Explanation
Contoso must minimize hardware and software purchasing costs, while guaranteeing performance levels for all Lync Server 2013 workloads.
If a single component fails, all Lync services must remain available without the need for manual intervention. Performance degradation is acceptable during a component failure state.
For the number of users, 3 FE servers are required. In the event of a failure, one server could not handle 15,000 users.
SQL mirroring is the recommended database HA solution in Lync 2013. To avoid manual intervention, you need a third server to act as a witness server. You could use a failover cluster using two servers but this tends to be more expensive in terms of hardware cost.

Answer:
Explanation
Box 1: the Access Edge service Box 2: the A/V Edge Service Box 3: a reverse proxy
Note:
* The Edge Servers send and receive network traffic for the services offered by internal deployment by external users. The Edge Server runs the following services:
/Access Edge service The Access Edge service provides a single, trusted connection point for both outbound and inbound Session Initiation Protocol (SIP) traffic.
/Web Conferencing Edge service The Web Conferencing Edge service enables external users to join meetings that are hosted on your internal Lync Server 2013 deployment.
/A/V Edge service The A/V Edge service makes audio, video, application sharing, and file transfer available to external users. Your users can add audio and video to meetings that include external participants, and they can communicate using audio and/or video directly with an external user in point-to-point sessions. The A/V Edge service also provides support for desktop sharing and file transfer.
Authorized external users can access the Edge Servers in order to connect to your internal Lync Server 2013 deployment, but the Edge Servers do not provide a means for any other access to the internal network.
* the A/V Edge servers are able to accept connections for peer-to-peer calls and conference calls.
* The Reverse Proxy server is an optional, external component that is not a Lync Server role and is not defined in the Lync Topology. The reason this component is considered optional is because without it deployed an external Lync client can still connect to Lync and most features will function (IM, Presence, Calls, Desktop Sharing, etc) as will federated communications.
The reverse proxy is required for the following:
To allow users to connect to meetings or dial-in conferences using simple URLs
To enable external users to download meeting content
To enable external users to expand distribution groups
To allow the user to obtain a user-based certificate for client certificate based authentication
To enable remote users to download files from the Address Book Server or to submit queries to the Address Book Web Query service
To enable remote users to obtain updates to client and device software
To enable mobile devices to automatically discover Front End Servers offering mobility services
To enable push notifications to mobile devices from the Office 365 or Apple push notification services
Q39. You support a customer whose network environment includes Skype for Business Server 2015 deployed in a datacenter that has two pools, named PoolA and PoolB .

You run the Invoke-CsPoolFailover PowerShell cmdlet and you receive the following message:
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.
