Answer: CHKP
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.
