Huawei HCIE-Datacom V1.0 Sample Questions (Q153-Q158):

NEW QUESTION # 153
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.

NEW QUESTION # 156
On an SR-MPLS network, manually configured prefix SIDs on different devices may conflict with each other.
Assume that there are four routes (prefix/mask SID) as follows. Which of the following routes will be selected according to the conflict handling principle?

Answer: A

Explanation:
InSR-MPLS (Segment Routing over MPLS),prefix SID conflictsmay occur if multiple prefixes are assigned the same SID or vice versa.
Conflict resolution principle (Huawei standard):
When there aremultiple SIDs for the same prefix, theSID with the lowest value wins.
Whenthe same SID is assigned to multiple prefixes, theprefix with the smallest addresswins.
Apply to this case:
Conflict: Two entries for1.1.1.1/32withSID 2 and SID 1.
SID 1 is lower, so1.1.1.1/32 # SID 1is selected.
Correct answer: D. 1.1.1.1/32 # SID 1
