Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q59-Q64):

NEW QUESTION # 59
In the OSPF protocol, inter-area route calculation involves only Router LSA, Network LSA, and Summary LSA.

A. TRUE
B. FLASE

Answer: B

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 .

NEW QUESTION # 60
On an IS-IS network, each router can generate LSPs. Which of the following events trigger the generation of a new LSP?

A. Related IS-IS interfaces go up or down.
B. The IS-IS interface cost is increased.
C. Inter-area IP routes change.
D. Periodic updates occur.

Answer: A,B,D

Explanation:
LSP Generation in IS-ISIS-IS routers generate new Link State Packets (LSPs) under the following conditions:
* Interface Status Changes: When IS-IS interfaces go up or down, the link state changes, triggering LSP updates.
* Periodic Updates: IS-IS periodically regenerates LSPs to ensure link-state information remains synchronized across the network.
* Interface Metric Changes: Any modification to interface costs results in a new LSP to reflect the updated cost in the network.
Incorrect Option
* C. Inter-area IP routes change is incorrect because IS-IS does not inherently differentiate between areas for LSP generation.
HCIP-Datacom-Core Reference
* IS-IS LSP generation rules are detailed in the IS-IS configuration and implementation chapters.

NEW QUESTION # 61
OSPF networks are classified into broadcast, P2P, P2MP, and NBMA networks. Which of the following types of networks use the default Hello time (30s)?

A. P2MP
B. NBMA
C. P2P
D. Broadcast

Answer: A,B

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* Default OSPF Hello Timer:
* The OSPF Hello timer is used to send periodic Hello packets and maintain neighbor relationships.
* Default Hello timers:
* Broadcast and P2P: 10 seconds
* NBMA and P2MP: 30 seconds
* Network Types Using 30s Hello Time:
* P2MP (C): OSPF sends Hello packets every 30 seconds by default.
* NBMA (D): OSPF also uses 30 seconds for NBMA networks.
References:
* HCIA-Datacom Study Guide, Chapter: OSPF Network Types
* Huawei OSPF Timer Configuration

NEW QUESTION # 62
Which of the following statements about stack split is false?

A. If the master and standby switches are in two stacks after the split, the stack where the original master switch resides updates the topology and selects a new standby switch. The original standby switch becomes the master switch in the new stack and a new standby switch is elected.
B. After a stack splits, the MAC addresses of the two stacks change immediately.
C. If the master and standby switches are still in the same stack after the stack splits, the slave switches separated from the original master and standby switches re-elect the master and standby switches due to protocol packet timeout.
D. After a stack splits, multiple stacks have the same IP address and MAC address. To prevent network faults, the stacks perform MAD detection. The stack that fails the MAD detection shuts down all physical ports except reserved ports.

Answer: B

Explanation:
When a stack splits, the MAC addresses of the newly formed stacks do not change immediately. Instead, they retain their original MAC addresses until new ones are reassigned during topology updates. This delayed update prevents immediate conflicts and allows MAD (Multiple Active Detection) to handle any resulting issues .

NEW QUESTION # 63
On an OSPF network, if the network type is NBMA, a router unicasts all protocol packets; if the network type is broadcast, a router multicasts all protocol packets.

A. FALSE
B. TRUE

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
* OSPF network types affect how protocol packets (Hello, LSA updates) are transmitted:
* NBMA (Non-Broadcast Multi-Access) networks (e.g., Frame Relay) do not support multicast, so routers must unicast OSPF packets to neighbors.
* Broadcast networks (e.g., Ethernet) support multicast and use 224.0.0.5 for Hello packets and
224.0.0.6 for DR/BDR communication.
* The statement is false because:
* NBMA does not unicast all packets-only Hello packets must be manually configured to be unicast.
* LSAs and routing updates can still be multicast if an NBMA network is configured as point- to-multipoint.
