Question 31
Refer to the exhibit.
As shown in the figure, DUT stands for the device under test and RTA is used to support the test.What is the correct procedure of a fast convergence test? ( )
1. Read data from the tester, record the numbers of sent and received packets, and count the number of lost packets.2. Switch the DUT-to-RTA background traffic to the link whose metric value is 100.3. DUT-to-RTA background traffic is forwarded along the link whose metric value is 10.4. Use the tester to advertise 10K routes to RTA and inject 10K flows to the DUT (each flow takes one route).5. Remove the optical fiber (providing a link whose metric value is 10) from the tester.6.
Calculate the convergence time based on the number of lost packets and packet sending rate.7.
Stop forwarding traffic when the packet receiving rate is equal to the packet sending rate.

Question 32
Exhibit.
As shown in the figure, inter-AS VPN Option A is used. CE 1 and CE 2 belong to the same VPNAS 100 and
AS 200 run IGP and LDP, respectively.
ASBRs communicate with each other through EBGP. the loopback interface address of CE 1 is 10.1.1.1/24
Suppose VPNs configured on the PE and ASBR are both named vpn-1 and CE 2 can ping CE1. Which
command can be ruin on ASBR 2 to find out route 10.1.1.1/24?
