An engineer is adding a third-party video endpoint to Cisco Unified Communications
Manager. Which third-party device type should be used when adding the system?

User A notices echo on a call with user B. Both users are using Cisco VoIP phones. User B is
using a headset, and user A is using a handset. What is the most likely source of the echo?

An engineer must configure QoS for a VoIP network. Which option is the best QoS model for
this task?

What is the recommended maximum one-way latency for voice and video networks?

Which two tools can be used to measure the quality of a VoIP call? (Choose two.)

Which Cisco Unified Communications Manager protocol communicates with collaboration
endpoints?

Client A in X site uses an IP phone to call client B in Y site. Engineers have selected SCCP
as the default VoIP signaling protocol. Which network path will the call signaling take when
client A calls client B?

Which four devices can be used to provide analog ports, traditional phones, and fax
machines? (Choose four.)

Which command allows the telephony service of a Cisco Unified Communications Manager
Express router to be associated to loopback address 192.168.143.44?

A network engineer receives a report about poor quality on an active call between the IP
phone of user A over the WAN to the IP phone of user B. Using web access to the phone, the
network engineer remotely checks call statistics such as jitter, network delay, and packet loss.
Calculated packet loss is 3%, average jitter is 20 ms, network delay is 1 ms, and conceal
seconds is 7.
What is the most likely problem with this call?
