You plan to deploy an additional Edge Server. You need to recommend changes to the Lync Server infrastructure that meet the companys availability requirements for remote users. What should you include in the recommendation?
A.
hardware load balancing
B.
an additional Mediation Server and a PSTN gateway in each site
C.
a Director pool that contains two Directors
D.
DNS load balancing
Explanation:
[!] Ned full case info, but A and D both fit. 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.
