Microsoft certification 74-338 74-338 74-338 74-338 examen 74-338
Explanation:
A: Invoke-CsPoolFailover
Invokes the failover process for a Lync Server 2013 pool. Failover refers to the process that occurs
when a pool fails and the current users of that pool are then
signed on to a backup pool. The pool failover process provides a way for administrators to quickly
restore service to users if the Registrar pool they have
logged on to should suddenly become unavailable. If a pool fails, users will automatically be signed
off from Lync Server 2013; if they immediately try to log
back on, they will be redirected to their specified backup pool. C:
* The Move-CsManagementServer cmdlet enables administrators to move the Central Management
Server (and the accompanying Central Management store) from one pool to another. Because there
is always the potential for data loss, not to mention service interruption, any time you move the
Central Management Server, it is recommended that you do not make such a transfer unless:
1.You need to decommission the existing management pool, and must transfer the Central
Management Server before doing so.
2.You've encountered a disaster recovery scenario in which the existing Central Management Server
is no longer accessible.
Before you move the Central Management Server, you must do the following:
*1. Verify that you have created the new Central Management store.
This is done by running the Install-CsDatabase cmdlet and using the CentralManagementDatabase
parameter.
NO.7 You administer a Microsoft Lync Server 2010 Standard Edition server in your network
environment.
You deploy a Microsoft Lync Server 2013 Standard Edition server.
You want to migrate users from Lync Server 2010 to Lync Server 2013. You migrate a test account
from Lync Server 2010 to Lync Server 2013.
You start the Lync 2013 client on one of your test computers and start testing various modalities.
During testing, you decide to test the Meet Now functionality in Lync 2013 client. Meet Now starts a
conference and fails to connect.
You start Clslogging.exe. You generate a log that includes the following information:
You need to identify the cause of the issue. What should you do first?
A. Open another log file from the Lync client in Snooper.
B. Right-click the error message and select Go to nearest entry in trace viewer.
C. Start WireShark and perform the Meet Now test again.
D. Click Show Call Flow Window.

Invoke-CsPoolFailOver: This Front-end pool "poolA.contoso.com" is specified in topology as the next
hop for the Edge server. Failing over this pool may cause External access/Federation/Split-
domain/XMPP features to stop working. Please use Topology Builder to change the Edge internal
next hop setting to point to a different Front-end pool, before you proceed. You need to fail over
PoolA only. What should you do?

Answer: A,C
Microsoft examen certification 74-338 certification 74-338 74-338
Explanation:
Lync Server 2013 uses certificates to provide communications
encryption and server identity authentication. In some cases, such as web publishing through the
reverse proxy, strong subject alternative name (SAN) entry matching to the fully qualified domain
name (FQDN) of the server presenting the service is not required. In these cases, you can use
certificates with wildcard SAN entries (commonly known as "wildcard certificates") to reduce the
cost of a certificate requested from a
public certification authority and to reduce the complexity of the planning process for certificates.
