Huawei Sample Questions (Q79-Q84):

NEW QUESTION # 79
This configuration is part of RTA configuration. Which of the following statements regarding the configuration are true?
[RTA] ospf 100
[RTA-ospf-100]silent-interface GigabitEthernet 1/0/0

  • A. This interface cannot send Hello packets.
  • B. GigabitEthernet 1/0/0 is prohibited from sending OSPF packets.
  • C. RTA cannot establish a neighbor relationship with the neighbor that this interface is directly connected to.
  • D. Direct routes of GigabitEthernet 1/0/0 can still be advertised.

Answer: A,B,C

Explanation:
The silent-interface command disables the sending of OSPF packets, including Hello packets, on the specified interface, which prevents the establishment of OSPF neighbor relationships. However, the interface can still advertise directly connected routes through other interfaces, making Option C incorrect .


NEW QUESTION # 80
To prevent inter-area routing loops, OSPF does not allow advertising routing information between two non- backbone areas and allows sing routing information only within an area or between the backbone area and a non-backbone area. Therefore, each ABR must be connected to the backbone area.

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
OSPF (Open Shortest Path First) mandates that the backbone area (Area 0) serves as the central area for routing information exchange. To avoid inter-area routing loops, routing information is only exchanged between the backbone area and non-backbone areas, not directly between two non-backbone areas.
Consequently, each Area Border Router (ABR) must connect to the backbone area to facilitate this routing exchange .


NEW QUESTION # 81
Which command is used to configure the VRRP preemption delay?

  • A. vrrp vrid 1 preempt-timer 20
  • B. vrrp vrid 1 preempt-mode timer delay 20
  • C. vrrp vrid 1 timer delay 20
  • D. vrrp vrid 1 preempt-delay 20

Answer: D

Explanation:
The correct command for configuring the VRRP (Virtual Router Redundancy Protocol) preemption delay is vrrp vrid 1 preempt-delay 20. This command sets the delay before a higher-priority VRRP router preempts the master role, ensuring stable operation during network transitions .


NEW QUESTION # 82
Which three transmission modes are supported for IPv4 packets?

  • A. Unicast
  • B. Broadcast
  • C. Anycast
  • D. Multicast

Answer: A,B,D

Explanation:
IPv4 supports three main transmission modes:
* Unicast: One-to-one communication.
* Broadcast: One-to-all communication within a network.
* Multicast: One-to-many communication to a group of interested receivers.Anycast is not a native IPv4 mode but is introduced in IPv6 .


NEW QUESTION # 83
Match the following IPv4 multicast protocols with the corresponding functions.

Answer:

Explanation:

Explanation:
IGMP: Manages IPv4 multicast group members and runs on the multicast network's last segment (that is, the network segment where a Layer 3 network device is connected to user hosts).
PIM: Sends multicast data over the network to the multicast device that is connected to group members that have requested the multicast data, implementing multicast data forwarding based on routes.
IGMP Snooping: Manages and controls the forwarding of multicast data packets to effectively suppress the flooding of multicast data packets on the Layer 2 network.
IGMP (Internet Group Management Protocol):
* IGMP is used by hosts and adjacent multicast routers to establish and maintain multicast group memberships on a local subnet.
* It allows a host to inform a multicast router of its desire to receive multicast traffic for a specific group.
* It operates at Layer 3 and runs on the last segment of the network.
