectivity issue and bring up the mirror databases to the synchronized state between the Back End Servers. What should you do?

A) From the Front End Server, create the inbound rule on the firewall.
B) Run the Test-CsDatabase cmdlet.
C) From the mirror Back End Server, create the inbound rule on the firewall.
D) Run the Invoke-CsPoolFailOver cmdlet.

4. You support a Microsoft Lync Server 2013 Enterprise pool deployed in a high availability configuration for Back End Servers. You execute the Get-CSDatabaseMirrorState cmdlet. You discover the disconnected state of SQL mirror databases as well as network connection errors pointed to the inaccessible SQL mirror server. You need to bring up the mirror databases to the synchronized state between the Back End Servers. What should you do?

A) From the mirror Back End Server, modify the inbound rule on the firewall.
B) Reissue the internal Lync certificate to include the fully qualified domain name (FQDN) of the mirror Back End Server.
C) From the Lync 2013 Management Shell, run the Enable-CSComputer cmdlet.
D) From the Front End Server, modify the inbound rule on the firewall.

5. You support a customer whose network environment includes Microsoft Lync Server 2013 Enterprise Voice deployed at two sites named Sitel and 5ite2. All users require extension dialing. Only direct inward dialing will be used for auto attendants or response groups. The extension numbers in four-digit format are
stored in the telephoneNumber attribute on the users' Active Directory Domain Services (AD DS) account. Sitel uses 2xxx extensions, and Site2 uses 3xxx extensions. You want to retain the four-digit extensions in Active Directory, but also present the numbers as valid numbers in the Lync 2013 client. You need to ensure that four-digit dialing normalizes properly in the address book for Lync. What should you do?

A) Use absconfig.exe from the Lync Resource Kit and change the flag of telephoneNumber to be included in the address book generation.
B) Modify the Company_Phone_Number_Normalization_Rules.txt file and add the following rules: ^(2\d{3})$ -- +15197778888;ext=$1^(3\d{3})$ -- +14163334444;ext=$1
C) In the Lync Control Panel, under voice routing and dial plan, modify the global dial plan to add the following rules: ^(2\d{3})$ --+15197778888;ext=$1^(3\d{3})$ -- +14163334444;ext=$1
D) Modify the Company_Phone_Number_Normalization_Rules.txt file and add the following rules: ^(2d\{3})$ -- +15197778888;ext=$1^(3d\{3})$ -- +14163334444;ext=$1
