Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Sample Questions (Q138-Q143):

NEW QUESTION # 138
In an MPLS domain, LSR can be divided into Ingress LSR, Transit LSR and Egress LSR according to the different processing methods of LSRs for dat a. For the same FEC. a certain LSR can be the Ingress LSR of the FEC or the Transit LSR of the FEC. LSRO

  • A. True
  • B. False

Answer: B


NEW QUESTION # 139
On the OSPF network shown in the figure, the cost values of links are marked. OSPF IP FRR is enabled on R1, and the maximum load-balancing 8 command is configured in the OSPF process. If a service passes through the path R1 # R5 # R3 to reach 10.0.3.3/32, which of the following is the backup outbound interface for the service?

  • A. GE0/0/3
  • B. GE0/0/2 and GE0/0/3
  • C. There is no backup outbound interface.
  • D. GE0/0/2

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Step 1: Identify the Primary Path
* The shortest OSPF cost to 10.0.3.3/32 from R1 is through R5:
* R1 # R5 (Cost 10) # R3 (Cost 10) = Total Cost 20
* The primary outbound interface from R1 to R5 is GE0/0/1.
Step 2: Identify the Backup Path (OSPF IP FRR & ECMP)
* OSPF IP Fast Reroute (FRR) provides a backup next-hop in case the primary link (R1 # R5) fails.
* A feasible backup path must have a cost equal to or close to the primary path, but it must avoid the same failure point.
Alternative Path Calculation:
* Path 1 (R1 # R2 # R3)
* R1 # R2 (Cost 10), R2 # R3 (Cost 10) # Total Cost = 20 #
* Uses interface GE0/0/2 on R1.
* Path 2 (R1 # R4 # R3)
* R1 # R4 (Cost 10), R4 # R3 (Cost 10) # Total Cost = 20 #
* Uses interface GE0/0/3 on R1.
Final Decision on the Backup Interface
* Since both paths R1 # R2 # R3 and R1 # R4 # R3 have equal costs, either can be used for backup.
* However, R1 # R2 # R3 shares a direct cost path with R5, meaning it may not be preferred as a full FRR backup.
* The best backup outbound interface in this scenario is GE0/0/3 (R1 # R4 # R3).
Final answer: # C (GE0/0/3)

NEW QUESTION # 140
The figure shows the output information on a switch.
Which of the following can be determined from the information?

  • A. When the average rate of known unicast packets is 2500 pps, GE0/0/1 is shut down.
  • B. After broadcast packets are blocked on GE0/0/1, broadcast packets are forwarded only when their average rate is lower than 1000 pps.
  • C. When the average rate of unknown multicast packets is 1500 pps, GE0/0/1 blocks the multicast packets.
  • D. The administrator configures traffic suppression on GE0/0/1 of the switch.

Key Observations from the Table:
* Traffic suppression (or rate limiting) is configured on interface GE0/0/1 for broadcast, multicast, and unicast traffic.
* Thresholds:
* Min rate: 1000 pps (packets per second)
* Max rate: 2000 pps
* If the traffic exceeds the configured threshold (2000 pps), the action is to "Block".
* The interface is still "Normal" (not shut down), meaning exceeding 2000 pps does not disable the port.
* Logging is enabled (Log: On), but trapping (Trap: Off) is disabled.
Analysis of Each Answer Choice
A: "When the average rate of unknown multicast packets is 1500 pps, GE0/0/1 blocks the multicast packets." # (False)
* The blocking threshold for multicast is 2000 pps (Max rate).
* If the rate is 1500 pps, it is still below the threshold, so traffic is not blocked yet.
# Statement A is incorrect.
B: "When the average rate of known unicast packets is 2500 pps, GE0/0/1 is shut down." # (False)
* The table does not indicate that exceeding the max threshold (2000 pps) shuts down the interface.
* Instead, it simply blocks packets exceeding the rate limit.
* The interface remains "Normal", meaning it is not shut down.
# Statement B is incorrect.
C: "After broadcast packets are blocked on GE0/0/1, broadcast packets are forwarded only when their average rate is lower than 1000 pps." # (False)
* The minimum rate is 1000 pps, but there is no indication that traffic resumes forwarding only when it drops below this rate.
* The configuration only states blocking when exceeding 2000 pps, but does not enforce a strict reactivation at 1000 pps.
# Statement C is incorrect.
D: "The administrator configures traffic suppression on GE0/0/1 of the switch." # (True - Correct Answer)
* The table explicitly shows that a traffic suppression policy is applied to broadcast, multicast, and unicast packets on GE0/0/1.
* This confirms that the administrator has configured traffic suppression (rate limiting) on this interface.
# Statement D is correct.
Final Conclusion:
# Correct answer: D. The administrator configures traffic suppression on GE0/0/1 of the switch.


NEW QUESTION # 141
In an MPLS VPN network, data packets are forwarded when they enter the public network. Will be encapsulated with two layers of MPLS labels.
