What is required to get one way delay measurements?
- A.
An MPLS network
- B.
The units must be synchronized
- C.
Latency in one direction
Correct Answer
B. The units must be synchronizedExplanation
To obtain one-way delay measurements, it is crucial for the units involved in the measurement process to be synchronized. This synchronization ensures that the timekeeping between the units is consistent, allowing for accurate measurement of the delay in one direction. Without synchronization, the measurements may be unreliable and inconsistent. Therefore, synchronization is a necessary requirement for obtaining accurate one-way delay measurements.Rate this question:

What is the traffyc type used for RFC2544,traffic generator and Y.1564 testing when testing a L3 network?
- A.
Generic traffic
- B.
UDP
- C.
TCP
- D.
All the above can be used
Correct Answer
B. UDPExplanation
UDP (User Datagram Protocol) is the correct answer for this question. When testing a Layer 3 network using RFC2544, traffic generator, and Y.1564 testing, UDP is commonly used as the traffic type. UDP is a connectionless protocol that does not provide reliable delivery of data, making it suitable for generating traffic in network testing scenarios. TCP (Transmission Control Protocol) is a connection-oriented protocol that provides reliable and ordered delivery of data, so it is not typically used for generating test traffic. "All the above can be used" is not the correct answer as TCP is not commonly used in this context.Rate this question:
