H12-831 practice questions, page 9 of 24, with answer review and explanations.

Question 41

As shown in the figure:

  1. There is Type 5 LSA flooding in Area2
  2. There is no Type 3 LSA flooding in Area2
  3. There is Type 5 LSA flooding in Area1
  4. There is no Type3 LSA flooding in Area1

Question 42

As shown in the figure:

  1. IS-Leve1 of R3 and R1 do not match
  2. R3 and R1 have different area codes
  3. The IIH certification of R3 and R1 failed
  4. The System ID of R3 and R1 are duplicated

Question 43

OSPFv2 is an IGP running on an IPv4 network; OSPFv3 is an IGP running on an IPv6 network. The basic working mechanism of OSPFv3 is the same as OSPFv2, such as the election of DR and BDR. As shown in the figure, an engineer uses three routers to test IPv6 services. He wants to realize the interconnection and interoperability of IPv6 networks by running OSPFv3. Which of the following statements regarding the election of DR on this network is correct?

  1. After the network converges, the engineer changes the priority of R1 to 100, the priority of R2 to 10, and the default value of R3. When the network converges again, R1 is DR and R2 is BDR
  2. After the network converges, a new device R4 is added to the broadcast link, and the priority of R4 is 150. When the network converges again, R4 is the DR
  3. After the network converges, R1 is powered off and restarted. When the network converges again, R3 is the DR
  4. After the network converges, R1 is the DR

Question 44

As shown in the figure, the cost value of the link that all interfaces of the router enable OSPF is identified in the figure. Loogback0 interfect of R2 is advertised in area 0. In area 1, both R2 and R3 will be transmitted in the form of Typae3 LSA 10.0.2.2/32 routing information.

  1. TRUE
  2. FALSE

Question 45

An enterprise purchased the leased lines of two operators. In order to optimize the route, the enterprise used the 6GP protocol to learn routing entries of the two operators. However, the company found that after such a configuration, the traffic of the export routing increased greatly. After the network engineering investigation, it was found that the traffic of the two operators was passed to each other through the company's export router. Therefore, the company intends to use routing strategies to prevent the traffic between different operators from passing each other. Is the configuration in the figure correct?

  1. TRUE
  2. FALSE
