You need to recommend a Web conferencing solution for the Lync Server 2010 servers in the main office. The solution must meet the companys availability requirements. What should you include in the recommendation?

A.
two Standard Edition servers configured to use hardware load balancing

B.
two servers in a Director pool configured to use Network Load Balancing (NLB)

C.
two servers in an Enterprise Edition Front End pool configured to use hardware load balancing

D.
two servers in an Enterprise Edition Front End pool configured to use DNS load balancing

Explanation:
[!] Need full case info. SE severs do not support clustering of any sort, and Director is not used for Web conferencing. Choice between DNSLB or HLB depends on legacy clients: rule of thumb – Lync only = DNSLB, Legacy = HLB. Still, HLB is a more robust solution usually, so you can use it everywhere you can if the budget permits.
