NEW QUESTION 9
Which subnet mask should you use on point-to-point links to avoid wasting IP addresses?

• A. 255.255.255.252
• B. 255.255.255.250
• C. 255.255.255.0
• D. 255.255.255.248

Answer: A

NEW QUESTION 10
What is the acceptable amount of one-way network delay for voice and video applications?

• A. 300 bytes
• B. 1 sec
• C. 150 ms
• D. 500 ms

Answer: C

Explanation: Delay Components in VoIP Networks
The ITU's G.I 14 recommendation specifics that the one-way delay between endpoints should not exceed 150 ms to be acceptable, commercial voice quality. In private networks, somewhat longer delays might be acceptable for economic reasons. The ITU G.114 recommendation specifics that 151-ms to 400-ms one-way delay might be acceptable provided that organizations are aware that the transmission time will affect the quality of user applications. One-way delays of above 400 ms are unacceptable for general network planning purposes.

NEW QUESTION 19
Which four services does the architecture for Media Services contain? (Choose four.)

• A. access services
• B. transport services
• C. storage services
• D. forwarding services
• E. session control services
• F. security services
• G. filtering services
• H. remote access services

Answer: ABCE

Explanation: An architecture framework for media services supports different models of video models. As shown in Figure 14-13, the network provides service to video media in the Media Services Framework. Those services are access services, transport services, bridging services, storage servers, and session control services, which arc provided to endpoints.
Access services provide identity of end devices, mobility, and location services. Transport services provide QoS for reliable packet delivery.
Bridging services provide transcoding, conferencing, and recording services of media streams.
Storage services provide capture and storage of media streams and content management and distribution. Session control services provide session signaling and control and gateway services.
