H12-261 Exam Question 197

Which of the following statements are true? (Multiple Choice)

A.Multicast technology can reduce redundant traffic and hence save network bandwidth.

B.Multicast technology can be used for all "one-to-many" data transmission applications.

C.Multicast technology can ensure reliable packet transmission because it is based on TCP connections.

D.Multicast use UDP to carry traffic instead of TCP.

H12-261 Exam Question 198

Router A has an IP route with the destination network segment of 10.0.0.1/32 and outbound interface of GigabitEthernet0/0/1. The following configuration is added:

Assume that router A receives a data packet with the destination IP address of 10.0.0.1.
Which of the following statements are true?

A.If the source IP address of the data packet is 10.0.1.2, the data packet can be forwarded and the DSCP value is set to CS3.

B.If the source IP address of the data packet is 10.0.1.2, the data packet can be forwarded and the DSCP value remains unchanged.

C.If the source IP address of the data packet is 10.0.1.1, the data packet can be forwarded and the DSCP value is set to CS3

D.If the source IP address of the data packet is 10.0.1.2, the data packet cannot be forwarded.

H12-261 Exam Question 200

A newly deployed HW router is configured for Weighted Random Early Discard (WRED) on the HW network. WRED has which of the folbwing characteristics? (Multiple Choice)

A.For packets of different priorities, WRED can set different packet drop thresholds and packet loss ratios.

B.Low bandwidth flows are experiencing packet drop at a higher rate than higher bandwidth flows.

C.When the minimum threshold is crossed, WRED begins dropping all incoming packets (tail-drop).

D.Global Synchronization is avoided by selectively dropping packets from multiple TCP fbws.
