NEW QUESTION # 244
/ifm/interfaces/interface in Huawei Open Programmability System (OPS) is the URL used to identify a device's managed object.
Answer: A
Explanation:
Comprehensive and Detailed In-Depth
In Huawei Open Programmability System (OPS), the URL structure is used to specify managed objects in a standardized way.
The URL path /ifm/interfaces/interface is used in NETCONF/YANG-based APIs to represent interface-related data on a device.
This path allows users to query, configure, or manage network interfaces through programmatic means.
The IFM (Interface Management) model is commonly used for managing network interfaces, and this URL path correctly follows the convention.
Therefore, the statement is TRUE.

Answer: A,C,D
NEW QUESTION # 247
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.
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:
โ
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.
โ 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 # 248
Which of the following statements are correct about the command:
ping -aX -cY -sZ -vpn-instance M 10.5.16.2
Answer: A,B,C,D
Explanation:
Understanding the Command Components:
This is a Huawei CLI command used for diagnosing connectivity within a VPN instance in an MPLS network.
* ping -aX # Specifies the source IP address (X) of the ping packets.
* -cY # Specifies the number of ICMP Echo Request packets to send (Y).
* -sZ # Defines the size (in bytes) of each ICMP Echo Request packet (Z).
* -vpn-instance M # Specifies the VPN instance (VRF) M to which the ping packets belong.
Why are all options correct?
# A. The source IP address of the ping packets is X.
* The -aX option forces the ping to originate from IP X instead of the default interface IP.
# B. The ping packets belong to VPN instance M.
* The -vpn-instance M option ensures the ping is sent within VPN instance M, allowing verification of MPLS L3VPN routing.
# C. During the ping operation, the quantity of ICMP Request packets is Y.
* The -cY parameter sets the number of ICMP Echo Requests to be sent, making Y the total count.
# D. The size of each ICMP Request packet for the ping operation is Z bytes.
* The -sZ parameter defines packet size, helping to test MTU (Maximum Transmission Unit) issues.
Real-World Application:
* Verifying MPLS VPN connectivity: Ensure customer networks are reachable within separate VRFs.
* Testing MTU & fragmentation: Using -sZ, operators can check if packet fragmentation occurs.
* Debugging asymmetric routing issues: By forcing -aX, engineers can trace return paths.
