Which two statements about the Cisco Unified Contact Center Enterprise clustering over the WAN deployment model are true? (Choose two.)

Question

Options

• AWith Cisco Unified Computing System C-Series Servers, you must deploy dual SAN on each data
• BThe visible network that supports the communication between Cisco Unified Communications
• CAgents at remote locations must be registered to only one data center for their Cisco Unified IP
• DCisco Unified Contact Center Enterprise IVR Peripheral Gateway cannot be split between the
• ECisco Unified Communications Manager Peripheral Gateways that are split between the two data

• A
  7% (3)
• B
  77% (33)
• C
  14% (6)
• D
  2% (1)

Explanation

Options B and E are correct because, in the UCCE Clustering over WAN (CoW) model, the inter-data-center network supporting communication between Cisco Unified Communications Manager nodes must meet strict latency requirements (B), and Cisco UCM Peripheral Gateways can be split between the two data centers to provide redundancy - with side A in one site and side B in the other (E). These two facts define the core design constraints and capabilities of the CoW model.

Option A is wrong because dual SAN is not a mandatory requirement for C-Series server deployments in a CoW environment. Option C is wrong because agents are not forced to register to a single data center - the CoW model allows flexible registration across both sites for resilience. Option D is wrong because IVR PGs are not categorically prohibited from any split configuration; the actual constraint is more nuanced and specific to UCM PG behavior.

Memory tip: Think of CoW as "split everything that can be split" - the two truths both involve what crosses the WAN: the network requirements (B) and the PG split behavior (E). If an answer choice says agents or components are locked to one site, it's likely wrong, since geographic redundancy is the whole point of CoW.
