Demo Questions

Question 1
All 50 employees in a company have Cisco IP phones. One employee notices high latency (more than 250 ms one way) on the IP network. How might this latency impact the employees when they try to make an outgoing phone call?

  • A: The voice quality cuts in and out
  • B: The call fails with a busy signal
  • C: The voice quality sounds like it is under water
  • D: The conversation has delays and interruptions
Correct Answer: D



Question 2
Which protocol is used to supply collaboration devices which can be used to monitor active voice call quality?

  • A: STP
  • B: SDP
  • C: QoS
  • D: RTCP
  • E: RTP
Correct Answer: D



Question 3
Which three pieces of information are provided to the Cisco phone by the DHCP server after a reset has been initiated? (Choose three.)

  • A: default gateway
  • B: dial tone
  • C: ARP table
  • D: SIP proxy server
  • E: IP address
  • F: TFTP servers
Correct Answer: AEF
The DHCP response contains the phone IP address and the IP address of the TFTP server (which is usually a Cisco CallManager server). The response can also contain any of or all these common options:
IP address of the default router (gateway) 
IP address of the Domain Name System (DNS) server 
Domain name

Question 4
Which signaling method uses robbed bit signaling?

  • A: CAS
  • B: FXS
  • C: FXO
  • D: CCS
Correct Answer: A
Reference: https://en.wikipedia.org/wiki/Robbed-bit_signaling



Question 5
Which option is the Cisco recommended maximum jitter value of voice traffic over the network?

  • A: 50 ms
  • B: 60 ms
  • C: 40 ms
  • D: 30 ms
Correct Answer: D
Voice calls, either one-to-one or on a conference connection capability, require the following:
≤ 150 ms of one-way latency from mouth to ear (per the ITU G.114 standard) 
≤ 30 ms jitter 
≤ 1 percent packet loss 
17 to 106 kbps of guaranteed priority bandwidth per call (depending on the sampling rate, codec, and Layer 2 overhead) 
150 bps (plus Layer 2 overhead) per phone of guaranteed bandwidth for voice control traffic

Question 6
In which three ways does QoS provide better network service VoIP quality? (Choose three.)

  • A: minimizes priority queuing
  • B: manages network congestion
  • C: improves loss characteristics
  • D: supports dedicated bandwidth
  • E: decreases traffic priorities
  • F: increases packet size
Correct Answer: BCD
In general, QoS provides better (and more predictable) network service by providing the following features:
Supporting dedicated bandwidth 
Improving loss characteristics 
Avoiding and managing network congestion 
Shaping network traffic 
Setting traffic priorities across the network

Question 7
In which two ways does QoS provide better network service VoIP quality? (Choose two.)

  • A: minimizes priority queuing
  • B: increases packet size
  • C: decreases traffic priorities
  • D: manages network congestion
  • E: improves loss characteristics
Correct Answer: DE



Question 8
Which option is the Cisco recommended mechanism for delivering voice payload?

  • A: IntServ
  • B: DiffServ
  • C: Policing
  • D: Shaping
Correct Answer: B



Question 9
Which two choices best describe call signaling and media flows? (Choose two.)

  • A: A process used to connect two parties calling
  • B: Audio or video or both transferred between two parties during conversation
  • C: Protocol for end-to-end users
  • D: A flow of audio and instant messaging
  • E: All call control signals being delivered through a channel
  • F: Data telephony, over a data network such as the Internet
Correct Answer: AB



Question 10
What is the maximum number of digits that an ephone PIN can have to allow after-hour exempt calling privileges?

  • A: 4
  • B: 6
  • C: 7
  • D: 8
  • E: 9
Correct Answer: D
