Huawei H12-831 Online Questions & Answers

• Question 1:

  On the network shown in the figure, EBGP peer relationships are established between neighboring routers through directly connected interfaces.

  The router ID of each router is 10.0.X.X, and the AS number is 6500X, where X is the number of the router.

  Both R1 and R4 have static routes to 192.168.1.0/24, which are imported to BGP through the import-route command.

  R1 adds a community attribute (1:1) to the route before advertising it to its peers. All routers are configured to propagate community attributes. R3 is configured with a routing policy that rejects routes with the community attribute 1:1.

  

  In this case, which of the following is the path for traffic from R3 to 192.168.1.0/24?

  A. R3 R2 R4
  B. R3 does not have a route to 192.168.1.0/24
  C. R3 R2 R1
  D. R3 R5 R1
  D. R3 R5 R1

• Question 2:

  Qing technology is a technology to expand VLAN space. It can achieve the function of expanding Vian space by adding a layer of 8D2.1Q Tag on the basis of 8Q2.12 tag message. Which of the following statements about qinq is false?

  A. flexibleQinQAccording to different inner layersTagwith different outer layersTag,correct to the userVLANThe division is more detailed
  B. QinQMakeVLANincreased to4095*4095
  C. QinQtechnology enables private networksLANTransparent transmission on the public network
  D. basicQinQbased on the interface
  B. QinQMakeVLANincreased to4095*4095

• Question 3:

  On the network shown in the figure, EBGP peer relationships are established between ASs through directly connected interfaces.

  OSPF is deployed in AS 65456 (with OSPF disabled on interconnected interfaces between ASs).

  R4 and R5 use Loopback0 to establish iBGP peer relationships with R6. The IP address of Loopback0 on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router.

  R1, R2, and R3 import the external route 192.168.1.0/24 into BGP through the import-route command.

  

  Which of the following statements are true?

  A. For 192.168.1.0/24, R5 preferentially selects the route received from R2.
  B. For 192.168.1.0/24, R4 preferentially selects the route received from R1.
  C. For 192.168.1.0/24, if the default local-preference 150 command is configured on R3, R5 preferentially selects the route received from R3.
  D. For 192.168.1.0/24, R6 preferentially selects the route received from R4.
  A. For 192.168.1.0/24, R5 preferentially selects the route received from R2.
  C. For 192.168.1.0/24, if the default local-preference 150 command is configured on R3, R5 preferentially selects the route received from R3.
