Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q231-Q236):

NEW QUESTION # 231
As shown in the figure, the user has configured the relevant parameters of the VRRP backup group, and the parameters that are not shown remain in the default state.

R3 with priority 240 is now added to the VRRP backup group. Which of the following descriptions are correct? (Multiple choice)

Answer: B,C


NEW QUESTION # 232
The Interface IP address and VRRP virtual IP address can be the same.

Answer: B

Explanation:
BFD control packets are encapsulated in UDP packets, and the destination port number for multi-hop BFD control packets is 4784. This is a standardized port for multi-hop BFD operation.


NEW QUESTION # 233
See the command output of a router below. Which of the following statements is true?
<R2>display ospf interface GigabitEthernet 0/0/0 verbose
OSPF Process 1 with Router ID 10.0.2.2
Interface: 10.0.12.2 (GigabitEthernet 0/0/0)
Cost: 1 State: BDR Type: Broadcast MTU: 1500
Priority: 1
Designated Router: 10.0.12.1
Backup Designated Router: 10.0.12.2
Timers: Hello 10 , Dead 40 , Poll 120 , Retransmit 5 , Transmit Delay 1

Answer: C

Explanation:
The output shows that the router with the IP 10.0.12.2 is the Backup Designated Router (BDR), as indicated in the State: BDR field. The router ID is 10.0.2.2, the interface cost is 1, and the IP address of the interface is
10.0.12.2. Hence, C is the correct answer .


NEW QUESTION # 234
An enterprise administrator configures route summarization on ASBRs to reduce the number of inter-area Type 3 LSAs, which in turn reduces the routing table size and improves device resource utilization.

Answer: B

Explanation:
OSPF Route Summarization:
Route summarization combines multiple specific routes into a single summary route. This reduces the number of LSAs advertised between OSPF areas, especially Type 3 LSAs.
Benefits of Route Summarization:
Reduces the size of the OSPF database and routing table.
Minimizes the processing overhead on routers by decreasing the number of routing entries.
Improves the scalability of the OSPF network.
ASBR Function:
The ASBR advertises external routes into OSPF and can summarize routes at area boundaries or during redistribution.


NEW QUESTION # 235
Depending on the type of algorithms used, routing protocols are classified into distance-vector protocols and link-state protocols.
Which of the following routing protocols are link-state protocols?

Answer: A,D

Explanation:
Distance-Vector Protocols:
Distance-vector protocols determine the best path based on the distance to a destination and periodically share the entire routing table with neighbors.
Example: RIP is a distance-vector protocol.
Link-State Protocols:
Link-state protocols share information about directly connected links, enabling routers to build a complete map of the network.
OSPF (Open Shortest Path First) and IS-IS (Intermediate System to Intermediate System) are link-state protocols that use Dijkstra's algorithm to calculate the shortest path.
Border Gateway Protocol (BGP):
BGP is neither a distance-vector nor a link-state protocol. Instead, it is classified as a path-vector protocol that selects the best path based on attributes such as AS-path, next-hop, and local preference.
