Which two statements about a Contact Center Enterprise solution in virtualized environment are true? (Choose two.)

Question

Options

• AUCS B/C series NIC teaming is supported.
• B10/100 NIC speeds are supported.
• CGigabit Ethernet Auto Negotiation is optional for NIC and switch.
• D802.1Q uplinks to VMware hosts must not be configured for host/edge spanning-tree forwarding.

• A
  70% (14)
• B
  10% (2)
• D
  20% (4)

Explanation

A is correct because Cisco UCS B-series (blade) and C-series (rack) servers explicitly support NIC teaming in virtualized CCE deployments, providing the redundancy and throughput that contact center workloads demand.

C is correct because while Gigabit Ethernet is required, auto-negotiation between the NIC and the switch is optional - administrators may hardcode speed and duplex settings instead of relying on auto-negotiation, and both approaches are valid.

B is wrong because 10/100 Mbps NICs do not meet the minimum bandwidth requirements for virtualized CCE; Gigabit Ethernet (1 Gbps) is the floor, not an option.

D is wrong because it inverts the actual requirement: 802.1Q trunk uplinks to VMware hosts should be configured with PortFast/edge (host) spanning-tree mode to eliminate STP convergence delays when ports initialize - saying they "must not" be is the opposite of best practice.

Memory tip: Think "GigE or go home" - anything below 1 Gbps is out (eliminates B), and for spanning tree on VM host uplinks, always think "PortFast = faster" (eliminates D). UCS is Cisco's own virtualization platform, so full NIC teaming support (A) is a given.
