Requirements
Business Goal
Contoso plans to upgrade to Skype for Business Server 2015 during the next six months. Contoso must deploy all of the conferencing and edge services. Contoso must also configure federation with its parent company, which is named Proseware, Inc. Proseware is located in Europe and has a Lync Server 2010 infrastructure.
Contoso must minimize hardware and software purchasing costs, while guaranteeing performance levels for all Skype for Business Server 2015 workloads.
Planned Changes
Contoso plans to implement the following workloads in the Skype for Business Server 2015 deployment:
Federation
Dial-in conferencing
External user access
Audio, video, and web conferencing
The ability to host Lync meetings that have external participants
The FQDNs of the edge services will be configured as shown in the following table.
Technical Requirements

Only federation to Proseware must be allowed.
All of the edge services must use default ports.
Wide area network (WAN) traffic and Internet traffic must be minimized.
All of the user contacts stored in Skype for Business Server 2015 must be backed up.
The sales department must have a dedicated dial-in conferencing number. All other users in both the
United States and Europe must use a pool of regional dial-in conferencing numbers.
If a single component fails, all Skype for Business services must remain available without the need for
manual intervention. Performance degradation is acceptable during a component failure state.
The conversations of all the sales department users must be archived for 30 days. The conversations
of all the research department users must be archived for 90 days. No other conversations must be archived.
After the migration to Skype for Business Server 2015, all client computers will have three months to
upgrade to Skype for Business. After three months, legacy clients must be blocked from accessing the Skype for Business Server 2015 infrastructure.

All Skype for Business Server conferences must use a unique URL.
Each Internet-facing service must have one or more dedicated public IP addresses.
Only the users in the human resources department must be prevented from connecting to Skype for
Business Server 2015 remotely.
You need to identify the cause of the authentication issue for the pilot users.
