Huawei H31-161 Actual Free Exam Questions & Community Discussion

Refer to the exhibit.

As shown in the figure, CE 1 and CE 2 belong to VPN A, both LDP and
TE tunnels are configured between PE 1 and PE 2, the QPPB feature is configured on PE 2, and a tunnel policy is configured and applied to VPNs under PE 2 to make TE tunnels be preferred.
11.11.11.11/32 is a static route on CE 1 and is learned by CE 2. CE 2, however, fails to apply resource isolation VPN to PE 2. What is the possible cause?

Refer to the exhibit.

As shown in the figure, inter-AS VPN Option A is used. CE 1 and CE 2 belong to the same VPN.AS 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 CE 2 can ping CE 1. Which router allocates an inner label when PE 2 forwards packets from CE 2 to CE
1?

On the IP bearer network, different VPN users (VPN A and VPN B) must access the internet through the same egress. Which of the following schemes can achieve security isolation VPNs and have the best scalability?

As shown in the figure, MPLS, MPLS TE, and MPLS RSVP-TE are configured on RTA, RTB, RTC, and RTD. Tunnel1/0/0 and Tunnel2/0/0 are set up based on the explicit path RTA-RTB-RTC. Tunnel1/0/0 has a hot-standby path (RTA-RTD-RTC) and an FRR path: RTA-RTD-RTC, whereas Tunnel2/0/0 has an ordinary path (RTA-RTD-RTC) and an FRR path. Which of the following statements are true?

RTA is a leaf router that directly connects to host A through interface GigabiteEthernet 1/0/0. The interface is configured as follows:

Hos a sends a IGMPv2 Report message to group 2321.2.3. Which entry can be displayed by the displayed by the igmp ssm-mapping group command?

Which of the following reserved IP multicast addresses is the address of all PIM routers?

In the access architecture of an IP bearer network, the OSPF protocol is enabled between two access routers, two firewalls (in transparent mode), and two Layer 3 switches. Softswitches work in active/standby mode. VRRP is enabled between the softswitches to provide a gateway. In normalcases, SW1 is the master router and SW2 is the backup router. Considering the reliability of the access network, how would you plan the cost value of each link in the OSPF area?

With the SA, which of the following, option is correct?

Which of the following statements about the VPLS packet forwarding are true?

Which of the following methods can be used to ensure loop-free and reachable Martini VPLS links?

Which of the following statements about inter-AS VPN Option A are true? (ACE)

Which of the following is the maximum length of the Ethernet frame encapsulated by QinQ?

Based on the preceding configurations, which of the following statements about the mapping relationships between the specified group and the RP are true?

Exhibit:

As shown in the figure, RTA belongs to AS 100 and has an EBGP neighbor relationship with RTC, RTD, and TTB is an IBGP neighbor of RTC, RTD, and RTE, and the four router all belong to AS 200.
(Note: The attributed not involved In the question use the default values)
1. Import route 1.1.1/32 from RTA and advertise this route to RTB by way of RTC, RTD, and RTE, respectively (suppose the three routers between is IGP, EGP, and INCOMPL:ETE, respectively. Which route will RTB prefer?
2. Suppose the preceding policy is retained. Apply inbound routing policies on RTC, RTD, and RTE so that the values of the MED attribute of route 1.1.1.32 learned by RTB are 40, and 20 respectively. Which route will RTB prefer?
3. Suppose the preceding policy is retained. Apply an inbound routing policy on RTB so that the values of the AS_ PATH attribute of route 1.1.1.1/32 Learned from RTC, RTD, and RTE are 10 20 30,and 10 20, respectively. Which route will RTB prefer?
4. Suppose the preceding policy is retained. Apply an inbound routing policy on RTB so that the values of the local-preference attribute of route 1.1.1.1.32 learned from RTC and RTE are 30 and 120 , respectively. Which route will RTB prefer.
5. Suppose the preceding policy is retained. Apply inbound policies on RTC. RTD and RTE so that the values of the preferred-value attribute of route 1.1.1.132 are 50.40 and 30 respectively. Which route will RTB prefer?
