Huawei HCIE-Datacom V1.0 Sample Questions (Q236-Q241):

NEW QUESTION # 236
The display current-configuration command displays the running configurations in memory.

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
The display current-configuration command is used to show the active running configuration stored in RAM (memory).
Key Features:
# Displays current settings for interfaces, routing, and security.# Reflects real-time changes (different from startup-config stored in NVRAM).# Useful for troubleshooting and verification before saving configurations.
Thus, the statement is TRUE.
# Reference: Huawei HCIE Datacom - Command Reference Guide


NEW QUESTION # 237
Link state information is isolated by default between different IS-IS processes on the same router.

  • A. FALSE
  • B. TRUE

Answer: B


NEW QUESTION # 238
Refer to the figure.

Which of the following steps are mandatory to enable 802.1X authentication on GE0/0/2 and GE0/0/3 of SW3 and configure a RADIUS server to authenticate and deliver network access rights to users?

  • A. Configure an AAA scheme.
  • B. Configure an authentication domain.
  • C. Configure an 802.1X access profile.
  • D. Configure an authentication profile.

Answer: A,B,C,D

Explanation:
Understanding 802.1X Authentication in Enterprise Networks
# What is 802.1X?
* 802.1X is a network access control (NAC) protocol that enforces authentication before allowing a device to connect to a LAN.
* It uses EAP (Extensible Authentication Protocol) over RADIUS for user verification.
* Typically deployed in corporate and campus networks for secure wired and wireless access.
# How Does 802.1X Work?1## Client (Supplicant) # Requests network access.2## Switch (Authenticator) # Forwards request to RADIUS server.3## RADIUS Server # Verifies credentials & grants access.
Mandatory Steps to Enable 802.1X on SW3
# A. Configure an AAA Scheme
* Defines authentication, authorization, and accounting (AAA) methods.
* Links 802.1X authentication to the RADIUS server.
# B. Configure an Authentication Profile
* Specifies how authentication is handled on the switch.
* Associates 802.1X authentication with an AAA scheme.
# C. Configure an Authentication Domain
* Groups authentication policies for different user types.
* Maps AAA scheme to user login requests.
# D. Configure an 802.1X Access Profile
* Applies 802.1X authentication to specific switch ports (GE0/0/2 & GE0/0/3).
* Ensures that only authenticated users can pass traffic.
Why Are All Four Steps Necessary?
# Each step plays a critical role in enabling 802.1X authentication and linking it to the RADIUS server.
# Without any one of these configurations, the 802.1X authentication process would fail.
Real-World Application:
* Enterprise Wired Security: Ensures that only authenticated devices access corporate networks.
* University Campuses & Public Wi-Fi: Prevents unauthorized access to secure LAN environments.

NEW QUESTION # 240
The channelized sub-interface and FlexE technologies both can be used to implement network slicing, but the application scenarios of the two technologies are slightly different. Which of the following statements about the two technologies are correct?

  • A. It is recommended that FlexE be used to reserve resources for 50GE and higher-rate interfaces.
  • B. Only network slicing based on channelized sub-interface can be deployed across MSTP devices.
  • C. Only FlexE-based network slicing can be deployed across OTN devices.
  • D. It is recommended that channelized sub-interface be used to reserve resources for interfaces with a bandwidth of less than 50 Gbit/s.

Answer: A,C,D

Explanation:
Network Slicing Using Channelized Sub-Interfaces and FlexE
Both channelized sub-interfaces and FlexE (Flexible Ethernet) are used for network slicing, but they have different application scenarios:
# A. Channelized sub-interface is recommended for interfaces with bandwidth < 50 Gbit/s.
* Channelized sub-interfaces split a physical interface into multiple logical sub-interfaces.
* Best for lower-bandwidth links (<50 Gbit/s).
# B. FlexE is recommended for 50GE and higher-rate interfaces.
* FlexE divides a high-bandwidth physical link (e.g., 100GE, 400GE) into multiple virtual slices.
* Used in high-speed backbone and data center networks.
# C. Only FlexE-based network slicing can be deployed across OTN devices.
* FlexE is compatible with Optical Transport Network (OTN) and can be used for long-haul slicing across OTN.
# D. Only channelized sub-interface-based network slicing can be deployed across MSTP devices.
* Incorrect! While MSTP supports channelized interfaces, FlexE is not restricted to MSTP deployment
