1. redundant hardware
2. 24-hour staffing
3. redundant links
4. proactive network management

3. Which response best describes the characteristics of VoIP traffic?

1. smooth and delay insensitive
2. bursty and delay sensitive
3. smooth and sensible to jitter
4. bandwidth greedy and delay sensitive

4. Which is the tolerable end-to-end delay for VoIP?

1. 30 ms
2. 60 ms
3. 150 ms
4. less than 1 second

5. Which is the function of a Call Processing Manager?

2. perform call setup and routing
3. provide extension number to new registering phones
4. all of the above

6. How does video traffic compare to VoIP traffic?

1. Video is bandwidth intensive, just like voice.
2. Video is delay sensitive, just like voice.
3. Video needs steady packet transmission, just like voice.

7. Which transport layer protocol does VoIP use?

1. It uses TCP.
2. It uses ICMP.

10. Which protocol allows creating a CoS in the 802.1Q trunking protocol?

1. ISL
2. 802.1p

2. using access lists
3. using resource reservation code points
4. using DSCPs
