Huawei HCIE-Datacom V1.0 Sample Questions (Q171-Q176):

NEW QUESTION # 171
As shown in the figure, R1, R2, and R3 run OSPP at the same time and declare their respective ring ports, as described below is the error.

Answer: A


NEW QUESTION # 172
When you configure a virtualized campus network on iMaster NCE-Campus, Fit APs can immediately go online after you add them to iMaster NCE-Campus.

Answer: A

Explanation:
Comprehensive and Detailed
โœ” Fit APs require additional configurations before going online, such as:
AP authentication and onboarding through DHCP Option 148 or manual registration.
Firmware upgrade and provisioning from iMaster NCE-Campus.
Policy enforcement and VLAN assignment.
Since additional steps are required, Fit APs do not go online immediately, making the statement FALSE.

NEW QUESTION # 173
Which of the following technologies can be used to measure performance based on actual service traffic in Huawei's CloudWAN solution?

Answer: D

Explanation:
Understanding Performance Measurement in Huawei CloudWAN
Huawei CloudWANenables intelligent traffic management,real-time network monitoring, and automated operations.
#Traditional Performance Monitoring Methods
TWAMP (Two-Way Active Measurement Protocol)# Measureslatency and jitterby injecting test traffic.
Telemetry# Providesreal-time network visibility, butdoes not measure actual service traffic performance.
BGP FlowSpec# Used forDDoS mitigation, not performance measurement.
#iFIT (In-situ Flow Information Telemetry)
#iFIT is a next-generation performance monitoring technologythat measures:
Real service traffic performance (latency, jitter, packet loss) in real time.
Packet forwarding behavior at each hop without injecting synthetic traffic.
Path delay and service degradation detection.
Why is Answer D Correct?
#iFIT provides real-time network performance monitoring based on actual service traffic.
#Unlike TWAMP, iFIT does not require probe packets, reducing overhead.
Real-World Application:
5G Transport Networks:Ensureslow-latency paths for ultra-reliable services.
CloudWAN Optimization:Detects network congestionwithout affecting user traffic.
#Reference:Huawei HCIE-Datacom Guide - iFIT and Intelligent Performance Monitoring


NEW QUESTION # 174
NETCONF uses an XML-based encoding format. NETCONF uses text files to represent complex hierarchical data. Which of the following statements are correct about the following XML file?
<?xml version="1.0" encoding="UTF-8"?>
<note>
<to>Learners</to>
<from>Huawei</from>
<heading>Reminder</heading>
<body>Don't forget Reading!</body>
</note>

Answer: A,B,C,D

Explanation:
โœ… A. encoding: indicates the character set encoding format. Currently, only UTF-8 encoding is supported.
UTF-8 is the default and only supported character encoding in NETCONF XML.
โœ… B. /: indicates the end of the current tag.
In XML, </tag> closes an element, defining the end of a structure.
โœ… C. <?: indicates the start of an instruction.
The <?xml line declares an XML document and its version/encoding.
โœ… D. ?>: indicates the end of an instruction.
Closes the XML declaration.

NEW QUESTION # 175
With telemetry, certain data can be sampled based on specific sampling paths. Which of the following sampling paths are supported by telemetry?

Answer: B,C,D

Explanation:
Telemetry Data Collection in Huawei Devices
Telemetry allows real-time streaming of network performance data based on predefined sampling paths. Supported sampling paths include:
โœ… A. Interface statistics
Monitors real-time traffic usage, errors, and packet loss on interfaces.
โœ… C. CPU information
Tracks CPU utilization and performance metrics.
โœ… D. Memory information
Monitors RAM usage and system memory consumption.
โŒ B. Information about the optical module on an interface
Telemetry does not natively support direct optical module monitoring; instead, SNMP or CLI commands like display transceiver are used.
