Exam N10-007 topic 1 question 91 discussion

DSCP is correct. The differentiated services code point is a 6-bit entry in an 8-bit differentiated services field in an IP header. This is used to classify data and help manage QoS in a network. STP is incorrect; Spanning Tree Protocol is used to provide loop avoidance. VLANs is incorrect; Virtual LANs classify and break up a network into distinct broadcast domains but do not classify the data. SIP is incorrect; Session Initiation Protocol is used to construct and deconstruct multimedia sessions.

The correct answer is D. Quality of Service (QoS) DSCP Marking is used to determine traffic classification for network data. This can be used to determine which network traffic requires higher bandwidth, has a higher priority, and more likely to drop packets.

Differentiated services or DiffServ is a computer networking architecture that specifies a simple and scalable mechanism for classifying and managing network traffic and providing quality of service on modern IP networks. Differentiated services or DiffServ is a computer networking architecture that specifies a simple and scalable mechanism for classifying and managing network traffic and providing quality of service on modern IP networks.

The given answer is correct because QoS is associated with DiffServ, which is related to DSCP.

Is the answer b
