質問 # 128
For Layer 2 VPN technology, the following statement is correct?( Multiple choice questions).

A. The VPLS configuration is complex and the Layer 2 network transmits BUM packets.
B. BGP EVPN supports features such as tenant isolation, Multi-homing , and broadcast suppression.
C. BGP EVPN addresses issues such as MAC address drift and multi-tenancy that VPLS cannot support.
D. VPLS is a widely used technology in the live network, which can provide transparent transmission of three-layer messages and achieve multi-point access.

正解：A、B

質問 # 129
Network Quality Analysis (NQA) is a real-time network performance detection and measurement technology.
It monitors the performance of multiple protocols running on a network. Which of the following protocols can be monitored by NQA?

A. DHCP
B. SNMP
C. OSPF
D. ICMP

正解：D

解説：
Huawei'sNQA (Network Quality Analysis)provides tools to test and monitor network performance such as latency, jitter, and packet loss. The supported test types include:
ICMP- For reachability and round-trip time testing.
UDP,TCP,HTTP,FTP, etc.
DNS,VoIP,DHCP(limited to simulation, not monitoring protocol status itself) Protocols likeSNMPandOSPFarenot directly monitored by NQA, as these aremanagement or control plane protocols, not data-path or performance-measurable protocols.
Correct answer: C. ICMP

Supported Detection Protocols and Applications

質問 # 130
In a multicast network running PIM-SM mode, how does the router choose the upstream interface?

A. Interfaces to which multicast group members are directly connected
B. looks up the outgoing interface corresponding to the RP address in the unicast routing table
C. Find the outbound interface corresponding to the mapping proxy in the unicast routing table
D. Interface for sending PIM Heilo messages.
E. The interface that is fast to the PIlM Join message

正解：B

質問 # 131
The Ingress VTEP performs both Layer 2 and Layer 3 table lookup for packet forwarding. The forwarding mode is ______ IRB forwarding.

正解：

解説：
(Capitalize the first letter.) IntegratedInVXLAN routing, there are two primary IRB forwarding modes:Integrated IRB forwarding: Both Layer 2 and Layer 3 lookups are performed at theIngress VTEPfor more efficient forwarding.Distributed IRBis another mode, but in this scenario, where both L2 and L3 lookups are needed at the Ingress VTEP, the correct mode isIntegrated.Correct answer: Integrated

質問 # 132
In the figure,SR-MPLSis enabled onR1, R2, and R3. TheSRGB (Segment Routing Global Block) rangeonR3is from20000 to 21000, and theprefix SID indexconfigured on theloopback1 interface of R3 is 30.
In this case, theMPLS label corresponding to the loopback1 interface of R3 is _____.
(Enter anArabic numeralwithout symbols.)

正解：

解説：
20030
Explanation:
Understanding SR-MPLS Label Calculation
SR-MPLS usesSegment Routing Global Block (SRGB)andPrefix SIDsto assign labels dynamically.
TheMPLS labelfor a node's loopback interface is calculated as follows:
MPLS Label=SRGB Base+Prefix SID Index
Where:
SRGB Base=20000(as given in the figure)
Prefix SID Index=30(configured for R3's Loopback1)
Label Calculation:
20000+30=20030
Thus, theMPLS label corresponding to the loopback1 interface of R3 is 20030.
Why the Answer is 20030?
#The SRGB defines the base label range.
#Each router is assigned a unique Prefix SID index.
#The label is dynamically computed by adding the Prefix SID Index to the SRGB Base.
Why Other Numbers Are Incorrect?
#Any value outside the range 20000-21000
Would be incorrect because it must be withinR3's SRGB range.
#Using the Prefix SID Index directly (30)
Incorrect becauseMPLS labels are not assigned directly using Prefix SIDs; they are computed using the SRGB.
