Huawei HCIE-Datacom V1.0 Sample Questions (Q247-Q252):

NEW QUESTION # 247
A network administrator runs the display telemetry destination command on a device to check information about a destination group that sampled data is sent to. The command output is as follows. Which of the following statements is incorrect?
[~CE-telemetry-sensor-group-Sensor1]display telemetry destination
Dest-name Dest-addr Dest-port State Vpn-name Protocol
Dest1 192.168.56.1 20000 RESOLVED - GRPC

A. VPN encapsulation is used for data push.
B. The gRPC protocol is used for data push.
C. The destination group name is Dest1.
D. The IP address of the destination group is 192.168.56.1

Answer: A

Explanation:
Understanding the Telemetry Output:
Dest-addr: 192.168.56.1#The destination IP address is 192.168.56.1.#
Dest-name: Dest1#The destination group name is Dest1.#
Protocol: gRPC#Data push uses the gRPC protocol.#
Vpn-name: - (empty)#No VPN encapsulation is used.#
Incorrect Answer Explanation:
#C. "VPN encapsulation is used for data push"#Incorrect!
The Vpn-name field isempty, indicating thatVPN encapsulation is NOT enabled for telemetry data transport.

NEW QUESTION # 248
Which of the following statements is incorrect about intranet security design for a large or medium-sized virtualized campus network?

A. Traffic suppression can be configured on the wired network to block broadcast traffic by shutting down interfaces.
B. To secure data transmission, the CAPWAP tunnel between the AC and AP supports DTLS encryption.
C. In addition to terminal access security, air interface security must be considered during wireless network security design.
D. Intranet security refers to both wired and wireless network security.

Answer: A

Explanation:
Comprehensive and Detailed
✔ Traffic suppression is used to control broadcast storms, but shutting down interfaces is NOT the correct way to block broadcast traffic.
✔ Correct Statements:
✅ (B) Intranet security covers both wired and wireless networks.
✅ (C) CAPWAP tunnels use DTLS encryption for security.
✅ (D) Wireless security requires air interface protection against attacks.

NEW QUESTION # 249
Huawei Open Programmability System (OPS) uses standard HTTP methods to access managed objects and manage network devices.
Which of the following HTTP methods is used to configure the value of a network device's managed object?

A. GET
B. PATCH
C. POST
D. PUT

Answer: B

Explanation:
Comprehensive and Detailed
✔ Huawei OPS (Open Programmability System) follows RESTful API principles, using HTTP methods for device management.
✔ HTTP Methods Used in OPS:
✅ GET → Retrieves data from the device.
✅ POST → Creates new data/configurations.
✅ PUT → Replaces entire configuration objects.
✅ PATCH → Updates specific fields of a configuration object. ✅ (Correct Answer) Since PATCH is used for modifying specific values in managed objects, the correct answer is D.

NEW QUESTION # 250
Which of the following statements about RADIUS is correct?( Single choice questions).

A. RADIUS supports both wired and wireless access modes.
B. SEPARATION OF RADIUS PROTOCOL AUTHENTICATION, AUTHORIZATION, AND AUDIT.
C. RADIUS authentication and Portal authentication cannot be used together because the Portal server can typically be used to authenticate users when portal authentication is deployed.
D. MAC authentication does not require a username password, so you cannot use RADIUS to authenticate the user.

Answer: A

NEW QUESTION # 251
The following figure shows some configurations of R1. Based on these configurations, which of the following statements about IS-IS on R1 are correct?
isis 1
is-level level-2
cost-style wide
network-entity 49.0022.ee8c.a0c2.baf1.00
isis 2 vpn-instance tt
is-level level-2
cost-style wide
network-entity 47.00ce.390d.efdc.b3e1.00
isis 3 vpn-instance rr
is-level level-2
cost-style wide
network-entity 47.cc0a.3efb.bbdd.aae1.00

A. Process 1 contains the global routing information and routing information of VRFs tt and rr.
B. Process 1 contains only global routing information.
C. Routing information is shared between processes 2 and 3.
D. Routing information of process 2 is isolated from that of process 3.

Answer: B,D

Explanation:
Let's break this down step-by-step based on Huawei IS-IS VPN and multi-process behavior.
🔹 Configuration Summary:
Process 1: IS-IS for the global routing table
Process 2: IS-IS for VPN instance tt
Process 3: IS-IS for VPN instance rr
✅ Option C: Correct
Process 1 contains only global routing information.
The configuration of isis 1 does not include any vpn-instance keyword, meaning it is bound to the global routing table.
It does not interact with VPN routing tables unless explicitly configured with import/export mechanisms or route leaking (which is not shown here).
Huawei Datacom Reference:
"When an IS-IS process is not associated with a VPN instance, it belongs to the global routing table and only maintains global routes." (Source: HCIE-Datacom Study Guide v3.0 - Chapter: IS-IS for IPv4 and IPv6, Section: Multi-Instance Routing)
✅ Option D: Correct
Routing information of process 2 is isolated from that of process 3.
isis 2 is bound to VPN instance tt
isis 3 is bound to VPN instance rr
Each IS-IS process in Huawei VRF context maintains independent LSDBs and routing tables, and by default, they do not share routing information unless route leaking or redistribution is configured (which is not shown in the config).
Huawei Datacom Reference:
"IS-IS processes bound to different VPN instances operate independently and do not share routing information." (Source: HCIE-Datacom Study Guide v3.0 - Chapter: MPLS L3VPN with IS-IS)
