Demo Questions

Question 1
Which statement about the Cisco UC on UCS TRC and the third-party server specs-based virtualization support model is true?

  • A: Both the UC on UCS TRC and the third-party servers spec-based support models have rule-based approaches.
  • 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.
  • 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.
  • 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.
  • 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.



Question 2
Which definition is included in a Cisco UC on UCS TRC?

  • A: required RAID configuration, when the TRC uses direct-attached storage
  • B: configuration of virtual-to-physical network interface mapping
  • C: step-by-step procedures for hardware BIOS, firmware, drivers, and RAID setup
  • D: configuration settings and patch recommendations for VMware software
  • E: server model and local components (CPU, RAM, adapters, local storage) by name only; part numbers are not included because they change over time



Question 3
Which capability is supported by Cisco Discovery Protocol but not by LLDP-MED?

  • A: LAN speed and duplex discovery
  • B: Network policy discovery
  • C: Location identification discovery
  • D: Power discovery
  • E: Trust extension



Question 4
Which two mechanisms does Cisco EnergyWise use for neighbor discovery? (Choose two.)

  • A: multicast
  • B: LLDP-MED
  • C: UDP broadcast
  • D: Cisco Discovery Protocol
  • E: TCP



Question 5
Which statement describes a disadvantage of using the Cisco TFTP service to serve IP phone load files?

  • A: The Cisco TFTP services can run on only one Cisco Unified Communications Manager server in a cluster.
  • B: Because TFTP operates on top of UDP, there is a high risk of corrupted load file delivery at the completion of the TFTP process due to undetected data loss in the network.
  • C: If a response is not received in the timeout period, the TFTP server will not resend the data packet.
  • D: Packet loss can significantly increase the TFTP session completion time.
  • E: Because TFTP operates with an adaptive timeout period, the time to complete the file transfer is unpredictable.



Question 6
Which two statements about the Peer Firmware Sharing option for IP phone firmware distribution are true? (Choose two.)

  • A: This option uses a parent-child hierarchy in which a firmware image is downloaded by a parent phone to up to three directly associated child phones.
  • B: This option must be enabled on Cisco Unified Communications Manager service parameters for Cisco TFTP.
  • C: This option mandates that the parent phone and child phones be identical, selected phone models.
  • D: This option allows firmware transfers between phones in different subnets, as long as the round-trip delay is less than 5 milliseconds.
  • E: This option uses a parent-child hierarchy that must be manually defined by the Cisco Unified Communications Manager administrator.
  • F: This option allows falling back to the TFTP server in the Cisco Unified Communications Manager cluster.



Question 7
Which capability is support by LLDP-MED but not by Cisco Discovery Protocol?

  • A: LAN speed discovery
  • B: network policy discovery
  • C: location identification discovery
  • D: power discovery
  • E: trust extension



Question 8
In a Cisco EnergyWise domain, which two terms describe a Cisco IP phone? (Choose two.)

  • A: endpoint
  • B: domain member
  • C: child domain member
  • D: EnergyWise agent
  • E: Cisco power distribution unit



Question 9
Which statement about Cisco EnergyWise domain member neighbor formation is true?

  • A: Cisco EnergyWise supports static neighbors, but the neighbor relationship is only possible if a noncontiguous domain member and a contiguous domain member have a static neighbor entry pointing to each other.
  • B: Cisco EnergyWise static neighbors can be formed even if domain members are not physically contiguous.
  • C: Static neighbors can be manually defined on Cisco EnergyWise domain members, but TCP protocols must be used.
  • D: Static neighbors can be manually defined on Cisco EnergyWise domain members, but they have a lower priority compared to the autodiscovered members.
  • E: Static neighbors can be manually defined on Cisco EnergyWise domain members and the TCP or UDP protocol can be used.



Question 10
Refer to the exhibit. 

  
  
Assuming that the administrator has never performed any manual custom uploads, which two file types can be found when you choose Software Upgrades, followed by TFTP File Management on the Cisco Unified Operating System Administration web page for Cisco Unified Communications Manager? (Choose two.)

  • A: IP phone configuration files
  • B: announcement audio files
  • C: ringer files
  • D: IP phone license files
  • E: sample music-on-hold audio files
  • F: softkey template files
