Huawei HCIE-Datacom V1.0 Sample Questions (Q56-Q61):

NEW QUESTION # 56
The following statement about the IS-IS protocol is incorrect?

  • A. The IS-IS protocol is a link-state protocol that runs between AS
  • B. Messages for the IS-IS protocol are encapsulated directly by the data link layer
  • C. The IS-IS protocol supports CLNP networks
  • D. The IS-IS protocol supports IP network ad

Answer: A


NEW QUESTION # 57
Network administrator A wants to use an IP prefix-list to match specific routes. Which of the following routes can be matched by the IP prefix-list shown in this figure?
ip ip-prefix TEST permit 10.0.0.0 24 less-equal 30

  • A. 10.0.2.0/24
  • B. 10.0.1.0/24
  • C. 10.0.0.0/24
  • D. 10.0.0.1/30

Answer: C,D

Explanation:
Understanding Prefix Lists
* IP Prefix-Lists are used for filtering BGP routes and controlling route advertisement & redistribution.
* The command ip ip-prefix TEST permit 10.0.0.0 24 less-equal 30 means:
* Matches prefix 10.0.0.0/24 exactly.
* Matches any subnet of 10.0.0.0/24 with a prefix length between 24 and 30.
Analysis of Routes:
* # 10.0.0.0/24 # Matches exactly.
* # 10.0.0.1/30 # Falls within 10.0.0.0/24 & length #30.
* # 10.0.1.0/24 # Not within 10.0.0.0/24 range.
* # 10.0.2.0/24 # Not within 10.0.0.0/24 range.
Real-World Use Case:
* BGP route filtering: Only allows 10.0.0.0/24 and its subnets (up to /30).
* Prevents unintended route propagation in large-scale networks.

NEW QUESTION # 58
Telemetry data must be encoded in GPB binary format. This format reduces the number of bytes in telemetry messages and improves the transmission efficiency compared with messages encoded in JSON format.

  • A. TRUE
  • B. FALSE

Answer: B

Explanation:
Understanding Telemetry Encoding Formats
# What is Telemetry?
* Telemetry is a real-time network monitoring method that provides high-frequency data collection.
* Used in AI-driven networks for predictive analytics and automation.
# Common Telemetry Encoding Formats:
# GPB (Google Protocol Buffers)
* Highly efficient binary format that reduces message size and CPU overhead.
* Commonly used for high-speed, real-time analytics.
# JSON (JavaScript Object Notation)
* Human-readable format, widely used in RESTful APIs.
* Less efficient than GPB in high-speed telemetry but easier to debug.
# Why is the Answer FALSE?# GPB is not mandatory; JSON can also be used in telemetry.# Huawei supports both GPB and JSON telemetry encoding formats.
Real-World Application:
* Cloud Networking: Uses GPB for fast data collection and JSON for API-based telemetry visualization.
* AI-Driven Networks: High-speed AI analytics leverage GPB encoding for efficiency.

NEW QUESTION # 59
Which of the following statements regarding RT are correct?

  • A. The RT value is advertised to neighbors through the BGP extended community attribute in Update messages.
  • B. Each VPN instance is associated with one or more pairs of VPN Target attributes, used to control VPN routing information advertisement and reception between sites.
  • C. Export Target and Import Target are independent of each other and support multiple values to implement flexible VPN routing information advertisement and reception control.
  • D. RTs are classified into two types: Export Target and Import Target.

Answer: A,B,C,D

Explanation:
Route Target (RT) is a BGP extended community attribute used in MPLS Layer 3 VPNs (L3VPNs) to control the import and export of VPN routes between different VPN instances (VRFs).
Explanation of Correct Answers:
# A. Each VPN instance is associated with one or more pairs of VPN Target attributes, used to control VPN routing information advertisement and reception between sites.
* Each VRF (VPN Routing and Forwarding instance) has an associated RT that determines which routes are imported and exported between VPNs.
* RTs enable inter-VPN communication while maintaining separation between VPN customers.
# B. Export Target and Import Target are independent of each other and support multiple values to implement flexible VPN routing information advertisement and reception control.
* The Export RT specifies which routes should be advertised.
* The Import RT specifies which routes should be accepted into a VRF.
* These can be configured independently to control traffic flow between VPNs.
# C. RTs are classified into two types: Export Target and Import Target.
* Export Target: Defines which VPN routes are advertised.
* Import Target: Defines which VPN routes are accepted.
* A VPN instance can have multiple RTs to allow flexibility.
# D. The RT value is advertised to neighbors through the BGP extended community attribute in Update messages.
* RTs are carried in BGP UPDATE messages as part of the BGP extended community attribute, enabling VPN route exchange between PEs.

NEW QUESTION # 60
Man-in-the-middle attacks (MITM) or IP/MAC Spoofing attacks are common on intranets and can cause information leakage.
Which configuration method can prevent these attacks?

  • A. Limit the maximum number of MAC addresses that can be learned on a switch interface.
  • B. Configure the trusted or untrusted interface.
  • C. Configure association between DHCP snooping and IPSG or DAI on the switch.
  • D. Configure DHCP snooping to check the CHADDR field carried in a DHCP Request packet.

Answer: C

Explanation:
Comprehensive and Detailed Explanation:
# The Best Protection Against MITM and Spoofing Attacks:# (D) Associating DHCP Snooping with IPSG (IP Source Guard) and DAI (Dynamic ARP Inspection) provides complete protection by:
* Blocking rogue DHCP servers.
* Preventing MAC/IP spoofing.
* Ensuring only valid clients access the network.
# Why Not Other Options?# (A) Configuring trusted/untrusted interfaces only helps block rogue DHCP servers, but does not prevent spoofing.# (B) Limiting MAC address learning prevents MAC flooding, but does not stop MITM attacks.# (C) Checking the CHADDR field in DHCP Snooping helps detect spoofed requests, but does not block all MITM scenarios.
