Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q171-Q176):

NEW QUESTION # 171
OSPF supports area authentication and interface authentication. If both authentication modes are configured, Interface authentication takes preference over area authentication.

A. FALSE
B. TRUE

Answer: B

NEW QUESTION # 172
As shown in the figure, VRRP is associated with a BFD session. When a backup device detects a fault through BFD, the backup device immediately assumes the master role after the Master_Down_Timer timer expires.

A. FALSE
B. TRUE

Answer: A

Explanation:
VRRP and BFD Association:
* VRRP (Virtual Router Redundancy Protocol) is used to provide gateway redundancy by electing a master and backup router.
* Associating VRRP with BFD (Bidirectional Forwarding Detection) allows faster detection of faults on the master device or the link between the master and the backup.

NEW QUESTION # 173
In an OSPF routing domain, two routers must be specified as one DR and one BDR in a broadcast or NBMA network with at least two routers.

A. FALSE
B. TRUE

Answer: B

Explanation:
In an OSPF broadcast or NBMA network with at least two routers, one router must act as the DR (Designated Router), and another as the BDR (Backup Designated Router) to ensure efficient communication and reduce the number of adjacencies. This is a requirement for OSPF operation in such network types .

NEW QUESTION # 174
On the campus OSPF network shown in the following figure, the interfaces connecting the five routers are GE interfaces, and their costs are not changed. The import-route command is run on R1. After the network converges, the route to the server at 192.168.1.0/24 is queried on R2. Which of the following is the cost of this route?

A. 0
B. 1
C. 2
D. 3

Answer: B

Explanation:
Understanding the Network Setup:
* The OSPF network consists of three areas (Area 1, Area 0, and Area 2).
* The server's subnet 192.168.1.0/24 is directly connected to R1 and imported into OSPF using the command:
import-route direct type 1 cost 2
* The type 1 specifies the route as an OSPF Type 1 external route, meaning both the external cost and the internal OSPF cost will be included when calculating the total cost.
* The external cost specified for the imported route is 2.
* Cost Calculation to R2:
* The interfaces between the routers are GE interfaces, and the default cost for GE interfaces is 1.
* The path from R2 to the server goes through the following hops:
* R2 # R1: Cost = 1 (intra-area link).
* R1 # Server: External cost = 2 (specified in the import-route command).
* Total cost to R2:
Intra-area cost (1) + External cost (2) = 3
* Verification of Each Option:
* Option A (2): Incorrect. This only accounts for the external cost, ignoring the internal OSPF cost.
* Option B (4): Incorrect. This overestimates the cost by adding an extra hop.
* Option C (3): Correct. The total cost is 3 (1 for the intra-area link + 2 for the external cost).
* Option D (1): Incorrect. This ignores the external cost of the imported route.

NEW QUESTION # 175
On an OSPF network, interfaces are classified into four types based on link layer protocols. Which of the following types can interfaces on an IS-IS network be classified into based on physical links?

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

Answer: B,C

Explanation:
IS-IS Interface Types
* IS-IS interfaces are categorized based on physical link characteristics:
* Point-to-Point (P2P): Direct connections between two routers.
* Broadcast: Shared medium networks where multiple routers communicate.
Incorrect Options
* C. P2MP and D. NBMA are not standard interface classifications in IS-IS.
HCIP-Datacom-Core Reference
* IS-IS physical link classifications are elaborated in IS-IS link configuration sections.

NEW QUESTION # 176
