A Cisco Unified Contact Center Enterprise system is designed with geographic redundancy for the
central controllers (with separate call routers and loggers). At the Side A location, there are Call
Router A, Logger A, and a duplex pair of peripheral gateways (PG1A/PG1B). At the Side B
location, there are Call Router B, Logger B, and a duplex pair of peripheral gateways
(PG2A/PG2B). The visible network WAN between the two sites goes down while the private
network is operational.
Which of these is true?
A.
The peripheral gateway pair at the Side A site (PG1A/PG1B) is unavailable.
B.
The Side A call router becomes active and the peripheral gateway pair at the Side B site
(PG2A/PG2B) becomes unavailable.
C.
Both pairs of peripheral gateways at both sites stay active and Call Router B takes control.
D.
Both pairs of peripheral gateways stay active at both sites because both call routers are still
communicating through the private connection and remain functional.
