Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q71-Q76):

NEW QUESTION # 71
When creating a single-hop BFD session for the first time, bind the single-hop BFD session to the peer IP address and the local address. To modify a configured BFD session, delete it and create a new one.

  • A. TRUE
  • B. FALSE

Answer: A

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Single-Hop BFD Session:
* A single-hop BFD session is used to detect link failures between directly connected devices.
* It is bound to the local IP address and the peer IP address, and the session relies on these parameters to establish connectivity.
2. Why Modifications Require Deletion:
* BFD sessions are tightly bound to their configuration parameters (e.g., local and peer IP addresses).
* Modifying these parameters is not supported for an existing session. Instead, you must delete the session and recreate it with the updated parameters.
3. Why the Statement is TRUE:
* The statement correctly describes the behavior of BFD sessions, where modifying an existing session is not possible without deleting it first.


NEW QUESTION # 72
Which of the following statements about WLAN roaming are true?

  • A. APs for roaming must have overlapping signal coverage.
  • B. APs for roaming do not need to have overlapping signal coverage.
  • C. APs for roaming must be in the same basic service set (BSS).
  • D. APs for roaming must be in the same extended service set (ESS).

Answer: B


NEW QUESTION # 73
The figure shows the VRRP status switchover events. Match these events with their sequence numbers.

Answer:

Explanation:

Explanation:
1 # A Startup message with a priority of 255 is received.2 # A Startup message with a priority less than 255 is received.3 # A Shutdown message is received.4 # The Master_Down timer expires, an Advertisement packet with the priority of 0 is received, or a packet with a priority lower than the local priority is received.5 # A packet with a priority higher than the local priority is received.6 # A Shutdown message is received.
# Reference: Huawei HCIA-Datacom Study Guide, VRRP Status Transitions.


NEW QUESTION # 74
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.
HCIP-Datacom-Core Technology Training Material (Multicast Fundamentals).
PIM (Protocol Independent Multicast):
PIM is a routing protocol designed for efficient routing of IP multicast traffic. It determines the paths over which multicast packets should be forwarded.
PIM is "protocol-independent" because it uses the underlying unicast routing table for RPF (Reverse Path Forwarding) checks.
It is responsible for distributing multicast data throughout the network.
Reference:HCIP-Datacom-Core Technology Training Material (Multicast Routing Protocols).
IGMP Snooping:
IGMP Snooping operates at Layer 2 and monitors IGMP traffic between hosts and routers.
It prevents multicast flooding by allowing a switch to forward multicast packets only to the ports that have joined specific multicast groups.
This significantly enhances efficiency in Layer 2 networks with multicast traffic.
Reference:HCIP-Datacom-Core Technology Training Material (IGMP Snooping Concepts).


NEW QUESTION # 75
On a WLAN, engineers can use the VLAN pool mechanism to assign access users to different VLANs, which helps reduce the number of broadcast domains and improve network performance. VLAN pools support two VLAN assignment algorithms: even and hash. Drag the advantages and disadvantages to the two algorithms.
(Token is reusable)

Answer:

Explanation:
Explanation of VLAN Pool Assignment Algorithms:
In WLANs,VLAN poolshelp reduce broadcast domains and improve network performance by distributing users across multiple VLANs. Two algorithms are used for VLAN assignment:
Even Assignment Algorithm:
The number of users in each VLAN is even.
This algorithm assigns users evenly across VLANs, ensuring a balanced distribution of users in each VLAN.
When STAs go offline and online again, their VLANs and IP addresses may easily change.
Since the assignment is based on maintaining even distribution, a device (STA) may not be assigned the same VLAN when it reconnects, leading to potential IP address changes.
Hash Assignment Algorithm:
The number of users in each VLAN is uneven.
The hash algorithm assigns users to VLANs based on a hash value (e.g., derived from the MAC address). This may result in an uneven distribution of users across VLANs.
VLANs and IP addresses remain unchanged for STAs that go offline and online again.
The hash algorithm ensures that a device reconnects to the same VLAN, preserving its IP address.
