Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q386-Q391):

NEW QUESTION # 386
SA (Security Association) is a parameter that must be negotiated when an IPsec tunnel is established, so which of the following parameters is used to uniquely identify SA? (Multiple choice)

Answer: A,B,C,D,E,F


NEW QUESTION # 387
The following figure shows the OSPF network of an enterprise and the OSPF configurations of R1. Which of the following statements is false about the network?

Answer: A

Explanation:
Silent Interface Explanation
The silent-interface command is used to prevent OSPF from sending or receiving OSPF packets on the specified interface (GE 0/0/1). This disables OSPF adjacency establishment and stops route advertisement for that interface.
Network Observations
Statement A: R2 can access the server.This is correct, as the silent interface does not impact data traffic, only OSPF-related communication.
Statement B: GE 0/0/1 of R1 cannot send OSPF packets.Correct due to the silent-interface configuration.
Statement C: The network segment to which GE 0/0/1 of R1 belongs cannot be advertised.This is correct, as the silent interface prevents route advertisement.
Statement D: GE 0/0/1 of R1 cannot accept OSPF packets.Correct, as the silent interface configuration blocks packet reception.
HCIP-Datacom-Core Reference
OSPF interface command behavior is outlined in the configuration and lab examples sections.


NEW QUESTION # 388
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: A

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 # 389
Which of the following is not a feature of OSPF?

Answer: D


NEW QUESTION # 390
In the OSPF protocol, inter-area route calculation involves only Router LSA, Network LSA, and Summary LSA.

Answer: A

Explanation:
Inter-area route calculation in OSPF involves Summary LSAs (Type 3) for summarizing routes across areas and ASBR Summary LSAs (Type 4) for locating ASBRs. While Router LSAs and Network LSAs describe the internal structure of an area, they do not directly participate in inter-area route calculation. Thus, the statement that only Router, Network, and Summary LSAs are involved is false .
