Your network has Lync Server 2010 deployed. The network administrator plans to use a protocol analyzer to identify network trends. You need to identify the protocol required to monitor Microsoft Lync 2010 voice traffic. Which protocol should you identify?
A.
IPSec
B.
NTP
C.
CIPE
D.
SRTP
Explanation:
By reducing the port range greatly, you reduce server capacity. An administrator who is knowledgeable about media port requirements and scenarios should do this only for specific reasons. For this reason, altering the default port range is not recommended.
Organizations that employ Internet Protocol security (IPSec) for packet security are advised to disable it for media ports because the security handshake required by IPSec delays call setup. IPSec is unnecessary for media ports because Secure Real-Time Transport Protocol (SRTP) encryption secures all media traffic between the Mediation Server and the internal Communications Server network.
