Cisco Implementing Cisco Unified Communications Voice over IP and QoS v8.0 (CVOICE v8.0) Sample Questions:

1. Which feature can be used to avoid traffic congestion by dropping low-priority packets rather than dropping high-priority packets and is not recommended for voice networks?

A) class-based weighted fair queuing
B) low latency queuing
C) weighted random early detection
D) tail-drop

2. How are firmware images implemented and which file type describes the contents of the firmware image?

A) Firmware images are implemented as file bundles that are described by a file that ends with a .loads suffix.
B) Firmware images are implemented as a file loader group and are described by a file that ends with a .sbn suffix.
C) Firmware images are implemented as individual files that are described by a file that has a .loads suffix.
D) Firmware images are implanted as firmware groups that are described by a file that has a .cnf suffix.

3. Which statement about the DiffServ model is true?

A) DiffServ specifies a mechanism for classifying and managing network traffic and providing QoS on modern IP networks.
B) DiffServ is a way to provide the assurance of sufficiently low delay and packet loss for certain types of applications or traffic.
C) DiffServ is based on building a virtual circuit in the Internet using the bandwidth reservation technique.
D) DiffServ provides traffic management using QoS classifications.

4. You have a Cisco Unified Border Element configured to provide H.323 to SIP interworking. Which command will verify that you have a single H.323 and a single SIP call leg when the call is placed?

A) debug voip ipipgw
B) show dialpeer voice
C) show call active voice
D) debug voice dialpeer

5. In a voice gateway, the configured codec complexity of the DSPs on a voice card can be changed. What is the impact on the DSPs if high codec complexity is configured?

A) Lower codec complexity supports the fewest number of voice channels, provided that the lower complexity is compatible with the particular codecs that are in use.
B) The DSP will process codecs that support high complexity transparently and shift to flex mode for those codecs that are not high complexity.
C) With higher codec complexity, more calls can be processed.
D) The codec complexity affects call density, which is the number of calls that are reconciled on the DSPs. This results in lower call density when high complexity is configured.
