| Question ID 12881 | Which two mechanisms does Cisco EnergyWise use for neighbor discovery? (Choose
two.)
|
| Option A | multicast
|
| Option B | LLDP-MED
|
| Option C | UDP broadcast
|
| Option D | Cisco Discovery Protocol
|
| Option E | TCP
|
| Correct Answer | C,D |
Explanation Explanation: Cisco EnergyWise Neighbor Discovery Process The Cisco EnergyWise neighbor discovery process is the mechanism by which domain members discover each other and populate their Cisco EnergyWise neighbor tables. Cisco EnergyWise queries can subsequently be distributed to all domain members using the neighbor relationships to monitor and control the power usage of devices within a domain. Cisco EnergyWise domain members automatically discover their neighbors through one of two mechanisms: ✑ Cisco EnergyWise UDP broadcast packet ✑ Cisco EnergyWise CDP packets UDP broadcast packets are automatically sent out switch ports which support Cisco EnergyWise, regardless of whether the interfaces are configured with the no energywise interface-level command. CDP packets are sent when CDP is configured for the switch ports.

| Question ID 12882 | Which statement about the Cisco UC on UCS TRC and the third-party server specs-based
virtualization support model is true?
|
| Option A | Both the UC on UCS TRC and the third-party servers spec-based support models have rule-based approaches.
|
| Option B | The UC on UCS TRC support model has a rule-based approach and the third-party servers spec-based support model has a configuration-based approach.
|
| Option C | The UC on UCS TRC support model requires a high level of virtualization experience while the third-party server spec-based support model requires a low to medium level virtualization experience.
|
| Option D | VMware vCenter is mandatory for the UC on UCS TRC support model but it is optional for the third-party server spec-based support model.
|
| Option E | VMware vCenter is optional for the UC on UCS TRC support model but it is mandatory for the third-party server spec-based support model.
|
| Correct Answer | E |
Explanation Explanation: VMware vCenter is ✑ optional when deploying on UC on UCS Tested Reference Configuration hardware ✑ mandatory when deploying on UC on UCS Specs-based and Third-party Server Specs-based hardware. ✑ vCenter Statistics Level 4 logging is mandatory so that Cisco TAC is able to provide effective support. ✑ Click here for how to configure VMware vCenter to capture these logs. If not configured by default, Cisco TAC may request enabling these settings in order to provide effective support. ✑ Also note that enablement of specific VMware vSphere management features may require vCenter and/or a higher feature Edition of vSphere ESXi. ✑ Cisco Collaboration does not require its own dedicated vCenter. ✑ Note that when VMware vCenter is not required and is not used, then VMware vSphere ESXi's default management interface is its free/included VMware vSphere Client (formerly branded VI Client).
