When comparing real-time application, such as VoIP with an interactive Web Browsing (HTTP) application. What is true about the requirement for the quality of service using such applications? (Choose three answers.)
Web Browsing requires less bandwidth
Web Browsing requires high packet reliability
Voice over IP requires lower packet loss
Voice over IP requires high packet reliability
Voice over IP requires lower packet delay
Web Browsing requires lower packet delay
TCP interactive applications such as HTTP or FTP require high reliability to function properly, while their delay, jitter and loss are not crucial as compared to UDP applications. A real-time application such as VoIP which uses UDP protocol, typically requires lower delay, jitter and loss as compared with all data applications. [VoIP can tolerate the occasional dropped packet. The entire point of UDP is that the data is not as reliable as TCP]
