The H31-161 exam contains 60-70 questions to be completed within 120 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the VCETorrent test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

returnUnder the preceding configurations, traffic cannot be distributed to the three tunnels. To implement load balancing, which of the following modifications are correct?
- A. Create a TE tunnel to 2.2.2.2 on PE 1.
- B. Delete policy 1 from PE 1.
- C. Create a GRE tunnel to 2.2.2.2 on PE 1.
- D. Delete policy 1 in the vpna instance view.
Correct Answer: A,B 🗳️
Question #2
As shown in the figure, RTA, RTB, and RTC use the OSPF protocol. The default cost value is used for links, and unicast routes converge on the entire network. The Loopback 0 interface is set to configure RTC as the RP or BSR. The SPT switching threshold uses the default value on RTB. The receiver joins the multicast group 225.1.1.1. The multicast source sends multicast data to the destination address 225.1.1.1. Which interface is the inbound interface in the (10.1.1.1, 225.1.1.1) entry on RTB?
- A. Ethernet 1/0/1
- B. Ethernet 1/0/0
- C. Null
- D. Ethernet 2/0/0
Correct Answer: B 🗳️
Question #3
Which multicast protocol can support the SSM? (
- A. IGMPv2
- B. BGP
- C. PIMSSM
- D. MLDv2
- E. OSPF
- F. IGMPv3
- G. PIMDM
Correct Answer: C,D,F 🗳️
Question #4
As shown in the figure, the costs of paths from RTA to RT 11, RT 12, RT
13, RT 14, and RT 15 are all 10 and the available bandwidth is 200 Mbit/s.
The costs of paths from RTB to RT 31, RT 32, RT 33, RT 34, and RT 35 are all 10 and the available bandwidth is 200 Mbit/s.
The costs of paths from RT 11 to RT 21 and from RT 21 to RT 31 are both 5. The available bandwidth is 200 Mbit/s.
The cost of the path from RT 12 to RT 32 is 5 and the available bandwidth is 120 Mbit/s. The cost of the path from RT 13 to RT 33 is 10 and the available bandwidth is 80 Mbit/s.
The cost of the path from RT 14 to RT 34 is 10 and the available bandwidth is 100 Mbit/s.
The cost of the path from RT 15 to RT 35 is 10 and the available bandwidth is 100 Mbit/s.
The load balancing rule of Constraint Shortest Path First (CSPF) is set to Random on RTA.
Which path will a 100 Mbit/s tunnel from RTA to RTB take?
- A. RTA-RT12-RT32-RTB
- B. RTA-RT14-RT34-RTB
- C. RTA-RT15-RT35-RTB
- D. RTA-RT11-RT21-RT31-RTB
- E. RTA-RT13-RT33-RTB
Correct Answer: B,C 🗳️
