Huawei Huawei Certifications H12-811 Questions & Answers

• Question 751:

  The data link layer uses PPP encapsulation. The IP addresses of the two ends of the link can be in different network segments.

  A. True

  B. False

  Correct Answer: A

• Question 752:

  Assuming that OSPF has been enabled on all routers in the following figure, which router is the BDR on this network?

  

  A. Router A

  B. Router B

  C. Router C

  D. Router D

  Correct Answer: A

  The BDR (Backup Designated Router) is then elected based on the second highest OSPF priority or second highest Router ID if there is a tie in OSPF priority among remaining routers after DR election. So in this case, after Router A is elected as the DR, Router B would be elected as the BDR because it has the second highest OSPF priority and second highest Router ID among remaining routers.

• Question 753:

  Which of the following statements about the functions and packet encapsulation of the ARP protocol is true?

  A. The ARP cache on a network device can be obtained only through the ARP protocol.

  B. The MAC address and UUID of the destination device can be obtained through ARP.

  C. ARP can be deployed on PPP and HDLC links.

  D. ARP packets are encapsulated over Ethernet.

  Correct Answer: D

• Question 754:

  An authenticator router has been configured with two domains named "Area1" and "Area2", following which a user is created with the username "huawei" and the password "hello" for authentication. Which domain does this user belong to?

  A. Area1 domain

  B. Area2 domain

  C. default domain

  D. default_admin domain

  Correct Answer: B

• Question 755:

  IPv6 uses NS and NA packets to perform duplicate address detection (DAD).

  A. True

  B. False

  Correct Answer: A

  IPv6 uses Neighbor Solicitation (NS) and Neighbor Advertisement (NA) packets to perform Duplicate Address Detection (DAD). DAD is used to ensure that no two devices on the same network have the same IPv6 address.

• Question 756:

  A network administrator wishes to implement VLAN 10 to isolate certain users. It is common however for these users to often change their physical location. Which of the following VLAN implementations should be used?

  A. Port based VLAN assignment.

  B. Protocol based VLAN assignment.

  C. MAC based VLAN assignment.

  D. IP subnet based VLAN assignment.

  Correct Answer: C

  With MAC based VLAN assignment, the switch assigns a VLAN to a device based on its MAC address. This means that even if the user changes their physical location and connects to a different port on the switch, they will still be assigned to the same VLAN because their device's MAC address remains the same.

• Question 757:

  Refer to the following display vlan command output on SWA. Which one of the following interfaces can forward untagged data frames from VLAN 40?

  

  A. GE0/0/2

  B. GE0/0/3

  C. GE0/0/4

  D. GE0/0/5

  Correct Answer: D

  Based on the information provided in the display vlan command output on SWA, the interface that can forward untagged data frames from VLAN 40 is D. GE0/0/5. In the command output, we can see that VLAN 40 has one interface configured as untagged (UT), which is GE0/0/5. This means that any data frames received on this interface without a VLAN tag will be treated as belonging to VLAN 40 and will be forwarded accordingly.

• Question 758:

  The tracert diagnostic tool of Huawei routers is used to trace data forwarding paths.

  A. True

  B. False

  Correct Answer: A

• Question 759:

  Which of the following port states is not included in Rapid Spanning Tree Protocol (RSTP)?

  A. Forwarding

  B. Learning

  C. Discarding

  D. Blocking

  Correct Answer: D

• Question 760:

  Refer to the following configuration of an interface on a switch. For witch VLAN does the interface transmit tagged data frames? # interface GigabitEthernet0/0/1 port hybrid tagged vlan 2 to 3 100 port hybrid untagged vlan 4 6 #

  A. 1, 2, 3, 100

  B. 2, 3, 100

  C. 2, 3, 4, 6, 100

  D. 1, 2, 3, 4, 6, 100

  Correct Answer: B
