Huawei HCIE-Datacom V1.0 Sample Questions (Q161-Q166):

NEW QUESTION # 161
In an MPLS VPN network, two-layer MPLS labels are added into data packets before they are transmitted over the public network. Which of the following statements regarding data packet processing are correct?

A. The IP data packet received by egress LSR is without labels.
B. The penultimate hop removes the outer label before forwarding the data packet to a peer egress PE.
C. The penultimate-hop device receives a packet with an outer label.
D. The egress PE sends the data packet to the correct VPN based on the inner label.

Answer: B,C,D

Explanation:
In MPLS VPN, packets are forwarded using two labels:
Outer label (Transport Label) - Used by the MPLS backbone for forwarding.
Inner label (VPN Label) - Used by the egress PE to identify the correct VPN instance.
Explanation of Correct Options:
✅ A. The egress PE sends the data packet to the correct VPN based on the inner label.
The inner label is assigned by the egress PE and determines the final destination VPN instance.
✅ B. The penultimate hop removes the outer label before forwarding the data packet to a peer egress PE.
Penultimate Hop Popping (PHP) occurs when the second-to-last router (P router) removes the outer MPLS label before forwarding to the egress PE.
This reduces the processing overhead on the egress PE.
✅ D. The penultimate-hop device receives a packet with an outer label.
The outer label is used to forward the packet across the MPLS backbone.
Before reaching the egress PE, the penultimate router still has the outer label and processes it.
Incorrect Option:
❌ C. The IP data packet received by the egress LSR is without labels.
This is incorrect because the inner label (VPN label) is still present when the packet reaches the egress PE.
Only the outer label is removed by PHP, not the inner VPN label.

NEW QUESTION # 162
The following information about MPLS tags describes the error as ?( Single choice questions).

A. When the tag value is 0, the tag must be ejected and the message must be forwarded based on IPv4
B. If the bottom of the label identifies S=0, it indicates that the label is the bottom label and is directly forwarded to the IP.
C. By default, devices support php features, and the ERAS node that supports PHP assigns a tag value of 3 to the penultimate hop node
D. The MPLS tag is 4 bytes long and encapsulated between the link layer and the network layer.

Answer: B

NEW QUESTION # 163
The following about BGP routing, what is the wrong description?

A. For next_hop unreachable routes are invalid cat by and do not participate in the preference. Flogging case
B. See the following entry in the BGP routing table: * *17 16 1. 11/32 0 00010 0? Indicates that the route is available non-optimal.
C. In the case of PrefVal, Local_Preference equality, if the BGP preference of the locally generated route, IBGP route, EBGP route is equal, the valid reference of this generation is preceded by priority.
D. Non-aggregate routes take precedence over aggregate routes.

Answer: D

NEW QUESTION # 164
In DU label advertisement mode, if the liberal label retention mode is used, the device reserves labels received from all the LDP peers regardless of whether the LDP peer is the optimal next hop for reaching the destination network.

A. TRUE
B. FALSE

Answer: A

Explanation:
In MPLS LDP (Label Distribution Protocol), label retention modes control how labels are stored in the Label Forwarding Information Base (LFIB).
DU Label Advertisement Mode (Downstream Unsolicited):
* Labels are advertised to all LDP peers without a request.
* The receiving router decides which label to use for forwarding.
Liberal vs. Conservative Label Retention:
# Liberal Label Retention Mode (Correct Answer)
* All received labels from all LDP peers are stored.
* Even if a peer is not the optimal next hop, its label is retained.
* Allows faster convergence during failures.
# Conservative Label Retention Mode
* Only the label from the best next-hop peer is stored.
* Reduces memory usage but can slow down convergence in case of failure.

NEW QUESTION # 165
What is the following description of MPLS BGPVPN incorrect?

A. The routing exchange between PE-CE can be static routing, OSPF multi-instance, IS-IS multi-instance, EBGP
B. IBGP PEes generally use the Loopback interface address to establish a stable BGP neighbor relationship
C. The TTL field in the label has the effect of preventing loops.
D. BGP So0, which is used to prevent routes issued from a VPN site from passing through the MPLS backbone and back to that site. So0 is an extended group attribute that MP-BGP automatically generates.

Answer: D
