Module 5 Flashcards
These are your organization’s own users, such as business travelers and telecommuters, when they are working outside your firewalls and are using their laptops with Lync 2010 client software or other Lync Server 2010 supported devices. Remote users have virtually all the same capabilities when working remotely that they have when working inside the company firewall
Remote users
Users from a trusted ___ organization can be authorized for remote access with one of two service options chosen during deployment
Federated users
IM and presence only
IM and presence, web conferencing, and audio/video (A/V) conferencing
You can provide federated users with access to features of Lync Server 2010, except for the
address book
have no user account in your organization or federated organizations. By invitation, such users may participate in IM, web conferences, and audio conferences hosted on your internal deployment.
Anonymous users
___ users can be authorized for one of two service options chosen during deployment
Public IM users
IM and presence only
IM and presence, web conferencing, and A/V conferencing (peer-to-peer IM conferencing,
viewing presence, participation in A/V conferencing by using the latest Windows Live Messenger
client, which is currently in Beta IIRC
_________ service provides a single, trusted connection point for both outbound and inbound Session Initiation Protocol (SIP) traffic
Access Edge service
__________enables external users to join meetings that are hosted on your internal LyncServer 2010 communications software deployment.
Web Conferencing Edge service
service makes audio, video, application sharing, and file transfer available to external users. Yourusers can add audio and video to meetings that include external participants, and they can share audio and video directly with an external user in point-to-point sessions. It also provides support for desktop sharing and file transfer.
A/V Edge service
The three Edge topologies
Single Consolidated Edge topology
Scaled consolidated Edge topology using DNS load balancing
Scaled Consolidated Edge topology using hardware load balancing (No Nat)
DNS A records for the __ interfaces of each Edge server in the perimeter network.
DNS A records for the __ interface of each reverse proxy server in the perimeter network, if needed.
Internal DNS
- DNS A and Service Location (SRV) records for auto configuration of the Edge __ interface of each Lync Server 2010 service that is available through the perimeter Edge network
- DNS A records for each ____ly visible simple URL
- DNS A records for the reverse proxy __ interface of each reverse proxy server in the perimeter network
External DNS
When automatic configuration for external client access or the PIC is used, specific DNS SRV records are required. These records act in the same way that a mail exchanger (MX) record provides the name of the correct mail Simple Mail Transfer Protocol (SMTP) server; for example:
- _sipexternaltls._tcp.fabrikam.com, 443, sip.fabrikam.com
- _sip._tls.fabrikam.com, 443, sip.fabrikam.com
- _sipfederationtls._tcp.fabrikam.com, 5061, sip.fabrikam.com
Refers to the ability and requirement for your external DNS and internal DNS servers to resolve DNS queries for the same host name to different host IP addresses and services,
Split Brain DNS
Use of a reverse proxy in your Edge server deployment is recommended if you must support:
federation, but it is required if you want to support sign-in of remote users.
Is now a unique server role located on an internal server or server pool in your internal network. It can serve as an internal next hop for inbound SIP traffic flowing from the Edge server to the internal destination servers.
The Director
______are required to support external user access to your Edge server deployment
Public certificates
